- 1what does RAM stand forrandom access memory
- 2what does ROM stand forread only memory
- 3name all the types of storageflash storage , optical media, cloud, hard drive, magnetic disc
- 4what is virtual memoryvirtual memory is where the ram is full or the cpu has too many commands so it goes to a section of the hard disk what takes a longer journey so it goes slower and when you click of a tab and go back on it takes longer to reload even though you have been on it before
- 5what holds the operating systemROM
- 6what does cpu stand forcontrol processing unit
- 7what does the cpu dothe cpu holds the fetch decode and execute cycle. rom gives instructions to the cpu the cpu gets the instruction processes it then executes it. In side the cpu is the cores what are clock speed what is how many instruction are done per a second like 1 mega hertz is a million instruction per a second. you can also get quad core what is 4 cores what is 4 sets of instructions are at one cpu is non volatile because you need the cpu to start your computer up.
