Understanding your target audience is crucial to effective data communication. You can accomplish this by creating visuals that are compelling and convey information. Effective data communication may also require the use of the right words to deliver the information.
Data communication is the transfer of data from one computer to the other via the network, or any other method. The information can range from simple text messages to an audio file or Hyperlink. The data can be sent wirelessly or via wired medium. To be see it here capable of communicating they require a method of connecting together. This is called a channel or network.
There are various types of data transmission channels that are used in modern networks for data communications. These include simplex, duplex and full-duplex. Simplex mode permits information to flow only in one direction, while duplex mode permits the sender and receiver both to transmit simultaneously. Full-duplex is similar to duplex but requires that both the receiver and the transmitter be at a synchronized state to read binary data bits in the signal being transmitted.
Information transmitted through a data communication channel may be digital messages sent by a microprocessor or an analog signal (such as a video or telephone call) that is digitalized by using pulse-code modulation. Any errors in the transmission of data must be detected and rectified to ensure only correct information is received by the receiver at the other end. This is usually accomplished through a combination of sequence numbers and acknowledgement codes.
