A memory module is very important to your PC memory or your Mac memory. Without memory modules you would not be able to use the machine for anything at all. It is through the use of memory modules that your computer can perform by accessing information in a certain order. By doing a computer memory upgrade, you can increase the speed of your machine and provide for opportunity to run more programs at one time.

Here are two terms you will hear used often when talking about a memory module and it refers to the capabilities of each one. The first is a DIMM which are Dual In Line Memory Modules. A SIMM is Single In-line Memory Modules. The faster a computer or CPU can access the information by keeping memory in a cache, the quicker the machine actually is and will perform.

The DIMM is used for a RAM, or a Random Access Memory upgrade. Desktop computers and notebooks need this RAM and is one of the easiest and cheapest ways to increase your memory. But you will need to know a few things before you can do the upgrade. First, a SIMM uses a 32 bit data path, whereas a DIMM uses a 64 bit data path. Initially, the DIMM is still the faster unit to have running.

If you are looking to replace the DIMM, then you need to know what you are currently using. You will have to add up your memory capacity by counting groups of chips. Chips are measured in bits so you will have to do a little math. The convert bits into bytes, the formula is the number of bits divided by 8 bytes. The resulting number is the amount of mega bytes that you are currently using.

There are a few ways you can increase the speed of your computer. You know the acronyms so now you need to know the process of upgrading. You can add memory modules chips to increase the memory and thereby increase your computer performance. You can find these modules at a discount computer hardware store, buy computer memory on line or contact your local computer repair professional and let them perform the upgrades for a reasonable fee if you feel that you cannot do the upgrades yourself.

Boot Sector Viruses are one of the most difficult types of virus and can be the most destructive. The Reason they are called a boot sector virus is that they reside in the area of the hard drive responsible for booting up your computer.

This can be a real headache and can be difficult to diagnose and quite often is impossible to repair

This can be a big problem, because a cleverly designed boot sector viruses can convince your computer that there is no virus at all when it loads. The best way to remove this type of virus is to make a backup “clean” disk as part of your computer maintenance.

This disk loads your computer when you stick it in the drive, so it is not loading from the boot sector, which has already been contaminated by a virus. This way, you can load your computer virus free, and then clean the virus off of it once you have installed some suitable anti Virus software.

Some people would say that the best way to prevent yourself contracting a boot sector virus in the first place is to switch operating systems away from Microsoft Windows.

While this may seem like good advice initially once you factor in buying and learning new software it is not so practical.

Boot sector virus removal isn’t the only protection you might need on your computer. You will need ant- spyware software as well. Spyware is a little like viruses,but much less harmful.

When you visit certain websites with spam, they will put a program in your web browser which keeps track of your information and sends it back to them. It follows what websites you go to, what you buy, etc., and uses it to market things to you.

It also slows down your computer and opens pop-up windows which you don’t want to see repeatedly, which is very distracting and annoying.

Some adware can even devert your web browser, sending you to websites you don’t want to see, and stopping you from getting to the ones which you are trying to get to. Fortunately, these harmful nuisances are easily removed using one of any number of commonly avalable adware removal programs.

The long and short of it is make sure your system is adequately protected against any for of virus, spam or adware wherever possible. And when (not if, if you want to stay virus free)you purchase software for this purpose make sure you keep it up to date.
