What is the purpose of cache memory? How sequential access differs from direct access? [5]
Cache memory is a small, high-speed memory placed between the CPU and the main memory (RAM) in the memory hierarchy. 1. Speed Bridging: The CPU operates much faster than RAM (CPU registers: 1-2 ns, RAM: ~60 ns). Cache memory (speed: 2-10 ns) bridges this speed gap so the CPU does not have to wait...
