Data communication is vital for our digital world. It connects us to the devices and services that we rely on. It encompasses a range of methods and technologies that determine how information is transferred from one end to another. Understanding how it works allows us to design an efficient and reliable networks that offer the benefits of greater connectivity for increased efficiency and productivity in business as well as innovations in automation.
Data communication is the transfer of data between computers via the medium or channel. This could be accomplished via wire cables, satellite signal, radio frequency, or wirelessly. The sender is the person or device transmitting data, and the receiver is the device that receives the data. In a network of data communication, more than two computers may be involved in the communication process.
Multiplexing and Demultiplexing are communication techniques that optimize bandwidth use and cut costs. Both processes require special hardware able to combine and then separate these signals. Custom integrated circuits are commonly used to perform this function and can be found in various bigdataroom.net communications devices including cellphones, computers, and printers.
Full-duplex communication is the mode of data communication that permits 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 simultaneously.
