Data communication is an essential component that connects us the devices and services we depend on in our interconnected digital world. It encompasses a variety of methods and media that control how information is transferred from one end to the next. Understanding how it functions allows us to create a reliable and reliable networks that can provide the benefits of increased connectivity like improved business efficiencies and productivity and advancements in automation.

The fundamental concept behind data communication is the transfer of data from one computer to another via a channel or medium. It can be done using the use of a wire cable, satellite signal, radio frequency or wirelessly. A device or person who transmits data is known as the sender and the computer which receives imp source the data is known as the receiver. A data communication network could contain more than two computers involved in a communication process.

Demultiplexing and multiplexing are both useful communication technologies that allow several signals to be transmitted across one medium simultaneously, which results in optimizing bandwidth utilization and reducing costs. Both processes require special equipment that can combine and then separate signals. This function is often performed by custom integrated circuits, which are present in a wide variety of communication devices, such as cell phones, computers and printers.

Full-duplex communications is the type of data communication that allows simultaneous two-way communication between a pair of devices. This is a more complex mode than simplex transmission because it requires sending and receiving data at the same time.
