37. Four Main Parts of the boot process: 1. BIOS checks hardware through POST. 2. The ___________ searches for and loads an OS. 3. The OS configures the system and completes its own loading. 4. The user executes application software.






38. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






39. A computer's ability to respond to a fault or catastrophe - such as a hardware failure or power outage - so that data is not lost.
