Real-time computing. 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 data. Real-time data (RTD) is information that is delivered immediately after collection. There is no delay in the timeliness of the information provided. Real-time data is often used for navigation or tracking. [1] Such data is usually processed using real-time computing although it can also be stored for later or off-line data analysis.
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 operating system. 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 ...
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 ...
A collaborative real-time editor is a type of collaborative software or web application which enables real-time collaborative editing, simultaneous editing, or live editing of the same digital document, computer file or cloud-stored data – such as an online spreadsheet, word processing document, database or presentation – at the same time by different users on different computers or mobile ...
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. Static and conventional methods of testing can detect ...
CPU time (or process time) is the amount of time for which a central processing unit (CPU) was used for processing instructions of a computer program or operating system, as opposed to elapsed time, which includes for example, waiting for input/output (I/O) operations or entering low-power (idle) mode. The CPU time is measured in clock ticks or ...
