The central processor datapath contains a number of high-speed internal storage elements called:
Multiple Choice Options
- A
semiconductor memory
- B✓ Correct Option
registers
- C
hard disk
- D
magnetic disk
Detailed Technical Solution & Explanation
The Arithmetic Logic Unit (ALU) of a processor interacts directly with internal high-speed processor registers (such as the Accumulator, Data Registers, and Flag Registers) to stage operands and store immediate computation results in single-cycle access times.
Option Analysis:
•
Option A (semiconductor memory): Incorrect. Refers to main RAM, which is external to the ALU.
•
Option B (registers): Correct. Registers are the high-speed storage elements built directly within the CPU datapath.
•
Option C (hard disk): Incorrect. Secondary magnetic/flash storage located on I/O buses.
•
Option D (magnetic disk): Incorrect. Slow non-volatile mass storage.
