Now we move on from the previous page ..!!!

Step 12 - Choose your region and language

Step 13 - Type in your name and organization

Step 14. Enter your product key

Step 15 - Name the computer, and enter an Administrator password. Don't forget to write down your Administrator password

Step 16 - Enter the correct date, time and choose your time zone

Step 17 - For the network setting choose typical and press next.

Step 18 - Choose workgroup or domain name. If you are not a member of a domain then leave the default settings and press next. Windows will restart again and adjust the display.

Step 19 - Finally Windows will start and present you with a Welcome screen. Click next to continue.

Step 20 - Choose 'help protect my PC by turning on automatic updates now' and press next.

Step 21 - Will this computer connect to the internet directly, or through a network? If you are connected to a router or LAN then choose: 'Yes, this computer will connect through a local area network or home network'. If you have dial up modem choose: 'No, this computer will connect directly to the internet'. Then click Next

Step 22 - Ready to activate Windows? Choose yes if you wish to active Windows over the internet now. Choose no if you want to activate Windows at a later stage.

Step 23 - Add users that will sign on to this computer and click next.

Step 24 - You will get a Thank you screen to confirm setup is complete. Click finish.

Step 25. Log in, to your PC for the first time.

Step 26 - You now need to check the device manager to confirm that all the drivers has been loaded or if there are any conflicts. From the start menu select Start -> Settings -> Control Panel. Click on the System icon and then from the System Properties window select the Hardware tab, then click on Device Manager

If there are any yellow exclamation mark "!" next to any of the listed device, it means that no drivers or incorrect drivers has been loaded for that device. In our case we have a Video Controller (VGA card) which has no drivers installed.

Your hardware should come with manufacturer supplied drivers. You need to install these drivers using the automatic setup program provided by the manufacturer or you need to manually install these drivers. If you do not have the drivers, check the manufacturers website to download them.

To install a driver manually use the following procedure:

(a) From the device manager double click on the device containing the exclamation mark.

(b) This would open a device properties window.

(c) Click on the Driver tab.

(d) Click Update Driver button. The Wizard for updating device driver pops up as shown below:

You now get two options. The first option provides an automatic search for the required driver. The second option allows you to specify the location of the driver. If you don't know the location of the driver choose the automatic search which would find the required driver from the manufacturer supplied CD or Floppy disk. Windows would install the required driver and may ask you to restart the system for the changes to take affect. Use this procedure to install drivers for all the devices that contain an exclamation mark. Windows is completely setup when there are no more exclamation marks in the device manager.

Thank you for see my blog ..

we'll see you again with another topic

how to Install Windows XP Part 2

2011-07-05T00:16:00.000+07:00

Now we move on from the previous page ..!!!

Step 8 - This step is very important. Here we will create the partition where Windows will be installed. If you have a brand new unformatted drive you will get a screen similar to below. In our case the drive size is 8190MB. We can choose to install Windows in this drive without creating a partition, hence use the entire size of the drive. If you wish to do this you can just press enter and Windows will automatically partition and format the drive as one large drive.

However for this demonstration I will create two partition. The first partition will be 6000MB (C: drive) and second partition would be 2180MB (E: drive). By creating two partition we can have one which stores Windows and Applications and the other which stores our data. So in the future if anything goes wrong with our Windows install such as virus or spyware we can re-install Windows on C: drive and our data on E: drive will not be touched. Please note you can choose whatever size partition your like. For example if you have 500GB hard drive you can have two partition of 250GB each.

Press C to create a partition.

Windows will show the total size of the hard drive and ask you how much you want to allocate for the partition you are about to create. I will choose 6000MB. You will then get the screen below. Notice it shows C: Partition 1 followed by the size 6000 MB. This indicates the partition has been created. We still have an unpartitioned space of 2189MB. Next highlight the unpartitioned space by pressing down the arrow key. Then press C to create another partition. You will see the total space available for the new partition. Just choose all the space left over, in our case 2180MB.

