What is Data Communication?

Understanding your audience is the key to a successful data communication. It is possible to do this by designing visuals that are appealing and convey information. Effective data communication may involve using the appropriate words to convey the information.

Data communication is defined as the transfer of information from one computer to another via a network, or any other type of medium. Information could range from a simple audio file to text messages. The medium used for transmission of data can be wired or wireless. In order for two computers to communicate with each other, they need an option of linking which is known as a channel or channel.

There are several types of data transmission channels that are utilized in modern networks for data communications. There are three kinds of data transmission channels: simplex, full-duplex, and duplex. Simplex mode only allows information to flow in one direction at a time whereas duplex mode allows both the sender and receiver to transmit simultaneously. Full-duplex is similar to duplex however, it requires that both the transmitter and the receiver be in sync to read the binary data bits of the transmitted signal.

The information transmitted through a data communications channel can be either digital messages www.bigdataroom.net/adobe-premiere-pro-for-free-or-creative-cloud sent from microprocessors or analog signal like an audio or video images that have been digitized into a series of binary bits using pulse-code modulation. To ensure that the receiver receives the correct data, any mistakes in data transmission should be spotted and corrected. This is usually done using a combination of sequence numbers and acknowledgement codes.
