Which type of computer memory provides the fastest read and write access times directly to the arithmetic logic unit?
Answer and explanation
Correct answer: C. CPU registers
- Step 1: Registers are located inside the processor core and operate at the processor's full clock frequency with sub-nanosecond access. Step 2. They hold immediate operands and instruction addresses directly for execution circuits. Answer: CPU registers. Why not the others: L1 cache ranks second in speed; SRAM is used for external cache; DRAM is main system memory with higher latency.
