A hardware-detected error condition, most commonly used to refer to
actual hardware failures rather than software-induced traps. E.g., a
parity check is the result of a hardware-detected parity error.
Recorded here because the word often humorously extended to
non-technical problems. For example, the term child check has been
used to refer to the problems caused by a small child who is curious
to know what happens when s/he presses all the cute buttons on a
computer's console (of course, this particular problem could have
been prevented with {molly-guard}s).
