Choosing the right motherboard does not have to be a problem, even though there is a lot to consider. We will start off with the larger parts and move onto the things that are less essential.

Firstly is the socket type. The socket is where the processor (CPU) connects to the motherboard. There is no compatiblility between sockets, so it has to be the right one. The socket connection needs to match the connection of the processor you have or the one you intend to buy for the computer.
Most older Intel Pentium 4s utilize socket 478. Newer ones use socket 775. AMD chips utilised socket A for a long time, but now the AMD Athlon 64 series and Semprons use socket 939. Just check with someone as to what yours or your intended one will have.

Your choice of chip will have a lot to do with your needs, but choosing one with an up to date socket type will ensure slightly longer motherboard life as you can upgrade the chip for a while.

DDR is the RAM of choice for most systems, but some newer systems, which includes all Pentiums with socket 775 use DDR2. These two kinds are not interchangable and have a different number of pins. Both DDR and DDR2 come in different speed ratings measured in MHz. DDR has a usual 400MHz denoted as DDR400 or PC3200, while DDR2 can go a little higher and comes in slightly faster speeds. Just make it match what the board needs.

A motherboard must be chosen carefully, to both match all the other components and fit in the case you choose. A little bit of research before you buy will save a lot of hassle later on.

What are adwares, anyway? Adware or advertising-supported software is defined as any computer program or software package in which advertising and other marketing material are included with or automatically loaded by the software. Adwares are usually played back after installation. Some malicious adwares upload information about the computer or its user’s activities even without the consent of its user. Adwares most often take the form of banner ads that appear on pop up windows or anywhere on the computer screen.

Software applications display these advertising banners whenever a program is opened or through some other triggering mechanism. Most adwares are integrated into a free application. This is a way for the developers to recover the costs of creating such software. A prominent example of this is the Opera browser software, which is a free application but comes with a banner ad. The adware can only be removed once the user purchases and registers his copy of the software. It is also a revenue-generating mechanism. A company can sponsor adwares to capture more visitors and potential customers. Adware as a marketing strategy is just one of the many techniques used by websites to attract more traffic.

However, some adwares are more than just pesky and garish ads. In many cases, adwares accompany a more malicious program, which uploads information about the user collected without permission. The users surfing habits are then tracked; in some cases, the browser home page is altered or redirected to the adware company’s sponsoring site. These types of adwares are dangerous since they may jeopardize the computer system’s health. Aside from installing malicious software, they may also become an avenue for viruses to invade the system.

Adwares have come under fire not only because of their annoying presence in the form of pop ups and banners but also in the way they invade the privacy of the user. Trackware and Spyware are just two of the “evil” forms that adware can take. That is why most computer users make an effort to get rid of these adwares. Because of the annoying nature of pop-up adware, most browsers now employ an adware blocking system through the form of a pop-up blocker or adware blocker. Browsers such as Microsoft’s Internet Explorer and Mozilla’s Firefox all use pop-up blockers, which instantly block or close any window that is triggered by adware in the sites that the user visits. These steps have significantly reduced the number of irritating adware that pop up every time a site is opened.

Most antivirus programs and utilities now feature an adware search and removal system. These programs indexes known adwares and spywares in the internet universe and searches for it in the user’s computers system then subsequently quarantines or deletes the malicious files. Nevertheless, despite the numerous efforts against adwares, they continue to plague web surfers with their showy ads and banners as well as the nasty programs they introduce into the computer system. As the sage of the annoying adware continues, web surfers are also equipped with the best tools and utilities to combat them.

There are several malicious programs which can come bundled with a free screensaver. These will mainly be viruses, spyware, adware, and toolbars. There are a few variations within these programs, but in the main they are considered undesirable, unless the user specifically requests them. And out of that list, the only one that you would even consider installing would be a friendly toolbar. But more on that later.

