Data communication is the key component that connects us to the devices and services that we depend on in our connected digital world. It encompasses a variety of methods and technologies that govern how information flows from one end to the other. Understanding how this works helps us create reliable and efficient networks that provide the benefits of increased connectivity like improved business efficiencies, higher productivity, and innovations in automation.
The fundamental concept behind data communication is the transfer of data from one computer to another via the medium or channel. This could be accomplished via cable, satellite signal, radio frequency or wirelessly. The sender is the person or device that transmits data, and the receiver is the device that receives the data. In a network of data communication, more than two computers could be involved in the process of communication.
Multiplexing and Demultiplexing is a set of communication technologies that optimize bandwidth usage and cut costs. Both processes require specialized hardware that can combine block number google hangouts and separate signals. This is usually done by custom integrated circuits which are found in a range of communication products such as phones, computers, and printers.
Full-duplex communication is a type of data communications that allows simultaneous two-way communication within two devices. This mode is more complicated than simplex transmission since it requires the ability to send and receive data simultaneously.
