Data Storing

Computer Systems store data in two store:
1) Main Store e.g chips in side the centre processing unit
2) Backing Store e.g magnetic disk

Main Store (Memory)
Here data is held temporarily while processing takes place. The data held in the memory is instantly available to the computer unlike backing storage which has to be accessed on disk or tape.
There are two types of memory or main store:

• read only memory (RAM)
• random access memory (ROM)