Step 9 - Now you will see both partition listed. Partition 1 (C: Drive) 6000MB and Partition 2 (E: Drive) 2180MB. You will also have 8MB of unpartitioned space. Don't worry about that. Just leave it how its is. Windows normally has some unpartitioned space. You might wonder what happened to D: drive. Windows has automatically allocated D: drive to CD/DVD-ROM.

Select Partition 1 (C: Drive) and press Enter

Step 10 - Choose format the partition using NTFS file system.This is the recommended file system. If the hard drive has been formatted before then you can choose quick NTFS format. We chose NTFS because it offers many security features, supports larger drive size, and bigger size files

Windows will now start formatting drive C: and start copying setup files as shown on the two images below :

Step 11 - After the setup has completed copying the files the computer will restart. Leave the XP CD in the drive but this time DO NOT press any key when the message "Press any key to boot from CD" is displayed. In few seconds setup will continue. Windows XP Setup wizard will guide you through the setup process of gathering information about your computer

After we discussed about how to assemble computers we now try to install windows xp operating system

This procedure demonstrates how to install Windows XP Professional. The procedure to install Windows XP home edition is very similar to the professional edition. Since Windows XP Pro is more advanced operating system, it will be used to demonstrate the installation procedure.

The best way install Windows XP is to do a clean install. It is not difficult to perform a clean installation. Before you perform the installation I recommend that you check Windows XP Compatibility List to ensure that your hardware is supported by XP. If your hardware is not on the compatibility list you can check your hardware manufactures website to download the drivers for Windows XP. Save all the necessary drivers onto floppy disks or CD before you start the installation.

All versions of Windows XP CD are bootable. In order to boot from CD/DVD-ROM you need to set the boot sequence. Look for the boot sequence under your BIOS setup and make sure that the first boot device is set to CD/DVD-ROM. You can then perform the following steps to install Windows XP:

Step 1 - Start your PC and place your Windows XP CD in your CD/DVD-ROM drive. Your PC should automatically detect the CD and you will get a message saying "Press any key to boot from CD". Soon as computer starts booting from the CD your will get the following screen:

Step 2 - At this stage it will ask you to press F6 if you want to install a third party Raid or SCSI driver. If you are using a an IDE Hard Drive then you do not need to press F6. If you are using a SCSI or SATA Hard drive then you must press F6 otherwise Windows will not detect your Hard Drive during the installation. Please make sure you have the Raid drivers on a floppy disk. Normally the drivers are supplied on a CD which you can copy to a floppy disk ready to be installed. If you are not sure how to do this then please read your motherboard manuals for more information.

Step 3 - Press S to Specify that you want to install additional device.

Step 4 - You will be asked to insert the floppy disk with the Raid or SCSI drivers. Press enter after you have inserted the disk.

Step 5 - You will see a list of Raid drivers for your HDD. Select the correct driver for your device and press enter.

Step 6 - You will then get a Windows XP Professional Setup screen. You have the option to do a new Windows install, Repair previous install or quit. Since we are doing a new install we just press Enter to continue.

Step 7 - You will be presented with the End User Licensing Agreement. Press F8 to accept and continue

Monitor, the output is temporary, because only looked for a while just on the screen. Its function is to see the results of input or programs running.

CPU (central processing unit)

Central processing unit (CPU) is part of a computer system that perform the instructions of a computer program, and is the main element performs the function of a computer or other processing device. Central processing units execute each instruction in program order, to perform arithmetic operations, logic, and input / output from the system basis. This term has been used in the computer industry at least since the early 1960s. [1] The form, design and implementation of CPUs have changed dramatically since the early examples, but their basic operation remains the same.

Initial CPU designed specifically as part of a larger, sometimes one-of-a-kind computer. However, this method is expensive designing custom CPUs for a particular application generally has provided a way for the development of mass production of processors made for one or many purposes. The trend began in the era of standardization generally discrete transistor mainframes and minicomputers and has rapidly accelerated with the popularization of the integrated circuit (IC). IC has allowed increasingly complex CPUs to be designed and manufactured to tolerances on the order of nanometers. Both the miniaturization and standardization of CPUs have increased the presence of digital devices in modern life far beyond the limited application of specialized computing machines. Modern microprocessors appear in everything from cars to mobile phones and toys.

