Boolean algebra is a shorthand notation for a system of logic introduced by George Boole.

The logic deals with a set of statements (represented by ) and an outcome (output).

Boolean will typically involve two variables ( and Y) and an output variable ().

Boolean variables have two possible values: or false. This is why Boolean algebra is good for representing computer logic as computers use a system that only uses two states and 0.

A Table is used to show the results of applying a function to all possible combinations of inputs.

Typical logical are AND, OR and NOT.

Function: The output is TRUE if EITHER or BOTH inputs are TRUE.

Function: The output is TRUE if BOTH/ALL inputs are TRUE.

Function: The output is the inverse of the input (so if input is TRUE, output will be FALSE).

Logic are electronic that can perform Boolean functions. Function: The output is the inverse of the input (so if input is TRUE, output will be FALSE).

Logic Gates are electronic that can perform Boolean functions.
