Essay on Communication | Meaning and Importance of Communication System
Today communication is playing a great role in our modern life. The invention of telegraphy laid the foundation stone for modern communication system. Telegraphy was followed by telephony and wireless communication systems. With the introduction of satellite communication technology, the speed of information has been increased to a great extent.
The telegraph is one of the oldest forms of Telegraphy .In the age of steam locomotives and ships, this method was considered as a great marvel. In those days messages were sent by using electrical pulses transmitted over long copper wires laid under ground or carried over poles.
The invention of telephone made human communication easier and faster. If two people are living far apart from each other, they can establish contact through the telephone system.
Telephone calls can be made directly between two subscribers without any wire connection. The revolving dial was used in place of crank to send the electrical pulses for this purpose.
The wireless system made possible to communicate over long distances without using wires, electric circuits or other physical media. The radio waves are propagated through space at the speed of light overcoming the problem of distance which was a major drawback of the previous system.
The radio communication system is based on electromagnetic waves generated in radio transmitters and received by wireless receivers.
The first wireless message was sent to America from England in 1897. The wireless communication system has been widely used for two-way telecommunication, broadcasting of radio and television program as well as for distance education etc.
In the modern world the satellite communication systems have become a vital part of our daily life. Satellite communication is a missile which is fitted with a transmitter, receiver and an antenna.
In this system there is only one bounce from one ground segment to another during its whole path from earth station to a satellite in space and vice versa. This is due to the large coverage area of a satellite which acts as a relay station.
Satellite communication system is used for two-way telecommunication, broadcasting of radio and television program etc. The demands of the customers can be fulfilled quickly through this system.
Due to its low cost and high capacity, it has caused a revolution in international long distance telephone communication. This system is being used in cellular network systems for mobile communication purposes.
Computers are another great invention of 20th Century .Their applications have increased manifold during the last four decades especially after the development of microprocessor technology. Now computers are being used to carry out different processes. They are useful to store, process and retrieve information through digital signals. Today computers can be linked to each other by a network connection .We call this a computer network.
