A student notices that arithmetic results appear instantly, but loading data from main memory is slower. Which CPU feature primarily reduces this delay by keeping frequently used data close to the processor?
Cache Memory
Cache memory is a small, very fast memory placed between the CPU and the main memory (RAM).
It stores frequently used instructions and data close to the processor, so the CPU can access them much faster than fetching from the slower main memory, reducing the delay.
The instruction set defines the commands a CPU understands, the address decoder selects memory locations, and the CPU fan handles cooling, so none of these reduces the memory access delay.
Hence, the feature that reduces this delay is cache memory.
