Bagaimana Tinta Printer Inkjet Dibuat ?

noreply@blogger.com (Rio) — Thu, 28 Jul 2011 06:31:00 +0000

Banyak orang yang berusaha mencari tahu bahan dasar dari tinta printer yang dijual dipasaran dengan berbagai macam tujuan. Salah satu diantaranya yaitu keinginan untuk membuat sendiri tinta printer baik untuk digunakan sendiri maupun dijual kembali.

Apa yang akan saya informasikan berikut ini hanya secara garis besar saja karena tidak bertujuan mengajarkan bagaimana membuat tinta printer tapi adalah untuk menginformasikan apa saja yang terkandung dalam tinta printer. Karena setelah kita tahu apa saja yang terkandung pada tinta, kita menjadi semakin mengerti bagaimana seharusnya merawat dan memanfaatkan printer.

Bagi yang sudah mengetahui jenis tinta printer pasti sudah pernah mendengar istilah tinta Dye dan Pigment, sebetulnya kedua jenis ini sama-sama berbahan dasar air. Namun saya hanya akan membahas jenis tinta Dye.

Setiap perusahaan tinta mempunyai bahan tambahan yang menjadi kekuatan jual produk mereka, tetapi pada intinya tinta mempunyai bahan dasar yang harus ada untuk memproduksinya. Semua bahan ini dicampur menjadi satu.
Bahan dasar tinta jenis Dye :
1.    Air
Air yang digunakan adalah harus air dengan kualitas tinggi, tidak terkontaminasi baik sejak pengambilan hingga pemrosesan tinta, kualitas air menentukan daya tahan tinta nantinya saat penyimpanan, biasanya air ini harus melalui proses UV dan Reverse Osmosis, ada juga yang menggunakan air destilasi. Air adalah komponen terbanyak yang digunakan untuk membuat tinta Dye.
2.    Pewarna
Pewarna Jenis Dye yang terbaik adalah pewarna yang mampu menampilkan kualitas warna yang baik.
3.    Co-Solvent – Humectant
Adalah bahan cair yang membantu pewarna(bukan tinta keseluruhan) agar tidak mudah mengeras sebelum terserap oleh kertas.
4.    Fixative – Penetrant
Adalah bahan yang mengontrol tinta saat jatuh pada permukaan kertas, bahan ini harus mampu menahan tinta agar tidak terlalu terserap oleh kertas yang dapat mengakibatkan tinta tembus ke belakang kertas atau basah sebelum mengering.
5.    Surfactant.
Adalah bahan cair pemacu kerja tinta keluar dari head catridge, ukuran yang salah dalam penggunaannya menghasilkan tinta yang buruk. Humectant yang terlalu banyak bisa membuat tinta terus-menerus keluar dari head (wicking), atau terlalu sedikit juga bisa membuat tinta mudah menggumpal pada tangki dan head menjadi tersumbat (clogging). Pemakaian Surfactant harus seimbang dengan penggunaan Fixative.
6.    Resin
Bahan inilah yang membuat efek polish dan tidak mudah terberai saat hasil cetakan pada kertas kita gosok dengan tangan.
7.    Biosida/Fungisida
Adalah bahan tambahan untuk menjaga keawetan tinta saat disimpan pada waktu yang lama dengan membunuh kuman dan bakteri pada tinta.
8.    Buffer dan Agent lainnya
Biasanya tinta harus memiliki pengatur pH agar tinta tidak terlalu asam atau basa.

Itulah bahan-bahan dasar dalam pembuatan tinta printer jenis Dye.
Saya yakin setelah mengetahui bahan-bahan dasar tinta ini, kita bisa mengetahui penyebab tinta wicking atau clogging, tinta yang jamuran, tinta yang berwarna pudar, dan lainnya.

Mohon maaf tidak menampilkan informasi takaran dan merek-merek dari bahan yang disebutkan diatas.

Sumber : Disadur kembali dari berbagai sumber.

Apakah kita bisa membuatnya ?
Melihat proses demi proses pembuatan tinta yang memerlukan pengetahuan yang cukup tentang ilmu kimia, ilmu daya serap kertas, dan karakteristik tiap bahan dasar serta alat-alat pengukur lainnya yang akurat dan percobaan berulang-ulang maka memang ada baiknya pembuatan tinta dipercayakan pada perusahaan industri, cukup sulit untuk melakukannya pada rumah tangga, karena sangat menentukan kualitas tinta yang dihasilkan.

Bisnis Digital Printing

noreply@blogger.com (Rio) — Tue, 05 Jul 2011 06:53:00 +0000

Sepertinya bisnis digital printing tidak ada habisnya, beberapa orang mulai dari nol alias tanpa latar belakang pengetahuan dan pengalaman di bidang ini, beberapa ada yang dengan modal minim bersaing dengan yang profesional dan modal besar, dan berhasil. Hampir setiap hari disemua sudut jalan yang saya lewati adalah tulisan dan gambar hasil digital printing yang 10 tahun lalu itu adalah media promosi yang mahal. Tapi sekarang, semuanya bisa dicetak dalam waktu yang singkat.

Meskipun sekarang sudah banyak usaha jasa percetakan dan digital printing, namun saya melihat masih besar sekali peluang untuk terjun di bisnis ini. Bagi yang tertarik mungkin bisa mencoba usaha jasa cetak digital ini secara kecil-kecilan, atau kalau tidak bisa sebagai penyedia alat-alat teknologi yang mendukung usaha cetak digital ini. Memang luas sekali cakupan dari usaha cetak digital ini, tinggal kita memperhitungkannya hendak terjun pada bagian mana.

Sampai-sampai saya juga tertarik untuk membangun usaha dibidang ini.

Saya Menggunakan Antivirus Microsoft Security Essentials (MSE)

noreply@blogger.com (Rio) — Fri, 10 Jun 2011 06:00:00 +0000

Saat ini saya menggunakan antivirus Microsoft Security Essentials (MSE) yang dibuat oleh microsoft, penginstalannya mudah, bagi yang ingin menggunakannya juga sebaiknya secara online melalui situs resmi microsoft, karena walaupun bisa diinstall secara offline pada akhirnya antivirus ini membutuhkan update database antivirusnya secara online sebelum MSE berjalan secara realtime untuk memproteksi komputer/notebook, Antivirus ini masih gratis disediakan oleh microsoft.

Pertama kali MSE melakukan scanning pada laptop saya, ditemukan virus-virus parasit yang menumpang pada file-file system, hal ini mengejutkan saya karena tidak tanggung-tanggung virus ini juga ditemukan sampai ke folder “system32” menyerang aplikasi windows seperti notepad.exe, calculator.exe, dan lainnya. Setelah ditemukan MSE merekomendasikan melakukan aksi ‘remove’ untuk membersihkannya, dan hasilnya memuaskan.

Yang membuat saya aman menggunakan MSE adalah karena dibuat oleh Microsoft sendiri sebagai pembuat sistem operasi yang saya gunakan, yang tentu lebih mengerti file-file asing yang dapat mengganggu sistem operasi bekerja. Selain itu saya menggunakan MSE berdampingan dengan aplikasi Internet Security buatan COMODO sehingga lebih aman terproteksi saat online.

