1BUS TOPOLOGYComputer network in which a "bus" connects all the devices together through a common cable.
2CABLECopper wire (usually coaxial and twister pair) and fibre (fibre optic cable-made from glass). Cables allowed for the connection of computers over a network.
3CHECK DIGITExtra digit added to numerical data that is used to check data integrity after input, transmission, storage an processing.
4DATA INTEGRITYThe accuracy of databafter input, transmission, storage or processing.
5CHECK SUMError-detecting procedure that generates a sum from the digits f a number.
6DATA PACKETPortion of a message that is transmitted through a network. Contains data such as check digits and destination address.
7GATEWAYLink that resides between computer networks and is responsible for converting data passing through into the appropriate format so it can be understood by the receiving network.
8HANDSHAKINGExchange of predetermined signals to signify that a connection has been established between two systems.
9HUBNetwork connection point for devices. Data arriving at a hub is copied and send to all the devices on the network.
10ISDNInternational communications standard that allows for the transmission of audio/video and other data over digital telephone lines.
11LANComputer network where all the connected computers are within a limited geographical area ( ex. A home, school etc.) Connection between the computers may be through cables and/or microwave transmission
12MICROWAVE TRANSMISSIONElectronic communications without the need for cables.
13MODEMElectronic equipment that converts computer digital signals into audio signals and back. The audio signals are transmitted over telephone lines, which allows for distant communication.
14NETWORKComputer systems that are interconnected and can share resources and data.
15PACKETGroup of bits. May include control signals, error control bits, coded information, as well as the destination for the data.
16PACKET SWITCHINGNetwork communication method that creates and transmits small units of data, called packets, through the network, independently of the overall message.
17NETWORKINGMaking use of a network
