Bit rate
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.

Gigabit per second
A gigabit per second (Gbit/s or Gbps) is a
unit of
data transfer rate equal to 1,000
megabits per second or 1,000,000
kilobits per second or 1,000,000,000
bits per second.Examples of use:
Gigabit Ethernet, 1 Gbit/s
10 gigabit Ethernet, 10 Gbit/s
SCSI &
Fibre Channel hard drives
OC-24, a 1.244 Gbit/s
SONET data channel
OC-192, a 9.953 Gbit/s
SONET data channel, the fastest in current use

Pound sterling
The pound (symbol:
£; ISO code: GBP), divided into 100 pence, is the official
currency of the
United Kingdom and the
Crown dependencies. The official full name pound sterling (plural: pounds sterling) is used mainly in formal contexts and also when it is necessary to distinguish the currency used within the United Kingdom from
others that have the same name. The currency name — but not the names of its units — is sometimes abbreviated to just "sterling", particularly in the wholesale financial markets; so "payment accepted in sterling", but never "that costs five sterling". The abbreviations "ster." or "stg." are sometimes used. The term British pound is commonly used in less formal contexts, although it is not an official name of the currency. A common slang term is quid (plural quid).