Hati-hati Membuka Email Yahoo Anda !

noreply@blogger.com (Rio) — Wed, 25 May 2011 14:38:00 +0000

Baru-baru ini saya menerima email-email tanpa subjek dari teman-teman saya yang merasa bahwa mereka tidak mengirimnya, dan Isi dari email-email tersebut semuanya memiliki bentuk yang sama yaitu hanya berisi satu buah alamat web yang panjang dalam bahasa asing dan mengandung hiperlink , saya pun penasaran mengklik link tersebut yang ternyata tidak menuju kemana-mana alias “the page are not found” pada browser saya, demikian juga email-email lain yang tanpa subjek yang juga berisi hanya sebuah alamat link.

Sejak saya menerima dan mengklik-klik isi email mencurigakan itu, teman-teman saya sering bertanya pada saya, email apakah yang kamu kirim kemarin ? tentu saja saya terkejut karena saya tidak pernah mengirim email pada teman-teman saya yang bertanya itu, setelah saya tanya apa isi dari email yang saya kirim ternyata adalah sebuah alamat web dengan link yang tidak menuju kemana-mana, dan anehnya setiap email dengan alamat web yang berbeda-beda.

Dari peristiwa inilah, saya mencurigai bahwa email yang tanpa subjek yang saya terima sebelumnya mengandung program jahat yang mencuri kontak address email teman-teman saya dan mengirimkan secara otomatis email yang tidak pernah kita kirim. Sejak saat itu semua email yang tanpa subjek, sekalipun itu dari teman saya langsung saya hapus dari inbox tanpa harus membukanya dahulu karena tidak mau ambil resiko lebih buruk.

Saran saya pada teman-teman yang mempunyai akun email yahoo, jangan pernah membuka email tanpa subjek (tanpa judul atau tema email) yang biasanya hanya tertulis “[NO SUBJECT]” , LANGSUNG HAPUS SAJA !, kalau sudah terlanjur membukanya jangan pernah mengklik alamat web yang mengandung link didalamnya.

Jika Email itu dari teman-teman Anda dan penting, pasti teman anda akan menuliskan subjek dari email mereka.

Berikut contoh email yang mencurigakan yang sering saya terima.

Symantec: Serangan Mengincar Perangkat Bergerak

noreply@blogger.com (Rio) — Fri, 29 Apr 2011 15:09:00 +0000

JAKARTA, KOMPAS.com - Laporan terbaru Symantec Internet Security Threat Report (ISTR) mengindikasikan potensi naiknya ancaman serangan ke perangkat bergerak. Hal tersebut didorong semakin maraknya pengguna platform perangkat bergerak sehingga menarik perhatian penyerang.
Laporan ini berasal dari data yang dikumpulkan oleh puluhan juta sensor internet, riset langsung, dan pemantauan komunikasi aktif para hacker. Tujuannya untuk memberikan wawasan global mengenai kondisi Keamanan Internet. Waktu penelitian ISTR Volume 16 ini dimulai sejak Januari 2010 hingga Desember 2010.

"Kita tidak bisa memungkiri bahwa kehidupan kita sudah dilingkupi dengan aktifitas yang menggunakan teknologi informasi. Gadget seperti handphone, laptop, iPad, Galaxy Tab, atau apa pun itu, sudah menjadi benda yang wajib kita bawa ke mana-mana. Kita bisa online di mana saja, bersosialiasi di dunia maya kapan saja," ujar Darric Hor, General Manager Symantec untuk Indonesia dan Filipina, dalam konferensi pers Symantec Symposium 2011 "Be Prepared To Take Control" di Grand Hyatt Hotel, Jakarta, Rabu (27/4/2011).
Symantec melaporkan, pada tahun 2010, kebanyakan serangan program berbahaya (malware) terhadap perangkat bergerak adalah program Trojan Horse yang menyamar sebagai aplikasi sah/asli. Meskipun penyerang membuat beberapa malware yang sama sekali baru, pada banyak kasus, mereka menginfeksi pengguna dengan memasukkan malicious logic ke dalam aplikasi asli yang ada. Penyerang lalu mengirimkan aplikasi terinfeksi ini melalui app store publik.
Misalnya, pembuat Pjapps Trojan baru-baru ini menggunakan pendekatan tersebut. Meskipun arsitektur keamanan baru yang digunakan dalam perangkat bergerak saat ini sudah sama efektifnya dengan yang sudah menyerang desktop dan server, penyerang sering kali dapat melewati perlindungan ini dengan menyerang kerentanan bawaan dalam implementasi platform bergerak tersebut. Sayangnya, kekurangan tersebut umum terjadi. Symantec mendokumentasikan 163 kerentanan selama tahun 2010 yang bisa digunakan penyerang untuk dapat mengendalikan sebagian atau keseluruhan perangkat yang menggunakan platform bergerak terkenal.
Dalam beberapa bulan pertama tahun 2010 penyerang telah memanfaatkan kelemahan ini untuk menginfeksi ratusan ribu perangkat berbeda. Berdasarkan temuan, tidak mengejutkan jika 47 persen organisasi/perusahaan tidak yakin mereka dapat secara efektif mengontrol resiko yang disebabkan oleh perangkat bergerak. Dan, bahwa lebih dari 45 persen organisasi/perusahaan mengatakan masalah keamanan merupakan salah satu hambatan terbesar untuk meluncurkan lebih banyak perangkat pintar.
Serangan Terarah
Tingginya aktivitas penggunaan teknologi informasi juga mendorong meroketnya ancaman cyber yang semakin canggih. Maka, sorotan utama dalam laporan ini antara lain adalah peningkatan dramatis baik dalam frekuensi maupun kecanggihan dari serangan terarah di lingkungan enterprise; terus meningkatnya situs jejaring sosial sebagai tempat penyebaran serangan; dan perubahan taktik infeksi penyerang, yang semakin menargetkan kerentanan dalam Java guna menerobos masuk ke sistem komputer tradisional.
"Sifat dari ancaman telah semakin luas mulai dari menyasar rekening perorangan pada suatu bank hingga menyasar informasi dan infrastruktur fisik suatu negara," kata Raymond Goh, Regional Technical Director Systems Engineering, Symantec. "Skala serangan-serangan ini pun sangat beragam, mulai dari perusahaan multinasional yang terdaftar di bursa dan lembaga pemerintahan hingga perusahaan-perusahaan berskala kecil dan pengguna komputer perorangan." tambah Raymond.
Serangan terarah seperti Hydraq dan Stuxnet menyebabkan meningkatnya ancaman di lingkungan enterprise pada tahun 2010. Untuk meningkatkan peluang agar berhasil masuk ke dalam enterprise tanpa terdeteksi, semakin banyak serangan terarah ini memanfaatkan kerentanan zero-day untuk masuk ke sistem komputer.
Sebagai salah satu contoh, Stuxnet sendiri dapat mengeksploitasi empat kerentanan zero-day berbeda untuk menyerang sasarannya. Pada tahun 2010, penyerang meluncurkan serangan terarah ke berbagai perusahaan multinasional yang terdaftar di bursa saham dan lembaga-lembaga pemerintahan, serta perusahaan-perusahaan yang angkanya cukup mengejutkan.
Dalam banyak kasus, penyerang meneliti korban-korban utama di masing-masing perusahaan dan kemudian menggunakan serangan rekayasa sosial (social engineering) yang disesuaikan untuk dapat masuk ke jaringan korban. Karena sifatnya yang terarah, banyak dari serangan ini berhasil bahkan saat organisasi/perusahaan yang menjadi korban telah memiliki prosedur keamanan dasar yang sudah diterapkan.
Meskipun serangan terarah tingkat tinggi pada tahun 2010 berusaha untuk mencuri kekayaan intelektual atau mengakibatkan kerusakan fisik, banyak serangan terarah juga mengincar perorangan untuk mendapatkan informasi pribadi mereka.
Sebagai contoh, laporan ini mengungkapkan bahwa pelanggaran data yang disebabkan oleh hacking berhasil mencuri rata-rata lebih dari 260.000 identitas untuk setiap pelanggaran pada tahun 2010, hampir empat kali lipat dari pencurian data yang disebabkan oleh faktor-faktor lain.
Ancaman di Jejaring Sosial
Popularitas jejaring sosial terus meningkat dan popularitas ini pun telah menarik malware dalam jumlah besar. Salah satu dari teknik serangan utama yang digunakan dalam situs jejaring sosial melibatkan penggunaan URL yang dipendekkan. Dalam keadaan normal, URL yang disingkat ini digunakan untuk mengirim link secara efisien di dalam e-mail atau pada halaman web ke halaman web lain.
Tahun lalu, penyerang mem-posting jutaan link pendek ini ke situs jejaring sosial untuk mengelabui korban agar terkena serangan phishing dan malware sehingga meningkatkan tingkat keberhasilan infeksi secara drastis. Laporan ini mengungkapkan bahwa penyerang sangat memanfaatkan kemampuan news-feed yang disediakan oleh situs jejaring sosial terkenal untuk mengirimkan serangan secara massal.
Dalam skenario seperti ini, penyerang masuk ke sebuah akun jejaring sosial yang dibajak dan mem-posting sebuah link pendek yang mengarahkan ke sebuah website berbahaya di status korban. Situs jejaring sosial tersebut lalu secara otomatis mengirimkan link itu ke news feed teman-teman korban sehingga menyebarkan link tersebut ke ratusan atau ribuan calon korban dalam hitungan menit.
Berdasarkan pengamatan Symantec pada tahun 2010, 65 persen dari link-link berbahaya di news feed menggunakan pemendek URL. Dari jumlah tersebut, 73 persen diklik sebanyak 11 kali atau lebih dan 33 persen mendapatkan antara 11 hingga 50 klik.
Pada tahun 2010, toolkit serangan, program software yang dapat digunakan baik oleh pemula maupun ahli yang ingin memfasilitasi peluncuran serangan secara luas pada jaringan komputer, semakin luas digunakan. Kit ini semakin menargetkan kerentanan di sistem Java yang terkenal, yang mencapai 17 persen dari seluruh kerentanan yang memengaruhi plug-in browser pada 2010.
Sebagai sebuah teknologi multi platform yang lintas-browser, Java merupakan target yang menarik bagi penyerang. Toolkit Phoenix bertanggung jawab untuk sebagian besar aktivitas serangan pada tahun 2010. Kit ini, serta banyak kit lainnya, memiliki kemampuan untuk mengeksploitasi kerentanan Java. Serangan berbasis Web urutan keenam selama periode pelaporan juga merupakan upaya untuk mengeksploitasi teknologi Java.
Jumlah serangan berbasis Web yang diukur per hari meningkat sebesar 93 persen pada tahun 2010 dibandingkan dengan tahun 2009. Karena dua pertiga dari keseluruhan aktivitas ancaman berbasis Web yang diamati oleh Symantec secara langsung dikaitkan dengan kit serangan, kit ini kemungkinan bertanggung jawab untuk sebagian besar peningkatan tersebut.

