Data communication is the key element that connects us with the devices and services we depend on in our interconnected digital world. It encompasses a range of techniques and methods that control how information flows from one end to the next. Understanding how it works helps us to design efficient and reliable networks that offer the benefits of increased connectivity including enhanced efficiency and productivity for businesses and new innovations in automation.
Data communication is the transfer of data between computers through a medium or channel. It can be done via cable, radio frequency, satellite signal, or wirelessly. A device or individual who transmits data is referred to as the sender, while the computer that receives the data is referred www.bigdataroom.net/adobe-premiere-pro-for-free-or-creative-cloud to as the receiver. In a network for data communication more than two computers could be involved in the process of communication.
Demultiplexing and multiplexing are two important communication technologies that allow several signals to be transmitted across an medium at once, thus optimizing the bandwidth used and reducing costs. Both of these processes require special equipment that can combine and separate signals. This is usually done by custom integrated circuits that are found in a wide range of communication products like phones, computers, and printers.
Full-duplex communication is the mode of data communication that allows simultaneous two-way communication between two devices. This mode is more complex than simplex transmission since it requires the ability to transmit and receive data at the same time.
