OR gate

OR gate truth table
Input		Output
A	B	A OR B
0	0	0
0	1	1
1	0	1
1	1	1

In digital electronics, an OR gate is a logic gate which produces an output of true when any of its inputs are true. A LOW (0) output results when all of the inputs to the gate are LOW; if any of the inputs are HIGH (1), a high output results.

Logic

A two-input OR gate can be expressed in Boolean logic as $A+B$ or $A\lor B$.
