real time

As fast as required. A real-time system must respond to a signal, event or request fast enough to satisfy some requirement. Real time often refers to process control and embedded systems. For example, space flight computers must respond to changing conditions in order to keep the rocket ship on course. Industrial robots must respond quickly in order to keep the assembly line moving at full speed. Antilock brakes and other driving assist systems must respond to changing road conditions immediately in order to benefit the driver and vehicle. See embedded system, real-time audio, real-time video and real-time search.

Real-Time Communications
Videoconferencing requires real-time systems that transmit video across the network and display it at the other end as quickly as the camera is capturing it. Gaming is another real-time application. The system must render video frames in immediate response to the user's inputs.

Business Systems - Not Really
The typical transaction processing system is not considered real time even though it often updates databases immediately. However, in the past, as business information systems became fast enough to respond to queries and updates in only a second or two, they were called real-time systems. See online.

Asked what benefits their agencies gain from using real-time tools, 78 percent of respondents said "saves many keystrokes" and 71 percent described real time as a "significant time-saver for staff." Participants also identified ease of use (71 percent), faster/instant customer response (68 percent), the ability to quote more business faster (47 percent), freeing up more time for sales and service (47 percent), and greater accuracy (45 percent) as benefits.

Of course, that changed with the phenomenal rise of Twitter over the past few years because Twitter allows people to share in real time.