10 Tablet Must-Have Features

noreply@blogger.com (Rio) — Tue, 26 Apr 2011 13:42:00 +0000

Image by Getty Images via @daylife

By Elna Niemann
In order to help you decide on a tablet, here is a list of 10 things that a tablet must have for you to even consider buying it.

Big display: By big display I mean a display that is big enough for you and for your intended use of the tablet. If you intend to do mostly web browsing and stuff like that, a 7 inch screen would be big enough. If, however, you intend to watch video's with the family or do photo editing or play high resolution games, then a bigger screen size would perhaps suit you better. The intended mode of transport must also be taken into consideration. If you intend to carry it around in your handbag, then it must typically be smaller than your handbag. If, however, you are going to carry it around in a briefcase or its own carry case, then go as big as you like. Just remember that with increased size comes increased weight, and the heavier it is the less comfortable it will be to use for extended time periods.
Good Operating System: Can the tablet's operating system do what you want it to do? At the moment, the most proven operating systems are the iOS from Apple, and the Android 2.2 and Android 3 (or Honeycomb) from Android. Until they can successfully convince the critics, rather stay away from Windows 7 or webOS for the moment.
Lots of Applications: The availability of applications is a major must-have for any tablet. Applications extend the functionality of the device and typically provides more entertainment and productivity. Apple has a huge collection of apps available for its iPad and iPad 2, some free and others not, so you don't have any worries there. Android also has more than enough apps available, and isn't as strict as Apple when it comes to accepting new apps, meaning you could easily write your own apps and make it available to everyone else for free or at a cost.
The Right Price: This is something only you can decide on. It is important to keep in mind that you most often get what you pay for, so it is best not to go for the cheapest no-name brand made in China. That being said, the most expensive ones are also not always the best. Compare features and functionality, then bring in price.
Value for Money: This one is a follow-up on the previous point. Is it worth its price? Does its features and functions justify the price? This all depends on what you value most. If you value luxury more than practicality, be prepared to pay for it.
Two Cameras: Only if you want it. It does add value (and price) to the device. Use it for video calling, taking video's and pictures, etc. If you don't need two cameras, you can consider a cheaper tablet with just one or even no cameras. Once again, it depends on what you value.
Excellent Virtual Keyboard: Since a tablet uses a touchscreen interface, the only way for you to communicate with it and through it is by using its virtual keyboard. Therefore, it must be easy and comfortable to operate. The virtual keyboard must be very responsive without making a lot of mistakes. Test drive a few tablets' virtual keyboard to see which one is more comfortable and efficient for you.
3G connectivity: An absolute must if you live in South Africa or any country where Wi-Fi hotspots are not readily available or not in your neighbourhood. Even if you are lucky enough to have Wi-Fi hotspots close by, a tablet is meant to be a mobile companion and 3G connectivity is crucial to achieving that.
Flash Support: If you plan to use your tablet as a partial computer replacement, this is a must. Many websites today use flash, and if your tablet doesn't support it, your web browsing experience will be seriously crippled. Apple decided that Adobe's Flash is a potential security risk that it does not need, hence the iPads don't support flash. Android, on the other hand, have shown them that they actually do need it, and Android operating systems from version 2.2 onwards support flash.
Good Battery Life: Once again, a tablet is meant to be a mobile companion. You therefore don't want to be limited in that mobility with a power cable every few hours. Depending on what you intend to use your tablet for, you should consider what kind of battery life you require and can settle for. The longest is obviously the best, but comes at an increased price. Whatever you decide to do with your tablet, you must be able to get at least a few hours of work out of it before it needs recharging. Remember that web browsing uses more battery power than just running applications. Most tablets have separate battery life specifications for web connected and non-connected activities.

So that is my list of must-have features for a tablet. I hope it proves to be helpful if you are looking at buying a tablet.

