What is Data Communication?

The most important aspect of data communication is understanding your target audience and creating visuals that convey information in a compelling way. Effective data communication can involve using the right words to convey that information.

A fundamental definition of data communication is the transfer of information from one computer to another over the internet or another medium. The information can be anything from an ordinary text message to an audio file or Hyperlink. The data can be sent wirelessly or by wired medium. For two computers to communicate with each another, they must have a method of linking together which is referred to as a network or channel.

There are many types of data transmission channels that are utilized in modern networks for data communication. There are three kinds of data transmission channels: simplex full-duplex and duplex. Simplex mode permits information to flow only in one direction, whereas duplex mode allows both the sender and receiver to transmit simultaneously. Full-duplex mode is similar to duplex but it requires that the receiver and transmitter be synchronized to allow them to properly read the individual binary data bits of the transmitted signal.

Information transmitted through the data communication channel could be either digital data sent by a microprocessor, or an analog signal (such as phone calls or video) that has been converted into digital using pulse-code modulation. To ensure that the receiver receives only the correct information, errors in data transmission have to be detected www.bigdataroom.net/how-to-recover-a-corrupt-word-or-zip-file and rectified. This is usually done using a combination of sequence numbers and acknowledgement codes.
