Basics of Memory

Computer memory is called Random Access Memory (RAM). The knowledge stored in RAM can be accessed randomly, than sequentially. This means that knowledge can be present in any location at the same rate of speed. Other storage media, such as CD-ROM & hard drives, must wait while the drive spins to the correct location before the knowledge can be accessed.

Computer memory is fundamentally a storage area for the program code & the knowledge that program makes use of. Computer programs use RAM to write & retrieve knowledge, allowing for speedy knowledge retrieval & manipulation.

How Much RAM is ?

Fundamentally said, the answer is, as much as feasible. Keep in mind, though, time you have reached a positive upper limit, which is determined by the computer program(s) used, investment in more memory will see a diminished return.

Adding more memory is of the best ways to maximize computer performance. In the event you compare identical computer systems, the with the most memory will over-all be the faster. More RAM allows the computer to place more program instructions in to memory, relying less on the slower hard drive.

Think of 512 Megabytes (MB) as the base standard for a contemporary computer. With that you can multi-task (run several applications concurrently). For example, you can check electronic mail & download MP3s, without noticeable sluggishness.

Some applications, however, are more memory-hungry than others. Graphics programs, for example, are notoriously greedy. Memory needs are further exaggerated by the operating process used. Microsoft Windows is far more demanding than, say, Linux. Currently, most PCs use Windows, though.

Ought to you notice your computer slowing down, think about adding more memory. Before committing to that option, however, try de-fragmenting your hard drive with a utility (program) designed for that sole purpose. A fragmented hard drive is a common cause of stalled computer performance.

Types of RAM

Right now DDR SDRAM is the most popular memory module. DDR stands for Double Knowledge Rate, which means that the memory can be accessed times per clock-cycle. SDRAM, the acronym for Synchronous Knowledge Random Access Memory, has been the standard for memory modules for a decade.

To add memory to your computer, you must install modules with the correct contact layout. Before purchasing new memory, you must know which kind your motherboard will accept. The most common form factors are 168 pin, 184 pin & 200 pin.

You'll also need to know whether there are slots available on your motherboard. If all the slots are already in use, you'll must replace or all of the current modules with higher capacity ones. If there is at least free slot, you can fundamentally buy a used memory module & insert it in the empty slot.

A word of caution: whereas some motherboards can accept either SDRAM or DDR SDRAM, the categories cannot be mixed. You must settle on or the other. Check the motherboard manual first to select which kind of memory your computer requires.

& at last, when you are prepared to put in your new memory module, make positive of things: the power is off (for your safety) & you are electrically grounded (for your computer's safety).
