| Question | Answer |
| bus topology | Computer network in which a "bus" connects all the devices together through a common cable |
| cable | Copper wire (usually coaxial and twisted pair) and fibre (fibre optic cable-made from glass). Cables allow 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 and processing. |
| data integrity | The accuracy of data after input, transmission, storage or processing. |
| check sum | Error-detecting procedure that generates a sum from the digits of a number. |
| data packet | Portion of a message that is transmitted through a network. Contains data such as check digits and destination address. |
| gateway | Link 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. |
| handshaking | Exchange of predetermined signal to signify that a connection has been established between two systems. |
| hub | Network connection point for devices. Data arriving at a hub is copied and send to all the devices on the network. |
| ISDN (integrated services digital network) | International communications standard that allows for the transmission of audio/video and other data over digital telephone lines. |
| local area network | Computer network where all the connected computers are within a limited geographical area. Connection between the computers may be through cables and/or microwave transmission. |
| microwave transmission | Electronic communication without the need for cables. |
| modem (abbreviation of modulator/demodulator) | 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 a network, independently of the overall message. |
| networking | Making use of a network |
| parity bit | Error-detecting procedure that appends a binary digit to a group of binary digits. The sum of all the digits, including the appended binary digit, establishes the accuracy of the data after input, transmission, storage or processing. |
| protocol | International rules that ensure the transfer of data between systems. A protocol is recognized as the standard for a specific type of transfer is called standard protocol. For example: TCP/IP is a standard protocol. |
| TCP/IP | Communications protocols used to connect hosts on the Internet |
| Wide Area Network | Computer network where all the connected computers are in a larger geographic area than that served by a LAN or a MAN (Metropolitan area network) |