Below is a brief run-down of each type of malicious programs that you would want to avoid:

Viruses: These must be avoided at all costs as they can detrimentally harm your computer, often to the point of losing unrecoverable data. If you are afraid of being infected with viruses, only download software from trusted sites where programs are verified and tested, such as at Download.com. Download.com also host their own files, which means that software cannot be altered at a later date to include any viruses.

Spyware: These are programs which are used to unethically track and spy on your internet online activities. The data can then be sold to advertisers or used to change your browser and computer functions. Spyware is one of the worst type of bundled software, and can be difficult to remove.

Adware: Adware is a little less scary than spyware, though no less annoying to the average computer user. Adware programs will continually display popups and unwanted adverts while you are browsing. Sometimes you may not even realise that you have adware unless you notice an excessive amount of popups during your normal surfing (where there were no popups before).

Toolbars: Finally we have toolbars, which is a mixed basket. Some toolbars are actually quite useful, such as the Google Toolbar, or some that offer increased entertainment experience like the StumbleUpon toolbar. Having said that, there are other toolbars which are used as a means of displaying ads and are hard to uninstall. Some of these unwanted toolbars come bundled with free screensavers or software, often from some so called ‘big name’ companies.

It is extremely important that you do your research before you download screensavers. Read the Terms of Service, and Conditions of Use on the websites, as companies are required by law to inform users what they would be installing.

Make sure you read the fine print. Not just what is on the download page. Sometimes they will say ‘No spyware’, but they do not mention anything about adware. Are you prepared to put up with some (or a lot) of advertisements for a free screensaver? Most people certainly should not.

If you care about output quality more than anything else and you’re on a tight budget for purchase price, then Epson Inkjet Cartridge may well be your inkjet of choice. It offers among the best overall output quality of any inkjet, period. It ensures low volume, low cost, good qulaity and ability to reproduce lifelike photographs.

Epson printer cartridges are subjected to slight agitation for the settled colorant particle to re-disperse. The printer ink is restored to its fully dispersed state by the high sped flow induced by the initial filling action of head cleaning. This helps the users to print with ink with a uniform concentration.

Epson inkjet manufacturers are building faster products that create vivid, crisp images. Epson’s Stylus Color 850 and 850N inkjets; for instance, are 20 percent faster than their predecessors. These new inkjet printers are versatile, too; they handle envelopes, transparencies, labels, fabrics, photos, and various sizes and weights of paper.

Epson has recently announced some new types of inkjet cartridges with a new design and many new features. Epson Inkjet Cartridge is available at big discount prices and offer huge savings on your printers.

It is true to say that Epson’s new ink cartridges do not look very different from other ink cartridges. However, these new cartridges are packed with various new technologies designed to ensure the highest levels of performance from an Epson printer. Epson believes that the mission of an ink cartridge is to render the maimum benefit to all its users who have considered Epson as their printer brand.

Bookworm is not very difficult as it is normally a turn-based game. This means you have all the time in the world to think of your next move. It is up to you whether you want to form words as fast as you can or to think long and hard to come up with the best possible combination. The important thing to bear in mind is to avoid the red tiles and getting rid of them so as not to let them reach the bottom.

After accumulating a certain number of points, you get promoted to different levels. It is quite geeky as you can progress to titles such as Senior Librarian. I would take that as a compliment though!

You can either play the online game or download a free time-limited trial version. You can play the online game as long as you want although this version has limited features. It also has interruptions as pop ups may come out from time to time.

If you get the full version, you have the option of playing either the turn-based classic mode or the speedy Action mode. You also have more bonuses – gold, sapphire, and diamond! Another plus is that you can learn more with the on-screen definition of some not so common words.

So if you are in the market for a fun, relaxing, worthwhile game, Bookworm just might be what you are looking for.

Don’t panic! Everything may not be lost just yet, and you may be able to recover all information without a sweat. To maximize your chances of successful recovery, minimize your activity on the computer where the lost files were. While you cannot be completely sure that Windows does not write anything on the disk that stores your lost files, the goal is essentially to limit disk write operations until you get back all important data from that disk. Any data that’s written on a disk that contains deleted or inaccessible data on it can, and probably will, overwrite the deleted files on the disk and destroy information that was stored in them.

