Multiple Choice Options
- A
semiconductor memory
- B✓ Correct Option
registers
- C
hard disk
- D
magnetic disk
Detailed Technical Solution & Explanation
Registers are high-speed semiconductor storage cells embedded directly inside the CPU/ALU architecture to hold immediate operands, memory pointers, and ALU status flags with zero bus latency.
Option Analysis:
•
Option A (semiconductor memory): Incorrect. Refers to external DRAM/SRAM main memory.
•
Option B (registers): Correct. Internal processor registers provide high-speed temporary storage for the ALU.
•
Option C (hard disk): Incorrect. Slow secondary magnetic storage.
•
Option D (magnetic disk): Incorrect.
