Random Access Memory (RAM)
Random Access Memory (RAM) is the part of the computer that temporarily stores the instructions that the computer is running, and the data it is processing.
|
The storage capacity of memory is measured in Bytes.
Usually RAM can hold millions of bytes of data, so you will see capacities measured in:
Megabytes (MB) or 1,000,000 (1 million) Bytes Gigabytes (GB) or 1,000,000,000 (1 billion) Bytes
So, if a computer has 2GB of RAM, it can hold 2 billion bytes of data and instructions at any time.
Read-Only Memory (ROM)
Read-Only Memory (ROM) is used in most computers to hold a small, special piece of software: the 'boot up' program.
