Network Topologies

BUS - All devices are connected to a central cable. Bus networks are relatively inexpensive and easy to install for small networks. Ethernet systems use a bus topology.
RING - All devices are connected to one another in the shape of a closed loop, so that each device is connected directly to two other devices, one on either side of it. Ring topologies are relatively expensive and difficult to install, but they offer high bandwidth and can span large distances.
STAR - All All devices are connected to a central hub. Star networks are relatively easy to install and manage, but bottlenecks can occur because all data must pass through the hub.
MESH - Devices are connected with many redundant interconnections between network nodes. In a true mesh topology every node has a connection to every other node in the network.
TREE TOPOLOGY - A tree topology combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable.
