Communication has always been an integral part of human life. Telecommunication refers to distant communication. In this chapter, we will have a quick revision about the concepts of communication, modes of communication we use in everyday life, and introduction to telecommunication.

What is Communication?

Communication is the sharing of meaningful information between two parties (or people).

If someone talks to you in a language you don't understand, we do not refer to that as communication. Because you are not able to understand what the speaker is trying to say. So, there should always be the exchange of views, ideas, thoughts, and other meaningful or precise information only

What are the Modes of Communication?

Depending on how the information is exchanged, there are few modes of communication. They are:

  1. Verbal communication: Communication that is done via the exchange of views or thought, orally is known as verbal communication. Example: face-to-face talk, telephone call, etc.
  2. Non-verbal communication: Communication done without using 
  3. Visual communication: Communication done with the help of written ideas, or graphics is known as visual communication. Example: textbooks, traffic signs, etc.

Introduction to Telecommunication

The word telecommunication is formed by combining two words 'tele' and 'communication'. 'Tele' refers to far and 'communication' refers to exchange of useful and meaningful information.

Thus, telecommunication refers to the use of computer technologies, software, and hardware, to make distant communication between two or more nodes possible.

For example: Internet, Telephone networks, etc.

Components of Telecommunication

In order to setup a telecommunication network, there are few pre-requisites to be established. Such infrastructures and software requirements have been mentioned below:

  • Terminals: These are the start and end point for the whole process and can also be referred to as sender and receiver.
  • Telecommunication Channels: These are the physical or electronic pathway (medium) through which data is likely to be transmitted.
  • Telecommunication Processors: These process the data from the point of transmission to the point of receipt.
  • Control Software: These software control the way how data is being transmitted in the network and may act as traffic police.
  • Messages: These are the actual information to be shared between nodes.
  • Protocols: These are the guiding principles or sets of rules that enable communication between various computer devices over a network and also govern transmission process.
