Communications is the exchange of information and ideas. This can be achieved in several ways, by sight, sound or touch. Numerous technologies have been developed to allow communications over distances and between different standards.

The disruption of communications can be problematic, but can also be useful in warning others. For instance, when disaster struck an archaeological expedition on Rajatha Prime the lack of communications from the planet altered the USS Enterprise-D, allowing it to arrive at the planet in time to rescue Jean-Luc Picard.
