  • 1. Project on Network Topology Vipul S. Kale Computer Programming
  • 2. Topology’s
  • 3. History of Topology
    • 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 .
  • 4. Introduction
    • 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.
  • 5. Types of Topology’s
    • Star Topology.
    • Bus Topology
    • Ring/Network Topology
    • Tree/Extended Star Topology.
  • 6. Star Topology
    • 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.
  • 7. Features Of Star Topology
    • Advantages-
    • Easy to install and wire.
    • Easy to detect faults and to remove parts.
    • Disadvantages-
    • Requires more cable length than a linear topology. .
    • More expensive.
  • 8. Bus Topology
    • The bus topology is the simplest and most common. It is often used when a network installation is small, simple, or temporary.
  • 9. Features of Bus Topology
    • Advantages-
    • In an active topology network, the computers regenerate signals and are responsible for moving the data through the network.
    • On a bus network, all the computer are connected to a single cable.
    • Disadvantages-
    • Heavy network traffic can slow a bus considerably.
    • A break in the cable or lake of proper termination can bring the network down.
  • 10. Ring Topology
    • 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.
  • 11. Features of Ring Topology
    • Advantages-
    • All the computers have equal access to the network.
    • Even with many users, network performance is even.
    • Allows error checking, and acknowledgement.
    • Disadvantages-
    • Failure of one computer can affect the whole network.
    • It is difficult to troubleshoot the ring network.
    • Adding or removing computers disturbs the network .
  • 12. Extended Star/ Tree Topology
    • Among all the Network Topologies the Tree Topology is a combination of the bus and the Star Topology.
  • 13. Features of Tree Topology
    • Advantages-
    • Point-to-point wiring for individual segments.
    • Supported by several hardware and software venders.
    • Disadvantages-
    • Overall length of each segment is limited by the type of cabling used.
    • If the backbone line breaks, the entire segment goes down.
    • More difficult to configure and wire than other topologies
  • 14. Conclusion
    • 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
