| CABLE | Copper wire (usually coaxial and twister pair) and fibre (fibre optic cable-made from glass). Cables allowed for the connection of computers over a network. |
| CHECK DIGIT | Extra digit added to numerical data that is used to check data integrity after input, transmission, storage an processing. |
| DATA INTEGRITY | The accuracy of databafter input, transmission, storage or processing. |
| CHECK SUM | Error-detecting procedure that generates a sum from the digits f a number. |
| DATA PACKET | Portion of a message that is transmitted through a network. Contains data such as check digits and destination address. |

| MICROWAVE TRANSMISSION | Electronic communications without the need for cables. |
| MODEM | Electronic equipment that converts computer digital signals into audio signals and back. The audio signals are transmitted over telephone lines, which allows for distant communication. |
| NETWORK | Computer systems that are interconnected and can share resources and data. |
| PACKET | Group of bits. May include control signals, error control bits, coded information, as well as the destination for the data. |
| PACKET SWITCHING | Network communication method that creates and transmits small units of data, called packets, through the network, independently of the overall message. |
| NETWORKING | Making use of a network |
