   check
    n.
       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-guards).
