In
telecommunications and
computing, bitrate (sometimes written bit rate, data rate or as a
variable R or fb) is the number of
bits that are conveyed or processed per unit of time. Bit rate is synonymous to data rate and
digital bandwidth. The bit rate is quantified using the 'bit per second' (bit/s or bps) unit, often in conjunction with a
SI prefix such as
kilo- (kbit/s or kbps),
mega- (Mbit/s or Mbps),
giga- (Gbit/s or Gbps) or
tera- (Tbit/s or Tbps). In digital communication systems, the gross bitrate, raw bitrate,
data signaling rate or
line rate is the total number of physically transferred bits per second over a communication link, including useful data as well as protocol overhead.
