In this Paper we have discussed different types of logic gates (AND,OR,NOT,NAND,NOR,XOR,XNOR) and corresponding logic tables. The base of any digital computer system are logic gates or circuits which performs logical operations on chunks of information represented digitally. Logic gates work on the basis of binary digits 0 and 1.Any intelligent system with the abilities to take decision comprises of simple logic gates. This paper is an attempt to bring forth the application of digital logic gates in day to day life with some real time applications as well like burglar alarm and security system. Through the study of no. of physical sytems e.g. mechanical, optical, electrical, thermal, biological systems it can be said that modeling of any such system can be done logically with the help of a Boolean expression. Accordingly such a system can be studied mathematically. This paper is a generic effort in understanding the Boolean mathematics behind the physical system around.

AND, OR, NOT, NAND, NOR, XOR, XNOR Gates.
