What is data communication and its types?

Hint: Data Communication is made up of two words: data and communication. Text, image, audio, video, and multimedia files. The act of sending or receiving information is known as communication.

Complete step by step solution:
Digital communication is the exchange of data between a source and a receiver across a transmission medium such as a wire cable. Data communication is the process of sending and receiving data from one device to another. There are three types of data communication:

1. Simplex Communication: It is one-way communication, or unidirectional communication, in which one device only receives data and another device only transmits data, and both devices use their whole transmission capacity. For instance, in the Internet of Things, data entry with a keyboard

2. Half-duplex communication: It is two-way or bidirectional communication in which both devices can send and receive data but not at the same time. When one device sends data, the other just receives data and vice versa. For instance, a walkie-talkie.

3. Full-duplex communication: It is two-way or bidirectional communication in which both devices can send and receive data at the same time. For instance, Mobile phones

Note: The transport of data between two sites is the focus of data communication networks. Data starts from the source and ends up at the sink, which is also known as the destination. It can also be categorized based on the medium through which the signal travels.
