The most important aspect of data communication involves understanding your audience and creating visualizations that convey information in a compelling way. Effective data communication involves using the right words to convey the information.

Data communication refers to the transfer of data from one computer to another through the internet, or through any other form of communication. The information can range from a simple audio file to a text message. The medium used to transmit the data may be wireless or wired. To make two computers able to communicate, they require a means of connecting together. This is known as a channel or network.

There are a variety of data transmission channels that are utilized in modern networks for data communication. There are three kinds of data transmission channels: simplex, full-duplex, and duplex. Simplex mode only permits information to flow in only one direction at once and duplex mode permits both the receiver and sender to transmit simultaneously. Full-duplex is similar to duplex, but requires that both the receiver and transmitter be find more info connected to read the binary data bits in the signal being transmitted.

The data that is sent over a data communication channel can be either digital messages transmitted by microprocessors or analog signal such as phone calls or a video images that have been digitalized into a sequence of binary bits using pulse-code modulation. Any errors in the transmission data must be spotted and rectified to ensure only the correct information is received by the receiver at the other end. This is typically done using a combination of sequence numbers and acknowledgement codes.
