Understanding your audience is the key to effective data communication. You can accomplish this by creating visuals that are compelling and convey information. Effective data communication could involve using the appropriate words to convey the information.

Data communication is the transfer of data from one computer ZIP archive recovery process to another through a network, or any other method. Information could range from a simple audio file to an SMS message. The medium used to transmit data could be wireless or wired. For two computers to be capable of communicating they must have a means of connecting together. This is called a channel or network.

Modern networks for data communication use several data transmission channels. There are three kinds of data transmission channels: simplex full-duplex and duplex. Simplex mode lets information flow only in one direction, while duplex mode permits the sender and receiver both to transmit simultaneously. Full-duplex is similar to duplex, however, it requires both the receiver and transmitter are in sync to read the binary data bits in the transmitted signal.

The data transmitted over a data communications channel can be either digital messages generated by microprocessors or analog signal, like the phone call or video images that have been converted into a sequence of binary bits using pulse-code modulation. To ensure that the receiver receives the correct information, any errors in the transmission of data must be detected and rectified. This is usually done using a combination of sequence numbers and acknowledgement codes.
