Understanding your audience is essential to effective data communication. You can accomplish this by creating visuals that are engaging and convey information. Effective data communication could involve using the appropriate words to convey the information.
The basic definition of data communication is the transfer of data from one computer to another via a network or other medium. The information can be anything from a simple text message to an audio file or Hyperlink. The data can be transmitted wirelessly or via wired medium. In order for two computers to communicate with each other, they need a method of linking together which is called a network or channel.
Modern networks for data communications employ several data transmission channels. These include duplex, simplex and full-duplex. Simplex mode allows information to flow in only one direction at a time whereas duplex mode allows both sender and receiver to transmit simultaneously. Full-duplex mode works similarly to duplex but it requires that both the transmitter and receiver be synchronized for them to correctly read individual binary data bits of the signal that is transmitted.
The information that is transmitted via an electronic data communication channel can either be digital messages sent by a microprocessor or an analog signal (such as phone calls or video) that has been digitalized using pulse-code modulation. To ensure that the receiver receives the correct information, any errors in data transmission must be spotted and corrected. This is typically accomplished with the use of sequence numbers and acknowledgement codes.
