Band
A band is a range of frequencies in a range between two end points determined by general consent eg VHF, FM.

Bandwidth
A range of frequencies together making up a particular band.

Beam
The radiation from a satellite transponder. This may have a circular, elliptical or other shape, when looked at in diameter. The area, where this beam of radiation intersects with the Earth's surface is the reception area, also known as the footprint. The shape of the reception area depends on the elevation angle of the satellite as well as on the size of the broadcast angle of the transmitter antenna.

Bit
In computer sciences, the smallest elemental unit of data. A bit exists in only one of two possible states "Zero (or On)" or "One (or Off)". By adding together a number of bits you can create a digital "word", known as a byte.

Bouquet
A range of services marked collectively as a unit.

Branch connector
Passive construction element in a distribution system designed to divert part of the signals from the trunk line. The level of the branched-off signal is dependent on the branch damping of the branch connector.

Byte
In computer sciences, a group or packet of 8, 16, 32 etc, bits used in data transmission. Larger units are Kilobytes (1024 bytes) and Megabytes (1024 Kilobytes each). This deviates from the expected metric progression (1,000, 1,000,000 etc) because of the binary structure of computer data. Thus one Kilobyte is actually 210.