Mobile Starting to Dominate

noreply@blogger.com (Rio) — Tue, 26 Apr 2011 13:36:00 +0000

By Alexander Speirs
The development of the mobile ecosystem per se has been some time in coming but with the evolution of Mobile as we now see it in 2011, the stage is truly set. There is little doubt that Mobile is to become the most dominant medium that marketers and consumers have yet to experience and its impact will be revolutionary. Marketers are connecting with the opportunities that Mobile presents and engaging with the concept that Mobile is more than just a strategy. Mobile is a channel. Its audience is growing and so are their demands for better more creative advertising and marketing.

Advertisers who want to stay on top of their game must redefine their approach and adapt to the needs of the 'new' consumer. Retailers need to look more at location-based mobile tactics to drive that all important foot traffic into their stores. Today's consumers shop smarter and a lot of their purchasing decisions are made on mobile. Internet searching for deals, local promotions, price comparisons are all part of the fun as well as making shopping easier and more prudent. Many will use Facebook to find out what their peer reviews and ratings are showing and many will revisit later to post their own reviews thus there is that all-important word-of-mouth advertising too.
The shopping experience has been enhanced considerably by mobile and that anytime-anywhere online shopping opportunity. Thanks too, to the combination of useful applications and easy to access information. Shoppers are welcoming advertising direct to their mobiles and that ability to interact and opt-in for coupons and local deals.
Coupled with the enormous adoption of Smartphones and its amazing technology and fewer people using feature phones, there is the emerging trend of owning tablets. In fact, analysts are predicting more than 50 million tablets will be sold in 2011. Tablets have big, bold screens and offer advertisers so much more scope for their rich media online ads and videos. With 96% wireless penetration in the US, Mobile technology truly is within reach of almost every American and it is easy to see why it is becoming the most dominant medium.
With so many mobile devices around, and the introduction of more and more platforms and new devices, it is not difficult to see why mobile is impacting significantly in so many areas of our lives. If you haven't yet turned on to mobile marketing to enhance your business, don't get left behind -find out more today!

Hard Drive Performance Comparison

noreply@blogger.com (Rio) — Sat, 16 Apr 2011 14:08:00 +0000

Image via Wikipedia

By Chris Ondo
I have had many people ask me including fellow network administrators, Information Technology Consultants, College Students and Business Owners what is the difference between the Seagate ST31000528AS drive and the Seagate ST31000524AS drive?
The only real difference between these two seagate barracuda drives is read and write performance. Overall both of these drives are considered high quality and have proven to be reliable if used correctly.
I personally use and recommend Seagate Barracuda hard-drives and use them when I need reliable SATA drives. They serve their purpose well if they are used correctly in the right environment and situation.
You probably won't notice a difference in performance between the two different drives unless you are using the hard drives on a RAID array or MIRROR array and are using the hard drives to store large amounts of data where read and write performance is important such as on a file server, database server, email server, terminal server or even a web server.

Both hard drives are in the same ball park as far as price is concerned so there is no good reason to choose the slower drive unless you are using a 3.0Gb/s bus where you would not be able to take advantage of the faster hard drive - Seagate ST31000524AS anyways.
Here is a simple comparison between the two Seagate Barracuda Drives:
Seagate ST31000528AS
Series Barracuda
Interface SATA 3.0Gb/s
Capacity 1TB
RPM 7200
Cache 32MB
Average Latency 4.16ms
Form Factor 3.5 inches
VS
Seagate ST31000524AS
Series Barracuda
Interface SATA 6.0Gb/s
Capacity 1TB
RPM 7200
Cache 32MB
Average Latency 4.16ms
Form Factor 3.5 inches
As you can see above the only real difference between the two Seagate Barracuda hard drives is the Seagate ST31000528AS has a read / write speed of 3.0Gb/s while the Seagate ST31000524AS has a read / write speed of 6.0Gb/s.
Obviously I would prefer the faster hard-drive and both are high quality and reliable for small to medium sized business and if properly configured will make you happy.
When fellow network administrators or and small and medium sized businesses in and around Orlando Florida and Central Florida turn to me for technology advise and ask me which hard drive between the two models would I personally prefer and I would choose the faster drive because well it has a read / write speed double that of the Seagate ST31000528AS

A "Good" Wireless Mouse

noreply@blogger.com (Rio) — Sat, 16 Apr 2011 13:56:00 +0000

Image via Wikipedia

By Toni Li

You may have forgotten: you spend hours with mouse in hand. Choosing a quality model can gain in precision, responsiveness, and even automates common tasks. In this mouse and cat game, the competition between Logitech, Microsoft and others is fierce.
What mouse you choose? My opinion of the best mouse of the moment.
You will realize how useful it is to use a good wireless mouse when you actually tried one. Inevitably, spending 40 to almost $100
for some models seems totally surreal at first, especially when any CPU is already supplied with a basic mouse to correct basic use. If you have the opportunity, try to compare the "good" mouse to that of a "basic" mouse. Take note of these features when doing comparison: comfort for hours on end, responsiveness, sensor monitoring, ability to control the mouse on any surface, multi-speed automatic shift cursor based applications: choose a model that even mid-range radically changes our relationship to the computer. Once you take note of these good wireless mouse What is a "good" wireless mouse? These are the criteria I think qualify as a "good" mouse.
Ergonomics: manufacturers come to call upon ergonomists to relieve hand. Forms are studied, refined, optimized for ideal placement of the fingers and palm. Ask yourself. Does this mouse feel comfortable?

Laser sensor: Conventional infrared sensors should ideally be used on mouse pads. They may sometimes skip, even if moved only partially. The laser sensors do not have this problem. They follow whatever movement above the surface: plastic, glass, shelf, toilet, spaceship... Choose laser mouse.
An intelligent wheel: on the Logitech MX and VX are chosen based on need: with or without notch, for scroll a long document faster. Another alternative: eliminate the wheel in favor of a sensor field (Genius, NSW, T'nB...), like the iPod...
Resolution up to 2000 cpi (or dpi). The higher you go, the more the cursor on the screen will go quickly. Simply put: 800 dpi is sufficient for screens 19 "and under, 1200 dpi is more comfortable on the 22-inch, 1600 cpi about 24 inches (the cursor through the monitor already twice as fast as usual) and 2000 cpi, possibly on the dual-screen systems. Choose resolution based on your screen size.
Frequency up to 1000 Hz: 125 Hz normal mouse sends its position to the computer 125 times per second, ie every 8 ms. A Mouse 1000 Hz can reduce this time interval to 1 ms. On the one hand, the latency is reduced accordingly, on the other movements are naturally more accurate. Your changes of direction are taken into account earlier. Frequency is not big concern.

Branded Memory Sticks, Promotional Flash Drives, Why So Many Names for The Same Thing?

noreply@blogger.com (Rio) — Sat, 16 Apr 2011 13:48:00 +0000

Image via Wikipedia

By Alan J Grainger
If you are thinking of using promotional flash drives as part of your marketing campaign, you certainly are not alone. Promotional memory sticks are fast becoming one of the most popular forms of promotional items due to their wide range of practical applications and visible branding area. But anyone who has been searching for these items online can't help but have noticed the many different names for the same product, with titles ranging from branded memory sticks to custom flash drives and promotional USB drives. So why all the names?
Promotional memory sticks never got off to the best of starts. Before they were even thought of as promotional items, they already had something of an identity crisis going on. They've been known as memory sticks, flash pens and USB drives over the years and it just seems to be one of those items that nobody has a set name for.

