What term identifies a blank screen or animation that automatically displays on a computer monitor after a specified period of inactivity?
a. control panel
b. desktop
c. screen saver
d. shortcut

The correct answer is C. Screen saver. The screen is filled with animated objects when the computer is kept in idle and inactive for a fixed period of time. The time when screen savers are triggered can be set in the control panel of the computer. The initial use of the screen saver was to prevent the heating of the monitors, which was then cathode ray tubes (CRT), due to steady and fixed display. Now, a screen saver can protect users with password prompts when a computer is left unattended for a certain time.
