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.Euler

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
