A '''bus network''' is a network topology in which nodes are directly connected to a common half-duplex link called a bus.<ref>{{cite web |url=http://blog.teachbook.com.au/index.php/computer-science/networking-2/network-topologies |title=Network Topologies |archive-url=https://web.archive.org/web/20150720093918/http://blog.teachbook.com.au/index.php/computer-science/networking-2/network-topologies/ |archive-date=2015-07-20 |work=Teachbook Blog}}</ref><ref>{{cite web |last=Janssen |first=Cory |url=http://www.techopedia.com/definition/17045/bus-topology |title=Bus Topology |publisher=Techopedia |access-date=2015-08-04}}</ref>
[[File:Ethernet LAN.svg|thumb|A conceptual diagram of a local area network using bus topology]] A host on a bus network is called a ''station''. In a bus network, every station will receive all network traffic, and the traffic generated by each station has equal transmission priority.<ref>{{cite book | first1=Geoffrey | last1=Knott | first2=Nick | last2=Waites| title = BTEC Nationals for IT Practitioners | publisher = Brancepeth Computer Publications| year = 2002| isbn = 0-9538848-2-1 | quote = ...all stations have equal priority in using the network to transmit.| pages = 395 }}</ref> A bus network forms a single network segment and collision domain. In order for nodes to share the bus, they use a medium access control technology such as carrier-sense multiple access (CSMA) or a bus master.
