FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A central processing unit (CPU), also called a central processor or main processor, is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions.

Detailed explanation-2: -The computer’s central processing unit (CPU) is the portion of a computer that retrieves and executes instructions. The CPU is essentially the brain of a CAD system. It consists of an arithmetic and logic unit (ALU), a control unit, and various registers.

Detailed explanation-3: -Just like humans, computers use a brain to process information. For a computer, the brain is the central processing unit (CPU). The CPU is the chip that executes all of the computer’s programs. It sits on the motherboard and communicates with all of the other hardware components inside the computer.

Detailed explanation-4: -The ALU carries out basic arithmetic and logic operations, and the control section determines the sequence of operations, including branch instructions that transfer control from one part of a program to another.
