Introduction to Boolean Algebra
Boolean algebra was developed by George Boole in 1854. He developed an algebra that was used for designing logic circuits in computer system. According to George Boole symbols can be used to represent the structure of logic in computer arithmetic. It also deals with law or rules that’s why it is also known as laws of Boolean algebra. It is used to simplify Boolean expressions which represent combinational logic circuits in computer system. The law of Boolean algebra is used to reduce and simplify a complex Boolean expression and reduce the number of gates required. The variables used in Boolean algebra have truth values such as true and false and logic values such as logic 0 and logic 1. It used with binary operation such as multiplication (.), addition (+) and unary operation (‘) . There are various types of laws of Boolean algebra.
