About RAM
Submitted by Sandhya on 23/06/2009 - 04:10 PM
RAM is called Random Access Memory. There's too much "stuff" on your computer's hard disk to use it all at the same time. During the average session sitting at the computer, you'll probably use only a small amount of all that's available. The stuff you're working with at any given moment is stored in random access memory (often abbreviated RAM, and often called simply "memory"). The advantage using RAM to store whatever you're working on at the moment is that RAM is very fast. Much faster than any disk. For you, "fast" translates to less time waiting and more time being productive.

So if RAM is so fast, why not put everything in it? Why have a hard disk at all?

 The answer to that lies in the fact that RAM is volatile. As soon as the computer is shut off, whether intentionally or by an accidental power outage, every thing in RAM disappears, just as quickly as a light bulb goes out when the plug is pulled. So you don't want to rely on RAM to hold everything. A disk, on the other hand, holds its information whether the power is on or off.

Types of RAM :

  • SRAM : Static random access memory.
  • DRAM : Dynamic random access memory.
  • FPM DRAM : Fast page mode dynamic random access memory.
  • EDO DRAM : Extended data-out dynamic random access memory.
  • SDRAM : Synchronous dynamic random access memory.
  • DDR SDRAM : Double data rate synchronous dynamic RAM.
  • RDRAM : Rambus dynamic random access memory.
  • CMOS RAM : Small amount of memory.
  • VRAM : VideoRAM or Multiport dynamic random access memory (MPDRAM.
  • SGRAM : Synchronous graphics RAM.
  • Credit Card Memory : Proprietary self-contained DRAM memory module, special slot for use in notebook computers.
  • PCMCIA Memory Card : Self-contained DRAM module for notebooks.
