Data communication is crucial to our modern world. It connects us to the devices and services we rely on. It encompasses a range of methods and media that dictate how information is transferred from one end to another. Understanding how it works allows us to design a highly efficient and reliable networks that offer the benefits of a greater network like improved business efficiencies and productivity as well as innovations in automation.
The fundamental concept behind data communication is the transmission of data from one computer to another via a channel or medium. This can be accomplished via the use of a wire cable, satellite signal, radio frequency or wirelessly. A device or individual who transmits data is referred to as the sender and the computer which receives the data is referred to as the receiver. A data communications network may include more than two computers involved in the process of communication.
Multiplexing and demultiplexing are useful technology for communication that allows multiple signals to be transmitted over the same medium at the same time, maximizing the bandwidth used and reducing costs. Both of these methods require specialized hardware that can combine and separate signals. This function is typically performed by custom integrated circuits that are found in a variety of communication devices, such as cell phones, computers and printers.
The data communication mode that allows for simultaneous two-way communication between the same pair of devices is referred to as full-duplex communication. This type of communication is more complex than simplex communication because it requires the ability of sending and receiving https://bigdataroom.net/how-to-block-someone-on-hangouts/ data at the same time.
