Network Topology

Network Topology means the arrangement of Computers, which form a Network. The manner of positioning these Computers gives a definite shape to the arrangement. The arrangement of Computers tells about the distribution of these computing units. The Computers are distributed over a certain area. The area could be a Computer Laboratory, office, hospital, or bank.

To determine Network Topology, a survey is conducted. The arrangement of Computers is studied. The layout of the Network communication wires  are also of interest to the surveyor. The observation of the surveyor reveals the shape of the Network. This is Network Topology.

In fact, the Network Topology concept has a graphical background. Here we talk about the graphical shape of a Network ( e.g. Bus-shaped, Star-shaped, etc. ). It is to be noted that this shape broadly results from positioning of Computers. 

So, no wonder, if a Network is laid out for a purpose, it has a shape. This shape is conclusively decided. 

Case Study of Network Topology:

Let us consider a Network Topology example. This is popularly called 'Bus' Topology. A transport service 'Bus' has a straight line structure. So, a  Bus Topology is an arrangement of Computers in the manner of a straight line. Here the Computer Network is fashioned as a straight line.There is a communicating medium. It is a cable that is laid out. This cable is put straight. Computers may be positioned on both sides of the cable. Each  computer is tied to the central middle cable. There are Computers on both the sides of the cable. 

A Computer willing to communicate may place data over the cable. The data placed by a Computer is routed to the central middle cable. Then the communicated data is taken to other Computers. This is how Bus Topology broadly works, and enables Communication of data.