Keyboard

The keyboard is the most Important input unit in a data processing by computer. The keyboard works include letters, numbers, special characters as well as a medium for the user (users) to perform other commands are needed, Such as saving files and opening files. The creation of a computer keyboard typewriters from the model created and Patented by Christopher Latham in 1868, and in 1887 the company manufactured and marketed by Remington. The keyboard is used now this is kind of QWERTY, in 1973, was unveiled as a standard keyboard keyboard ISO (International Standards Organization). Number of keys on the keyboard consists of 104 keys. The keyboard Now That We Know has some kind of port, ie serial port, ps2, usb and wireless

Mouse

Mouse is one unit of input (input device). The function of this tool is to move a pointer or cursor quickly. In addition, orders can be as practical and faster than with a keyboard. Mouse began to be used optimally since the operating system has been based GUI (Graphical User Interface). electrical signals as a mouse input device is generated by a small ball inside the mouse, according to the shifting or movement. Most of the mouse consists of three buttons, two buttons which are generally only used the left button and right button. Currently the mouse is also equipped with rollers button (scroll), where is this button located in the middle. The term suppression is called by clicking the left button (Click) where the emphasis is going to function when the mouse is on a designated object, but when not on a designated object of this emphasis will be ignored. In addition there are also other terms that are called by sliding the (drag) that is pressing the left mouse button without releasing it with while being moved. This drag will cause the object to be moved or copied to other objects and other possibilities. The emphasis of the left mouse button twice quickly and regularly called double click (double click) while pressing the right mouse button once called by right-clicking (right click) Mouse consists of multiple ports is a serial mouse, mouse ps / 2, usb and wireless

Speaker

Loudspeakers (English: loud speaker or speakers) is a transducer that converts electrical signals into audio frequency (sound) by means of components that form the membrane vibrates.

In every system of sound, best sound quality depends on the determination of the speakers. The best recording, encoded into a high-quality storage devices, and played with a deck and upper-class speakers, still the result will sound ugly when associated with low quality speakers. On the speaker system is an electronic component that carries signals, store them in CDs, tapes, and DVDs, then returned again in the form of actual sounds that we can hear. In this article, I will explain how a speaker to do the process. They also discussed why the speakers are designed differently and how these differences lead to different effects on quality.

Speaker is an amazing technology that delivers a huge impact on our culture. But besides all that, the actual speaker is simply a tool that is very simple.

Printer

Printer Technology
From time to time, printer technology continues to evolve so inevitably for someone who is always associated with computers and other equipment must keep abreast of these developments. The printer is in Indonesian language means the printer (print device). The term 'printer' is now often used to refer to a print device connected to the computer. To connect the printer to the computer needed a cable that connects from the printer to the computer CPU. Currently, the brand products are frequently used printers include Epson, Hewlett Packard (HP), Canon, Lexmark and many more. To know more clearly about the function, type of printer and the workings of the printer, please read the continuation of this article.
Function printer
The printer is one of the hardware (hardware) connected to a computer and has the function to print text, images and more views from computer to paper or similar media. The term is known at a resolution of the printer is called dpi (dots per inch). The point is the large number of points in the area of 1 inch. The higher the resolution the better the resulting mold. Conversely, if the resolution is low then the printout would be bad / not good.

   Of course you already know what it is called a computer, the computer is an electronic device that consists of many different components all of which are mutually supportive working computer system.

    Today's computers is absolutely essential to be known by everyone because it is closely related to the development of computer technology in the world, as we have seen that a variety of electronic equipment are now no longer use the analog system as before but now a lot of electronic equipment are already switching to digital systems that has a function and filtur more sophisticated, with the technological developments that are so rapidly it is an obligation for us to always be dynamic in addressing these developments.

