Cards in this deck (17)
- 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
