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.

Videoconferencing and Gaming
Videoconferencing requires real-time systems that can transmit video across the network and display it at the other end as quickly as the camera is recording it. Gaming is another real-time application. The system must respond to the user's inputs and render video frames on screen fast enough to simulate realistic motion.

Business Systems - Not Really
The typical transaction processing system is not considered real time even though it does update 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.

Papers address topics in the research, development, and design of embedded systems, including embedded systems in architecture, software, hardware, real-time computing, testing and verification, image and graphics processing, hardware/software co-design, pervasive/ubiquitous computing, wireless sensor networks, power-aware computing, security and dependability, system on chip (SoC) and multi-core based systems, and embedded multimedia systems.
This latest support for real-time computing on Linux is the result of years of contributions to the open-source community by SGI, which has consistently identified hold-offs and submitted kernel modifications that, once accepted into the Linux kernel, have resulted in better latencies.
BlueStep's configurable software gives customers the Internet infrastructure to deliver information, manage projects, and share real-time computing power across an organization--regardless of complexity, size, or location.
