Telephone communication

In the previous blogs, the evolution of communication was started to develop from sculpturing to radio signals. Just think for a while that, if we are still continue to use sculpturing techniques. Most people do not understand what that mean to say. But still these techniques are used in the current century not by drawing in the rock. Instead of rock, a new invention of telecommunication is telephones and mobile phones. The previous communication methods are the first steps to make changes in the communication. In early days, our grandfather used to say that, in their days they send messages through trunk call, letters etc. Trunk calls are made only within the country.  Telephone and mobile phones are the new evolution.

Telephones made easy to contact a person from one place to another. What made the invention of telephones? If you compare with previous methods that are used for communication is only through writing. Telephone is the first instrument used to conduct a conversation between two people.

The transfer for innovation doesn’t end. From the normal wired telephone equipment changed to wireless equipment. The pictures will demonstrate the changes that are made in telephones. When the telephone was introduced, many people used to share their number to their friends and families will be the first preference when they met.

If you see the improvements in telephone, firstly it has started in the metropolitan cities by laying wires underground around the cities. Then later through junction boxes to connect other cities. Likewise it passed over to country to country. Moreover, through telephone inventors added few more facilities like fax, caller id, led, and different kinds of ringing sounds.

Next blog will discuss about, what did the telephone invention lead to?
