Understanding your audience is key to a successful data communication. You can do this by creating visuals that are compelling and convey information. Effective data communication could also involve using the right words to convey the information.
Data communication refers to the transfer of data from one computer to another via the network, or any other form of communication. The information can range from a simple audio file to text messages. The data can be sent wirelessly or by wired medium. For two computers to communicate with each other they must have an approach to linking which is referred to as a network or channel.
There are various types of data transmission channels used in modern networks for data communication. These include duplex, simplex and full-duplex. Simplex mode permits information to flow only in one direction, whereas duplex mode permits the sender and receiver to transmit simultaneously. Full-duplex is similar to duplex, however it requires that the receiver and transmitter be synchronized to allow them to properly read the individual binary data bits from the signal being transmitted.
Information transmitted through an electronic data communication channel can be either digital messages transmitted by a microprocessor or an analog signal (such as telephone calls or a video) that has been converted into digital using pulse-code modulation. To ensure that the receiver receives only the correct information, errors in the transmission of data must be spotted and corrected. This is usually accomplished through the use of sequence numbers and acknowledgement codes.
