An Overview of Computer Network Topology 

Computer Network Designs,

Here you will learn network topology introduction, how compute connected, bus, star, hub, hybrid, mesh, tree topologies and netw design. In Computer Networking “topology” refers to the layout the connected devices. Network Topologies can be physical or lo section I will illustrate on the different types of the topologies.

Physical Topology means the physical design of a network including the devices, location installation.

Computer Glossary

Logical Topology refers to the fact that how data actually transfers in a network as oppose

Ethernet

Topology can be considered conside red as a virtual shape or structure of a network. This shape actuall correspond to the actual physical design of the devices on the computer network. The com home network can be arranged in a circle shape but it does not necessarily mean that it pre topology.

Computer network topologies can be categorized in the following categories. • bus • star • ring  ring  • mesh • Tree. Tree. Hybrid networks are the complex networks, which can be built of two or more above ment topologies. Bus Topology

Routing Explained

Bus topology uses a common backbone to connect all the network devices in a network in shape. A single cable functions as the shared communication medium for all the devices at this cable with an interface connector. The device, which wants to communicate send the b message to all the devices attached with the shared cable but only the intended recipient ac and process that message.

Also, Bus network wor  limited devices. Performance issues are likely to occur in the Bus topology if more than 12 computers are added in a Bus Network. Additionally, if the Backbone cable c able fails then all n  becomes useless and no communication fails among all the computers. Unlike in the Star t which if one computer is detached from a network then there is not effect on the other com network. Ring Topology 

In ring Network, every computer or devices has two adjacent neighbors for communicatio network, all the communication messages travel in the same directory whether clockwise o clockwise. Any damage of the cable of any cable or device can result in the breakdown of network. Ring topology now has become almost obsolete. FDDI, SONET or Token Ring Technology can be used to implement Ring Technology. Ri can be found in office, school or small buildings.

 

Star Topology 

In the computer networking world the most commonly used topology in LAN is the star to topologies can be implemented in home, offices or even in a building. buildin g. All the computers in topologies are connected to central devices devic es like hub, switch or router. The functionality of devices is different. I have covered the detail of each networking devices in the separate po website. Computers in a network are usually usuall y connected with the hub, switch or o r router with Unshielded Twisted Pair (UTP) or Shielded Twisted Pair Cables.

As compared to the bus topology, topolog y, a star network requires more devices & cables c ables to comple The failure of each e ach node or cable in a star network, won’t take down the entire network   as compared to the Bus topology. However if the central connecting devices such su ch as hub, switch or router fails due to any re ultimately all the network can come down or collapse. Tree Topology 

Tree topologies are comprised of the multiple star topologies on a bus. Tree topologies inte multiple star topologies together onto a bus. Only the hub devices can connect directly wit

 

and each Hub functions as a root of a tree of the network devices. This bus/star/hybrid co supports future expandability of the computer networks, much better than a bus or star. Mesh Topology 

Mesh topology work on the concept co ncept of routes. In Mesh topology, message sent to the desti

take any possible shortest, easiest to route to reach itster, d estination. destination. messages are usually broadcasted every compu computer, especially In in the busprevious topology.topologies Similarly topology message can travel in only o nly one direction i.e clockwise or anticlockwise. Internet Mesh topology and the message finds its route for its destination. Router works in find the messages and in reaching them to their destinations.The topology in which every devices c every other device is called a full Mesh topology unlike in the partial mesh in which every indirectly connected to the other devices. Summary 

Topologies are the important part of the network design theory. A better network can be b have the knowledge of these topologies and if you know the difference between each topol Similarly you should have the knowledge of each network device so that you can properly according to your network needs. A misconfigured network can result in a waste of time a well as a lots of troubleshooting methods to resolve the issue. So thebasic understanding o topologies and network devices is a must to build a good network.
