This is a list of real-time operating systems (RTOSs). This is an operating system in which the time taken to process an input stimulus is less than the time lapsed until the next input stimulus of the same type.
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.
Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines". [2] The term "real-time" is also used in simulation to mean that the simulation's clock runs at the same speed as a real clock. Real-time responses are often understood to be in the order of milliseconds, and sometimes microseconds.
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 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 database has two meanings. The most common use of the term refers to a database system which uses streaming technologies to handle workloads whose state is constantly changing. [ 1 ] This differs from traditional databases containing persistent data , mostly unaffected by time.
It can be defined as either the most complex or the newest technology on the market. [3] The opposite of high tech is low technology, referring to simple, often traditional or mechanical technology; for example, a slide rule is a low-tech calculating device. [4] [5] [6] When high tech becomes old, it becomes low tech, for example vacuum tube ...
Real time means near to zero latency and access to information whenever it is required. [1] The speed of today's processing systems has allowed typical data warehousing to work in real-time. The result is real-time business intelligence. Business transactions as they occur are fed to a real-time BI system that maintains the current state of the ...
