# Boolean Algebra Introduction

**Boolean algebra** is the **algebra of logic**.

Boolean algebra has long been used in designing the electronic circuitary of computers.

Boolean algebra is simple and easy to understand. It is somewhat like making logical decisions in our daily life.

Boolean algebraoperates on binary values 0 and 1.The output processed is also in binary number.

0 can also be written as False

1 can also be written as True.

These are used as an alternate.

So don't get confused if you see True and False as input and output. It is same as 0 and 1.

Boolean algebra provides ways to do different operations using which different

logic gatesof computer is designed.

So basically based on the operation performed there are basically three types of logic gates

**Basic Logic gates**

- AND gates
- OR gates
- NOT gates

**Universal Logic gates**

- NAND gates
- NOR gates

**Exclusive Logic gates**

- XOR gates
- XNOR gates

The input for these gates and output produced is represented as **Truth table**.

We will learn in details about each one of them in upcoming chapters of this * boolean algebra tutorial*.
