The Basics of Data Communication

Data communication is vital to our digital age. It connects us with the devices and services we rely on. It is comprised of a variety of techniques and media which dictate how information flows from one end to another. Understanding how it works allows us to design efficient and reliable networks that can provide the benefits of increased connectivity, such as improved efficiency and productivity of businesses and advancements in automation.

The principle of data communication is the transmission of data from one computer to another via channels or mediums. This can be done via cables, satellite signal, radio frequency or wirelessly. A person or device that transmits data is the sender and the computer which receives the data is known as the receiver. In a network for data communication, more than two computers can be www.bigdataroom.net involved in the process of communication.

Demultiplexing and multiplexing are both useful communication technologies that permit multiple signals to be transmitted across an medium at once, thus optimizing the use of bandwidth and reducing costs. Both of these processes require special hardware able to combine and then separate these signals. This task is typically carried out by custom integrated circuits which are found in a variety of communication products including cell phones, computers and printers.

The mode of data communication that allows simultaneous two-way communication between the same pair of devices is referred to as full-duplex communication. This mode is more complicated than simplex transmission, since it requires the capability to send and receive data simultaneously.