Their introduction into the promotional arena just brought with it even more problems. Are they branded memory sticks? Are they promotional memory sticks? Does it even make any difference? There are many names for the branded flash drive that basically mean the same thing. Whatever you hear it being called, it doesn't change how practical and versatile branded flash drives are as a marketing product.
The concept of the promotional USB drive is a brilliant one. A small and practical item with a large branding and engraving area that is relatively cheap is a combination that is proving to be irresistible across the marketing and promotions departments of the country, and if you haven't received one as a promotional item yet, it is only a matter of time until you do.
USB drives have become an important part of business, giving staff the ability to backup important files, transfer data between home and office computers and take their information on the move if they're working on the commute.
Whatever you call your flash drives, the point remains that they make effective promotional items. As for the reason behind all the names, well it appears that no single name became popular, so we're stuck with all of the titles that have been built up over the years. Their effectiveness cannot be questioned however, and the branded flash drive is set to take over the promotional world as more and more companies realise how powerful they can be for enhancing their brand.
Alan writes articles on issues surrounding the branded flash drives industry for Branded USB Flash Drives.

Windows XP Service Pack 2 Tidak Disupport lagi oleh Microsoft

noreply@blogger.com (Rio) — Sat, 16 Apr 2011 08:35:00 +0000

Image by Getty Images via @daylife

Dalam situs resmi Microsoft dijelaskan bahwa support untuk Windows Sp2 berakhir pada tanggal 13 Juli 2010.

”Support for Windows XP with Service Pack 2 (SP2) will end on July 13, 2010. If you are running Windows XP SP2 after support ends, you will not receive security updates for Windows. To keep your Windows XP computer up-to-date download Service Pack 3 through Windows update now.”
(http://www.microsoft.com/downloads/en/details.aspx?FamilyID=049C9DBE-3B8E-4F30-8245-9E368D3CDB5A)

Seperti yang dikatakan oleh pihak microsoft bahwa tidak ada lagi update security yang disediakan bagi Windows SP2 setelah tanggal 13 Juli 2010. Beberapa dari kita mungkin baru sebagian yang mengetahuinya, namun informasi ini sangat penting mengingat di forum-forum IT sering dibicarakan banyaknya virus dan bug yang sering mengganggu sistem operasi windows sp2 bahkan sampai melumpuhkannya.

Bagi yang sudah terlanjur menginstal Windows SP2 ada baiknya mengupgradenya menjadi Windows SP3 yang masih disupport oleh pihak microsoft. Update security sangat penting melihat begitu cepatnya teknik penyerangan virus yang terus dikembangkan para Cracker iseng dan tidak bertanggungjawab.

Bagi yang akan membeli komputer & notebook baru yang ingin menggunakan OS Windows sebaiknya menginstal versi SP3, Vista dan atau Windows 7, walaupun virus terus berkembang paling tidak tingkat kerusakan OS bisa diminimalisasi dengan terus mengupdate securitynya.

Top Tips for Purchasing and Using a Wireless Print Server

noreply@blogger.com (Rio) — Wed, 13 Apr 2011 03:25:00 +0000

By David S Phillips

If you have a standard USB or serial port printer, then you will be pleased to know that it is extremely easy to convert it to a fully-functional wireless printer that can operate on a Wi-Fi network. Thanks to a wireless print server we are able to share one or more printers conveniently between a network of computers. Wireless print servers are usually available in 802.11g and 802.11b varieties. You should identify which wireless standard your network consists of, and purchase a print server that is compatible with it. Most networks make use of the 802.11g standard, and yours most likely will.
You can connect your printer to the wireless print server via a network cable, USB 1.1, USB 2.0 or via a serial connection. Most print servers allow for 2 printers to be connected to them via any one of the previous listed technologies. The print server will then share your printer across the network, much like a wireless router shares an internet connection to many individual workstations.

Once the printer is shared, you will be able to access it on a specific computer by clicking the "Devices and Printers" option in the Windows Control Panel (Windows 7). Proceed by clicking on "File" and then "Add a printer", then "Add a network, wireless or Bluetooth printer". When the name of your printer appears click it and then click "Next" and "Finish". You can print a test page in order to test the connection between your printer and PC.
Print servers also come with other benefits, for example you will not be required to keep a computer turned on in order to print. One computer won't manage all of the print jobs either, which means you won't be wasting performance. Your printer will be able to conveniently be located anywhere within the wireless network range. Administrators will also be able to change computer names and other settings without having to re-configure settings for network printing.
There are many Wi-Fi printer servers on the market, although a very popular one is the Cisco-Linksys WPS54GU2 Wireless-G Printer Server. It is claimed to be the best solution for converting a non-wireless printer to one that can work via Wi-Fi. It allows you to connect up to 2 USB or parallel printers and makes use of 802.11g Wi-Fi technology. It even comes with an easy setup wizard to guide you through the installation process, so someone with no computer experience can set it up.

The Difference Between Inkjet and Laser

noreply@blogger.com (Rio) — Wed, 13 Apr 2011 03:24:00 +0000

By Paul Natonason

When you are in a quandary as to what kind of printer to buy for your computer printing needs, the first thing you should think about are features and functions between the inkjet printer and laser printer. Another factor is will the printer be used for home purposes or business type projects, evaluating what each can do and for what purpose is what this article is all about, let's get started.
Technology is moving at a very rapid pace and what use to be the "best" printer is very quickly becoming obsolete and it seems like every time you look another new unite comes along with more improvements and better features. This does not make our buying decisions very easy. One thing to always consider before buying is the end result cost or long term cost associated with each type of printer I will get into this a little more in depth in the following paragraphs and also give you a base understanding of the differences between the inkjet and laser printer. Let's start with what you should ask yourself before making a buying decision:
1. How many pages per month will you be printing? - You can easily find an inkjet printer for right about $100.00 dollars by all the major manufacturers, however these printers are not made for high volume printing, they are made more for occasional use such as 5-10 pages per day. On the lower end a laser printer can cost about $300.00 however they are made for more demanding type jobs without having many issues, If your printing about 50-150 pages per day you should be fine with this type of laser printer.

2. Do you need color or monochrome printing? - You will be hard pressed to find an inkjet that only prints in black and white; those little cartridges can get pretty expensive to replace. On the other hand you can easily find monochrome laser printers that can print up to 5,000 - 10,000 pages without needing more toner.
3. What kind of printing do you need? - I know you thought this article was going to be one sided towards the laser printer however this is where the good old inkjet shines. When photo quality is concerned you can't go wrong with the inkjet, it puts out exceptional color printing especially when they are pictures. The laser printer can do a very good job at this however when compared the inkjet the quality is not as good.
4. Maintenance? - OK remember I told you to always keep the long term cost in mind this is where the rubber hits the road. If you run across any issues with your $100.00 inkjet printer you will probably just go out and buy a new one. However a laser printer can in most cases be serviced or fixed rather inexpensively this in my opinion will cost less in the long run, how you might ask, if you purchase a new printer you have a learning curve on using the new model. Also you will have to install new software to run your new printer. Time is money, if you have to pay someone to install everything and train your people or yourself on how to use your new inkjet this comes off the bottom line of the cost.
5. Cost per page? - I touched on this point a little earlier, however it deserves repeating, almost any way you slice it your cost per page is less with the laser printer. This is because an inkjet printer cartridge holds much less than a toner cartridge does for a laser printer. When you look at the long term costs of even a penny or two it's quite substantial.
OK folks I've given you a few basic things to consider when buying a printer and a little comparison between the inkjet and laser printers, all and all you will be better served by a laser printer however if photo quality is your thing (graphic designers and the like) you will probably be happy paying a little more per page because of the quality you will be getting.

