Data communication refers to the exchange of data between two or more networked or connected devices. These devices must be capable of sending and receiving data over a communication medium. Examples of such devices include personal computers, mobile phones, laptops, etc.
Data Communication is a process of exchanging data or information In case of computer networks this exchange is done between two devices over a transmission medium. This process involves a communication system which is made up of hardware and software.

This is the course of "Data Communications and Networks. In this lecture we will read Chapter-1(Components of Data Communications System). In this video we will learn below points:
The essential components of data communication are: Message: Information (data) to be communicated (e.g., text, numbers, pictures, video) Sender: The device that sends the data message (e.g., computer, video camera) Receiver: The device that receives the message (e.g., a computer, workstation, television)
