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 ...
Automatic system recovery is a device or process that detects a computer failure and attempts recovery. The device may make use of a Watchdog timer. This may also refer to a Microsoft recovery technology by the same name.
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 .
Network timeout preventing a Web browser from loading a page. In telecommunications and related engineering (including computer networking and programming), the term timeout or time-out has several meanings, including: A network parameter related to an enforced event designed to occur at the conclusion of a predetermined elapsed time.
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
The top U.S. cyber watchdog agency issued an emergency directive Friday, mandating that all federal agencies protect themselves against a dangerous vulnerability in a popular software program. The ...
This can destroy real-time behavior and cause clock ticks to get lost. The Windows and Linux kernels define an "SMI Timeout" setting – a period within which SMM handlers must return control to the operating system, or it will "hang" or "crash". The SMM may disrupt the behavior of real-time applications with constrained timing requirements.
In spacecraft, a Command-Loss Timer (CLT) is a software timer within the command and data system (CDS) which is restarted every time the spacecraft receives a command from Earth. [1] If the CLT times out , it is assumed that the spacecraft's receiver has failed to reliably receive messages and, in response, the CDS will attempt to restore ...