As Cyberwars Increase, IT Professionals Need To Be More Prepared With The Highest Skills

noreply@blogger.com (Rio) — Wed, 13 Apr 2011 03:19:00 +0000

By Apple Tan

Cyberwars are now occurring between nations and governments must be well prepared as it might just be the beginning. IT staffs of public and government organizations should actively participate in industry-leading Information Security platforms such as EC-Council's hacker conference in order to have the highest knowledge and skills to defend their organization's information security.
South Korea government made a press statement recently stating that their GPS signals were jammed in some parts of South Korea and believes North Korea was behind the cyber-attack. Some fear the attacks could even be the first stage of an all-out cyberwar as experts speculated possible future provocations by the North against South Korean power, traffic, communication, military and other state infrastructure. The North Korea has been training up a hacker squad since 1986.
The French National IT Systems Security Agency has also made announcement regarding the recent attack on French government computers, saying they were targeted by cyber spies.

France's security agency's director-general, Patrick Pailloux said at a news conference, around 150 IT staff spent the weekend on a massive clean-up operation to undo the effects of the attack on computers at the French Ministry of Economy, Finances, and Industry. The attack compromised around 150 of the ministry's 170,000 PCs.
The attack started with a chain of email messages with malware-laden attachments that exploited then-unknown or unprotected flaws in the software running on the ministry's PCs. The messages were addressed to ministry staff of all levels, and alleged to come from colleagues or regular correspondents elsewhere, while the attachments appeared to relate to their work, Pailloux said.
Trojan horse software was installed on the PCs once the attachments were opened. Under the control of the unidentified attackers, that software was then used to compromise other PCs, to send data out of the ministry hidden in other Internet traffic, and finally to cover up its activities.
Pailloux said the attackers had gained access to mailboxes and servers over the course of several weeks. It took the agency a week to figure out what the Trojan horse was doing, and just how far it had spread.
Pailloux declined to comment on who might be behind the attack, although he did acknowledge that it resembled an attack on Canadian government IT systems last month. That attack was initially blamed on the Chinese, an accusation the Chinese swiftly denied.
It is believed that Cybercriminals who were operating in China hacked the computers of several Canadian government departments recently and may have accessed critical financial and weapons information.
Charles Burton, a professor of Chinese politics at Brock University in Ontario, told CBC News, "Canada has access to secrets that are shared with other Western industrial countries, with regard to sophisticated weaponry. And the Chinese government would have strong interest in getting hold of technologies,"
It's possible, Burton added, that the hackers were also going after sensitive data about Canada's oil and gas resources. Chinese officials have denied any involvement in the attacks.
IT professionals can increase their knowledge by participating in hacker conference that provides a platform to assess the best practices in acquiring, implementing, managing and measuring information security. Hacker Halted is a premier IT security conference for Information security professionals all over the world who are looking to improve their knowledge on any aspects of Information Security. At this hacker conference, they will be able to participate in discussion and information security conference, and will have the unique opportunity to assess and be better informed about the latest technologies and the best solutions that are being showcased all in one place. Unlike any other IT security conference, Hacker Halted covers real information security experience and solutions that fit into global security attacks scenarios, and help you deal with increasing threats, compliance and even regulatory issues.

What Is Cloud Computing?

noreply@blogger.com (Rio) — Wed, 13 Apr 2011 03:14:00 +0000

By Robyn Leanne Smith

There are probably more definitions of cloud computing than there are cloud providers. The term has been so ambiguous for the last few years that there isn't, and probably never will be, a general consensus on 'What is Cloud Computing?'
One definition of cloud computing is the process of renting data capacity from a data center and accessing the data over the internet. The operating system and software will be provided by and maintained by the staff at the data center who will usually be experts in cloud computing. You can contact your cloud provider to quickly have your data capacity increased or decreased as your traffic warrants - cloud computing is noted for its scalability. The service is mostly rented but rather than rent an individual server, you only pay for the capacity of data you use.
However, while this is correct on a basic level, cloud computing comprises of several elements, from structure to services, which contribute to its definition. The cloud is made up of several layers, all of which can ultimately be accessed by users connected to it. These are:
Client
The Client layer of cloud computing is the hardware and software that receives the application delivery and presents it to cloud users. There are selected operating systems, computers, browsers and mobile devices that are designed specifically to manage cloud delivery. Examples include the iPhone (mobile device), Android (OS), netbooks (computers) and Google Chrome (browser).

Application/Software as a Service (SaaS)
Software as a Service (SaaS) is arguably the most utilised layer of cloud computing and is the delivery of software as a service over the internet via a web browser. This means that users never have to install software onto their own computer and can access their programs anywhere. The cloud provider is responsible for the management of the software, including installation, updates and removal.
Infrastructure/Infrastructure as a Service (IaaS)
The Infrastructure as a Service (IaaS) layer allows users to purchase/rent a cloud infrastructure as a service. This means the components of a virtualized platform/infrastructure, the software, servers and network equipment etc, can be outsourced rather physically purchased. As with most elements of cloud computing, this is mainly billed on a usage basis, meaning users will pay for the services they use rather than the infrastructure as a whole.
Platform/Platform as a Service (PaaS)
The Platform as a Service (PaaS) layer delivers a cloud computing platform in its entirety. It consists of SaaS as well as IaaS, meaning users can utilise both services in one package without having to purchase any additional application software or hardware.
Server
The server layer of the cloud is made up of the hardware and software needed to run cloud services. This includes the server's operating system, selected software, processors and memory, among other things.
It is important to remember that when someone mentions cloud computing, they could be talking about any combination of these 'layers'. Those of you thinking about moving your business into the cloud - its vital that you understand what exactly this means, what elements of the cloud pertain to you and how much change is really involved in the process.

How Cloud Computing And Mobile Tech Is Changing Our Daily Lives

noreply@blogger.com (Rio) — Wed, 13 Apr 2011 03:12:00 +0000

By Carolyn Clayton
In today's world our computers have become an inseparable part of our daily lives. We take them with us everywhere we go in one form or another. This constant availability to technology has created an environment where we are always connected to the important data of our lives.
One of the major advantages of having technology at our finger-tips is that we always have access to our favorite movies, photos, music and more. When traveling, we never have to be without important documents, out of touch with friends and family members, or be without the latest news and current events. Of course, with all this connectivity we also need tools and services to keep everything straight and easy to use. One of the most important developments in that regard has been the "cloud".
Cloud computing is a term that is used to refer to the storage of information on internet based servers rather than local storage devices. A person can access data from any connected device that has been given permission to do so and, if needed, has the right software installed. Some services and functions require you to install specialized programs, while others simply are used through portals accessible from your internet browser.

