Network: A Design

A Network is a design work. It is really a product that results from a careful design. We can have a Network of institutions. Or, we can have a Network of Computers. Both Networks ( either of institutions or of Computers ) are very carefully given concrete shape. 


In a Network of Computers, we have Computers as the nodes ( or nodal elements ). Although, there are other elements that make sense, Computers are most dominant, and are the centres of attraction. In other words, the Computers record the most impacting presence in a Computer Network. We can say that Computers are the eye-catching elements of Computer Network architecture.


In a Computer Network, Computers are not the only Network elements. Besides Computers, we have linking elements. Links ( or wire, or any other ) serve to connect nodal points, or Computers, we can say. 


Computers alone cannot make a Computer Network. It is linked Computers that form a Network. The idea of linking is central.


When a Computer Network is under discussion, the thought of Computer Hardware may visit us. It is clearly stated here that it is not necessary that all Computers in a Network have the same hardware. The architecture of Computers can be different. 


One Computer in a Network can have slow speed and it may be of low price. Another Computer in a Network can have high speed. The high speed Computer may cost high. The low-speed-low price, and high-speed-high-price Computers belong to two different hardware categories.


Indeed, Computer Networks are lenient about the type of hardware that is employed in making Computer units.


It is to be noted that a Computer, within a Computer Network, cannot communicate with other Computers that are not part of the given Computer Network.


It can be concluded that a Network enables communication. But we must also say that a Network also establishes a communication boundary. If a Computer wishes  to communicate, it can do so within the Network boundary. The world beyond the Network boundary is unavailable, we can say.

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 ...