    The computer has many benefits that aim to assist people in completing the job quickly and more easily even all the work we do should be done by computer as a robot who was programmed to perform a specific job or job-there is also a robot that is controlled by remote control .

    Once you know what a computer, then it is time you should also know the components that exist on the computer. The components on the computer there are 2 internal & external components. There are 4 external components that must exist in order to operate a computer,
The first is certainly there must be a CPU because of all the control center located on the CPU, the second is due to monitor Monitor function to display all the processes performed by the CPU so that we can see the data that exist on the computer, the third is a mouse, called the mouse because it is similar to a rat ... function is to move the mouse cursor on the monitor so that we operate a computer, and the fourth is the keyboard because of all the text entered and orders can be done by pressing the button on the keyboard.

    Other external components which are supporting is a function printer for printing text or images from computer to paper, CD / DVD-Rom / RW which serves to read or write Disc CD / DVD, modem consists of GPRS modem, ADSL, or various other types of modems that function to get connected to the internet, speakers whose function is to listen to sound on the computer, and many more external components we can add ...

When you start to learn about computers, there are a lot of new words to understand. Here is a glossary of some computer words we have learned.

Emoticons are little faces that show expressions. They also tell people what mood someone is in. :-) would mean I am in a good mood. People use them when typing e-mail messages to each other or when they are in a chat room.

E-mail stands for electronic mail. It is a fast and inexpensive way to send a message to someone. Instead of having to write a letter and put it in a mailbox, you type your letter in an e-mail program and send it electronically to your destination.

CD A CD is a way to store information. Your favorite computer game might be on a CD. When you put the CD in, there are little groves that the computer can read. Then you can save your game on the CD. The next time you put that CD in you can play where you left off.

Viruses A virus is when the computer catches something that infects the files. In just a few days it can go through almost all of the files on your computer.

Game Machine Some people have a game machine. Some game machines are Nintendo, Sega, Play Station, and Jaguar. A game machine's a computer - believe it or not. The t.v. is like the computer screen or monitor. The cartridge is like the CD or floppy disk. The controllers are like the mouse, keyboard, or joystick
Modem A modem lets you take in signals and lets you send information over the phone line. That is why when you are on the internet nobody can call you and you can't call anybody unless you have two phone lines.
Hard Drive A hard drive is the brains of your computer.

URL URL stands for Uniform Resource Locater. It is the address of a site on the internet.
Cyberspace Cyberspace is the stuff behind the screen and the satellite. Cyberspace is another word for the internet.

Hyper Text Hyper text is the blue underlined words that you can click on to go to another page.
Browser A browser is something that lets you point and click on a subject and poof you're there. When you type in the address sometimes it takes longer because you might miss a letter or forget the http://. Now it is a lot easier with a browser. You need a browser to surf. Surfing is like changing the channels on the t.v.

Password Do you know what a hacker is? Oh yeah, I forget you haven't learned yet. A hacker is a bad guy on the internet. You can keep them out if you have the right security. Here are some security tips: use passwords that have more than 3 letters, don't tell anyone your password (except your mom and dad), and choose a password that is easy to remember.

Mouse A mouse is a thing that you move the cursor around with. The curser is the arrow on the screen. The mouse is a substitute for the keyboard. The mouse also has buttons like a keyboard that can do different things.
Server A server is a host computer.

Host A host is a computer that other computers have to hook up with.

Newbie A newbie is a person on the internet that is new.

Gopher A gopher is a program that searches for files.

Icons Icons are small pictures. They can be programmed to give your computer commands when you click on them.

Packet A packet is a small part of an e-mail letter as it travels through wires.

User A person that is on the internet - like you.

Satellite A device in space that receives and transmits signals.

Satellite dish A antenna on earth that receives signals that bounce back from a satellite.

Crack When your password gets broken it's cracked. Mostly hackers crack passwords to get credit card numbers or other information.

