Answer 1

Answer:

A. Address

A memory address is a reference to a specific memory location used at various levels by software and hardware. Register memory is the smallest and fastest memory in a computer. It temporarily holds frequently used data, instructions, and memory address that is to be used by the CPU. Memory address register (MAR) is the CPU register that either stores the memory address from which data will be fetched to the CPU, or the address to which data will be sent and stored.