Some of the more popular cloud-based services are photo and music sharing sites. These services allow you to back up your photos and share them with others, with only a few clicks of the mouse. It is no longer necessary to "zip" photo files, use complicated compression formats, or wait for pictures to be printed out and mailed to loved ones. Uploading files and giving permissions to your friends and family is an easy task that will allow them to view your latest pictures from their systems.
Another very active component of cloud computing is the virtual office. Services such as Google apps, allow you to keep all of your office suite applications available anytime you need them, from any connected device. You can do just about anything with one of these services that you could do with desktop-based software, such as write documents, work with spreadsheets and even create slide show presentations.
These systems are also tied to social networking and the cyber-life trend that is becoming popular. These social networking services take advantage of the power of the cloud to make sharing, connecting and experiencing information much easier than ever before.
Adding a computing system that is specifically designed to be versatile and flexibility is the logical evolution of the hyper-connected, everywhere tech life that we have developed in our modern society. These are only the first stages of the ever expanding technological demands that are being addressed by developers and programmers. As new demands are placed on systems, they will continue to evolve to meet the needs of consumers.

Cloud Biz Computing - So That's What It Is

noreply@blogger.com (Rio) — Wed, 13 Apr 2011 03:10:00 +0000

By Sandra Tiffany

All the discussion about "cloud biz computing" is leaving many people in a fog of confusion. They've heard the term, they've seen it on TV and computing magazine advertisements, think they know what it means but they're still not sure what it's all about.
In truth, most users of the internet are already quite familiar with cloud computing, but are not aware of the various applications that are already based on cloud technology. Anyone who has used web-based email, scheduling services, online file storage or social book marking sites has already entered the cloud.
The technology has also moved into the warehouse for inventory control and shipping processing. This type of application is perfect for multi-chain retail stores and franchises.
It's likely that cloud computing will move into other areas as well. Modern medical facilities make use of tablets to gather information. When the records are kept in the "cloud" all the staff will have instant access to the data and will work together in providing coordinated treatment.
The legal profession requires the use of many types of documents. The law firms can scan legal documents, store then in the "cloud" and access them via the internet. The "cloud" is the perfect environment to store the legal documents because its sophisticated data retrieval techniques make finding documents easy. All parties involved in legal and contractual proceedings have access to all the cases records via the cloud. The use of tablets will play a big role in the legal field.

The client in the cloud computing environment doesn't need special hardware and that's a real plus for small businesses. Small business employees may use a PC, Mac, tablet or an old PC, but cloud will not care. Ironically, sometimes computers in the same office do not have compatible software, files or data.
Ideally, a cloud user should have the same experience whether he is using his desktop personal computer or his mobile phone or tablet. Now, data is transmitted to a cloud application where it is stored or retrieved when necessary.
Providers of cloud services upgrade their servers on a frequent basis. Businesses can take advantage of the "cloud" data centers and their massive scalable computing power. For instance, a business may have a project that requires huge number crunching and lots of computing power and with the "cloud" it's there at their finger tips. A company has access to computing power as well as data storage and easy access retrieval. No need for large disk farms to store all the data.
Another factor that is taken care of by the "cloud" is the operating system, since cloud-based applications will be platform independent. So irrespective of hardware, software or internal operating systems, the "cloud" will have the answers.
The importance of cloud computing has not been underestimated by major corporations. After conducting studies into the IT staffing patterns and budgets of small businesses, IBM announced a major initiative to enter the cloud computing market. Of course, Google, an already established master of the virtual domain will be a big player in cloud computing.
Microsoft will also be a contender with its strong reputation as a provider of software to small businesses. The most likely scenario is for IBM to garner the large corporate market, Microsoft to cover the small to medium business market plus educational institutions and Google to maintain a strong presence with consumers and the self-employed.
So now that the fog of confusion about "cloud biz computing" advertising has been cleared away, nothing will surprise you.

How to Make Windows 7 a Lot Faster

noreply@blogger.com (Rio) — Wed, 13 Apr 2011 03:08:00 +0000

By Richie Setiawan
One of the operating systems that a lot of users prefer to use worldwide is often the Windows OS from the Microsoft Corporation. Besides practical to use, Windows also sports an interesting GUI. In fact, with some high end VGA cards, the GUI can spoil users' eyes even more. However, the bad news is that most Windows versions - including Windows 7 - often have a common problem over time. They become slow and annoying to use. But fortunately, there are ways users can approach to make their Windows 7 faster. These approaches also apply to other versions of Windows.
First of all, users need to check how much space is left free on their hard drive. If they do not seem to have enough free space, it is time to remove some installed programs. This can be done by clicking Start - Control Panel - Uninstall a program. Another option is to click Start and type appwiz.cpl.

Cleaning up the hard drive is also a good thing to do. To carry it out, users simply need to click on the Start button and then navigate to All Programs, Accessories, System Tools and click Disk Cleanup. This will bring out a small window that checks for any possible files to delete and it will then display all the files in a list.
Making changes to what services or programs Windows runs during startup is also another good idea to make Windows 7 faster. The System Configuration utility is what users will need in this case. They can launch it by clicking Start followed by typing msconfig. Here, users will first have to check the Startup section to see any programs that may turn out unnecessary to run during startup meaning they are safe to be deactivated. Then, users will also have to take a look at the Services section to find out what services they can deactivate without damaging their system.
Last but not least, another effective method to make PC run faster is by cleaning the Windows registry. To do this, users can take advantage of a third party registry cleaner. Fortunately, users have loads of options to choose from when it comes to registry cleaners these days and most of them are often quite handy in cleaning the registry. The reason why users should clean the registry to make their system faster is because the registry gets messed up over time due to installation and removal of applications. Sometimes, removing applications does not remove the entries they have made in the registry. As a result, there are more items in it Windows has to check and this slows down the system.

Questions Before Buying a Tablet

noreply@blogger.com (Rio) — Thu, 17 Mar 2011 07:17:00 +0000

By E Lewis
Tablets can be a great addition to collection of useful technological devices. They are lightweight, compact, can do many computer related basic tasks and can be bought for much less than a notebook. The only thing that poses a problem is determining the one that first your needs and your budget. The current tablet market has been inundated with tons of options.
In most cases, the devices usually fall into three categories: entertainment, enthusiast and professional use. Before going out and buying the most expensive one, you need to first assess the category that you fit into. If you fit into more than to categories, don't worry, we will address that.

The second thing you need to closely assess before buying your tablet is your budget. Tablets range in price from around $300 to over $1000 and the products within this range are numerous and can be overwhelming when choosing from them. If you are using this for professional purposes then your budget can be towards the more expensive end of the spectrum. If this is strictly for entertainment, then you choosing a product that provides your basic needs, but won't destroy your bank for the next 6 months.
The next step is choosing features and these are going to play an important part in the cost of the unit. The most expensive elements that determine the price of a tablet is the size of the touch screen and the processor inside. Some tablets have screens that are 7-inches in size, while others have larger 10.1-inch screens. As for processors, some tablets have the more basic processor developed for tablets, which can perform less processor intensive tasks. The more expensive tablets have either the Intel Atom processors; found in netbooks or in some cases the very powerful Intel i5 dual core processors, which are often found in upper tier notebook computers.
The other features that may be important to you are hard drive space, external USB ports and operating system. Aside from Apple using their own OS, most tablets come with either the Android software or Windows 7. If you are buying from a PC brand, than you need to assess the operating system that fits your needs properly. The Android system is very customizable and users can find thousands of applications online. The Windows 7 operating system is powerful and on a tablet has some really great features, such as handwriting recognition. This application can determine almost any hand written note and decipher it into a different language. Very useful for individuals that like to travel often.
E.Lewis is an avid technology junkie and his current obsession is the tablet and specifically the Samsung Tablet and the Current Windows 7 Tablets.

