Data Communication
Data communication is the exchange of data between two or more devices. It is a critical part of computer science and information technology, and it is used in a wide variety of applications, from sending emails to streaming video. Data communication can be classified into two main types: analog and digital. Analog data communication uses a continuous signal to represent data, while digital data communication uses a discrete signal to represent data. Digital data communication is more common than analog data communication, and it is used in most modern computer systems.

Types of Data Communication
There are three main types of data communication: simplex, half-duplex, and full-duplex. Simplex data communication allows data to flow in only one direction, from the sender to the receiver. Half-duplex data communication allows data to flow in both directions, but only one device can transmit data at a time. Full-duplex data communication allows data to flow in both directions simultaneously.
Data Communication Protocols
Data communication protocols are sets of rules that govern the exchange of data between devices. There are many different data communication protocols, each of which is designed for a specific purpose. Some of the most common data communication protocols include TCP/IP, Ethernet, and Wi-Fi.
Data Communication Networks
Data communication networks are systems that connect devices together so that they can exchange data. Data communication networks can be classified into two main types: LANs and WANs. LANs are local area networks that connect devices within a limited area, such as a home or office. WANs are wide area networks that connect devices over a large geographical area, such as a country or continent.
Data Communication Applications
Data communication is used in a wide variety of applications, including:
- Sending and receiving emails
- Streaming video
- Online gaming
- Banking
- Shopping
