WGU D772 Objective Assessment – MCQs (1–50)
1. What is the main function of the CPU?
A. Store data permanently
B. Execute instructions and perform calculations
C. Manage network traffic
D. Display graphics
Answer: B
Rationale: The CPU is the central processing unit, responsible for executing instructions and
performing calculations.
2. Which of the following best describes RAM?
A. Permanent storage
B. Volatile memory used for temporary data and program execution
, Page 2 of 90
C. External storage
D. Network memory
Answer: B
Rationale: RAM (Random Access Memory) is temporary, volatile memory used while programs
run.
3. What does the instruction cycle include?
A. Fetch, decode, execute, and store
B. Read and write only
C. Booting the computer
D. Installing software
Answer: A
Rationale: The instruction cycle is the fetch-decode-execute-store sequence.
4. Which of the following best describes a cache memory?
A. Long-term storage
B. Small, high-speed memory located close to the CPU
C. Backup storage
D. Hard disk partition
, Page 3 of 90
Answer: B
Rationale: Cache memory reduces access time to frequently used data.
5. What is the purpose of a register in the CPU?
A. Store data temporarily for immediate processing
B. Manage network connections
C. Permanent data storage
D. Run user applications
Answer: A
Rationale: Registers hold data and instructions temporarily for quick CPU access.
6. Which of the following is an example of volatile memory?
A. ROM
B. RAM
C. Hard drive
D. Flash storage
Answer: B
Rationale: RAM loses data when the system is powered off.

7. What is the difference between RISC and CISC architectures?
A. RISC uses fewer, simpler instructions; CISC uses more complex instructions
B. RISC is slower than CISC
C. CISC uses only 32-bit instructions
D. There is no difference
Answer: A
Rationale: RISC (Reduced Instruction Set Computer) uses simpler instructions, while CISC
(Complex Instruction Set Computer) has more complex instructions per cycle.
8. Which of the following is a primary storage device?
A. RAM
B. Hard disk
C. USB drive
D. Optical drive
Answer: A
Rationale: Primary storage is directly accessible by the CPU, such as RAM.
