  INTRODUCTION Network topology isthe arrangement of the elements of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, industrial fieldbusses and computer networks. Network topology is the topological structure of a network and may be depicted physically or logicallyIt is an application of graph theory, wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes .Examples of network topologies are found in local area networks (LAN), a common computer network installation. A wide variety of physical topologies have been used in LANs, including ring, bus, mesh , star and ponit to point . 05

  WHAT IS NETWORK TOPOLOGY ? Networktopology is the way a network is arranged , including the physical or logical description of how links and nodes are set up to relate to each other . 06

  A star networktopology is a topology in which each node directly connected to a central hub or server. Star Topology Fig : Star Topology 09
• 10.
  ADVANTAGES AND DISADVANTAGESOF STAR TOPOLOGY • Single Hub. • Allows to manage entire network from single location. • Indipendent nodes allow network to continue if one node is down . • Low setup cost . • Disable whole system if the central hub disturbed • Overall performance is limited . • Performance is based on single conectator i.e hub. 10 0 3
• 11.
  BUS TOPOLOGY Bus topologyis a network topology in which nodes are connected to a single cable that call "bus" . Data flows through this cable . Fig : Bus Topology 11
• 12.
  ADVANTAGES AND DISANVANTAGESOF BUS TOPOLOGY • Allows device connection via single coaxial or RJ45 cable. • Additional cables additional nodes . • Cost effective for smaller networks . • In bus topology its easy to troubleshooting . • Additional nodes slows transmission . • Time consuming and expensive to restore • If the common cable fail whole system is fail . • Sequrity is very low . 12
• 13.
  Ring Topology Ring topologyis a network topology in which nodes are connected and arranged in a circle or ring . Each device connected with exact two other nodes . Fig :Ring Topology 13
• 14.
  ADVANTAGES AND DISADVANTAGEOF Ring Topology • Additional component do not affect the performance of network. • The data transmission is high speedy . • Cheap to install and expand . • Less costly than a star topology . • Failure of single node in network can cause the whole network fail . • Troubleshooting is difficult in this network . • Less sequre . 14
• 15.
  Tree Topology Ring topologyis a network in which a root node and all other nodes are connected like branches of tree . Fig : Tree Topology 15
• 16.
  Advantages And DisadvantageOf Tree topology • It allows more devices to be attached to a single central hub . • Easy to add new device in existing network . • Error detection and error correction is very easy in tree topology . • If the main root or central hub gets fail entire network system is fail . • The cost is high because of cabling . • If new device are added , it become difficult to reconfigure . 16
• 17.
  Mesh Topology Mesh topologyis a network topology where nodes are directly connected to each other with cables. There is no central hub. Fig : Mesh Topology 17
• 18.
  Advantages And Disanvantsgesof Mesh topology • Mesh topology is robust . • Fault identification an isolation is easy • Dedicated link ensure that each connection carry its own data load , eliminating the traffic problem . • Provides privacy and sequrity . • Huge amount of cabling and I/O ports required . • Installation and reconnection is difficult . 18
• 19.
  Point- to -PointTopology Point to point is simple topology that directly links two nodes and reserve the entire bandwith of the connection .Physically point-to-point connections rely on a cable or wire that connects the two end point . Fig : Point-to-point Topology 19
• 20.
  Advantage : • Dedicatedconnection, • Security, scalability, • High-bandwidth communication. Disadvantage • Cost, limited flexibility, • Limited fault tolerance, and • High maintenance and troubleshooting needs. Point-to-point topology 20

  Conclusion Networking topology isan important concept in networking which deals with several topologies, which defines several ways on how several devices can be connected to each other for exchange of data. There are types of topologies based on different factors. 21
