- 1What does RAM stand for?Random access memory.
- 2What does VOLATILE mean?Volatile memory is computer storage that only maintains its data while the device is powered.
- 3Is RAM volatile?Yes.
- 4What does ROM stand for?Read Only Memory.
- 5Is ROM volatile?No.
- 6What is BIOS?Basic Input Output System.
- 7What is Virtual Memory?If your computer lacks the random access memory (RAM) needed to run a program or operation, Windows uses virtual memory to compensate. Virtual memory combines your computer's RAM with temporary space on your hard disk. When RAM runs low, virtual memory moves data from RAM to a space called a paging file.
- 8What is Cache Memory?Cache Memory is a special type of memory. The CPU looks in the cache for the data it needs. If the data is there it will retrieve it and process it.

- 9What type of memory is used when the RAM runs out?Virtual Memory
- 10Does ROM or RAM hold the computer's operating system? (E.G. Windows)ROM.
- 11What does RAM store?Instructions for the CPU to process.
- 12What does CPU mean?Central Processing Unit.
- 13Do NOT gates take on bit as in input and 1 as an output?Yes.
- 14Do AND gates take 2 bits as inputs and if both inputs are 1, then the output is 1, otherwise the output is?Yes.
- 15Do OR gates take 2 bits as inputs, and if both inputs are 0, then the output is 0, otherwise the output is 1?Yes.
- 16Is this an AND gate?Yes.
- 17Is this an OR gate?No.
- 18Is this an OR gate?Yes.
- 19Is this an NOT gate?Yes.
