## INTRODUCTION

WHAT IS ARITHMETIC AND LOGIC UNIT | COMPONENTS AND FUNTION – The central processing unit is the brain of the computer!

It consists mainly of two components. One controller and the other arithmetic logic unit!

This is a very important part of computers.

## ARITHMETIC AND LOGIC UNIT

Just from its name, it will be noticed that this element must have something to do with mathematics and logic.

All the mathematical operations like multiplication, division, addition, subtraction, etc. are done in this unit.

Apart from this, the actions that depend on logic also happen through this factor. In such actions, one number is compared to another.

The given two numbers may be the same, one may be smaller or larger than the other, or the two numbers may be unequal.

These and many more are investigated mainly in the arithmetic logic unit.

### COMPONENTS

An important component of the arithmetic logic unit is the accumulator!

This is a special kind of electric field. One of the two given numbers is always brought into the accumulator and the required mathematical operations are performed in the same place along with the other number.

The answer to this action is then stored in the form of a new number, probably again in the accumulator itself.

The arithmetic logic unit has many other electrons to store numbers beside the accumulator, they are called registers.

### FUNCTION OF ARITHMETIC AND LOGIC UNIT

The controller instructs the component, the arithmetic logic unit, which of the arithmetic operations to perform addition, subtraction, etc. And at the same time provides him with the numbers he needs.

The arithmetic logic unit works a bit like a simple calculator.

The only difference is that the calculator gives the calculator instructions on what to do by pressing the appropriate buttons, while the controller in the computer provides the same component to the arithmetic logic unit.
