Detailed explanation-1: -Answer. A typical computer has 3 types of memory: Cache memory, Random Access Memory (RAM), and virtual memory. Cache is the fastest and most expensive, RAM is slower and less expensive, and virtual memory is the slowest and least expensive type.
Detailed explanation-2: -Answer-The register memory unit has lowest access time. A tiny amount of data between 32 and 64 bits is stored in registers. The quantity and size (number of bits) of registers a CPU has built-in determine its speed.
Detailed explanation-3: -THE SECONDARY MEMORY HAS THE LONGEST ACCESS TIME. THIS MEMORY CANNOT PRECEDED IN CPU DIRECTLY BUT IT SHOULD BE TRANSFERRED FIRST TO RAM.
Detailed explanation-4: -A program’s instructions and data are initially stored at virtual addresses, and once the program is executed, those addresses are turned into actual memory addresses. One downside to virtual memory is that it can slow a computer because data must be mapped between the virtual and physical memory.
