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 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".
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 communication systems are generally understood as one of two types: Hard Real-Time (HRT) and Soft Real-Time (SRT). [2] The difference between a hard and soft real-time communication system is the consequences of incorrect operation.
Real-time Control System (RCS) is a reference model architecture, suitable for many software-intensive, real-time computing control problem domains. It defines the types of functions needed in a real-time intelligent control system , and how these functions relate to each other.
Real-time computer graphics systems differ from traditional (i.e., non-real-time) rendering systems in that non-real-time graphics typically rely on ray tracing. In this process, millions or billions of rays are traced from the camera to the world for detailed rendering—this expensive operation can take hours or days to render a single frame.
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.
Real-time testing is the process of testing real-time computer systems. Software testing is performed to detect and help correct bugs (errors) in computer software. Testing involves ensuring not only that the software is error-free but that it provides the required functionality to the user.
