Write short notes on Logical OR operator.

Logical OR is a Boolean operator that returns True, if at least one of the operands is true. It only returns False when both operands are false and is used for conditional evaluations. This operator results in logical addition of two or more binary valued quantities. It is denoted by a plus ( + ) sign. The output of logical OR is 0 only when all the operands are 0, otherwise the output is 1.
