Real-time
Real-time or real time describes various operations in computing or other processes that must guarantee response times within a specified time (deadline), usually a relatively short time. A real-time process is generally one that happens in defined time steps of maximum duration and fast enough to affect the environment in which it occurs, such as inputs to a computing system.
Examples of real-time operations include:
Computing
- Real-time computing, hardware and software systems subject to a specified time constraint
- Real-time clock, a computer clock that keeps track of the current time
- Real-time Control System, a reference model architecture suitable for software-intensive, real-time computing
- Real-time Programming Language, a compiled database programming language which expresses work to be done by a particular time
Applications
- Real-time computer graphics, sub-field of computer graphics focused on producing and analyzing images in real time
- Real-time camera system, for controlling cameras in a 3D virtual environment
- Real-time operating system, for running real-time software
- Real-time protection, protection enabled constantly, rather than by, say, a virus scan
- Real-time text, transmitted as it is being typed or produced
- Real time Java, for real-time programs in Java
- Real-time disk encryption, encrypting data as it is written to disk
- Real-time web, whereby information is sent to users as it becomes available
- Live streaming, continuously delivering multimedia in real time
- Collaborative real-time editor, simultaneous editing of a document by several users
- Real-time simulation, simulation able to run at the same rate as reality
- Real-time Blackhole List, a DNS blacklist
- Real-time Cmix, a music programming language
- Real Time AudioSuite, an audio plug-in for Pro Tools
Other science and technology
- Real-time locating system, a system used to automatically identify and track the location of objects or people in real time
- Real-time gross settlement, an online system for settling financial transactions
- Real-time kinematic, a satellite navigation technique
- Real-time polymerase chain reaction, a laboratory technique which monitors target DNA during the PCR
