Deference Between Arithmetic Logic Unit (ALU) and Control Unit(CU)

What is arithmetic logic unit(ALU)?

Arithmetic logic unit(ALU) is one kind of digital circuit which perform all the arithmetic and logical operation of a computer.It is the main component of Central Processing unit.Control Unit helps to transfer the data from register to register and arithmetic logic unit(ALU) Perform the logical operation by using operators.

We know basic arithmetic operations are Addition, Subtraction, Multiplication and Division. On the other hand, basic logical operations are AND , OR, NOT. arithmetic logic unit(ALU) performs these types of things.

What is Control Unit (CU)?

Control Unit (CU) is another main component in computer that means the central processing unit (CPU). Control unit does the other things except from arithmetic and logic operations.Mainly Control Unit handles the data movement between the sub units.

Central Processing Unit (CPU) and Graphics Processing Unit (GPU heavily uses Control Unit(CU). Control Units works as a medium between ALU and main memory.

Differences between Arithmetic Logic Unit (ALU) and Control Unit(CU):

Arithmetic Logic Unit (ALU)	Control Unit(CU)
ALU perform all the arithmetic and logical operation.	Control Unit handles the data movement between the sub units.
ALU Perform the logical operation by using operators	CU handles the data movement between memory and registers.
ALU performs all kinds of mathematical operations.	ALU) Perform the logical operation by using operators
