Data communication is vital to our digital world. It connects us with the devices and services we rely on. It encompasses a variety of methods and media that determine how information is transmitted from one end to the other. Understanding how this works can help us create reliable and efficient networks that can reap the benefits of increased connectivity like improved business efficiencies, higher productivity, and advancements in automation.

Data communication is the transfer of data between computers using a medium or channel. This could be done through the use of a wire cable, satellite signal, radio frequency or wirelessly. The sender is the individual or device that transmits data, and the receiver is the computer receiving the data. In a data communications network, more than two computers may be involved in the process of communication.

Multiplexing and Demultiplexing are communication techniques that optimize bandwidth use and reduce costs. Both of these methods require specialized equipment that can combine and then separate signals. Custom integrated circuits are typically used to perform this function and are available in a variety of communications products including phones, computers and printers.

The data communication mode that allows simultaneous two-way communication between the same pair of devices is referred to as full-duplex communications. This is a more complex mode than simplex transmission since it requires sending and www.bigdataroom.net/how-to-recover-a-corrupt-word-or-zip-file receiving data at the same time.
