Quizplus · Accepted Answer

Registers are a small set of high-speed memory locations that are part of the CPU. They hold instructions and data that are currently being executed by the CPU. They are used to temporarily store values before they are used in calculations or moved to or from main memory. Main memory (A) is a larger pool of memory used to store programs and data while they are not being actively used by the CPU. The ALU (C) or Arithmetic Logic Unit is a component of the CPU that performs arithmetic and logical operations. The CPU (D) is the central processing unit that controls all the processing activities of the computer.
