The Basics of Data Communication

Data communication is an essential component that connects us the devices and services that we depend on in the interconnected digital world. It includes a variety of techniques and media which dictate how information is transferred from one end to the other. Understanding how this works can help us design efficient and reliable networks that can reap the benefits of greater connectivity, such as improved business efficiency, higher productivity, and advancements in automation.

Data communication is the transfer of data between computers through the medium or channel. This could be accomplished via wire cables, satellite signal, radio frequency or wirelessly. A device or person who transmits data is called the sender and the computer which receives the data is known as the receiver. A data communications network may include more than two computers involved in a communication.

Multiplexing and demultiplexing are both communication technologies that optimize bandwidth usage and cut costs. Both of these methods require specialized see it here hardware that can combine and then separate signals. This task is typically carried out by custom integrated circuits that are found in a variety of communication devices, such as computers, cell phone, and printers.

The data communication mode that allows for simultaneous two-way communication between a pair of devices is referred to as full-duplex communication. This type of communication is more complicated than simplex transmission, as it requires the ability to send and receive data simultaneously.
