Network Transmission

The term Transmission hints at movement. It can be said that Transmission means moving a bunch of information units  in a certain time.


Transmission may be fast, or it may be slow. Fast Transmission is a guarantee of Network user satisfaction. Slow Transmission means problems. It is the objective of Network design to ensure fast transmission. Fast Transmission comes at a premium. Slow transmission has a penalty. It is undesirable. 

Transmission is of information. An information source can be a transmitter.Such information source is the origin of transmission. 

Networks help in information transmission. It helps to carry information from the transmitter to a receiver. The receiver is at the end-point. 

If Transmission is slow, it is painful. Slow Transmission creates problems. In case of slow transmission, the receiver will have to wait for long for the next information.

Suppose a receiver has fast receiving speed. If a transmitter has many things to transmit, the slow transmitter will increase the pain of a fast receiver. Because, a fast transmitter cannot be handled by a slow receiver. Yes, information will overflow from receiver.

This problem of slow transmission has a wise solution. When information is transmitted, transmission is allowed to continue. The receiver is not immediately activated. The transmitted information is allowed to be deposited in an intermediate empty object. This is a buffer. The information holding capacity of the intermediate empty object ( empty buffer ) is equal to the information pulling capacity of the receiver. 

Mind, the transmission speed is slow. So, the intermediate object will fill up slowly. After a certain time, slowly filling up, the intermediate object ( buffer ) will be full. When the intermediate object ( buffer ) is full, the receiver is alerted. The completely full intermediate object ( buffer ) transfers information to the receiver. 

We observe that the receiver is not activated for every information piece that is transmitted. The receiver comes into the picture only for less times. Only when the intermediate object ( buffer ) between transmitter and receiver is full. So, we have seen how a fast receiver adjusts with a slow transmitter. The intermediate object ( buffer ) works here.

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 ...
