Star Network Topology

Broadly, Network Topology means the Network Shape. An example of Network Topology is Star Topology.


Star Topology is like a twinkling Star. At the centre, a Hub ( Central ) Computer is placed. Hub Computer is the most important Computer of a Star Network. The Hub Computer is located at the centre of a Star Network. Besides the Hub Computer other Computers are there. Others are spread around the Hub in an arrangement.The arrangement of other non- hub Computers may be in  a circular fashion. The other computers appear at an equal distance from the Hub. The Hub Computer and the other arrangement of Computers makes a Star Topology Network.

Information transfer can take place between Hub Computer and other Computers. But, transfer of information from one Non-hub Computer directly to another Non-hub Computer is not possible. Exchange of information between two Non-hub Computers is only possible by passing information through the Hub Computer.

Local-Area Networks ( LANs ) can be designed to have Star Topology. Star Topology Networks can be implemented in office buildings. Transfer of information is greatly helped. Besides, two Local-Area Networks having the Star Topology can be connected. Adoption of Star Topology leads to good control over transfer of information. 

In the process of information transfer the Hub is always present. We can say that Hub is the most busy computer of Star Topology Network.

Hub Computer plays the most important role here. It is given a fast CPU and large size memory. 

Ready with a fast CPU, the Hub can manage information transfer efficiently. Here information transfer has Hub on the one hand, and sideways placed Non-hub  Computers on the other hand.

The large sized memory of the Hub is helpful. Hub can store all the data demanded by other Computers.

Advantages of Star Network Topology:

  1. Simple design

  2. Easy to rectify faults

  3. Helps to share information

  4. Requires little effort to maintain

Disadvantages of Star Network Topology:

  1. Failure of Hub ( Central ) Computer makes it useless

  2. Communication is centralized

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 ...
