Sonya
, a user, reports that she works in an electrically unstable environment where brownouts are a
regular occurrence. Which of the following will you tell her to use to protect her computer?
A.
UPS
B.
Multimeter
C.
SMPS
D.
CMOS battery
Explanation:
UPS stands for Uninterruptible Power Supply. It is a device that provides uninterrupted
electric power even after power failure. When a power
failure occurs, the UPS is switched to the battery provided inside the device. It is used with
computers, as power failure can cause loss of
data, which has not been saved by a user.
Answer option C is incorrect. Switch Mode Power Supply (SMPS) is a device that converts raw input
power to controlled voltage and current for
the operation of electronic equipment. SMPS uses switches for high efficiency.
Answer option D is incorrect. Complimentary Metal Oxide Semiconductor (CMOS) is a chip installed
on the motherboard, which stores the
hardware configuration of a computer.
