Question

3. The CPU consists of unit and unit.​

Answer 1

The central processing unit (CPU) consists of Control unit, arithmetic-logic unit and primary storage.

All computers, large and small, must have a central processing unit. As Figure 1 shows, the central processing unit consists of two parts: The control unit and the arithmetic/logic unit. ... The CPU interacts closely with primary storage, or main memory, referring to it for both instructions and data.

 The computer does its primary work in a part of the machine we cannot see, a control center that converts data input to information output. This control center, called the central processing unit (CPU), is a highly complex, extensive set of electronic circuitry that executes stored program instructions.

An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs.

The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's it is control all part of processor instructions

hehehe XD

i know it's too long but i hope it helps XD
