- 1BandwidthA measure of the capacity of the channel down which data is being sent. It relates to the range of frequencies that are available on the carrier wave.
- 2Bit RateThe term used to describe the speed at which a particular transmission is occurring. It is measured in bits per second.
- 3Baud RateAnother term to describe the speed of a transmission. One baud represents one electronic state change per second. This could be a change in voltage, waveform, amplitude.
- 4Synchronous TransmissionData transmission where the two devices which are communicating have synchronized clocks in order to synchronize their transmissions.
- 5Asynchronous TransmissionData transmission where the two devices which are communicating do not have synchronized clocks. Instead a start bit and a stop bit are transmitted to determine the duration of the transmission.
- 6Latency 1-Propagation 2-Transmission 3-Processing1-The amount of time it takes for a logic gate within a circuit to transmit the data.
2-The amount of time it takes the transmission to pass through a particular communication medium.
3-The amount of time it takes data to pass around a network, depends on how many servers is must pass through. - 7Serial TransmissionData is sent and received data one bit at a time in sequence. This is transmitted one bit at a time.
- 8Parallel TransmissionData is transmitted several bits at a time using multiple wires.
- 9Carrier WaveThe waveform that carries the data, it is modulated.
- 10LatencyThe delay between the initiation of something and the end of that event. Significant time delays can occur due the large physical differences that signals must travel.
