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 range of methods and media that dictate how information is transferred from one end to the next. Understanding how this works helps us create reliable and efficient networks that reap the benefits of increased connectivity like improved business efficiencies and productivity as well as technological advancements in automation.

Data communication is the transfer of data between computers through channels or medium. This can be done over cable or satellite signal, radio frequency or wirelessly. A person or device that transmits data is referred to as the sender, while the computer that receives the data is referred to as the receiver. In a data communication network, more than two computers may be involved www.bigdataroom.net/how-to-block-someone-on-hangouts in the process of communication.

Multiplexing and demultiplexing are useful technology for communication that allows multiple signals to be sent across the same medium at the same time, maximizing bandwidth usage and decreasing costs. Both processes require special hardware capable of combining and separate these signals. This function is typically performed by custom integrated circuits which are present in a wide range of communication products including phones, computers, and printers.

Full-duplex communication is the mode of data communications that allows simultaneous two-way communication within a pair of devices. This is a more complex mode than simplex transmission since it requires the capability to send and receive data at the same time.
