Understanding your audience is essential to a successful data communication. You can do this by creating images that are captivating and convey information. Effective data communication may also be achieved by using the right words to convey the information.
A basic definition of data communication is the transfer of data from one computer to another through networks or other media. The data can range from simple audio file to the form of a text message. The medium used for transmission of data can be wireless or wired. To allow two computers to communicate with each another, they must have an approach to linking that is known as a network or channel.
There are several types of data transmission channels utilized in modern networks for data communications. There are three kinds of data transmission channels: simplex full-duplex and duplex. Simplex mode allows data to flow only in one direction, whereas duplex mode allows the transmitter and receiver to transmit simultaneously. Full-duplex is similar to duplex but requires that both the transmitter and the receiver be synchronized to read the binary data bits in the transmitted signal.
Information that is transmitted via the data communication channel could be either digital data sent by a microprocessor or an analog signal (such as telephone calls or a video) that has been converted into digital using pulse-code modulation. Any errors in the transmission data have to be spotted and corrected to ensure that only correct information is received by the receiver at the other end. This is usually accomplished by using a combination of sequence numbers and acknowledgement codes.