Internet History

2011-07-04T16:17:00.000+07:00

You can compare the internet to a spider and its web. The spider's web starts out small and gets bigger and bigger until you have a web. The strings that make up the web of the internet are phone lines and the spider is you and your computer! Even though the web probably will never be finished, that doesn't mean you can't go exploring or have any fun. The internet was made so you could learn, explore and have fun. Although a spider only has eight eyes, the internet has millions of eyes to keep track of things such as the Olympics, the stock market, and hockey. The internet keeps getting bigger and bigger all the time with more than 2 million people joining every month. All of this growth continues to make the internet a REALLY BIG thing.

History of the Internet

The first internet was ARPANET, it was made up of 37 computers. These computers were so large that they took up whole rooms. The reason for ARPANET was that if we went into nuclear war, and one of the lines became damaged the signals could go down another path.

After some time they made a second internet called MILNET. The reason for MILNET was that colleges and universities had taken over ARPNET to exchange and access data between schools; MILNET on the other hand was designed for military use only.

Finally they created a third internet which was called NSFNET. This portion of the internet was developed by the National Science Foundation. It had 5 supercomputers where scholars could get access to the latest technology in supercomputers. NSFNET eventually became so popular that it took over the functions of ARPNET.

By 1994 U.S. government control of the internet had been replaced by commercial internet networks or IP networks. These networks were operated by big corporations such as IBM, Sprint and Alternet. Outside the U.S.A. many other IP networks have formed making the internet world wide.

Computers are used for different things. A few of the things people use computers for are to solve math problems, write and check the spelling of their words, play games, do homework, help fly airplanes, and keep track of information. Computers have changed a lot over the past 150 years.

An early computer that helped people keep track of numbers and solve math problems is the abacus. Chinese people have used them for thousands of years. Charles Babbage made a device in 1823 that was a calculating machine. It was used to solve math problems. He developed the idea of a machine having a central processing unit, memory for storing numbers, and programs on punch cards that would run the computer.

As electricity developed, so did computers. The other major invention that helped to develop computers was the microprocessor. Ted Hoff made the first microprocessor in 1970. This was important because a lot of information could be programmed on a small chip. Computers that used to take up a whole room could then be made much smaller. When computers were really big, not many people could afford to have one. The microprocessor helped to make the size needed for a computer much smaller and more affordable.

Before there were computers, there were other ways to send information over wires. Morse code was made up by a man named Samuel F. B. Morse in 1838. Morse code uses dots and dashes. A dot is when you hold down the telegraph for a short time. A dash is when you hold down the telegraph longer. The most widely used signal is sos. Here is the way you can signal sos in Morse code. To do a "s" you do three dot's. The "o" uses three dashes. People used to have to make the signals by themselves using their hands. Modern computers have transistors that use switches that turn on and off to send signals.

Perangkat dalam Cpu ( Central Processing Unit )

2011-06-18T23:01:00.000+07:00

Central Processing Unit (CPU) merupakan komponen terpenting dari sistem computer, komponen pengolah data berdasarkan instruksi yang diberikan kepadanya. Dalam mewujudkan fungsi dan tugasnya CPU tersusun atas beberapa komponen.

Beberapa fungsi CPU seperti yang tersebut di atas dijalankan oleh bagian-bagian yang berbeda. Dalam hal ini, bagian-bagian prosesor atau CPU komputer adalah:

ALU (Arithmetic Logic Unit), yaitu bagian CPU yang dapat melakukan perthitungan terhadap data-data dalam bentuk bilangan dan membuat keputusan logis berdasarkan perhitungan tersebut.
Register, yaitu tempat atau lokasi memori khusus untuk menyimpan informasi sementara waktu.
Unit Pengatur Program, yaitu bagian yang dapat melakukan pengaturan terhadap program-program komputer.
Bus, yaitu bagian yang berfungsi untuk membawa informasi-informasi digital.
Memori Lokal, yaitu bagian penyimpanan pada CPU.

Sementara itu, untuk CPU atau prosesor yang lebih rumit dan canggih terdapat bagian yang disebut Cache Memory, yaitu bagian CPU yang dirancang untuk mempercepat akses data dari dan ke peralatan penyimpanan data luar (external data-storage device).

