Data communication is the key element that connects us to the devices and services that we depend on in our interconnected digital world. It is comprised of a variety of techniques and media which dictate how information is sent from one end to another. Understanding how it functions allows us to design an efficient and reliable networks that can provide the benefits of increased connectivity including increased efficiency and productivity in business and advancements in automation.
The fundamental concept behind data communication is the transmission of data from one computer to another via a channel or medium. It can be done via cable, satellite signal, radio frequency or wirelessly. A person or device that transmits data is called the sender, while the computer that receives the data is known as the receiver. In a network of data communication, more than two computers can be involved in the process of communication.
Demultiplexing and multiplexing are both useful communication techniques that allow multiple signals to be transmitted over a medium simultaneously, optimizing the bandwidth used and reducing costs. Both require special hardware that is capable of combining and separate these signals. Custom integrated circuits are commonly employed to accomplish this task and are available in a www.bigdataroom.net variety of communications products including cellphones, computers, and printers.
Full-duplex communication is a type of data communication that permits simultaneous two-way communication within two devices. This mode is more complex than simplex transmission since it requires the capability to send and receive data simultaneously.
