(computing) the rate of flow of binary digits in a digital data-processing system, usually expressed as the number of bits per second
communications, digital signal processing
(Or “bitrate”) A data rate expressed in bits per second. This is a similar to baud but the latter is more applicable to channels with more than two states.
The common units of bit rate are kilobits per second (Kbps) and megabits per second (Mbps). In data rates, the multipliers “k”, “M”, etc. stand for powers of 1000 not powers of 1024.
The term is also commonly used when discussing digital sampling and sample rates. For example, the MP3 audio compaction algorithm is often set to ouput files with a bitrate of 120 kbps. This means that the file contains an average of 120 kilobits for each second of audio (900 KB per minute). This compares with CD audio which is encoded at 44100 16-bit stereo samples per second or 1408 kbps.
bit rot jargon A hypothetical disease the existence of which has been deduced from the observation that unused programs or features will often stop working after sufficient time has passed, even if “nothing has changed”. The theory explains that bits decay as if they were radioactive. As time passes, the contents of a file or […]
adjective (computing) (of central processing units) able to be built up in sections to form complete central processing units with various word lengths architecture A technique for constructing a processor from modules, each of which processes one bit-field or “slice” of an operand. Bit slice processors usually consist of an ALU of 1, 2, 4 […]
brace (def 3). noun the handle or stock of a tool into which a drilling bit is fixed
bit gauge. a device for stopping a bit when it has reached a desired depth.
