A) Ethernet
B) Telephone
C) Fiber
D) HDMI
Correct Answer: B) Telephone
Explanation: RJ11 connectors are used for telephone cables, typically for landline connections.
Question 06
What does RAID 5 provide?
A) Data striping without parity
B) Data striping with parity
C) Mirroring
D) Data striping and mirroring
Correct Answer: B) Data striping with parity
Explanation: RAID 5 provides data striping with parity, allowing for redundancy and fault tolerance.
Question 07
What is the maximum theoretical speed of a USB 3.1 Gen 1 connection?
A) 5 Gbps
B) 10 Gbps
C) 480 Mbps
D) 12 Mbps
Correct Answer: A) 5 Gbps
Explanation: USB 3.1 Gen 1 supports data transfer speeds of up to 5 Gbps.
Question 08
What kind of storage device is typically used for long-term, high-capacity storage?
- A) RAM
- B) SSD
- C) HDD
- D) ROM
Correct Answer: C) HDD
Explanation: Hard disk drives (HDDs) are typically used for long-term, high-capacity storage.
Question 09
What does ECC memory do?
- A) Improves data transfer speed
- B) Corrects single-bit memory errors
- C) Increases CPU clock speed
- D) Enhances video rendering
Correct Answer: B) Corrects single-bit memory errors
Explanation: ECC (Error Correcting Code) memory can detect and correct single-bit memory errors.
Question 10
What does “overclocking” a CPU involve?
- A) Increasing the voltage
- B) Running the CPU at a higher clock speed than the manufacturer specifies
- C) Decreasing the clock speed to save power
- D) Shutting down the CPU when it overheats
Correct Answer: B) Running the CPU at a higher clock speed than the manufacturer specifies
Explanation: Overclocking increases the CPU's clock speed to boost performance, often at the expense of stability and temperature control.
Question 11
Which component is responsible for rendering graphics in a computer system?
A) CPU
B) GPU
C) RAM
D) NIC
Correct Answer: B) SATA
Explanation: SATA power connectors are commonly used to supply power to hard drives and SSDs.

What type of power supply connector is typically used for hard drives and SSDs?
A) Molex
B) SATA
C) PCIe
D) USB
Correct Answer: B) SATA
Explanation: SATA power connectors are commonly used to supply power to hard drives and SSDs.
Question 13
Which of the following is a benefit of solid-state drives (SSDs) over hard disk drives (HDDs)?
A) Lower capacity
B) Higher durability and faster read/write speeds
C) Higher power consumption
D) Slower data access
Correct Answer: B) Higher durability and faster read/write speeds
Explanation: SSDs are faster and more durable than HDDs because they have no moving parts.
Question 14
What type of memory is non-volatile and retains data when the computer is powered off?
A) RAM
B) ROM
C) CPU cache
D) VRAM
Correct Answer: B) ROM
Explanation: ROM (Read-Only Memory) retains data even when the computer is powered off.
Question 15
What kind of storage device is typically used in modern mobile devices?
A) HDD
B) SSD
C) SD card
D) Floppy disk
Correct Answer: C) SD card
Explanation: SD cards are commonly used for additional storage in mobile devices due to their small size and portability.
Question 16
What is the purpose of a heat sink in a computer system?
A) To increase CPU speed
B) To cool down components
C) To store extra data
D) To protect the power supply
Correct Answer: B) To cool down components
Explanation: A heat sink dissipates heat from components, such as the CPU, to prevent overheating.
Question 17
What is the function of the BIOS in a computer system?
A) Store user files
B) Control hardware initialization and provide runtime services
C) Improve GPU performance
D) Increase network speed
Correct Answer: B) Control hardware initialization and provide runtime services