Pada dasarnya, fungsi dari masing-masing bagian CPU tersebut didukung dan diatur oleh sejumlah perintah software yang masuk ke dalam memori komputer (RAM). Secara sederhana, alur kerja komputer yang melibatkan fungsi CPU dapat dijelaskan sebagai berikut.

Data masuk ke dalam komputer melalui perangkat masukan, seperti keyboard, mouse, dan lain-lain.
Data mengalir menuju ke memori komputer melalui CPU melalui kabel antarmuka (interface) dan kembali ke CPU.
Data yang kembali ke CPU dari RAM diterjemahkan oleh unit pengolahan yang disebut dekoder perintah yang kemudian diteruskan pada bagian ALU untuk mengalami proses selanjutnya dan disimpan dalam register.
Data yang telah diolah dalam ALU dapat dikirim kembali ke memori atau disimpan pada register yang lain untuk penggunaan tertentu, misalnya diakses melalui perangkat keluaran.

CPU merupakan hal terpenting dalam komputer itu sendiri, sebenarnya komputer itu sendiri identik dihubungkan dengan CPU itu tersendiri, dan di dalam CPU itu sendiri terdapat bagian/komponen lainnya sebagai berikut :

1. Motherboard

Motherboard berbentuk suatu papan yang terdiri dari beberapa komponen elektronik lagi yang memiliki fungsi mereka tersendiri. Semua perangkat komputer yang penting sebagian besar diletakkan disini, seperti Processor, RAM, VGA Card, LAN Card, dsb.
Jika ingin melihat motherboard ini secara langsung dapat dilihat apabila kita sudah membuka chasing/penutup dari komputer kita.

2. Processor

Processor atau yang biasa disebut sebagai otak komputer merupakan bagian terpenting dari sebuah komputer, bentuknya memang cukup kecil tetapi bisa melakukan banyak proses secara bersamaan (multitasking), pada gambar diatas emrupakan salah satu contoh processor yang sudah ada pada jaman sekarang.

3. RAM (Random Access Memory)

Memory adalah perangkat yang berfungsi mengolah data atau intruksi. Semakin besar memori yang disediakan, semakin banyak data maupun intruksi yang dapat mengolahnya. RAM adalah sebuah perangkat yang berfungsi untuk menyimpan data. RAM bersifat sementara atau data yang tersimpan dapat dihapus.lain halnya dengan ROM.ROM mempunyai fungsi yang sama dengan RAM tetapi ROM bersifat permanen atau data yang tersimpan tidak dapat dihapus

JENIS-JENIS RAM :

SRAM (Static Random Access Memory)

RAM yang digunakan sebagai memori tambahan yang tersembunyi.

EDORAM ( Extended Data Out Dynamic Random Accses Memory )

Yaitu, RAM yang kepingannya terdiri dari 72 pin dan umumnya pada PC yang menggunakan prosesor intel Pentium 1 dan AMD ke- 5 dan ke- 6.RAM jenis ini harus dipasang pada socketnya dalam jumlah genap ( minimal terdiri dari 2 keping ).Dan memiliki Bus Speed sebesar 66 Mhz atau PC 66.

SDRAM ( Synchronous Random Acces Memory )

RAM yang kemampuan kecepatannya lebih cepat daripada EDORAM dan kepingannya terdiri dari 168 pin.PC denganprosesor intel Pentium 1, Pentium II, Pentium III, AMD ke- 5, AMD ke- 6, AMD ke- 7.Dengan memiliki Bus Speed sebesar 66 Mhz ( PC 66 Mhz ) dan PC 100 Mhz.

DDRAM ( Double Data Rate Random Acces Memory )

RAM yang hampir sama dengan SDRAM, namun memiliki kemampuan kerja yang lebih tinggi.Dengan Bus Speed sebesar 133 Mhz atau PC 133 Mhz.Umumnya digunakan pada PC dengan prosesorintel Pentium III, Pentium IV, AMD Duron, AMD Athlon.

