Network Topology

Network Topology

1. A Topology define the arrangement of nodes, cables and connectivity devices that makeup the network (its the layout of the connected devices on a nework)

2. BUS: is a network in which all devices are physically attached to and listen for communication on a single wire.

   • if at some point on the wire there is a break, the entire network is down.
   • it does not need any switches or hubs because the computers simply broadcast all the information down the single wire,
     • All computers connected to that single wire receive the information.

3. Ring: is a network in which the devices are connected in a circle.

   • Data travels around the ring in one direction. When one node sends data to another, the data passes through each intermediate node on the ring until it reaches its destination.
     • If there is a break at some point in the ring, the entire network comes to a halt.

4. Star: is network that has the devices connected to a central hub or switch.

   • the data are sent through hub out to the destination device.
     • this transmission of date may be through another hub or switch to an adjacent network or directly to the device.
   • This network is most commonly used

5. Mesh: is a network that has multiple pathways interconnecting devices and networks.

   • this type of network has redundancy built in with the multiple connections.
     • Internet is based on it and is used most often to connect networks to other networks
