The Basics of Data Communication

Data communication is the essential element that connects us to the devices and services that we depend on in our interconnected digital world. It covers a range of techniques and media that dictate how information is transmitted from one end to another. Understanding how it functions allows us to create a reliable and reliable networks that offer the benefits of increased connectivity like increased efficiency and productivity in business and new innovations in automation.

The fundamental concept behind data communication is the transfer of data from one computer to another via the medium or channel. It can be done via a wire cable, radio frequency, satellite signal, or wirelessly. The sender is the person or device transmitting data and the receiver is the computer receiving the data. In a data communication network, more than two computers may be involved in the process of communication.

Multiplexing and Demultiplexing is a set of communication techniques that optimize bandwidth use and cut costs. Both processes require special equipment which can combine and separate signals. This data communication task is typically carried out by custom integrated circuits which are found in a variety of communication devices, such as 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, since it requires the ability to transmit and receive data at the same time.
