The Basics of Data Communication

Data communication is crucial to our digital age. It connects us to the devices and services we depend on. It encompasses a variety of methods and media that dictate how information is transmitted from one end to another. Understanding how it works allows us to create a reliable and reliable networks that offer the benefits of a greater network like improved business efficiencies and productivity, and innovations within automation.

The fundamental concept behind data communication is the transmission of data from www.bigdataroom.net one computer to another through channels or mediums. This can be done over the wire cable, satellite signal, radio frequency or wirelessly. A person or device that transmits data is known as the sender, while the computer that receives the data is known as the receiver. A data communications network may have more than two computers involved in a communication.

Multiplexing and demultiplexing are both communication techniques that optimize bandwidth use and reduce costs. Both require special hardware able to combine and then separate these signals. Custom integrated circuits are often used to perform this function and can be found in many communications devices including computers, cell phones, and printers.

The data communication mode that allows simultaneous two-way communication between a pair of devices is referred to as full-duplex communication. This mode is more complicated than simplex transmission, since it requires the ability to send and receive data at the same time.
