  Introduction Network topologies describethe ways in which the elements of a network are mapped. They describe the physical and logical arrangement of the network nodes.

  TopologyType StarTopology RingTopology BusTopology TreeTopology MeshTopology

  StarTopology Star Topology isa network topology in which each network component is physically connected to a central node such as router, hub, or switch. In a star topology, the central hub acts like a server and the connecting nodes act like clients.
• 7.
  StarTopologyAdvantages & Disadvantages Advantages Its speed is very high.  Easy to install and reconfiguration. The network is highly scalable. Less expensive. Disadvantages It is very expensive. Maintenance cost is very high. Failure of central hub will effect the entire network. Performance is based on the single concentrator i. e.hub. Maintenance cost is very high.
• 8.
  RingTopology Ring topology isa type of network configuration where devices are connected in a circular manner, forming a closed loop. In this setup, each device is connected to exactly two other devices, creating a continuous pathway for data transmission.
• 9.
  RingTopologyAdvantages & Disadvantages Advantages Thedata transmission is high speed. Easy to install and expand. The possibility of collision is minimum. Dependability. Disadvantages Less secure. The failure of a single node in the network can cause the entire network to fail. Troubleshooting is difficult in this topology.
• 10.
  BusTopology Bus topology isa specific kind of network topology in which all of the various devices in the network are connected to a single cable or line. In general, the term refers to how various devices are set up in a network.
• 11.
  BusTopologyAdvantages & Disadvantages Advantages Verycost effective as compared to other network topology i.e. mesh and star. Easy to expand by joining the two cables together. Coaxial or twisted pair cables are mainly used. It is easy to connect or remove devices in this network without affecting any other device. Disadvantages If the main cable is damaged, the whole network fails . This network topology is very slow as compared to other topology. Troubleshooting individual device issues is very hard. Additional devices slow the network down.
• 12.
  TreeTopology In a computernetworking, tree topology is a type of network topology that resembles a tree. In a tree topology, there is one central node and each node is connected to the central node through a single path. Nodes can be thought of as branches coming off the trunk.
• 13.
  TreeTopology Advantages &Disadvantages Advantages It can support a large number of nodes. It can be easily expanded. Error detection and error correction are very easy in a tree topology. Disadvantages It can be difficult to troubleshoot issues in a tree topology as each node is connected to multiple other nodes. The cost is high because of cabling. If the central hub gets fails the entire system fails.
• 14.
  Mesh Topology A meshtopology is a network setup where each computer and network device is interconnected with one another. This topology setup allows most transmission to be distributed even if one of the connections goes down. It is a topology commonly used for wireless networks.
• 15.
  MeshTopologyAdvantages & Disadvantages Advantages Capableof handling heavy traffic. A single devices failure has no impact on the network. Provides privacy and security. Data transmission is reliable. Disadvantages High price. Significant duplicate connection risk. Installation and reconnection is difficult.
