What is Data Communication?

One of the key aspects of data communication is knowing your audience and creating visualizations that convey information in a captivating manner. Effective data communication may also be achieved by using the right words to deliver the information.

Data communication is defined as the transfer of data from one computer to the other via the internet, or through any other method. Information can range from a simple audio file to an SMS message. The data can be sent wirelessly or through wired media. For two computers to be capable of communicating they must have a means to connect. This is referred to as a channel or network.

There are a variety of data transmission channels utilized in modern networks for data communication. There are three types of data transmission channels: simplex, full-duplex, and duplex. Simplex mode allows information to flow only in one direction, whereas duplex mode allows the transmitter and receiver to transmit simultaneously. Full-duplex mode is similar to duplex, but it requires that the transmitter and receiver be synchronized in order for them to properly read the individual binary data bits on the signal transmitted.

The information that is transmitted through a data communications channel could be digital messages that are sent by microprocessors or analog signal like the phone call or video footage that has been transformed into a series of binary bits using https://bigdataroom.net/how-to-recover-a-corrupt-word-or-zip-file/ pulse-code modulation. Any mistakes in the transmission of data should be identified and rectified to ensure that only correct information is received by the receiver at the other end. This is usually done using a combination sequence numbers and acknowledgement codes.
