  2. Busy waiting - Wikipedia

    en.wikipedia.org/wiki/Busy_waiting

    In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available. Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a ...

  3. Keyboard interrupt - Wikipedia

    en.wikipedia.org/wiki/Keyboard_interrupt

    In computing, keyboard interrupt may refer to: A special case of signal (computing) , a condition (often implemented as an exception) usually generated by the keyboard in the text user interface A hardware interrupt generated when a key is pressed or released, see keyboard controller (computing)

  4. Signal (IPC) - Wikipedia

    en.wikipedia.org/wiki/Signal_(IPC)

    Ctrl-C (in older Unixes, DEL) sends an INT signal ("interrupt", SIGINT); by default, this causes the process to terminate. Ctrl-Z sends a TSTP signal ("terminal stop", SIGTSTP); by default, this causes the process to suspend execution. [4] Ctrl-\ sends a QUIT signal ; by default, this causes the process to terminate and dump core.

  5. Exception handling (programming) - Wikipedia

    en.wikipedia.org/wiki/Exception_handling...

    Another feature is a semi-asynchronous mechanism that raises an asynchronous exception only during certain operations of the program. For example, Java's Thread. interrupt only affects the thread when the thread calls an operation that throws InterruptedException. [53]

  6. Keyboard controller (computing) - Wikipedia

    en.wikipedia.org/wiki/Keyboard_controller...

    In computing, a keyboard controller is a device that interfaces a keyboard to a computer. Its main function is to inform the computer when a key is pressed or released. When data from the keyboard arrives, the controller raises an interrupt (a keyboard interrupt) to allow the CPU to handle the input.

  7. Hooking - Wikipedia

    en.wikipedia.org/wiki/Hooking

    Function hooking is implemented by changing the very first few code instructions of the target function to jump to an injected code. Alternatively on systems using the shared library concept, the interrupt vector table or the import descriptor table can be modified in memory. Essentially these tactics employ the same ideas as those of source ...

  8. Exception handling syntax - Wikipedia

    en.wikipedia.org/wiki/Exception_handling_syntax

    Exception handling syntax is the set of keywords and/or structures provided by a computer programming language to allow exception handling, which separates the handling of errors that arise during a program's operation from its ordinary processes.

  9. Fast interrupt request - Wikipedia

    en.wikipedia.org/wiki/Fast_interrupt_request

    Fast interrupt request (FIQ) is a specialized type of interrupt request, which is a standard technique used in computer CPUs to deal with events that need to be processed as they occur, such as receiving data from a network card, or keyboard or mouse actions.
