INDEX DEFINITION OF TOPOLOGY:- TYPES OF TOPOLOGY:- ADVANTAGES OF TOPOLOGY:- & DISADVANTAGES OF TOPOLOGY:-

What is a Topology?:

What is a Topology? “The way in which the connections are made among all the computers is called the topology of the network”. Network topology specifically refers to the physical layout of the network, specially the location of the computers and how the cable is run between them.

The most common topologies are :- :

The most common topologies are :-

MESH TOPOLOGY:

MESH TOPOLOGY

Advantages :

Advantages Because of the dedicated link, no traffic between computers. Failure of one node computer not affect rest of the network. Because of the dedicated link privacy and security are guaranteed .

Disadvantages :

Disadvantages Complicated implementations Large space is require to run the cables. It is very expensive. Require more cable then other topology.

star topology:

star topology

Advantages:

Advantages Easy to install Easy to detect faults and to remove parts. It is easy to add new computers

Disadvantage:

Disadvantage Require dedicated server Failure of central node can be disturb network. Requires more cable length HUB

BUS topology:

BUS topology

Advantages:

Advantages Low Cost Easy to connect Require less cable. Easy to implement Backbone

Disadvantage:

Disadvantage Entire network shuts down if there is a break in the main cable. It is difficult To troubleshoot a bus. Heavy network traffic can slow a bus considerably

Ring topology:

Ring topology

Advantage :

Advantage Allows error checking, and acknowledgement. Relatively simple as packets travel in one direction. All the computers have equal access to the network.

Disadvantage:

Disadvantage Failure of one computer can affect the whole network. It is difficult to troubleshoot the ring . A single break in the cable can disrupt the entire network.

Hybrid topology:

Hybrid topology Hybrid networks use a combination of any two or more topologies in such a way that the resulting network does not exhibit one of the standard topologies (e.g., bus, star, ring, etc.). A hybrid topology is always produced when two different basic network topologies are connected.

Advantage :

Advantage It provides a better result by it. It can be designed in many ways for various purposes.

Disadvantage:

Disadvantage Difficult to identify the problem if the entire network shuts down. It is costly
