The Basics of Data Communication

Data communication is crucial to our digital world. It connects us with the devices and services we rely on. It includes a variety of techniques and media that determine how information flows from one end to the other. Understanding how this works helps us create efficient and reliable networks that deliver the benefits of greater connectivity like improved business efficiencies and productivity as well as technological advancements in automation.

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

Demultiplexing and multiplexing are two important communication techniques that allow multiple signals to be transmitted across a medium simultaneously, optimizing bandwidth utilization and reducing costs. Both of these processes require specific hardware which can combine and separate signals. This is usually done by custom integrated circuits, which are found in a wide variety of communication products, such as cellphones, computers, and printers.

The data communication mode that allows simultaneous two-way communication between a pair of devices is called full-duplex communication. This is a more complex mode than simplex transmission because it requires the ability to transmit and receive data simultaneously.
