Or

Logical OR has the meaning you would expect from its name. OR is usually denoted by the symbol ∨. \( x \vee y \) is True if either The value of \( x \) or \( y \) is True. Its table looks like the addition table, with just one twist.

    ∨|  0   1
  ---+-------
    0|  0   1
    1|  1   1

OR applied to two bytes is applied bit by bit.

Example

Here is the OR of two bytes. As with AND, we aren't necessarily interested in the numerical values.

      01100100
    ∨ 00111101
  ------------
      01111101
