What is TopologyTopology is arrangement of a network, including its nodes and connecting lines.

Bus TopologyBus networks use a common backbone to connect all devices. A single cable, the backbone functions as a shared

communication medium that devices attach or tap into with an interface connector. A device wanting to commu

cate with another device on the network sends a broadcast message onto the wire that all other devices see, butonly the intended recipient actually accepts and processes the message.

Ring Topology

3/3

In a ring network, every device has exactly two neighbors for communication purposes. All messages travelthrough a ring in the same direction (either "clockwise" or "counterclockwise"). A failure in any cable or device

breaks the loop and can take down the entire network.

Star TopologyMany home networks use the star topology. A star network features a central connection point called a "hub" thamay be a hub, switch or router. Devices typically connect to the hub with Unshielded Twisted Pair (UTP) Ether-

net.

Tree TopologyTree topologies integrate multiple star topologies together onto a bus. In its simplest form, only hub devices conect directly to the tree bus, and each hub functions as the "root" of a tree of devices. This bus/star hybrid appro

supports future expandability of the network much better than a bus (limited in the number of devices due to thebroadcast traffic it generates) or a star (limited by the number of hub connection points) alone

Mesh TopologyMesh topologies involve the concept of routes. Unlike each of the previous topologies, messages sent on a mesh

network can take any of several possible paths from source to destination

A mesh network in which every device connects to every other is called a full mesh. As shown in the illustrationbelow, partial mesh networks also exist in which some devices connect only indirectly to others
