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 algebra operates 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 gates of computer is designed.
So basically based on the operation performed there are basically three types of logic gates
Basic Logic gates
Universal Logic gates
Exclusive Logic gates
The input for these gates and output produced is represented as Truth table.
In next chapter we study about Truth table in details.
