  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. Event-driven programming - Wikipedia

    en.wikipedia.org/wiki/Event-driven_programming

    In addition to writing the event handlers, event handlers also need to be bound to events so that the correct function is called when the event takes place. For UI events, many IDEs combine the two steps: double-click on a button, and the editor creates an (empty) event handler associated with the user clicking the button and opens a text ...

  4. Watchdog timer - Wikipedia

    en.wikipedia.org/wiki/Watchdog_timer

    A watchdog timer (WDT, or simply a watchdog), sometimes called a computer operating properly timer (COP timer), [1] is an electronic or software timer that is used to detect and recover from computer malfunctions. Watchdog timers are widely used in computers to facilitate automatic correction of temporary hardware faults, and to prevent errant ...

  5. Database trigger - Wikipedia

    Column-level trigger: This gets executed before or after the specified column changes. For each row type: This trigger gets executed once for each row of the result set affected by an insert/update/delete. For each statement type: This trigger gets executed only once for the entire result set, but also fires each time the statement is executed.

  6. Bidirectional text - Wikipedia

    en.wikipedia.org/wiki/Bidirectional_text

    Bidirectional script support is the capability of a computer system to correctly display bidirectional text. The term is often shortened to "BiDi" or "bidi".Early computer installations were designed only to support a single writing system, typically for left-to-right scripts based on the Latin alphabet only.

  7. Scroll Lock - Wikipedia

    en.wikipedia.org/wiki/Scroll_Lock

    Pressing the Scroll Lock key in the Linux console while the text is scrolling through the screen freezes the console output (but not input) during which no further text is sent to the screen, while the program continues running as usual, or become blocked at the write syscall when too much data prevented from reaching the terminal caused the tty's output queue to become full and the tty file ...

  8. High Precision Event Timer - Wikipedia

    en.wikipedia.org/wiki/High_Precision_Event_Timer

    The High Precision Event Timer (HPET) is a hardware timer available in modern x86-compatible personal computers. Compared to older types of timers available in the x86 architecture, HPET allows more efficient processing of highly timing-sensitive applications, such as multimedia playback and OS task switching .

    When triggered, it will begin to embed itself in other documents and templates. It may corrupt other parts of the system, depending on what resources a macro in this application can access. When the infected documents are shared with other users and systems, the virus spreads.
