• The bus topology connects all nodes on a peer-to-peer LAN with a single cable.
– this single cable, called a bus, is shared by all nodes, which mean only one transmission is allowed at a time.
– To send a transmission, a node first must announce to the entire network that it will be sending a transmission.
– The transmission, which includes the destination node address, is ignored by all nodes except the destination node, which accepts it.
– A peer-to-peer LAN with a bus topology is easy and inexpensive to install and nodes can be added or removed without difficulty.
– If a problem occurs with the bus, the entire network becomes inoperable until that problem is solved. Adding the addition nodes also can slow down the transmission process
