  2. Timeout Detection and Recovery - Wikipedia

    en.wikipedia.org/wiki/Timeout_Detection_and_Recovery

    Timeout Detection and Recovery or TDR is a feature of the Windows operating system (OS) introduced in Windows Vista. It detects response problems from a graphics card (GPU), and if a timeout occurs, the OS will attempt a card reset to recover a functional and responsive desktop environment .

  3. Watchdog timer - Wikipedia

    en.wikipedia.org/wiki/Watchdog_timer

    For example, a watchdog timer may be used when running untrusted code in a sandbox, to limit the CPU time available to the code and thus prevent some types of denial-of-service attacks. [2] In real-time operating systems , a watchdog timer may be used to monitor a time-critical task to ensure it completes within its maximum allotted time and ...

  4. Blue screen of death - Wikipedia

    en.wikipedia.org/wiki/Blue_screen_of_death

    Preview builds of Windows 10, Windows 11, and Windows Server (available from the Windows Insider program) feature a dark green background instead of a blue one. [26] [27] [24] Windows 3.1, 95, and 98 supports customizing the color of the screen [28] whereas the color is hard-coded in the Windows NT family. [28]

  5. Polling (computer science) - Wikipedia

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

    A poll message is a control-acknowledgment message.. In a multidrop line arrangement (a central computer and different terminals in which the terminals share a single communication line to and from the computer), the system uses a master/slave polling arrangement whereby the central computer sends message (called polling message) to a specific terminal on the outgoing line.

  6. Real-time clock alarm - Wikipedia

    en.wikipedia.org/wiki/Real-time_clock_alarm

    A real time clock alarm is a feature that can be used to allow a computer to 'wake up' after shut down to execute tasks every day or on a certain day. It can sometimes be found in the 'Power Management' section of a motherboard 's BIOS / UEFI setup.

  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. Clock recovery - Wikipedia

    en.wikipedia.org/wiki/Clock_recovery

    Clock recovery addresses this problem by embedding clock information into the data stream, allowing the transmitter's clock timing to be determined. This normally takes the form of short signals inserted into the data that can be easily seen and then used in a phase-locked loop or similar adjustable oscillator to produce a local clock signal ...

  9. Time Stamp Counter - Wikipedia

    en.wikipedia.org/wiki/Time_Stamp_Counter

    The Time Stamp Counter was once a high-resolution, low-overhead way for a program to get CPU timing information. With the advent of multi-core/hyper-threaded CPUs, systems with multiple CPUs, and hibernating operating systems, the TSC cannot be relied upon to provide accurate results — unless great care is taken to correct the possible flaws: rate of tick and whether all cores (processors ...
