Data Communication System

A communications system is often known as a communications network, a collection of separate telecommunications networks transmission systems, relay stations, tributary stations, and terminal equipment that can typically be interconnected and interoperated to form a unified whole.

There are two types of communication systems based on physical infrastructure: line communication systems and radio communication systems.

Power Line Communication is a communication technique that allows information to be sent over existing power lines. It means that an electronic gadget (for example) may be powered up while also being controlled and data retrieved in a half-duplex manner using only power connections.

Information is sent over space utilizing radio waves in radio communication systems. The information to be communicated is transformed to a time-varying electrical signal called the modulation signal at the sending end by some transducer.

Communication talents are the capabilities to give and receive various types of information communication of fresh ideas, thoughts, or even an update on the project. Examples of Listening, speaking, watching, and empathizing are all communication abilities.

Data communication concept

The transmission of data or information between a source and a receiver is known as data communications. The data is transmitted by the source and received by the receiver. Data Communications do not include the actual production of the information and the information's subsequent action at the receiver.

Simplex communication, half-duplex communication, and full-duplex communication are the three forms of data transmission between various devices. It's a one-way or unidirectional communication between two devices, one acting as the transmitter and the other as the receiver.

Data Communication System Components

The following are the essential components of a data transmission system:

Sender/Transmitter is a term that refers to a person who sends or

The term "sender" refers to a device that sends data or communications. Computer, phone, and fax machine, for example.

  1. Message

The message is the data or information to be sent, such as text, numbers, images, sounds, and videos, among other things.

  1. Communication Channel or Medium

The medium is the path via which data is conveyed from one location to another—for example, a telephone line, fiber optics, and so forth.

  1. Receiver

The term "receiver" refers to a device that receives communications—computer, phone/fax machine, printer, and so forth.

  1. Encoder and Decoder

 In communication systems, encoders and decoders are used to transform signals from one form to another.


Most data can be sent via an internet connection in a particular period.


Bandwidth is sometimes confused with internet speed, although it refers to the quantity of data that can be transferred through a connection in a given length of time (measured in megabits per second).

To describe a data transfer rate of 60 million bits (megabits) per second, bandwidth is generally stated in bits per second, such as 60 Mbps or 60 Mb/s.
