Parts of Computer
Central processing unit
A central processing unit (CPU), also referred to as a central processor unit,[1] is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system
Two typical components of a CPU are the arithmetic logic unit(ALU), which performs arithmetic and logical operations, and the control unit (CU)
Control Unit
The control unit of the CPU contains circuitry that uses electrical signals to direct the entire computer system to carry out stored program instructions. The control unit does not execute program instructions; rather, it directs other parts of the system to do so. The control unit must communicate with both the arithmetic/logic unit and memory.
ALU
In computing, an arithmetic and logic unit (ALU) is a digital circuit that performs arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit of a computer
Registers
A processor register is a small amount of storage available as part of a CPU or other digital processor.
