BASIC TOPOLOGIES USED IN NETWORKING


              Hello friends after successful post on android osworld is now going to post about networking.network means connection of 2 or more devices using switch,hub,or router.switch,hub and rourter are called interconnected devices.today i will talk about 4 basic topologies which are used in networking.folloing are the basic four topologies.

      1:-mesh topology
      2:-star topology
      3:-ring topology
      4:-bus topology

1:-mesh topology










                              in this topology every device is connected to remaining all devices in the network.we can say every devices in the network are directly connected to each other.main advantage of mesh topology is if any connected link is fail then also whole network is in active state.


2:-star topology



                         





        in star topology every devices are connected to hub.they can communicate via hub.in star topology there are multipoint connection between devices and point to point connection between device and hub.easy to reconfigure and isolation.

3:-ring topology



                           in ring topology every devices connected via repeater.there are point to point connection between every devices.in ring topology we can communicate in unidirecation only.if any device is fail we can say whole network is death.repeater is used for regenerate the origenal signal.

 

4:-bus topology


                           in bus topology there is one backbone line and n drop lines every device is connected to backbon using tapes via drop lines.in bus topology there is multipoint connection between all devices.becauseof that multi point connection not easy to isolation in bus topology.

             so friends here i tried to give my best if you like this article then share it to your friends on facebook and twitter...
