Today we will learn 7 Fundamental Characteristics of Data Communications with Examples applications, advantages, components and types with images.
In today’s generations, technology has reached a different level. The data communications are used in all the latest technology devices such as ships, aeroplanes, satellites, rockets, and the latest navigation system.
The data communications are used for better navigations and enhanced data transmission for better communication.
What is Data Communication With Examples
The word communications can be explained as transferring data and information using transmission mediums like cable, wired or other sources.
In data communications, two or more computers or devices transfer digital or analog data using communications channels.
Communication is used to transfer information from one location to another.
The data transmitted from one device to another is in 1s and 0s, a binary form.
In computer networks, computers, laptops, tablets and mobile phones are connected in a network where data and information are shared via cables and wires.
These networks are called “LAN”, “WAN”.
Some hardware devices are used in computer networks, such as routers, modems, hubs, cables, rj45 connectors, twisted cable pairs, fibre optic cable, etc.
The data and information are also shared using wireless networks such as WIfi and Gifi.
The prime example of data communication is “Internet”.
The technology is ever-changing, and improving the data communication technology consists of both hardware and software.

Fundamental Characteristics of Data Communications System
There are 7 characteristics of a data communications system with examples and images.
In data communication, data and information are shared between two devices. When the data is sent from one end, it should be 100% delivered to the other end to successful data communication.
Therefore the delivery plays an essential role in the field of data communication.
In data communication, data and information sent from one computer are received by another computer is accurate.
Therefore accuracy is considered to be one of the significant characteristics of data communication in the computer system.
The data sent in the network are received in exact time and duration, making them a good source of data communications.
The data not received on time is useless regardless of how important the data is.
The quality is not perfect due to imperfect packets arrivals when sent from one computer in networks.
The speed at which data is sent in the network is one of the significant characteristics of data communication.
Data plays a vital role in business and education; therefore, the information has to be speedily distributed among users.
The data that is received slow delays the process of further processing.
The Internet is the cheaper means of data communication. The Internet can share and transfer data from one place to another at fantastic speed and with low-cost accuracy.
They are very efficient and hence made a remarkable growth in the previous years.
The data communications like email and video calling have made things even easier for communications at a low cost.
What are the 5 Components of Data Communications?
The transmitter is an electronic device that use an antenna to produce signals. Transmitters are used in telecommunications, where radio waves are produced for transmission.
The receivers are used to receive the message or information sent by the transmitter in communication systems.
Text, numbers, signs, symbols, images, sound and videos are considered data or information.
The data, information, and instruction are sent from one location to another using a medium. This medium is called a transmission medium.
The transmission mediums are further divided into.
- Unshielded Twisted Pair Cables.
- Shielded Twisted Pair Cables.
- Optic Fiber Cables.
The communications are established with the help of some set of rules and regulations. The rules that are mandatory for data and information sharing are called “Protocol”.
To successfully perform data communications in networks, these protocols are used,
What are the Examples of Data Communications?
5 Examples of Data Communications are
- Internet Connections.
- Video Calling.
Different Types of Data Communication
There are three different types of data communications available.
- Simplex Chanel.
- Half Duplex Channel.
- Full Duplex Channel.
In this channel, data and information can flow in only one direction for data communication.
In this communication, two devices are used; one device is used to send data, and the other is used to receive.
Radio signals can be sent from one end. The receiver cannot send signals from their end.
Half Duplex Channel
In this channel, the data communication is made on both ends but not at the same time.
The telephone line is a prime example of the half-duplex channel.
Full Duplex Channel
This channel provides communication of data on both ends. Both channels are responsible for data and information exchange.
Wireless technology is used to exchange data, information and flow at both ends at once.
