The Basics of Data Communication

Data communication is an essential component that connects us the devices and services we depend on in the interconnected digital world. It encompasses a variety methods and technologies that determine the way information is transmitted from one location to another. Understanding how it works helps us to design a highly efficient and reliable networks that provide the benefits of a greater network for enhanced efficiency and productivity for businesses and new innovations in automation.

Data communication is the transfer of data between computers via the medium or channel. This can be done over wire cables, radio frequency, satellite signal, or wirelessly. The person or device that transmits data is the sender and the computer that receives the data is known as the receiver. A data communications network may include more than two computers involved in a process of communication.

Multiplexing and demultiplexing are effective communication technologies that permit multiple signals to be sent across the same medium at the same time, maximizing bandwidth utilization and reducing costs. Both processes require specific equipment which can combine and separate signals. Custom integrated circuits are commonly employed to accomplish this task and are available in a variety of communication devices such as cell phones, computers, and printers.

Full-duplex communications is the type of data communications that allows simultaneous two-way communication between two devices. This type of communication is more complex than simplex transmission since it requires sending and receiving data simultaneously.
