- 1Wide Area Network (WAN)A computer network that covers a large geographical area. For example, the web.
- 2Local Area Network (LAN)A computer network that connects to computers within a limited area. For example, an intranet.
- 3Personal Area Network (PAN)A computer network that is used for data transmission among devices. For example, when you print something off from the computer or on your phone.
- 4Virtual Private Network (VPN)A network that is constructed by using public wires, usually the internet, to connect to a private network.
- 5MAC AddressA unique identifier for network interfaces for communications on the physical network segments.
- 6ProtocolAn agreed upon format for transmitting data between devices. A good protocol should define: how to set up and stop a connection, how to start and end a message, how to deal with corrupt data and how to format the data.
- 7PacketBroken up pieces of data. Data is broken up into packets in networking to transfer them. The size of the packets depends on the network designer, but they usually start from 512 bits upwards.
- 8HostnameA label assigned to a device connected to a computer network.
- 9ChecksumA digit representing thee sum of the correct digits in a piece of stored or transmitted data.
- 10Even ParityChecking that the number of 1s in the data word adds up to an even number
- 11Odd ParityChecking that the number of 1s in the data word adds up to an odd number
- 12Bus TopologyA network setup where each computer is connected to a single cable. Usually easy to setup but has a limit on the cable length.
- 13Ring TopologyA network topology in which each node connects to 2 other nodes, creating a single pathway for signals. Although it is a well organised setup, if one station goes down, then the rest will be affected.
- 14Star TopologyA network setup that consists of a central node with multiple nodes connected to it. Though it depends on the central node too much, it is easy to connect new nodes.
- 15Mesh TopologyA topology in which each node relays data for the network. One positive of this is it can be transmitted from different devices. However the overall cost is very high.