RDRAM ( Rambus Dynamic Random Acces Memory )

RAM yang menggunakan RIMM ( Rambus In Line Memory Module ) sebagai socketnya dengan ukuran yang lebih kecil dari DIMM ( Socket yang digunakan untuk SDRAM dan DDRAM ).Dengan Bus Speed sebesar 800 Mhz.Umumnya digunakan pada PC dengan prosesor intel Pentium 1.

VGRAM ( Video Graphic Random Acces Memory )

RAM yang digunakan secara khusus pada video adapter atau video card.Yang berfungsi untuk mendukung video adapter dalam menghasilkan tampilan proses yang sedang atau yang telah berlangsung pada computer.Besarnya kapasitas VGRAM akan menentukan kualitas gambar atau tampilan yang dihasilakan oleh video adapter tersebut.

4. Hardisk

Pada gambar diatas merupakan salah satu contoh Hardisk, hardisk berisikan perangkat elektronik yang berupa lempengan dimana yang mempunyai fungsi untuk menyimpan banyak file pada komputer. Semakin besar hardisk yang kita punya, maka semakin banyak juga file yang dapat kita simpan pada komputer. Kapasitas Hardisk juga bermacam-macam, baik dari 20GB, 40GB, 80GB, bahkan sampai mencapai TerraByte.

5. Power Supply

Power Supply merupakan bagian penting juga dari sebuah komputer. Fungsinya adalah untuk memberikan supply listrik ke komponen komputer yang lainnya, sebagai contoh adalah supply listrik untuk motherboard, hardisk, CD-ROM, dll. Jika tidak memiliki Power Supply ini maka sebuah komputer tidak dapat beroperasi.

6.CD-ROM/DVD-ROM/CD-RW/DVD-RW

CD ROM mempunyai fungsi untuk meyimpan/membaca file yang ada pada CD. Ini merupakan pilihan tersendiri untuk user jika ingin memakai CD-ROM di dalam komputernya. CD ROM hanya untuk dapat membaca CD, sedangkan kalau ingin burning (copy file ke CD), kita harus memiliki CD-RW (Read/Write). Dapat dilihat pada gambar diatas contoh dari CD-ROM.

7. Kabel Data

Kabel data mempunyai fungsi penting juga yakni untuk menghubungkan 1 komponen komputer dengan komponen lainnya, sebagai contoh kabel data ini dapat menghubungkan antara motherboard dan hardisk, tujuannya adalah Hardisk kita dapat terbaca dan melewati sistem yang ada pada motherboard.

8.VGA Card

VGA Card sangat penting untuk memberikan grafis pada komputer kita, sebagai contoh adalah monitor kita, kualitas gambar yang ditampilkan di monitor sangat berpengaruh pada VGA Card kita, semakin bagus VGA Card yang kita punya, maka semakin halus dan bagus gambar yang ditampilkan di komputer.

9. LAN Card (Local Area Network)

LAN Card mempunyai fungsi sebagai penghubung antara komputer 1 dengan komputer yang lainnya, selama kita mempunyai LAN Card ini sangat memungkinkan kita dapat terhubung dengan internet (tentunya jika kita mempunyai jaringan ADSL) ataupun bisa terkoneksi dengan komputer yang lainnya (jika terhubung ke dalam HUB/Switch).

10. Kabel UTP

Kabel UTP mempunyai fungsi untuk menghubungkan komputer 1 dengan komputer lainnya, jika kita memiliki LAN Card, tapi tidak memiliki kabel UTP maka sangatlah mustahil kita dapat melakukan koneksi antara 1 komputer dengan komputer yang lainnya.

