This can have dangerous consequences because any break in the cabling brings the network to its knee.

Bus Network Topology requires a multipoint connection.Īll nodes on the bus topology have equal access to the trunk. If the message is missed or not recognized, it reaches the end of the cabling and dissipates at the terminator. Since the bus network is nothing more than a set of cables, connectors, and terminators, the signal is not amplified when traveling through the wiring.ĭata communication message travels along the bus in both directions until it is picked up by a workstation or server NIC. A terminator specific to the type of cable used placed on each end node of the network (if a cable used 50 Ohm, 50 Ohm terminators must use). In general, passive networks based on contention (so-called because each computer has to compete for the transmission time).īus networks usually use coaxial cables that connect to each of the computers through T-shaped connectors. Bus-connected computers act “expectantly,” that is, before transmitting data, they verify that none of the other computers on the bus are transmitting information, sending packets when the connection is free. Without a terminator the electrical signal would reach the end of copper wire and bounce back, causing errors on the network.īus networks make up what is known as a passive topology. It consists of one continuous length of cable (trunk) that is shared by all the nodes in the network and a terminating resistor (terminator) at each end that absorbs the signal when it reaches the end of line. The physical Bus Network Topology is the simplest and most widely used of the network designs.
They are, Bus Topology, Ring and Star Topology.
The three simple Topology that are combined to form a basic Network Topology. Primary-Secondary: In this, one device controls the traffic and all other devices transmit through primary device. Peer to Peer: In this relationship, all the devices in the network have equal status in sharing the link. The nodes in a network can have following two relationships:ġ.
