In computing, bit specification may mean:
- Computer hardware or software capabilities or design features expressed in terms of bit counts. Higher bit specification (e.g. 16-bit vs. 8-bit) usually indicates better performance. Examples:
- Specification or datasheet where the meaning of individual bits in a larger, for example byte-length, message is described. Bit specifications are often required to document low-level device control or data transmission protocols. See bit manipulation.
