  2. Time-triggered architecture - Wikipedia

    en.wikipedia.org/wiki/Time-triggered_architecture

    Time-triggered systems can be viewed as a subset of a more general event-triggered (ET) system architecture (see event-driven programming).. Implementation of an ET system will typically involve use of multiple interrupts, each associated with specific periodic events (such as timer overflows) or aperiodic events (such as the arrival of messages over a communication bus at random points in time).

  3. libevent - Wikipedia

    en.wikipedia.org/wiki/Libevent

    libevent is a software library that provides asynchronous event notification. The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. libevent also supports callbacks triggered by signals and regular timeouts.

  4. Event-driven programming - Wikipedia

    en.wikipedia.org/wiki/Event-driven_programming

    Event-driven programming is the dominant paradigm used in graphical user interfaces applications and network servers. In an event-driven application, there is generally an event loop that listens for events and then triggers a callback function when one of those events is detected.

  5. Event (computing) - Wikipedia

    en.wikipedia.org/wiki/Event_(computing)

    In computing, an event is a detectable occurrence or change in the system's state, such as user input, hardware interrupts, system notifications, or changes in data or conditions, that the system is designed to monitor. Events trigger responses or actions and are fundamental to event-driven systems.

  6. Logic bomb - Wikipedia

    en.wikipedia.org/wiki/Logic_bomb

    A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met. For example, a programmer may hide a piece of code that starts deleting files (such as a salary database trigger), should they ever be terminated from the company.

  7. Interrupt - Wikipedia

    en.wikipedia.org/wiki/Interrupt

    A hardware interrupt is a condition related to the state of the hardware that may be signaled by an external hardware device, e.g., an interrupt request (IRQ) line on a PC, or detected by devices embedded in processor logic (e.g., the CPU timer in IBM System/370), to communicate that the device needs attention from the operating system (OS) [7] or, if there is no OS, from the bare metal ...

  8. Retrigger - Wikipedia

    en.wikipedia.org/wiki/Retrigger

    The retrigger effect allows this by calling an event that tells the software to replay the triggered sample at a set rate within the timeframe of the tick on which the event transpires. This ability to circumvent this one rigid limitation of the typical music tracker software has become a staple of the tracker scene, in some cases inspiring ...

  9. Event-driven architecture - Wikipedia

    en.wikipedia.org/wiki/Event-driven_architecture

    An event driven architecture may be built on four logical layers, starting with the sensing of an event (i.e., a significant temporal state or fact), proceeding to the creation of its technical representation in the form of an event structure and ending with a non-empty set of reactions to that event.
