Data communication is the essential element that connects us to the devices and services we depend on in our interconnected digital world. It encompasses a variety of methods and technologies that govern how information flows from one end to the other. Understanding how it works helps us to create a reliable and reliable networks that provide the benefits of increased connectivity including increased efficiency and productivity in business and advancements in automation.
Data communication is the transfer of data between computers via channels or medium. It can be done using a wire cable or satellite signal, radio frequency or wirelessly. The sender is the individual or device sending data, and the receiver is the computer receiving the data. In a network for data communication more than two computers could be involved in the communication process.
Multiplexing and Demultiplexing are two communication techniques that optimize bandwidth use and cut costs. Both processes require special hardware that is able to combine and then separate these signals. This function is often performed by custom integrated circuits which are present in a wide variety of communication products like phones, computers, and printers.
Full-duplex communications is the type of data communications that allows simultaneous two-way communication within a pair of devices. This type of communication is more complex than simplex transmission as it requires the ability of sending and receiving data at the same time.
