Bit per Second (bps)
Bits per second (bit/s or bps) is the basic unit of data transfer rate. Serial links such as UART run at 9600 or 115,200 bit/s.
Symbol: bps
Quantity: data transfer rate (bandwidth)
SI relation: The bit per second is the basic unit of data rate. It is not an SI unit, but decimal prefixes give kbit/s, Mbit/s and Gbit/s in steps of 1000.
Derivation: One bit transferred each second.
Exact: yes, by definition
Typical uses
- Serial ports and modems (baud-like rates)
- Base unit for kbps, Mbps and Gbps
