A) PSU
B) Northbridge
C) VRM
D) GPU
Correct Answer: C) VRM
Explanation: Voltage Regulator Modules (VRMs) ensure the CPU receives the correct voltage for stable operation.
Question 22
Which of the following memory types is non-volatile?
A) RAM
B) ROM
C) DRAM
D) SRAM
Correct Answer: B) ROM
Explanation: ROM retains data even when the computer is powered off, making it non-volatile.
Question 23
What is a possible drawback of using an aftermarket power supply in a desktop?
A) Lower power efficiency
B) Compatibility issues with certain components
C) Increased performance
D) More cooling requirements
Correct Answer: B) Compatibility issues with certain components
Explanation: Aftermarket PSUs may not always be compatible with all system components or offer the required power.
Question 24
What does RAID 5 use to provide fault tolerance?
A) Mirroring
B) Parity
C) Striping
D) Dual controllers
Correct Answer: B) Parity
Explanation: RAID 5 uses parity data, which allows for fault tolerance by reconstructing lost data if a single drive fails.
Question 25
Which type of motherboard form factor is the smallest?
A) ATX
B) Micro-ATX
C) ITX
D) E-ATX
Correct Answer: C) ITX
Explanation: ITX is the smallest form factor among the listed options, often used for compact systems.
Question 26
What is the function of a cache in a CPU?
A) Provide additional storage
B) Store frequently accessed data for quick retrieval
C) Manage network connections
D) Increase power efficiency
Correct Answer: B) Store frequently accessed data for quick retrieval
Explanation: Cache memory stores frequently accessed data to reduce the time the CPU spends retrieving data from main memory.
Question 27
What type of connection is Thunderbolt commonly used for?
A) Data storage only
B) Video output and data transfer
C) Ethernet
D) Audio
Correct Answer: B) Video output and data transfer
Explanation: Thunderbolt ports are versatile, supporting both high-speed data transfer and video output.
Question 28
What does the acronym USB stand for?
A) Universal Serial Bus
B) Uninterrupted Service Band
C) Universal Synchronous Buffer
D) Unified Storage Bus
Correct Answer: A) Universal Serial Bus
Explanation: USB (Universal Serial Bus) is a standard for data transfer and connection between devices.
Question 29
Which of the following is a type of video connector?
A) RJ45
B) HDMI
C) SATA
D) USB-C
Correct Answer: B) HDMI
Explanation: HDMI is a widely used video connector for transmitting high-definition video and audio.
Question 30
What is the function of a power supply unit (PSU)?
A) Provide cooling to the GPU
B) Convert AC power to DC power
C) Store BIOS settings
D) Increase CPU performance
Correct Answer: B) Modem or telephone connections
Explanation: RJ11 connectors are commonly used for telephone and dial-up modem connections.
Question 31
What is a common use for an RJ11 connector?
A) Network connections
B) Modem or telephone connections
C) Video output
D) Audio transmission
Correct Answer: b) Router
Explanation: A router connects multiple networks and forwards data between them using IP addresses.
Question 32
Which RAID level is known as disk striping without parity and offers no redundancy?
A) RAID 0
B) RAID 1
C) RAID 5
D) RAID 10
Correct Answer: A) RAID 0
Explanation: RAID 0, also known as disk striping, splits data across multiple disks to increase performance but does not provide any redundancy. If one disk fails, all data is lost.
Question 33
Which type of memory is typically used as cache in a CPU?
A) DRAM
B) ROM
C) SRAM
D) Flash
Correct Answer: C) SRAM
Explanation: SRAM (Static RAM) is faster than DRAM and is typically used for CPU cache because of its speed and efficiency.
Question 34
What is the primary function of an SSD in a computer?
A) Provide network connectivity
B) Store data persistently
C) Manage power distribution
D) Monitor temperature
Correct Answer: B) Store data persistently
Explanation: Solid-State Drives (SSDs) store data persistently using flash memory, making them faster than traditional HDDs.
Question 35
Which port is most commonly used for video output in modern computers?
A) VGA
B) HDMI
C) Ethernet
D) USB-A
Correct Answer: B) HDMI
Explanation: HDMI is the standard video output port for high-definition displays on modern computers.
Question 36
What is the main benefit of using a modular power supply in a desktop PC?
A) Lower energy consumption
B) Improved airflow and cable management
C) Higher wattage capacity
D) Faster data transfer speeds
Correct Answer: B) Improved airflow and cable management
Explanation: Modular power supplies allow users to connect only the cables they need, reducing clutter and improving airflow inside the case.
Question 37
What does the term “hot-swappable” refer to in computer hardware?
A) Devices that can be connected or removed without shutting down the system
B) Components that generate excessive heat
C) Drives that require cooling to function
D) Hardware that improves system performance when swapped
Correct Answer: A) Devices that can be connected or removed without shutting down the system
Explanation: Hot-swappable devices can be added or removed from a running system without requiring a reboot.
Question 38
What is the role of a northbridge in a computer system?
What is the role of a northbridge in a computer system?
A) Manage cooling of the CPU
B) Control communication between the CPU and high-speed components like RAM and GPUs
C) Handle network connections
D) Power the hard drives
Correct Answer: B) Control communication between the CPU and high-speed components like RAM and GPUs
Explanation: The northbridge manages communication between the CPU and faster components like RAM, GPUs, and PCIe devices.
Question 39
Which type of RAID requires at least three disks and provides both redundancy and improved read performance?
A) RAID 0
B) RAID 1
C) RAID 5
D) RAID 10
Correct Answer: C) RAID 5
Explanation: RAID 5 requires at least three disks and uses parity to provide redundancy while improving read performance through striping.
Question 40
What is the primary function of a thermal pad in a computer?
A) Increase CPU performance
B) Distribute heat away from components
C) Improve airflow inside the case
D) Provide electrical insulation
Correct Answer: B) Distribute heat away from components
Explanation: Thermal pads help dissipate heat from components like CPUs and GPUs by improving thermal conductivity between the component and the heat sink.
