5 Components of Data Communications Network and Its Functionality

Introduction To Data Communications
Dear readers, this article will learn 5 components of data communications in computer networks with its functionality and examples, types, and characteristics in an easy language.

The term data communication in simple words can be explained.

Transferring or sharing data and information between two computers or devices in a network.

These devices or computers must be capable of sending and receiving information between them called “Data Communication.”

In this era, technology is developing rapidly, beyond our imagination. We come across numerous new inventions and discoveries in various fields in our daily routine lives.

The data communication industry also developed dramatically over a few decades.

Data communication is used in airplanes, ships, and satellites; various technologies use navigation systems for communication.

The data transfer and exchange has been made very efficiently with the modern means of data communications.

What is Data Communication in Networks With Examples?

Data communication can be termed the exchange of data and information from one point to another or from one location to another.

In this process, one computer or device sends data called as sender to another computer called the receiver.

This data communication can occur between two devices or computers or between multiple computers in a computer network.

What is Data Communication in Networks

They are responsible for transferring or exchanging data in the form of digital or analog between computers that are connected with the help of a communication channel.

The data and information are transferred in signals from one location to another.

Data communication in computer networks helped in growing business globally.

The data and important information can be quickly transmitted from one location to another, eventually helping make rapid decisions.

This quick decision-making ability helped many businesses grow more efficiently than ever before, as we all know that we live in a global village.

The majority of the business has a global reach; therefore, quick decisions positively impact clients.

IT companies, online education forums, social media websites, video chatting, and conferencing are making the lives of humans more up to date as the information can be accessed within just a few clicks.

The internet is considered the most used means of data communication as they are a fast and reliable source of data and information.

Using the internet data communication process can be made very easy with the internet.

The data and information can be shared via Google drives, email, or directly uploading text, documents, spreadsheets, images, and videos.

The internet connection can be established in the wireless method or wired method.

What are the 5 Components of Data Communications and its Functionality?

There are 5 components of data communication in a network are as follows.
  • Transmitter/Sender
  • Receiver
  • Message / Data
  • Medium
  • Protocol
Transmitter or Sender

The sender can be termed a device that sends data from one location to another.

The sender is a computational device capable of transmitting data and information from one end to the destination.

This sender can be a computer, laptop, walkie-talkie, smartphone, smart watches, or just by video chatting and video conferencing.


A receiver can be a computer designed and developed to accept data and information sent by the source. The receiver can be termed as the destination where data has to reach.

The receiver can be a computer, television, laptop, fax, smartphone, etc.

Message / Data

The data and information is exchanged between sender and receiver with the help of communication channels.

The data can be text, document, spreadsheets, symbols, images, pictures, videos, numbers, sound, etc.

Transmission Medium

The data is transferred from one location to another location; the source from where the data is sent is called “sender”; on the other hand, the receiver (destination) who receives the data is called “receivers.”

The data needs a medium to transfer data from sender to destination successfully, called “Transmission Medium.”

The transmission medium can be further categorized as
  • Unshielded Twisted Pair Cables.
  • Shielded Twisted Pair Cables.
  • Optic Fiber Cables.
  • Wireless Medium

The data communication between sender and receiver to transfer data from one point to another is done using certain rules and regulations they are called “Protocol.”

To perform successful data communication, these protocols must be followed.

Different Types of Data Communications Network?

The data communication networks can be of different types; they are 
  • Local Area Network (LAN)
  • Metropolitan Area Network (MAN)
  • Wide Area Network (WAN)
  • Personal Area Network (PAN).
  • Wireless Networks

  1. Hi colleagues, good piece of writing and pleasant arguments commented at this place, I am actually enjoying by these.

  2. I’ve been browsing online more than 3 hours today, yet I never
    found any interesting article like yours. It’s pretty worth enough for me.
    In my view, if all webmasters and bloggers made good content as
    you did, the web will be a lot more useful than ever before.

  3. I know this website gives quality depending articles
    or reviews and additional stuff, is there any other website which offers such things in quality?
