MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The Central Processing Unit (CPU) is also known as the microprocessor or processor. The processor contains three sections called the Arithmetic Logic Unit (ALU), the Control Unit and Registers. Control unit: The Control Unit makes decisions and sends the appropriate signal down its lines to other parts of the computer.

Detailed explanation-2: -The Control unit, arithmetic and logic unit and memory unit of a computer constitutes CPU (Central processing unit).

Detailed explanation-3: -What is an arithmetic-logic unit (ALU)? An arithmetic-logic unit is the part of a central processing unit that carries out arithmetic and logic operations on the operands in computer instruction words.

Detailed explanation-4: -A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.

Detailed explanation-5: -The CPU control unit is a component of the computer’s CPU (central processing unit) that directs the processor’s operation. John von Neumann included it in his Von Neumann Architecture.