Anecdotally, one of the worst things you can do is looking for a tool that will undelete or recover your XLS files, installing and trying out such tools in action. On a typical PC, any Web page you open in a browser will cause several file writes to a hard drive, reducing your chances of successful data recovery. Any program that you download or install is also written to your hard disk. Finally, as not all products are equal, running a wrong type of data recovery application bears an unacceptably high risk of losing your lost Excel spreadsheets forever.

DiskInternals Excel Recovery is designed specifically to find and recover Microsoft Excel XLS spreadsheets safely and securely, no matter how badly your hard drive or the file system are damaged. If you simply deleted an XLS file, DiskInternals Excel Recovery will look up the file system to find all XLS files that were deleted recently, and test each file for the possibility of successful recovery. In bad cases or if your hard drive crashed or the file system is corrupt, DiskInternals Excel Recovery will scan entire hard drive’s surface in order to locate Microsoft Excel spreadsheets that aren’t marked in the file system. The product uses a list of signatures associated with Microsoft XLS file format in order to detect precisely the beginning and end of each and every Microsoft Excel spreadsheet on your hard disk, extracts and validates their contents and metadata on the fly. This method works even on disks that are completely inaccessible in Windows!

The product matches the results obtained with the file system scan against those obtained by scanning surface of the hard disk, and displays the complete list of recoverable Excel spreadsheets along with their file names, metadata and contents, giving you the best possibility of successful recovery.

If you only need to recover the latest version of an Excel spreadsheet, you can use “On the Fly” filters that allow to only showing XLS files with specific title, created by specific author, or the files that contain certain text, are of a certain size, or are last saved on a specific date. The free version of DiskInternals Excel Recovery allows full file preview to ensure that you can recover exactly the files you need.

Download and try an evaluation version for free from http://www.diskinternals.com/. You only need to purchase when you see for yourself that DiskInternals Excel Recovery provides you complete recovery of your XLS files in your particular circumstances.

Trunking is simply enabling two or more switches to communicate and send frames to each other for transmission to remote hosts. There are two major trunking protocols that we need to know the details of for exam success and real-world success, but before we get to the protocols, let’s discuss the cables we need.

Connecting two Cisco switches requires a crossover cable. As you know, there are eight wires inside an ethernet cable. In a crossover cable, four of the cables “cross over” from one pin to another. For many newer Cisco switches, all you need to do to create a trunk is connect the switches with a crossover cable. For instance, 2950 switches dynamically trunk once you connect them with the right cable. If you use the wrong cable, you’ll be there a while!

There are two different trunking protocols in use on today’s Cisco switches, ISL and IEEE 802.1Q, generally referred to as “dot1q”. There are three main differences between the two. First, ISL is a Cisco-proprietary trunking protocol, where dot1q is the industry standard. (Those of you new to Cisco testing should get used to the phrases “Cisco-proprietary” and “industry standard”.) If you’re working in a multivendor environment, ISL may not be a good choice. And even though ISL is Cisco’s own trunking protocol, some Cisco switches run only dot1q.

ISL also encapsulates the entire frame, increasing the network overhead. Dot1q only places a header on the frame, and in some circumstances, doesn’t even do that. There is much less overhead with dot1q as compared to ISL. That leads to the third major difference, the way the protocols work with the native vlan.

The native vlan is simply the default vlan that switch ports are placed into if they are not expressly placed into another vlan. On Cisco switches, the native vlan is vlan 1. (This can be changed.) If dot1q is running, frames that are going to be sent across the trunk line don’t even have a header placed on them; the remote switch will assume that any frame that has no header is destined for the native vlan.

The problem with ISL is that is doesn’t understand what a native vlan is. Every single frame will be encapsulated, regardless of the vlan it’s destined for.

Switching theory is a big part of your CCNA studies, and it can seem overwhelming at first. Just break your studies down into smaller, more manageable parts, and soon you’ll see the magic letters “CCNA” behind your name!

