| Question | Answer |
| Network | Two or more devices connected together using a transmission medium and protocols to share data/resources |
| Transmission Media | The physical path between transmitter and receiver |
| Serial Data Transmition | Where bits are transmitted one after the other along a line |
| Synchronous Transmission | Where groups of bits are combined into frames and frames are sent continuously with or without data |
| Asynchronous Transmission | Where groups of bits are sent as independent units with start/stop flags |
| Parallel Data Transmission | Where more than one line/channel of bits are sent but each in series |
| Baud Rate | The rate at which the voltage of transmission can be changed |
| Bit Rate | Number of bits per second |
| Bandwidth | A measure of range of frequencies that a transmission medium can use without a significant reduction in strength |
| Latency | A measure of the time between sending and receiving |
| Start Bit | A bit used to show the start of a frame |
| Stop Bit | A bit used to show the end of a frame |
| Protocol | Set of rules for communication and the exchange of data |
| Baseband | The whole bandwidth is taken over to transmit the frame. Computers take it in turn and the network must manage collisions |
| Broadband | The bandwidth is split into multiple channels |
