Notes Introduction

We are in the world of advanced Information Technology where things are moving in such a fast
phase. The availability of information becomes cheaper and faster and the facilities existing to
exchange the information among users all across the world has become more simpler due to the
evolving of Information Super Highway. The internet provides fast and inexpensive
communication channels that range from messages posted on bulletin boards to complex
exchanges among many organizations. It also includes information transfer (among computers)
and information processing. E-mail, chat groups, and newsgroups are examples of major
communication media. Let us see the major components of Electronic Communication System
as follows.

6.1 Telecommunication

Telecommunication implies the transmission of information from one point to another through
a communication medium. In today’s dynamic business environment, people, in order to perform
their work activities and to compete successfully, need to communicate electronically within
and outside the organization. As a result, telecommunication takes on a significant role in an
organization. Sometimes, the term data communication, which is a narrow term and refers to
the transmission of data, is also used and thus data communication is a more specific term.
A telecommunication system may be represented by way of a simple conceptual model as
shown in Figure 6.1.

Figure 6.1: A conceptual Model of
Communication System

The data source is the originator of information while data transmission is the receiver of
information. The channel is the path through which the information is transmitted to the
destination from the source. Before an information is sent through the communication channel
it is converted into coded symbols by transmitted encoder, only to be decoded at the receiver’s
end by receivers decoder. The encoded data is transmitted through the channel by an electronic
signal or waveform.

6.2 Communication Technologies in Business

Most traditional business communications rely on telephone and paper-based processes. These
resources do not readily support the level of productive interaction that growing businesses
need to excel, and can be easily overwhelmed in periods of rapid growth.
