Telephone is one of the most remarkable inventions of modern science. It was invented in 1875. It was invented by an English scientist, named Alexander Graham Bell.
With the help of telephone a person can talk to another person. Telephone has added to the comfort of the modern man. It is, in fact, a thing more of necessity than luxury these days. In our hour of need, telephone helps us like a true friend: It can be used to talk to any person in the world provided there are telephones available at both ends.
A telephone is connected by an electric wire. Each telephone is allotted a number. When a person wants to speak to another, he dials the number, and the exchange connects the two telephones.
The emergence of mobile phone has made it really very popular, as we can find it with all persons walking in the street from the richest to the poorest. It has, in fact, revolutionised the way people communicate. One can contact anyone from any where, thanks to mobile phone.
There are some-demerits of telephone as well. One thing that telephone has almost destroyed for sure is the art of letter writing among most men. Sometimes people use a mobile telephone while walking on the street or driving/riding a vehicle, and it enhances the possibility of an accident. So, when a person needs to talk to another on a mobile telephone, he should stop his vehicle on a side and talk as long as he feels like, without causing any possibility of an accident.
