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 two typical components of a CPU include the following: The arithmetic logic unit (ALU), which performs arithmetic and logical operations. The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
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. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU).
