Write an essay on the telephone
nignag [31]

<em>I GOT THIS FROM A SITE CALLED http://www.preservearticles.com/201104306064/short-essay-on-telephone.html                                                                                                           </em>Modern man enjoys a number of wonderful gifts of science. The telephone is one of them. It is the quickest means of conveying messages from one place to another. After the invention of this instrument, man has conquered time and space.

The telephone was invented by Graham Bell. The mechanical device of telephone is very simple. In every telephone set there is a transmitter and a receiver. The transmitter sends the voice of the speaker to the listener.

The receiver receives the voice of the speaker. The two telephone sets are connected by wires. If the wires are detached anywhere, the communication is hampered. Nowadays, the use of wires has been replaced by the micro­wave telephone system. Mobile telephone is the latest development of the telephone system.

The telephone is very useful. It helps all kinds of people beginning from merchants to doctors and lawyers. The latest information about the price and stock of the commodity in market can be available through telephone.

Monopoly in business can be checked. Price can be controlled. The police have telephones in their offices and houses. They receive immediate information about any crime or criminal. They keep contacts, with different police stations in order to catch a culprit. The telephone set is very helpful in the Fire Brigade Office. As soon as information about a fire accident reaches this office through telephone, the fire brigade runs to the accident spot and checks fire.

Now-a-days, the telephone has widely spread. This facility has been extended to the villages. There was a time when the telephone set-was regarded as a sign of aristocracy. But today it has become a necessary object in every family. If the members of a family are staying in different places they can sit at their tea-time and talk with. Each other through telephone. It seems then. That the family members are staying together at one peace.

At present, computerised STD facility has improved a lot. Every place in the country and abroad is contacted through a code number. Different places have different code numbers. Computerisation of telephone has simplified the system a lot.
