All computers come with main memory as well as backing storage. give a reason why the following are needed.
RAM:
Most data is stored on the computers hard disk drive, but it can be quite slow to retrieve data from the hard drive. RAM, however is very quick when it comes to retrieving data, so the computer transfers programs and files into the RAM when they are in use.

ROM:
ROM is important to the computer's functionality because it retains all of the data even if the computer is powered off. ROM is usually what is used to store the data in order to even boot up a computer.

RAM and ROM are types of storage.
(a) Describe the differences between RAM and ROM.
- RAM is volatile - so data is lost when computer is turned off and ROM is not volatile.
- RAM you can change your data but with ROM you cannot
- RAM - temporary store of data and ROM reads only memory.

explain what RAM and ROM are used for.
A RAM is faster and requires less power than DRAM and, in modern computers, is often used as cache memory for the CPU.
ROM can store the instructions for the computer to start up when it is turned on again
