A) RAM
B) SSD
C) CMOS battery
D) Power supply
Correct Answer: C) CMOS battery
Explanation: The CMOS battery stores BIOS settings such as system time and hardware configuration.
Question 30
What is the purpose of an uninterruptible power supply (UPS)?
A) To provide backup power during a power outage
B) To increase CPU performance
C) To reduce GPU temperature
D) To store additional data
Correct Answer: A) To provide backup power during a power outage
Explanation: A UPS provides temporary power in the event of a power outage, allowing users to save their work and shut down safely.
Question 31
Which port is commonly used for video output on modern laptops?
A) VGA
B) HDMI
C) RJ11
D) PS/2
Correct Answer: B) HDMI
