Understanding your audience is essential to a successful 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 defined as the transfer of data from one computer to another through a network, or any other method. The information can be anything from an ordinary text message to an audio file or Hyperlink. The medium used to transmit data could be wired or wireless. For two computers to communicate with one other they must have a method of linking together which is known as a channel or channel.

There are various types of data transmission channels used in modern networks for data communications. These include simplex, duplex and full-duplex. Simplex mode allows information to flow only in one direction, while duplex mode allows the transmitter and receiver both to transmit simultaneously. Full-duplex is similar to duplex however, it requires that both the receiver and transmitter be synchronized to read the binary data bits of the signal being transmitted.

The data that is transmitted over a data communications channel can be either digital messages transmitted by microprocessors or analog signal, such as a telephone call or video image that has been digitalized into a sequence of binary bits using pulse-code modulation. To ensure that the receiver is receiving the correct information, errors in data transmission must be identified and rectified. This is usually done using a combination of sequence numbers and acknowledgement codes.
