COMPUTER MEMORY


ROM:
  • ROM stands for READ ONLY MEMORY.
  • Is "built-in" computer memory containing data that normally can only be read, not written to. ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on. Unlike a computer's random access memory (RAM), the data in ROM is not lost when the computer power is turned off. The ROM is sustained by a small long-life battery in your computer.

    If you ever do the hardware setup process with your computer, you effectively will be writing to ROM.

RAM:


RAM is a short form for RANDOM ACCESS MEMORY.

Every time you open a program or something in the computer, it gets loaded from the hard drive into the RAM. This is because reading data from the RAM is much more faster than reading data from the hard drive. Running programs from the RAM of the computer allows them to function without any pause time. The more RAM your computer has, the more data can be loaded from the hard drive into the RAM, which can effectively speed up your computer.

Types of RAM

There are two different types of RAM:
  • DRAM (Dynamic Random Access Memory)
  • SRAM(Static Random Access Memory)
