Data communication is crucial to our modern world. It connects us with the devices and services we depend on. It is comprised of a variety of methods and technologies that determine the way information is transmitted from one end to another. Understanding how this works helps us to design reliable and efficient networks that provide the benefits of greater connectivity, such as improved business efficiency in productivity, as well as advancements in automation.
Data communication is the transfer of data between computers via channels or medium. This can be accomplished via the use of a wire cable, radio frequency, satellite signal or wirelessly. The sender is the person or device transmitting data and the receiver is the device that receives the data. A data communication network could include more than two computers involved in a process of communication.
Multiplexing and Demultiplexing are communication techniques that optimize bandwidth use and cut costs. Both of these processes require specialized equipment that can combine and then separate signals. This function is often performed by custom integrated circuits which are used in a variety of communication products including computers, cell phone, and printers.
Full-duplex communications is the type of data transmission that permits simultaneous two-way communication within Homepage two devices. This mode is more complicated than simplex communication because it requires the ability of sending and receiving data simultaneously.
