RAM is . . .?

(a)  

ROM stands for...

• Read Optical Memory
• Random Only Memory
• Read Only Memory
• Random Optical Memory

Why is Virtual Memory needed in a computer system?

• It is used as a fast type of memory for programs currently in use to speed up the performance of a computer.
• When several programs run at the same time, the RAM can be full. Instead of closing programs the Operating system uses virtual memory to store some data.

Where is data stored when it is Virtual Memory?

• It is stored on a area of a secondary storage device e.g. hard disk drive.
• It is stored in the RAM.
• It is stored in the ROM.
• It is stored in an optical drive e.g. CD.
