Detailed explanation-1: -A CPU consists of two parts – Arithmetic Logic Unit (ALU) which performs arithmetic operations like addition, multiplication, division, subtraction and logical comparisons like greater than, less than, equal to, etc. and Control Unit (CU) which directs and co-ordinates most of the operations in the computer.
Detailed explanation-2: -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.
Detailed explanation-3: -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: -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. The CPU is often simply referred to as the processor. The ALU performs arithmetic operations, logic operations, and related operations, according to the program instructions.
Detailed explanation-5: -There are 2 parts of the CPU: The ALU and Control Unit. The Arithmetic Logic Unit (ALU) performs arithmetic operations (such as addition and subtraction) and logical operations (such as comparing two values). The Control Unit deciphers and carries out instructions.
