Correct answer: B
Answer: Register Memory is the fastest.
Why: Registers are located inside the CPU and are implemented with flip-flops, allowing access in a single CPU cycle and the lowest latency.
Relative speeds: Register memory (fastest) → Cache memory → Main memory (RAM) → Secondary storage (slowest). Capacity increases in the opposite direction.
Typical uses: Registers hold operands and intermediate results for the CPU; cache stores recently or frequently used data to reduce accesses to RAM; RAM holds running programs and data; secondary storage holds persistent files.
Tip: When asked which memory is fastest, choose the memory that is physically closest to the CPU core and smallest in size — that is register memory.
