Definition of Data Communications

Data communications refers to sending digital messages using communication technology. Communication technology used in data communications includes wires, optic fibers, and radio frequencies. In the United States, the Federal Communications Commission regulates radio frequencies used in data communications.

Significance

The data communications field explores communication technology's technical aspects to determine potential advancement. This entails analyzing communication technology theories and determining if the theories would prove practical when considering real-life restrictions.

Function

Purdue University explains data communications tests communication technology practicality using math, physics, and electrical engineering. Electrical engineering focuses on turning a message digital. Math and physics help determine if the digital messages can be transmitted through a given communication medium, such as cables or radio frequencies.

Troubleshooting

Poorly placed equipment and interference can create data communications difficulties. For example, a router placed at one end of an office will cause weaker wireless Internet connections for workers on the office's other side. Wireless Internet connection problems could also indicate the need to change radio frequencies to a less trafficked radio frequency channel.
