C) OLED
D) CRT
Correct Answer: C) OLED
Explanation: OLED displays offer better color accuracy, faster refresh rates, and better contrast than traditional LCD displays.
Question 05
What is the main purpose of thermal paste?
A) Increase CPU speed
B) Prevent CPU overheating
C) Improve power efficiency
D) Provide electrical insulation
Correct Answer: B) Prevent CPU overheating
Explanation: Thermal paste improves heat transfer between the CPU and the heat sink
Question 06
What does DDR in DDR RAM stand for?
A) Direct Data Retrieval
B) Dynamic Data Response
C) Double Data Rate
D) Digital Data Ram
Correct Answer: C) Double Data Rate
Explanation: DDR RAM transfers data twice per clock cycle, effectively doubling its data rate compared to earlier types of RAM.
Question 07
What is the function of a NIC (Network Interface Card)?
A) Increase storage capacity
B) Provide network connectivity
C) Manage system cooling
D) Enhance CPU performance
Correct Answer: B) Provide network connectivity
Explanation: A NIC allows a computer to connect to a network, either wired or wireless.
Question 08
What does UEFI stand for?
A) Universal External Firmware Interface
B) Unified Extensible Firmware Interface
C) Universal Ethernet Firmware Integration
D) Unified External Function Interface
Correct Answer: B) Unified Extensible Firmware Interface
Explanation: UEFI is a modern firmware interface that provides better booting and security features compared to the older BIOS.
Question 09
Which power supply voltage is typically used to power the CPU?
A) 3.3V
B) 5V
C) 12V
D) 1.5V
Correct Answer: C) 12V
Explanation: The 12V rail is used to power components that require more power, including the CPU.
Question 10
What is the primary function of a hard drive’s actuator arm?
A) Read and write data to the drive’s platters
B) Provide power to the platters
C) Spin the platters at high speed
D) Manage airflow inside the drive
Correct Answer: A) Read and write data to the drive's platters
Explanation: The actuator arm moves across the platters to read and write data to the magnetic surfaces.
Question 11
What does the CMOS battery power?
A) The CPU when the computer is off
B) The BIOS settings and system clock
C) The GPU during boot-up
D) The RAM when the computer is in sleep mode
Correct Answer: B) The BIOS settings and system clock
Explanation: The CMOS battery maintains the system clock and stores BIOS settings when the computer is powered off.
Question 12
What does the term “full-duplex” refer to in networking?
A) Sending and receiving data, but only one at a time
B) Sending and receiving data simultaneously
C) Sending data without confirmation
D) Sending multiple streams of data
Correct Answer: B) Sending and receiving data simultaneously
Explanation: Full-duplex allows data transmission in both directions at the same time, improving network efficiency.
Question 13
What is the primary advantage of a solid-state drive (SSD) over a traditional hard disk drive (HDD)?
A) Higher capacity
B) Lower cost
C) Faster read/write speeds
D) Greater durability
Correct Answer: C) Faster read/write speeds
Explanation: SSDs offer much faster data access and retrieval times because they have no moving parts.
Question 14
Which connector is most commonly used for wired internet connections?
A) RJ45
B) USB
C) HDMI
D) RJ11
Correct Answer: A) RJ45
Explanation: RJ45 connectors are used for Ethernet cables in wired network connections.
Question 15
What is a common use for a punch-down tool in networking?
A) Test cable speeds
B) Strip wires
C) Terminate cables into patch panels
D) Measure signal strength
Correct Answer: C) Terminate cables into patch panels
Explanation: A punch-down tool is used to secure wires into patch panels or keystone jacks.
Question 16
What is the maximum data transfer speed of a PCIe v3.0 x16 slot?
A) 8 GBps
B) 16 GBps
C) 32 GBps
D) 64 GBps
Correct Answer: B) 16 GBps
Explanation: PCIe 3.0 x16 slots support a maximum data transfer speed of 16 GBps.
Question 17
What does RAID 1 offer that RAID 0 does not?
A) Data striping
B) Increased speed
C) Redundancy through mirroring
D) Parity-based fault tolerance
Correct Answer: C) Redundancy through mirroring
Explanation: RAID 1 mirrors data across two drives, offering redundancy that RAID 0 does not provide
Question 18
What is the main function of a heat sink in a computer system?
A) Reduce power consumption
B) Store extra data
C) Dissipate heat from components
D) Provide additional memory
Correct Answer: C) Dissipate heat from components
Explanation: Heat sinks help cool components like the CPU by transferring heat away from them.
Question 19
What type of memory is used to store firmware in a computer system?
A) RAM
B) SSD
C) ROM
D) HDD
Correct Answer: C) ROM
