Network And Topology

  1. 1. Types Of Network & types of topology<br />Prepared By : Pruthvi & Pawan<br />
  2. 2. What do you mean by Network?<br />Networking is the concept of sharing resources and services. a network of computers is a group of interconnected system sharing resources and interacting using a shared resources and interacting using a shared communication link.<br />The shared resource can be data a printer a fax modem or a service such as a database or an email system<br />
  3. 3. Types Of Network <br />LAN - Local Area Network <br />WAN - Wide Area Network <br />MAN - Metropolitan Area Network <br />SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network <br />CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network <br />PAN - Personal Area Network <br />DAN - Desk Area Network <br />VPN<br />Pear To Pear<br />
  4. 4. LAN<br />A LAN connects network devices over a relatively short distance. <br />A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs (perhaps one per room), and occasionally a LAN will span a group of nearby buildings.<br />LANs are also typically owned, controlled, and managed by a single person or organization. <br />
  5. 5. MAN<br />A network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. A MAN is typically owned an operated by a single entity such as a government body or large corporation. <br />
  6. 6. WAN <br />A WAN spans a large physical distance. The Internet is the largest WAN, spanning the Earth. A WAN is a geographically-dispersed collection of LANs.<br /> A network device called a Router connects LANs to a WAN. In IP networking, the router maintains both a LAN address and a WAN address. <br />
  7. 7. VPN<br />A secure network that uses the Internet as its backbone but relies on firewalls, encryption and other security<br />A pipe traveling through the Internet<br />
  8. 8.
  9. 9. Peer to Peer Network<br />Networks that connect from one PC to another PC.<br />Common use is the downloading and trading of files.<br />Advantages:<br />Easy installation<br />Low maintenance cost<br />

  11. 11. Other Networks<br />Campus Area Network - a network spanning multiple LANs but smaller than a MAN, such as on a university or local business campus. <br />Storage Area Network - connects servers to data storage devices through a technology like Fiber Channel.<br />System Area Network - links high-performance computers with high-speed connections in a cluster configuration. Also known as Cluster Area Network. <br />
  12. 12. Continue…<br />Personal Area Network: Connection of computer to peripherals or other computers. It is used to Connect PDA and desktop computer.<br />
  13. 13. Topologies<br />A topology describes the configuration of a communication network. <br />A topology describes the physical and the logical interconnection between the different nodes of a network. <br />Network topologies are classified as <br />Physical<br />Logical <br />Signal <br />
  14. 14. Continue…<br />A Physical topology describes the mapping of the network nodes and the physical connections between them.<br />A Signal topology describes the paths, which the signals take while they pass over the network. <br />The mapping of the paths taken by data as they travel over the network is known as a logical topology.<br />
  15. 15. Types Of Network Topologies<br />Bus Topology<br />Ring Topology<br />Mesh Topology<br />Star Topology<br />Tree Topology<br />
  16. 16. Bus Topology<br />All the nodes of a network are connected to a common transmission medium having two endpoints. All the data that travels over the network is transmitted through a common transmission medium known as the bus or the backbone of the network.<br />Bus topology is easy to handle and implement and is best suited for small networks. <br />The downside of this topology is that the limited cable length limits the number of stations, thus limiting the performance to a less number of nodes.<br />
  17. 17. Bus Topology<br />
  18. 18. Ring Topology<br />In a ring topology, every node in the network is connected to two other nodes <br />The data that are transmitted over the network pass through each of the nodes in the ring until they reach the destination node. In a ring network, the data and the signals that pass over the network travel in a single direction. <br />The ring topology does not require a central server to manage connectivity between the nodes and facilitates an orderly network operation. But, the failure of a single station in the network can render the entire network inoperable. <br />
  19. 19. Ring Topology<br />
  20. 20. Star Topology<br />In this type of network topology, each node of the network is connected to a central node, which is known as a hub. <br />The data that is transmitted between the network nodes passes across the central hub. <br />The centralized nature of a star network provides a certain amount of simplicity while also achieving separation of each device in the network. <br />The disadvantage of a star topology is that the network transmission is largely dependent on the central hub. The failure of the central hub results in total network inoperability.<br />
  21. 21. Star Topology<br />
  22. 22. Mesh Topology<br /> A Full Mesh network , each network node is connected to every other node in the network. Due to this arrangement of nodes, it becomes possible for a simultaneous transmission of signals from one node to several other nodes. <br />A Partially connected mesh network, only some of the network nodes are connected to more than one node. This is beneficial over a fully connected mesh in terms of redundancy caused by the point-to-point links between all the nodes. <br />The nodes of a mesh network require possessing some kind of routing logic so that the signals and the data traveling over the network take the shortest path during each of the transmissions.<br />
  23. 23. Tree Topology<br />It is also known as a hierarchical topology and has a central root node that is connected to one or more nodes of a lower hierarchy. <br />In a symmetrical hierarchy, each node in the network has a specific fixed number of nodes connected to those at a lower level.<br />
  24. 24. Hybrid Topology<br />Hybrid network topologies, which are composed of a combination of two or more basic topologies.<br />
