Understanding your target audience is crucial to a successful data communication. It is possible to do this by designing visuals that are appealing and convey information. Effective data communication also involve using the right words to deliver the information.

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

Modern networks for data communication use various data transmission channels. These include duplex, simplex and full-duplex. Simplex mode allows information to flow in one direction at a given time and duplex mode permits both sender and receiver to transmit simultaneously. Full-duplex is similar to duplex, however, it requires both the receiver and the transmitter be at a synchronized state to read binary data bits of the transmitted signal.

The data transmitted through a data communications channel can be either digital messages that are sent by microprocessors or an analog signal such as an audio or video image that has been converted into a sequence of binary bits using pulse-code modulation. Any errors in the transmission data must be spotted and rectified to ensure that only the correct information is received by the receiver at the other end. This is usually done through a combination of sequence numbers and acknowledgment codes.
