BPS - Bits per Second<br />

BPSK - Binary Phase Shift Keying;<br />

a type of constant phase modulation.<br />

Bridge - A device that connects two<br />

or more physical networks and<br />

forwards packets between them.<br />

Bridges can usually be made to<br />

filter packets, that is, to forward<br />

only certain traffic. Bridges do not<br />

make traffic routing decisions.<br />

Broadband - Refers to networks<br />

capable of delivery high bandwidth<br />

typically at speeds greater<br />

than 1 Mbps. In the digital domain,<br />

all content is digitized and hence<br />

the bandwidth is usually measured<br />

in bits-per-second (BPS).<br />

Broadcast - A delivery system in<br />

which all receivers have the same<br />

content delivered to them in a<br />

single transmission stream.<br />

Burst Mode - A method of data<br />

transmission in which data is<br />

collected and then sent in a single<br />

high-speed transmission.<br />

Byte - One byte of digital video<br />

information is a packet of bits,<br />

usually but not always eight. One<br />

thousand bytes is one kilobyte (kb)<br />

and one million bytes is one<br />

megabyte (MB).<br />

Caching - A form of data replication<br />

in which information learned<br />

during a previous transaction is<br />

used to process later transactions.<br />

C-Band - The frequency band<br />

between 4 and 8 GHz with the 6<br />

and 4 GHz band being used for<br />

satellite communications.<br />

CBR - Constant Bit Rate (CBR): A<br />

Quality of Service (QoS) class<br />

defined by the ATM Forum for ATM<br />

networks. CBR is used for connections<br />

that depend on precise<br />

clocking to ensure data delivery<br />

with constant timing<br />

CER - Channel Error Rate - a<br />

measure of transmission errors that<br />

is calculated from error correction<br />

coding<br />

CDMA - Code division multiple<br />

access. Refers to a multiple-access<br />

scheme where stations use spreadspectrum<br />

modulations and orthogonal<br />

codes to avoid interfering<br />

with one another<br />

CIR - Committed Information Rate;<br />

the rate at which the network<br />

agrees to transfer information<br />

under normal conditions. The rate<br />

is averaged over a minimum<br />

increment of time.<br />

Cookie - A piece of information<br />

issued by the server to the client,<br />

stored by the client, and later sent<br />

back to the server. Cookies allow<br />

information to be saved in the<br />

client, instead of the server having<br />

to allocate resources for doing<br />

that.<br />

CRC - Cyclic Redundancy Check ;<br />

the value obtained by applying a<br />

mathematical function to the bits<br />

in a frame and appended to the<br />

frame. The CRC is recalculated<br />

when the frame is received. If the<br />

result differs from the appended<br />

value, the frame is discarded.<br />

CSU - Cyclic Redundancy Check ;<br />

the value obtained by applying a<br />

mathematical function to the bits<br />

in a frame and appended to the<br />

frame. The CRC is recalculated<br />

when the frame is received. If the<br />

result differs from the appended<br />

value, the frame is discarded.<br />

DAMA - Demand Assigned Multiple<br />

Access - a highly efficient technique<br />

for sharing satellite bandwidth<br />

among many users.<br />

dB Decibel. - A unit of signal<br />

measurement that expresses a ratio<br />

between two electrical signals or<br />

levels logarithmically.<br />

dBW - An expression of power in dB<br />

relative to one watt.<br />

DCE - Data Circuit-terminating<br />

Equipment (DCE): Equipment<br />

required to connect a DTE (data<br />

terminal equipment) to a line or to<br />

a network.<br />

Demodulator - Equipment that<br />

converts the RF signal from the<br />

carrier into baseband signals<br />

(video, audio, or data) for further<br />

processing or amplification.<br />

DES - Data Encryption Standard<br />

(DES): A symmetric encryption<br />
