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 ...
Command Loss Timer Reset systems involve both hardware and software. Most spacecraft have more than one Command Loss Timer Reset for subsystem level safety reasons, with the Voyager craft using at least 7 of these timers. Technically the Command Loss Timer Reset is a glorified array of Watchdog timers, each with different settings.
STONITH ("Shoot The Other Node In The Head" or "Shoot The Offending Node In The Head"), sometimes called STOMITH ("Shoot The Other Member/Machine In The Head"), is a technique for fencing in computer clusters. [1] Fencing is the isolation of a failed node so that it does not cause disruption to a computer cluster. As its name suggests, STONITH ...
On some systems, a computer user can trigger an NMI through hardware and software debugging interfaces and system reset buttons. Programmers typically use debugging NMIs to diagnose and fix faulty code. In such cases, an NMI can execute an interrupt handler that transfers control to a special monitor program. From this program, a developer can ...
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.

A modern PC with a bus rate of around 1 GHz and a 32-bit bus might be 2000x or even 5000x faster, but might have many more gigabytes of memory. With boot times more of a concern now than in the 1980s, the 30- to 60-second memory test adds undesirable delay for a benefit of confidence that is not perceived to be worth that cost by most users.
Not so long ago, this league was Kentucky, Florida and a bunch of minnows. Now, as Calipari said last week, “It doesn’t matter who you play. You can lose.”
