Real-time computing ( RTC) is the computer science term for hardware and software systems subject to a "real-time constraint", for example from event to system response. [1] Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines". [2]
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 ...
Real-time data can be dynamic (e.g. a variable indicating current location) or static (e.g. a fresh log entry indicating location at a specific time). In economics [ edit ] Real-time economic data, and other official statistics , are often based on preliminary estimates, and therefore are frequently adjusted as better estimates become available.
Real time (media) Real time within the media is a method in which events are portrayed at the same rate at which they occur in the plot. For example, if a film told in real time is two hours long, then the plot of that movie covers two hours of fictional time. If a daily real time comic strip runs for six years, then the characters will be six ...
Real-time computer graphics or real-time rendering is the sub-field of computer graphics focused on producing and analyzing images in real time. The term can refer to anything from rendering an application's graphical user interface ( GUI ) to real-time image analysis , but is most often used in reference to interactive 3D computer graphics ...
A real-time operating system ( RTOS) is an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints. An RTOS is distinct from a time-sharing operating system, such as Unix, which manages the sharing of system resources with a scheduler, data buffers, or fixed task ...
Real-time communication (RTC) is a category of software protocols and communication hardware media that gives real-time guarantees, which is necessary to support real-time guarantees of real-time computing. [1] Real-time communication protocols are dependent not only on the validity and integrity of data transferred but also the timeliness of ...
Real-time web. The real-time web is a network web using technologies and practices that enable users to receive information as soon as it is published by its authors, rather than requiring that they or their software check a source periodically for updates.
