bit manipulation

[′bit mə‚nip·yə′lā‚shən]
(computer science)
Changing bits from one state to the other, usually to influence the operation of a computer program. Also known as bit flipping.

bit manipulation

Processing individual bits within a byte. Bit-level manipulation is very low-level programming, often done in graphics and systems programming. See bit flipping.
