What is Data Communication?


Understanding your target audience is crucial to effective data communication. You can achieve this by creating visuals that are engaging and convey information. Effective data communication may involve using the correct words to convey the information.

Data communication is the transfer of data from one computer to the other via the network, or any other medium. Information can range from a simple audio file to a text message. The data can be sent wirelessly or through wired medium. In order for two computers to be capable of communicating, they require a means of connecting together. This is known as a channel or network.

There are many types of data transmission channels that are used in modern networks for data communication. There are three types of data transmission channels: simplex full-duplex and duplex. Simplex mode only allows information to flow in one direction at a given time while duplex mode allows both receiver and sender to transmit at the same time. Full-duplex mode is comparable to duplex, however it requires that the receiver and transmitter be synchronized for them to read the correct binary data bits of the transmitted signal.

Information that is transmitted using a data communication channel may be either digital data sent by a microprocessor or an analog signal (such as phone calls or www.bigdataroom.net video) that has been digitalized using pulse-code modulation. To ensure that the receiver gets the correct information, any errors in data transmission have to be detected and corrected. This is usually done through the use of sequence numbers and acknowledgement codes.
