  2. 2. ● Network Topologies ● Types of Networks ● Network Architecture ● Hardware ● Security ● Model ● Activity Overview
  3. 3. Refers to the hardware/software resources of an entire network that enable network connectivity, communication, operations and management of an enterprise network. A metropolitan area network deals with the same components as any campus- level network. Networking Infrastructure
  4. 4. The simplest topology with a permanent link between two endpoints. Switched point-to-point topologies are the basic model of conventional telephony. Point-to-point
  5. 5. In local area networks where bus topology is used, each node is connected to a single cable. Each computer or server is connected to the single bus cable. Bus
  6. 6. A network topology that is set up in a circular fashion in which data travels around the ring in one direction and each device on the ring acts as a repeater to keep the signal strong as it travels. Ring
  7. 7. Hybrid networks use a combination of any two or more topologies, in such a way that the resulting network does not exhibit one of the standard topologies (e.g., bus, star, ring, etc.). Hybrid
  8. 8. A star network is a local area network (LAN) in which all nodes (workstations or other devices) are directly connected to a common central computer. Every workstation is indirectly connected to every other through the central computer. In some star networks, the central computer can also operate as a workstation. Star
  9. 9. Advantages of Star Topology 1) As compared to Bus topology it gives far much better performance, signals don’t necessarily get transmitted to all the workstations. A sent signal reaches the intended destination after passing through no more than 3-4 devices and 2-3 links. Performance of the network is dependent on the capacity of central hub. 2) Easy to connect new nodes or devices. In star topology new nodes can be added easily without affecting rest of the network. Similarly components can also be removed easily. 3) Centralized management. It helps in monitoring the network. 4) Failure of one node or link doesn’t affect the rest of network. At the same time its easy to detect the failure and troubleshoot it. Disadvantages of Star Topology 1) Too much dependency on central device has its own drawbacks. If it fails whole network goes down. 2) The use of hub, a router or a switch as central device increases the overall cost of the network. 3) Performance and as well number of nodes which can be added in such topology is depended on capacity of central device.
