Boolean algebra is an algebra that deals with Boolean values((TRUE and FALSE) . Everyday we have to make logic decisions: “Should I carry the book or not?” , “Should I watch TV or not?” etc. Each question will have two answers yes or no, true or false. In Boolean Algebra we use 1 for true and 0 for false which are known as truth values.

Truth table:

A truth table is composed of one column for each input variable (for example, A and B), and onefinal column for all of the possible results of the logical operation that the table is meant to represent (forexample, A XOR B). Each row of the truth table therefore contains one possible configuration of the input variables (for instance, A = true B = false), and the result of the operation for those values. Logical Operators: In Algebraic function e use +,-,*,/ operator but in case of Logical Function or Compound statement we use AND,OR & NOT operator.

Example: He prefers Computer Science NOT IP.

There are three Basic Logical Operator:

1. NOT

2. OR

3. AND
