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.

Local-Area Networks

Local-Area Networks ( LANs ) are restricted to a small area. Such Networks may be established within a building. Computers that are part of Local-Area Networks are Personal Computers ( PCs ) or microcomputers. These Computers are connected to each other. Simple communication lines connect these Pers Networks bring people together. When people join  hands teamwork becomes possible. The structural composition of LANs simplifies teamwork. In other words, LAN hardware supports teams having similar processing requirements. LAN Computers readily support personalization of tasks allocated to professionals.  Office staff can work together and share information. This improves the efficiency of the entire workforce. It has been noted that here all the Networked Computers are Personal Computers. They are of equal capacity. Mostly LAN users have similar tasks. If situations allow, a user is independent to access any Computer to serve his purpose. LAN users can exercise the option of secu...

Computers - An Introduction

Computers are man made machines. They are made to work very fast. Working fast they can solve  big and small problems.  Modern science has given us these computers. They are very popular. Computers affect and change lives. They keep us happy.The happiness grows. Computers are quick and smart. Great problem solvers and simplifiers are our computers. They can do our work without stopping. Focus is on doing only what is needed. Not needed, not done.  Computers are  life-less servants. They cannot think or make decisions on their own. They are empowered to work. They are given each and every thing so that they carry out our orders. Orders are respected by computers. The manner in which computers work is wholly dependent on man.  The quality of service provided by computers is remarkable. They are loved by human beings. Computers are known for smart and quick service. Computers do not give wrong results. Correct answers are always given. Questions which are difficult...

Euclid's Algorithm

The Greatest Common Divisor ( GCD ) of  two numbers is a number. The number ( GCD ) causes division of the two numbers. This number ( GCD ) is the greatest number that is possible. This divisor partially forms the two numbers. Adding  the divisor successively may result in formation of the two numbers. One can note that when the divisor is the greatest, the division of the dividend is the sharpest. The division operation is very effective. When the Greatest Common Divisor of two numbers is considered, we think of a number that can cause division of both the numbers. Here the two numbers are unequal. The Greatest Common Divisor causes divisions of the two numbers differently. This is clear from the two different quotient values.  The GCD value is very interesting to note. It relates very well with the two numbers. The GCD of two even numbers is also an even number. The GCD of two odd numbers is an odd number. So, we can say that GCD is an abstraction of the two numbers in ...
