Telephone communication, or telecommunication, refers to the practice of communication over a telephone. Although other forms of communication are also possible over the same transmission lines, voice communication is the most common.Know More
Telephone communication was first made possible in 1876 by Alexander Graham Bell, and it was subsequently improved upon by many others. The typical components that make voice telecommunication possible are a microphone for capturing the person's voice, a speaker to reproduce the other person's voice, a dial pad to initiate a call, and a ringer to announce an incoming call.
Telephones and telephone calls were initially too expensive for the majority of households. As a result, only businesses and the very wealthy had access to them. Telephone communication revolutionized the way businesses performed work. It was no longer necessary for long-distance communication to occur over days or weeks because a phone call could be made in an instant.
Since 1876, many advances have built upon the capability that was initially introduced with the first telephone. Telephone lines have also changed greatly to handle the consistently increasing variety and amount of communication traversing them. Telephones, which were originally only capable of voice communication, perform such a variety of functions that entire guidebooks have been written on how to make full use of them.
