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: Color depth Computer bus size Processor register size Sound quality 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 When using uppercase, BIT Specification may refer to the requirements of a Built in Test for a machine.
