Computer topology

  1. 1. Project on Network Topology Vipul S. Kale Computer Programming
  2. 2. Topology’s
  3. 3. History of Topology <ul><li>the first work which deserves to be considered as the beginnings of topology is due to Euler . In 1736 Euler published a paper on the solution of the Königsberg bridge problem which translates into English as The solution of a problem relating to the geometry of position . </li></ul>
  4. 4. Introduction <ul><li>The configuration of a communication network of 'Computer Science' in which the arrangement in nodes of a LAN is connected to each other is known as Topology. It is a term which defines Topology in a simple manner. </li></ul>
  5. 5. Types of Topology’s <ul><li>Star Topology. </li></ul><ul><li>Bus Topology </li></ul><ul><li>Ring/Network Topology </li></ul><ul><li>Tree/Extended Star Topology. </li></ul>
  6. 6. Star Topology <ul><li>This type Topology is often called a multi-port repeater. In a star topology, each device has a dedicated point to point link only to central controller, usually called a hub/server/host. </li></ul>
  7. 7. Features Of Star Topology <ul><li>Advantages- </li></ul><ul><li>Easy to install and wire. </li></ul><ul><li>Easy to detect faults and to remove parts. </li></ul><ul><li>Disadvantages- </li></ul><ul><li>Requires more cable length than a linear topology. . </li></ul><ul><li>More expensive. </li></ul>
  8. 8. Bus Topology <ul><li>The bus topology is the simplest and most common. It is often used when a network installation is small, simple, or temporary. </li></ul>
  9. 9. Features of Bus Topology <ul><li>Advantages- </li></ul><ul><li>In an active topology network, the computers regenerate signals and are responsible for moving the data through the network. </li></ul><ul><li>On a bus network, all the computer are connected to a single cable. </li></ul><ul><li>Disadvantages- </li></ul><ul><li>Heavy network traffic can slow a bus considerably. </li></ul><ul><li>A break in the cable or lake of proper termination can bring the network down. </li></ul>
  10. 10. Ring Topology <ul><li>In a ring topology, each computer is connected directly to the next computer in line, forming a circle of cable. It uses token to pass the information from one computer to another. </li></ul>
  11. 11. Features of Ring Topology <ul><li>Advantages- </li></ul><ul><li>All the computers have equal access to the network. </li></ul><ul><li>Even with many users, network performance is even. </li></ul><ul><li>Allows error checking, and acknowledgement. </li></ul><ul><li>Disadvantages- </li></ul><ul><li>Failure of one computer can affect the whole network. </li></ul><ul><li>It is difficult to troubleshoot the ring network. </li></ul><ul><li>Adding or removing computers disturbs the network . </li></ul>
  12. 12. Extended Star/ Tree Topology <ul><li>Among all the Network Topologies the Tree Topology is a combination of the bus and the Star Topology. </li></ul>
  13. 13. Features of Tree Topology <ul><li>Advantages- </li></ul><ul><li>Point-to-point wiring for individual segments. </li></ul><ul><li>Supported by several hardware and software venders. </li></ul><ul><li>Disadvantages- </li></ul><ul><li>Overall length of each segment is limited by the type of cabling used. </li></ul><ul><li>If the backbone line breaks, the entire segment goes down. </li></ul><ul><li>More difficult to configure and wire than other topologies </li></ul>
  14. 14. Conclusion <ul><li>The Network of Topology differs from place to place. But, however, all of them have their advantages & disadvantages. If the server problem occurs or server gets down, then Topology faces its failure </li></ul>
