programs, that are in active use but currently in a waiting state can be shifted
to this area (swapped out) so that others can run in RAM. It is a form of virtual
memory. Also called a swap file.

equipment, such as a computer system, and the AC power source to protect

power, it switches over to the battery giving you time to save data and close
down the system.
upload:
To send a file to another computer through a modem. See also download.

compress files and check for viruses.

only as long as the computer is turned on.
