An Explanation of Ram Memory For Your Computer

The memory of a computer is the amount of storage on it. There are four types of memory namely, the Random Access, Read Only, the Operating System and the Basic Input/Output system.

When the computer is turned on, the BIOS is accessed first which is a flash based memory format and helps to boot the computer. ROM transfers data to RAM so that the applications can be run and performed, as instructed. The flash based memory operations happen in video, BIOS, and USB flash drives. The number of rewrites is limited and if a condition called "flash burn" happens wherein, the number reaches a saturation point; the flash device becomes corrupt and unusable.

Memory Card

The memory of the system can be placed in many places and in many ways, ranging from cache to buffer and ROM to RAM. As the functioning of the system and the speed depends upon how much memory it has, the sluggishness can be mainly attributed to inadequate RAM. Inadequate RAM can lead to shared RAM/memory where the system's memory will be shared between the CPU and the video memory. That is, when the computer uses its own memory for operating system and other applications, the memory is also shared to run video or graphics and the system would report significantly low memory.

So, while buying a computer, it is imperative to check the specifications to find out the amount of memory installed and its maximum capacity. This would help in the event of a need arising to upgrade the memory for enhanced performance. Basically, the memory requirement depends upon the applications that are run on the system, the operating system being used and the peripherals attached. For intense video gaming, VISTA like operating systems and peripherals like webcam, more memory would be needed. Normally, for ordinary PCs a memory of 2GB to 4GB would do. Where 4GB is the maximum of RAM you can have in a windows XP machine other newer operating systems such as Vista and Windows 7 can support much more.

If the memory installed in the computer is not sufficient even after up gradation, it is now feasible to have external storage in the form of memory cards. Technology has advanced in leaps and bounds in the memory card field and there are incredibly tiny ones that can store a library full of data, news and videos.

There are many formats of memory cards, the most popular being the SD (secure digital) card. The capacity of SD cards range from 1 GB to 12 GB and manufactures vie with one another day- in and day- out to bring in more and more innovations in memory cards. More memory means more convenience and better performance but it must be checked before upgrading whether the system is compatible.

Diagnosing Bad Computer Memory

Sometimes when your computer starts acting "funny" it can be a sign the memory is damaged. The good news is memory for computer systems is inexpensive and easy to replace.

Why Does Memory Fail?

Memory Card

When compared to other components, memory for computer systems has a very low failure rate. It has no moving parts, unlike a hard drive, and isn't subject the heat stresses the processor or video card are. However there are a number of problems that can damage memory.

Static electricity is a common culprit. If you were in there replacing some component and forgot to discharge static from your hand just one time, you might have sent an electric shock too weak to feel but strong enough to damage the delicate microcircuitry. However even if you have never had the case open, there are other possible causes.

A power surge can damage memory for computers. Some people expect a surge will be dramatic, with sparks and smoke, but in fact it can cause subtle damage that may take days to show up. Even if you have a surge protector, you still might have "dirty" power, which is electricity with unsteady voltage. This is especially true in older buildings. Finally, dust can get inside the case and short out memory contacts.

Signs of Bad Memory

Trying to diagnose computer problems can be frustrating since there are so many components that could be the cause. Software, viruses or a faulty Windows installation could be at fault as well. Failure of memory for computer systems has some distinct symptoms that stand out.

The infamous Blue Screen of Death (BSoD) is often a sign of hardware problems. If your computer locks up with a blue screen containing cryptic messages, this is a BSoD. If it happens just once then it may just be a fluke, but if it happens repeatedly that points to serious problems. Spontaneous reboots or system freeze can also indicate hardware problems.

An important question is when it happens. If it happens only when playing certain graphic-intensive computer games, that could be a sign of a memory problem. BSoDs or reboots during other memory intensive operations such as compiling software, video editing or viewing large images also are symptoms of memory problems.

Testing and Fixing The Memory

There are a number of utilities that can confirm the existence of memory errors, such as Microsoft's Windows Memory Diagnostic. By running a memory test utility, you confirm the error is actually in the memory and not some other component. By removing all memory modules except one and testing each one in turn, you can isolate which module is the problem.

Once you have confirmed the memory problem, replace the damaged module. Reseating the memory module may fix the problem, but this is often temporary. If the module is damaged, it should be replaced. Memory for computer systems in inexpensive, so don't take the chance a damaged module could corrupt important data.
