11.
What
is the function of voltage regulators?
Ans: The voltage regulator automatically maintains a
constant voltage level.
12.
What
are power protection devices? Give examples.
Ans: The device
that provides clean AC power to sensitive electrical equipment are called power
protection devices. Examples are: UPS, Volt Guard, Spike guard, etc.
13. Why is power protection
device needed in a computer system?
Ans: Power protection device is needed in a computer system to protect the computer system from damage and expensive data loss.

15. What is importance of
UPS in computer security system?
Ans: The importance of UPS in computer security system is that it controls fluctuation of electric voltage and provides enough backup electric power to the computer system when there is power failure.

16.
Why
do the computer system need regular maintenance?
Ans:
Computer system need regular maintenance to keep the computer hardware in good
working condition and it also helps to find out problems in hardware and
correct the problems before they cause several damages.
17.
What
should be done to protect computer system from fire and theft?
Ans:
Fireguards and fire extinguisher should be installed to protect computer system
from fire. Alarms, security lighting and closed circuit television cameras
should be used to protect computer system from theft.
18.
What
is surge protector?
Ans:
A device that shields computer and other electronic devices from surges in
electric power or transient voltage, that flow from the power supply.
