Arithmetic and Logical Unit (ALU)
The Arithmetic and Logical Unit (ALU) of the Central Processing Unit (CPU) acts as one of the prime components of the computer. It is the place where actual execution of instruction takes place during the processing of operations. The Arithmetic and Logical Unit (ALU) actually performs the arithmetic operations such as addition, subtraction and multiplication and logical operations such as OR, AND, NOT etc.
Control Unit (CU)
All the computer resources are managed from the control unit. The control unit controls the flow of data through the CPU and to and from other devices. The control unit is the logical hub of the computer. Many instructions carried out by the control unit involve simply moving data from one place to another from memory to storage, from memory to the printers and so forth.
Memory Unit (MU)
The memory unit is the integral memory system that is used to hold data and instructions for the immediate access use by the computer's ALU. It operates at the highest speed and can be directly accessed by the CPU.
