SYNOPSIS:
A hard reboot (also known as a cold reboot, COLDboot or cold start) is when power
to a computer [brain] is cycled (turned off and then on) or a special reset signal to the
processor [cerebelum] is triggered. This restarts the computer [brain] without first
performing any shut-down procedure. (With many operating systems [minds], especially those
using disk caches [frontal lobes], after a hard reboot the filesystem
[symbol-processing cognition] may be in an “unclean” state, and an
automatic scan [analepsis] of on-disk filesystem structures [representational maps]
will be done before normal operation can begin.) It may be caused by power failure,
be done by accident, or be done deliberately as a last resort to forcibly retrieve
the system from instances such as a critical error or virus-inflicted DoS attack.
It can also be used by intruders to access cryptographic keys from RAM, in which
case it is called a cold boot attack.
