In the early 80's in IBM tests were being intensively with new hardware and new software. This caused the computers freezes easily. To restarting a computer was necessary switch off, wait a few seconds to rest for to avoid damaging the hardware, restart it and wait for self-test routines that played PC. It took more than a minute to regain the operational team.
The idea of \u200b\u200bDavid J. Bradley, an engineer at IBM, was to create a mechanism to restart "hot" without having to go through that process. The time saving was considerable, and so this functionality, which was initially only intended to be known by the developers of IBM, gradually spread among the public.
