1NetworkTwo or more devices connected together using a transmission medium and protocols to share data/resources
2Transmission MediaThe physical path between transmitter and receiver
3Serial Data TransmitionWhere bits are transmitted one after the other along a line
4Synchronous TransmissionWhere groups of bits are combined into frames and frames are sent continuously with or without data
5Asynchronous TransmissionWhere groups of bits are sent as independent units with start/stop flags
6Parallel Data TransmissionWhere more than one line/channel of bits are sent but each in series
7Baud RateThe rate at which the voltage of transmission can be changed
8Bit RateNumber of bits per second
9BandwidthA measure of range of frequencies that a transmission medium can use without a significant reduction in strength
10LatencyA measure of the time between sending and receiving
11Start BitA bit used to show the start of a frame
12Stop BitA bit used to show the end of a frame
13ProtocolSet of rules for communication and the exchange of data
14BasebandThe whole bandwidth is taken over to transmit the frame. Computers take it in turn and the network must manage collisions
15BroadbandThe bandwidth is split into multiple channels
