Detailed explanation-2: -A PC’s power supply produces +3.3VDC, +5VDC, –5VDC, +12VDC, and –12VDC from a 110VAC input.
Detailed explanation-3: -A hybrid hard drive (HHD), sometimes known as a solid-state hybrid drive (SSHD), is a mass storage device that combines a conventional hard disk drive (HDD) and a NAND flash module. An HHD blends the capacity, cost and performance of physical disk storage with the accelerated performance of flash.
Detailed explanation-4: -Although many storage administrators are now choosing disk as the media of choice for backups, tape storage media remains the most widely used archive media mostly because of its cost-to-capacity ratio, but also due to a very broad and well-established implementation base.
Detailed explanation-5: -Hard drives and optical drives commonly use +5 and +12 volts.
