  3. Real-time computing - Wikipedia

    en.wikipedia.org/wiki/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]

  4. Comparison of open-source and closed-source software

    en.wikipedia.org/wiki/Comparison_of_open-source...

    [8] [9] [10] The cost of making a copy of a software program is essentially zero, so per-use fees are perhaps unreasonable for open-source software. At one time, open-source software development was almost entirely volunteer-driven, and although this is true for many small projects, many alternative funding streams have been identified and ...

  6. Real-time operating system - Wikipedia

    en.wikipedia.org/wiki/Real-time_operating_system

    A "hard" real-time operating system (hard RTOS) has less jitter than a "soft" real-time operating system (soft RTOS); a late answer is a wrong answer in a hard RTOS while a late answer is acceptable in a soft RTOS. The chief design goal is not high throughput, but rather a guarantee of a soft or hard performance category.
