Topology’s

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 .

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.

Types of Topology’s

• Star Topology.

• Bus Topology

• Ring/Network Topology

• Tree/Extended Star Topology.

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.

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.

Bus Topology

• The bus topology is the simplest and most common. It is often used when a network installation is small, simple, or temporary.

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.

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.

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 .

Extended Star/ Tree Topology

• Among all the Network Topologies the Tree Topology is a combination of the bus and the Star Topology.

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

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
