Data communication is crucial www.bigdataroom.net/how-to-recover-a-corrupt-word-or-zip-file for our digital world. It connects us to the devices and services we rely on. It includes a variety of techniques and media which dictate how information is sent from one end to another. Understanding how this works can help us to design reliable and efficient networks that deliver the benefits of increased connectivity like improved business efficiencies and productivity as well as innovations in automation.

Data communication is the transfer of data between computers via the medium or channel. This could be done through the use of a wire cable, satellite signal, radio frequency or wirelessly. A device or person who transmits data is known as the sender while the computer that receives the data is known as the receiver. In a data communication network, more than two computers may be involved in the communication process.

Multiplexing and Demultiplexing are communication techniques that optimize bandwidth use and reduce costs. Both processes require special hardware that is able to combine and then separate these signals. Custom integrated circuits are frequently employed to accomplish this task and can be found in many communications devices that include cellphones, computers, and printers.

The data communication mode that allows for simultaneous two-way communication between the same pair of devices is called full-duplex communication. This mode is more complicated than simplex transmission because it requires sending and receiving data at the same time.