The good thing about a download manager is the fact that it has a memory, and can remember where a download came from, how big the file was, and how much of the file you have downloaded in case it has to go back and pull that information back at a later date. When you use Internet Explorer to download files, and your in the middle of downloading a file and the power goes out. You have to start downloading the files all over again, but not with a download manager.

As said before, a download manager has sort of a built in memory per say. If your power goes out in the middle of a download, once your computer regains Internet access, then the download manager will go right back to where the download left off and continue on from that point.

Also, with a download manager, it puts all the controls right in the users hands. If they are downloading multiple files, the user has the ability to pause certain downloads, to increase bandwidth to the other downloads, and then resume that download when ever the user is ready.

Large companies are looking to tighten the noose around those bad hackers, consumers are demanding more security and more privacy for there home computers, and who wouldn’t, credit card fraud and identity theft has not decreased it has only increased.

Hackers who like to hack into bank accounts are going to have a harder time doing that. Some online banking companies are asking there customers to take a further step in the login process when logging into there bank accounts. For example, some banks are asking there customers to enter their user ID on one page and then enter their password on the next page; this makes it more difficult for hackers. But don’t ever feel like you are safe, keep your guard up and don’t fall for any phony emails that ask you to go to a fake look a like bank website and enter your user name and password. If you do get one of those fake emails call your bank first, and ask them if they sent you the email, and you can also forward the email to the banks technical support team.

Thanks to companies like Webroot there are programs that can help you keep your computer secure and free of spy ware and ad ware, with their Spy Sweeper software which I highly recommend. Webroot also offers a great firewall that your computer should not be without. Go to AME Computers Spyware and Malware page for more information on these great products.

Another good move toward security and spam is that there are some ISP’s that are offering free spam filters, this helps cut down on the amount of junk mail reaching your inbox. The newer version of Outlook has built in junk mail filter, but what’s the point in having a filter if you have to go and filter through the spam filter that Outlook provides.

The flip side to all of this is the cost to consumers. Spyware and viruses can cost companies, and the average consumer thousands of dollars a year. Companies implementing new security hardware pass on those expenses to there customers, so it is not good for the consumer or the business. Microsoft Vista operating system has some built in features to help keep you safe; however there still may be a need for third party software to protect against spyware and viruses.

It’s a never ending battle between the good guys like Webroot and Lava Soft and the bad guys like the hackers and spammers. Do your part and fight the good fight.

Hosted Solution – Applicant Tracking Systems
Applicant tracking systems and hosted solutions are a logical combination. While a company may install, debug, upgrade and program its own applicant tracking systems, the question is why? For companies in a niche employment market, it may make sense because the cost per employee of their applicant tracking systems is low. For example, a company reviewing say twenty resumes per hire. The cost of missing the one in a thousand employee of course is HUGE. Hosted applicant tracking systems are more likely to uncover the one in a thousand employee as well better average workers than as company’s own applicant tracking systems.

Search & Data Mining – Applicant Tracking Systems
A day late and a dollar short in the HR department can cost a company dearly. In some companies, just a few people review job applicants. Then there are holding companies in which many people mine the HR database for positions with related divisions in the group. The economy of scale offered by the joint applicant tracking systems reduces the overall employee acquisition cost for individual companies and the holding group.

Interview Sharing – Applicant Tracking Systems
How many employees are hired without a job interview at your company? Not many, that’s for sure. Effective applicant tracking systems recycle good job applicants back to the company’s database with added comments for other managers to review. Their comments may disqualify the applicant for a position, saving time spent and an additional needless interview. On the other hand, the comments may uncover the perfect candidate in a hard to fill position before they find a job with a different company.

Employee Satisfaction – Applicant Tracking Systems
Sometimes it seems companies are insensitive to potential employees. The hiring process is stressful for job seekers shuffled from person to person, concerned by salary and job benefits. Effective applicant tracking systems accelerate the hiring process and promote long term employee satisfaction. Also, happy employees refer their friends saving time and money in the long run.
