What Does Bitwise Operator Mean?
A bitwise operator is an operator used to perform bitwise operations on bit patterns or binary numerals that involve the manipulation of individual bits.
Techopedia Explains Bitwise Operator
Unlike common logical operators (like +, -, *), which work with bytes or groups of bytes, bitwise operators can check or set each of the individual bits within a byte. Bitwise operators never cause overflow because the result produced after the bitwise operation is within the range of possible values for the numeric type involved.
