  2. Real-time computing - Wikipedia

    en.wikipedia.org/wiki/Real-time_computing

    Soft real-time systems are typically used to solve issues of concurrent access and the need to keep a number of connected systems up-to-date through changing situations. Some examples of soft real-time systems: Software that maintains and updates the flight plans for commercial airliners. The flight plans must be kept reasonably current, but ...

  3. Multithreading (computer architecture) - Wikipedia

    en.wikipedia.org/wiki/Multithreading_(computer...

    Conceptually, it is similar to cooperative multi-tasking used in real-time operating systems, in which tasks voluntarily give up execution time when they need to wait upon some type of event. This type of multithreading is known as block, cooperative or coarse-grained multithreading.

  4. Comparison of real-time operating systems - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_real-time...

    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.

  5. Computer multitasking - Wikipedia

    en.wikipedia.org/wiki/Computer_multitasking

    In general, memory access management is a responsibility of the operating system kernel, in combination with hardware mechanisms that provide supporting functionalities, such as a memory management unit (MMU). If a process attempts to access a memory location outside its memory space, the MMU denies the request and signals the kernel to take ...

  6. Real-time business intelligence - Wikipedia

    en.wikipedia.org/wiki/Real-time_business...

    Real-time business intelligence (RTBI) is a concept describing the process of delivering business intelligence (BI) or information about business operations as they occur. 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 ...

  7. Concurrency (computer science) - Wikipedia

    en.wikipedia.org/wiki/Concurrency_(computer_science)

    For example, Lee and Sangiovanni-Vincentelli have demonstrated that a so-called "tagged-signal" model can be used to provide a common framework for defining the denotational semantics of a variety of different models of concurrency, [11] while Nielsen, Sassone, and Winskel have demonstrated that category theory can be used to provide a similar ...

  8. Real-time database - Wikipedia

    en.wikipedia.org/wiki/Real-time_database

    Such real-time databases are useful for assisting social media platforms in the removal of fake news, in-store surveillance cameras identifying potential shoplifters by their behavior/movements, etc. The second meaning of the term “real-time database” adheres to a stricter definition of real-time consistent with Real-time computing. Hard ...

  9. Concurrent computing - Wikipedia

    en.wikipedia.org/wiki/Concurrent_computing

    For example, concurrent processes can be executed on one core by interleaving the execution steps of each process via time-sharing slices: only one process runs at a time, and if it does not complete during its time slice, it is paused, another process begins or resumes, and then later the original process is resumed. In this way, multiple ...
