RAM - Random Access Memory

RAM (Random Access Memory) is the computer’s short-term memory. Program instructions and data are stored on the RAM chips, which the processor accesses directly.

If you have more RAM then you can store more instructions and data. The amount of RAM greatly affects the performance of the PC.RAM

However, if power is discontinued to the RAM, as when you shut off your PC, the contents of the RAM disappear. This is why hard driver disks are used for long-term storage.

Insufficient RAM can cause the computer to run slower. RAM chips are volatile, meaning that they immediately lose their data when the computer is shut off.

Memory is a one of major part of your computer, so get the good stuff.

A lot of people get really confused when it comes to memory, and it’s really not necessary. Some memory manufacturers will help you find compatible memory for your motherboard on their guidelines.

In most cases, standard non-parity, non-ECC memory will work just fine. Most boards today are still using SDRAM, although DDR-DRAM has really caught on and are a lot faster. In short, though, memory is not a huge issue and just buys what your motherboard requires. And, with today’s prices, buy lots of it.

Operating systems themselves require large amounts of memory. Windows XP’s bare minimum requirement is 128MB of RAM.

Important:
  1. The DDR in DDR DRAM is short for double data rate.
  2. SIMM is short for single in-line memory module.
  3. DIMM is short for dual in-line memory module.
  4. RIMM is short for rambus in-line memory module.
  5. VRAM and SGRAM is a specialized memory used on video cards.
