Question

5 WELL DEFINED CHARACTERISTICS OF A.LU AND C.U

Answer 1

Difference Between ALU and CU

ALU:

ALU stands for Arithmetic Logic Unit. It is a very essential part of the CPU. It performs all the basic arithmetic (addition, subtraction, multiplication, and division) operations and logical operations.

The ALU typically designed in such a way that it has direct input and output access to the random access memory (RAM). In modern computers, the ALU is itself is divided into two categories:

1. Arithmetic Unit (AU)
2. Logic Unit (LU)

CU:

CU stands for Control Unit. It is one of the fundamental parts of the CPU. The main work of the CU is to tell the most efficient method to work. It guides all the related operations to the individual parts of the processor. Some basic operation performed by it includes taking guidelines, controlling sequential execution, managing information stream in the correct course, directing and observing the time needed amid the preparing and taking care of different functions, etc.

It controls the operations of the processor. It informs the ALU, I/O devices, and the RAM how to respond to the command that has been sent to the processor. A control unit directs the system and executes instructions entered by the user.
