Answer Key Distribution: 25 A · 25 B · 25 C · 25 D
, Section 1: Advanced Computer Hardware - Processors, Memory Hierarchy, and
Storage Technologies
Q1: CPU pipelining improves performance by:
A. Overlapping the execution of multiple instructions [CORRECT]
B. Increasing the clock speed only
C. Adding more RAM
D. Reducing the cache
Correct Answer: A
Rationale: Pipelining overlaps instruction execution to improve throughput. The other options are incorrect.
Q2: A multicore CPU:
A. Contains multiple processing cores on one chip [CORRECT]
B. Has a single core
C. Only increases storage
D. Is only for servers
Correct Answer: A
Rationale: A multicore CPU has multiple cores on one chip. The other options are incorrect.
Q3: The memory hierarchy, from fastest to slowest, is generally:
A. RAM, cache, registers, storage
B. Registers, cache, RAM, secondary storage [CORRECT]
C. Storage, RAM, cache, registers
D. Cache, storage, RAM, registers
Correct Answer: B
Rationale: Registers are fastest, then cache, then RAM, then secondary storage. The other options are incorrect.
Q4: Cache memory is:
A. A type of hard drive
B. RAM that is always full
C. A peripheral
D. A small, fast memory close to the CPU [CORRECT]
Correct Answer: D
Rationale: Cache is small, fast memory near the CPU. The other options are incorrect.
Q5: Virtual memory uses:
A. Only RAM
B. Disk space to extend the apparent amount of RAM [CORRECT]
C. Only the CPU
D. Only the cache
Correct Answer: B
Rationale: Virtual memory uses disk space to extend apparent RAM. The other options are incorrect.
Q6: Which is an advantage of an SSD over an HDD?
A. Larger physical size
B. Higher power use
C. Slower performance
D. Faster access and no moving parts [CORRECT]
Correct Answer: D
Rationale: SSDs are faster and have no moving parts. The other options are incorrect.
Q7: RAID 1 (mirroring) provides:
A. Redundancy by duplicating data across two disks [CORRECT]
ITE 152 Exam 3 - 2026/2027 Page 2
, B. Faster writes only
C. No redundancy
D. Only more storage without redundancy
Correct Answer: A
Rationale: RAID 1 mirrors data for redundancy. The other options are incorrect.
Q8: Which interface is commonly used to connect modern external devices?
A. SATA only
B. The CPU socket
C. The RAM slot
D. USB [CORRECT]
Correct Answer: D
Rationale: USB is a common external interface. The other options are internal or not interfaces.
Q9: Thunderbolt is:
A. A type of RAM
B. A high-speed interface that can carry data, video, and power [CORRECT]
C. A CPU
D. A printer
Correct Answer: B
Rationale: Thunderbolt is a high-speed interface carrying data, video, and power. The other options are incorrect.
Q10: HDMI is primarily used to:
A. Transmit audio and video to a display [CORRECT]
B. Store data
C. Cool the CPU
D. Provide power
Correct Answer: A
Rationale: HDMI transmits audio/video to a display. The other options are incorrect.
Q11: The 'clock speed' of a CPU is measured in:
A. GHz (gigahertz) [CORRECT]
B. GB (gigabytes)
C. Mbps
D. Watts
Correct Answer: A
Rationale: CPU clock speed is measured in gigahertz. The other options measure other things.
Q12: Which is an example of a volatile memory that loses data on power-off?
A. ROM
B. An SSD
C. RAM [CORRECT]
D. An HDD
Correct Answer: C
Rationale: RAM is volatile. ROM, SSDs, and HDDs are non-volatile.
Section 2: Operating Systems & Virtualization - OS Functions, File Systems, and
Virtual Machines
Q13: Process management in an OS involves:
A. Managing the execution and scheduling of processes [CORRECT]
B. Only storing files
