- ROM

'read-only memory'
- ROM is a 'built-in' memory and
the data stored in ROM can only
be read and is mostly used for
firmware updates.
- ROM can not be changed
by the program or user.
- ROM still keeps its memory
after the computer is turned off.

- RAM
- It stands for 'random
access memory'
- RAM is a fast type of memory in
which programmes, applications
and data are stored
- RAM can not keep any
memory once the computer is
turned off.
- Static RAM is fast and expensive
whereas dynamic RAM is slower
and less expensive.
- Volatile memory is usually faster than
forms of mass storage such as hard
drives and can protect sensitive
information which becomes unavailable
on power-down.