The Principles of Ethernet Cable Wiring

noreply@blogger.com (Rio) — Thu, 17 Mar 2011 07:13:00 +0000

By Richard P Steadman
Ethernet cable wiring, or Cat-5 wiring is a cable employed in the networking and telephony fields. It is familiar to anyone who has messed around with computer networks, or even tried to bridge a computer to the internet. The main benefit of this kind of cable lies in the fact that it can carry up to 100 MB of data per second, which is ten times that of its predecessor. Ethernet cable wiring comes in several different sizes including cat5 or category 5, cat6 and cat5e.

The cable is made up of 4 entwined cables of orange, blue, brown and green. These are wrapped around a twin cable of the same color, but with white stripes running through it. These pairs are then insulated from each other. While the outer coverage of the Ethernet cable wiring is important to what goes on inside it, it exists only to protect the innards of the cable, it does come in various colors, so you may decide what goes best with the color scheme of the room your network will be in.
The 4 colors of the interior cables represent different types of signal, which in turn means that they carry different types of data. These 4 colors must not blend throughout the length of the cable, as this can lead to signal interference and mixing, which in turn leads to data being dropped and the connection being disrupted.
When carrying out Ethernet cable wiring on your own, therefore, it is wise to follow this rule, recommended by experts: do not cut more than a half-inch at the end where you will attach a jack, as this will lead to the signal inside the cable being mixed, and this will lead to the aforementioned frustrating data errors.
The distinctive jack at the end of these cables is designated an "RJ-45" jack, and it is designed to interact with any machine that has a similarly shaped port inside it. This jack is what enables data to flow out of the cable and into the machine, or vice versa. As a result, you can attach the jack to the cable you have cut yourself, but make sure that you wire it tightly and that you do not end up confusing the internal wiring and therefore causing a signal error at the machine's end. If in doubt, you can simply swing by your local hardware store and pick up a pre-cut loop of Ethernet cable wiring with jacks already attached.
One can build this loop as large as possible, and this will not affect the quality of the signal within. In order to cut the wire to size, remember that in order to use this kind of wiring effectively, the inner cables' insulation is paramount. Therefore remember that a cut of? an inch is more than enough for you to be able to carry out the attachment of the jack and to protect the innards of your cable.
Ethernet cable wiring is not an design, and indeed anyone with a minimal know-how can do it, but do it wrong and frustration is going to be an inevitable result.

Fast VPN Service - Company Challenges

noreply@blogger.com (Rio) — Thu, 17 Mar 2011 07:11:00 +0000

By Nancy Joan Harris
The issue is essentially that there is an old system of distribution that accounted for geographical territories. These are the challenges that music services on the web contend with every day. Fifty year old stipulations about the recording industry have forced licensees of these intellectual properties to limit the offering to select regions. And that's where these VPN service firms are coming into play.
Granted, it's just one way that the fast VPN service is being employed. But let's take a look at what this actually is for a moment. VPN stands for virtual private network, and it basically means that you can log into the network, and then log out through there. What does this do? Well, it can give you another IP address from which to surf the web by. Okay, so now we need to back up a minute, because we've mentioned IPs three times now, and haven't explained what all that is really.

The best and fastest way to really come to terms with what an IP address conceptually is, is to think of a phone number. Basically, it is a phone number, and there's a sort of tree diagram of a hierarchy going on with the kinds of phone numbers that are distributed about the web. Basically, what happens is that internet service providers have their original stack of IP's, and then from there, they sell their own IPs to customers that want to access the internet through them. And based on particular IPs, these music service providers on the web can tell from what country you're accessing their website from. And so, it's readily apparent how a VPN service could easily come into play then.
Remember what a fast VPN service does; it basically gives you access to the network; thus the term, "virtual private network." You've got switches and routers and such, and what that means is that, eventually, if you get back out to the web, through this VPN, you can get to websites, and these websites will see the VPN services IP address instead of your actual IP address from your ISP or internet service provider. This is what's referring to as setting up an anonymous surfing situation.
Now, there are other ways to set up anonymous surfing environments, without the use of a VPN service, but that usually involves employing some sort of IP address blocker, at which point, a scanner from a web server will see no IP address at all, and sometimes, that's just as bad or even worse than logging in from a disallowed country.
Use the best VPN service possible for you security and anonymity needs.
Hope you enjoyed the article!

3 Simple Strategies You Can Use To Search For an Email Address

noreply@blogger.com (Rio) — Mon, 07 Mar 2011 13:02:00 +0000

By Jamie Rhodes
Anyone that has lost contact with a good friend or family really wants to know how to search for an email address because they know that most people have an email address and if they can find it they can get in contact with who they have lost contact with. The email is definitely one of the easiest and quickest ways to interact and communicate with anyone but finding out the email of a person can be a huge challenge. Luckily there are a number of strategies you can implement in order to find the email id you're interested in finding.

Probably the first thing that comes to mind when someone is searching for a certain email is using the one of the popular search engines out there like Bing or Google. To implement this strategy all you have to do is type in the name you want to learn more about inside the search engine box.

You should get a number of different results listed once you perform the search and all you will need to do is go through the results and find the email you are looking. This method can work but it will require a lot of patience on your part and it can sometimes produce irrelevant results.

Another strategy you can use to find out the email of any person is to utilize email directories. All email addresses of people are stored in these directories. Simply put the name of the person you're interested in, just like if you were using one of the search engines, and then the email directory will give you the results for that person if they have an email listed. You should know that this strategy will often turn up out dated information and could turn out to be a dead-end, but it's worth a try.

Finally, the last strategy you can implement to successfully search for an email address is use a service known as an email address lookup. This service is very reliable and the information you receive from a service like this is never out dated. The best part about using a service like this is that it might also give you other related information like the person of interest's phone number or even their address.

There are a number of other strategies you could use to search for an email address but these 3 search methods are three of the best and gives you the best chance to find what you're looking for.

How To Investigate a Hacked Email Account

noreply@blogger.com (Rio) — Mon, 07 Mar 2011 12:57:00 +0000

By Ed Opperman
It has become a very common problem for a persons email service to be hacked so that another person has access to your email account. In most cases this is done by an email spammer to send out spam emails. This way the spam is traced back to you and not to them and they can shield themselves from prosecution. These email spammers will usually hack into your email account by tricking you into revealing your pass words to them through the use of phishing or trojan emails. But there is another kind of hacked email account that can be far more invasive of your privacy. This kind of case involves a person that is in your life and wants to spy on you by reading all your private emails. It could be an current or ex spouse, an employee or a relative. But it is a person that wants to violate your privacy and read all of your confidential email correspondence.

This kind of email hacker is far more dangerous as they have a personal interest in invading your privacy and the information they obtain can be used against you personally.

Dangers of an Email Hacker:
- They can know who you're communicating with.
- They can follow you
- They can learn all your secrets Signs of a Hacked Email Account:
- Emails are marked read before you read them.
- Emails are deleted before you read them.
- People seem to know information they could only know from reading your mail.

Solutions:
If you do an online search about dealing with a hacked email account most of the advice you'll encounter will center around changing passwords and reporting the offense to your ISP. This may be sound advice if you are dealing with a spammer but if you are dealing with the stalker type mentioned above you'll want to protect yourself from this potentially dangerous person.
