What is a Kilobit?
Definition
A kilobit (kb or kbit) is a multiple of the bit unit for digital information or computer storage. The prefix kilo- (symbol k) is defined in the International System of Units (SI) as a multiplier of 103 (1 thousand). Therefore, 1 kilobit = 1000 bits.
History
The use of the "kilo" prefix for bits emerged alongside its use for bytes as computer systems grew. While "kilobyte" was often ambiguously used for 1024 bytes (correctly kibibyte), the term "kilobit" (especially in data transmission contexts) more consistently adhered to the SI standard definition of 1000 bits. The introduction of binary prefixes like 'kibi-' (for kibibit, Kib) aimed to resolve such ambiguities.
Common Uses
Kilobits are frequently used in specific contexts:
- Measuring data transfer rates (e.g., internet connection speeds in kbps - kilobits per second, or Mbps - megabits per second).
- Quantifying the capacity of certain types of serial communication channels.
- Specifying audio or video streaming bitrates (e.g., a 128 kbps MP3 audio file).
