Data communication is the essential component that connects us to the devices and services we depend on in our connected digital world. It encompasses various techniques and media that dictate how information flows from one end to the other. Understanding how it works allows us to design a highly efficient and reliable network that delivers the benefits of increased connectivity including improved efficiency and productivity of businesses as well as innovations in automation.
The principle of data communication is the transmission of data from one computer to another using an intermediary or channel. This can be accomplished via the use of a wire cable, satellite signal, radio frequency or wirelessly. A device or person who transmits data is the sender, while the computer that receives the data is referred to as the receiver. In a data communications network more than two computers can Homepage be involved in the communication process.
Multiplexing and Demultiplexing are two communication technologies that optimize bandwidth usage and cut costs. Both of these processes require special hardware that is able to combine and then separate these signals. This function is typically performed by custom integrated circuits, which are present in a wide range of communication devices such as cellphones, computers, and printers.
The data communication mode that allows simultaneous two-way communication between a pair of devices is known as full-duplex communications. This type of communication is more complicated than simplex transmission as it requires the ability of sending and receiving data at the same time.