Perangkat Dasar Komputer

2011-06-18T22:29:00.000+07:00

Hampir setiap hari kita berada di depan komputer, mengetik, menggambar, bermain game dan lain-lain. tapi pernahkah kita tau peralatan apa saja yang membentuk komputer sehingga bisa sehebat itu. berikut penulis coba menjelaskan sedikit apa saja sih peralatan yang membentuk sebuah komputer

Monitor-LCD

Monitor merupakan salah satu jenis output device yang sangat populer dalam sistem komputer. Secara fisik, monitor mempunyai bentuk seperti halnya layar televisi dan fungsinya untuk menampilkan data dan informasi yang berguna bagi para pemakai komputer. Disamping itu, monitor juga berfungsi untuk melihat apakah data ataupun program yang akan dimasukkan kedalam komputer sudah dalam keadaan benar atau belum.
Pada umumnya, monitor yang pada saat ini menggunakan tabung sinar katoda atau cathode ray tube (CRT). Dengan teknik scan-nya (raster scan technique) bisa dihasilkan gambar pada layar monitor. Sinar elektron yang dihasilkan akan bergerak secara cepat dan lurus serta bolak balik dari atas kebawah melintasi bagian belakang monitor yang dilapisi pospor. Pospor ini akan bersinar apabila ditembus sinar elektrone tersebut hidup atau mati, sehingga gambar-gambar dapat dibentuk pada layar monitor.

CPU

Unit pemrosesan pusat (CPU) adalah bagian dari sebuah sistem komputer yang melakukan instruksi dari program komputer, dan merupakan unsur utama melaksanakan fungsi komputer atau perangkat pengolahan lainnya. Unit pengolahan pusat melaksanakan setiap instruksi program dalam urutan, untuk melakukan operasi aritmatika, logika, dan input / output dasar dari sistem. Istilah ini telah digunakan dalam industri komputer setidaknya sejak awal 1960-an. [1] Bentuk, desain dan implementasi CPU telah berubah secara dramatis sejak awal contoh, tetapi operasi dasar mereka tetap sama.

CPU awal dirancang khusus sebagai bagian dari, lebih besar kadang-kadang satu-of-a-kind komputer,. Namun, metode ini mahal merancang CPU kustom untuk aplikasi tertentu umumnya telah memberikan cara untuk pengembangan produksi massal prosesor yang dibuat untuk satu atau banyak tujuan. Kecenderungan standarisasi umumnya dimulai di era mainframe transistor diskrit dan minicomputer dan telah dengan cepat dipercepat dengan mempopulerkan sirkuit terpadu (IC). IC telah memungkinkan CPU semakin kompleks harus dirancang dan diproduksi untuk toleransi pada urutan nanometer. Baik miniaturisasi dan standardisasi CPU telah meningkatkan kehadiran perangkat digital dalam kehidupan modern jauh melampaui penerapan terbatas mesin komputasi khusus. Mikroprosesor modern muncul dalam segala hal dari mobil ke ponsel dan mainan anak-anak.

Keyboard

Keyboard adalah alat untuk menuliskan perintah melalui aksara dan angka ke dalam layar monitor yang sebelumnya perintah tersebut diolah secara elektronis oleh Central Processing Unit (CPU). Bentuk keyboard secara umum sama dengan tombol pada mesin ketik, perbedaannya adalah jumlah tombol keyboard untuk aksara, angka dan perintah lainnya lebih banyak dari pada yang terdapat pada mesin ketik. Data atau perintah dapat dimasukkan ke dalam komputer melalui keyboard. Jadi keyboard merupakan penghubung antara manusia dan komputer.

Mouse

Mouse, atau “Tetikus” dalam istilah baku Bahasa Indonesia-nya, merupakan salah satu perangkat keras (hardware) dalam sebuah komputer, yang berfungsi sebagai alat input utama selain keyboard. Mouse dikategorikan sebagai sebuah Pointing Device (alat penunjuk/pemilih). Gerakan kursor di layar monitor mewakili pergerakan dari piranti mouse itu sendiri. Dengan mengarahkan kursor mouse pada icon/GUI (Graphic User Interface) tertentu, kemudian mengeksekusi perintah dengan cara meng-kliknya, seorang pengguna dapat menjalankan perintah tertentu pada program komputernya.
