this diagram is the main components of a computer. a computer is a mane device that takes in the input and dose something useful with it in order to give us usfull out put
cpu
1.what is cpu =central prosessing unit
2.what does it do = it is the brains of a computer
3. how does it work =it sits in the mother board
it stores the results inthe memory
4.how is the speed mesured=The most common measure of CPU speed is the clock speed Hz 1Hz = 1 cycle MHz 1MH =1000000 1GHz =1billion modern cpu run at approx 3GHz

ram
1. what dose it mean = random access memory
2.what is stored in ram = RAM is a fast temporary type of memory in which programs, applications and data open programs
3. what does volatile mean=Volatile means something changing or changeable.
4.why does a computer need ram = to store stuff vital stuff because it is faster than storage it is quick and convenient use of space

3. what does volatile mean=Volatile means something changing or changeable.

rom
1.what does ROM mean=read only memory
2.what is stored in a ROM chip= every stored program bios enables cpmputer to
3.why is ROM needed in a computer= you couldent store programs on it
4.can the content of ROM usually be changed = rom can sometimes be changed to romz
5. is rom volatile or non viotile =rom is non volatile
