Data communication is the primary component that connects us to the devices and services that we depend on in our connected digital world. It includes a variety of methods and technologies that determine the way information is transmitted from one end to the other. Understanding how this works can help us create reliable and efficient networks that can reap the benefits of greater connectivity, such as improved business efficiency in productivity, as well as advancements in automation.
The principle of data communication is the transmission of data from one computer to another using channels or mediums. It can be done using a wire cable or radio frequency, satellite signal or wirelessly. The person or device that transmits data is known as the sender, while the computer that receives the data is referred to as the receiver. A data communication network may include more than two computers involved in a communication.
Multiplexing and demultiplexing are useful technology for communication that allows multiple signals to be sent over the same medium at the same time, maximizing bandwidth usage and decreasing costs. Both of these processes require special hardware that is able to combine and then separate these signals. Custom integrated circuits are commonly used to perform this function and www.bigdataroom.net are available in a variety of communications products that include cell phones, computers, and printers.
Full-duplex communication is the mode of data communication that allows simultaneous two-way communication within a pair of devices. This mode is more complicated than simplex transmission, since it requires the capability to send and receive data simultaneously.
