Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which hard drive uses spinning disks to store data?
A
HDD
B
SSD
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Whereas hard disk drives (HDD) use a spinning magnetic disk and a mechanical write head to manipulate data, SSDs use charge in semiconductors. Internal SSDs are installed within computers, while external SSDs are plugged in like external HDDs-frequently to USB 3.0 ports-and serve similar purposes.

Detailed explanation-2: -A hard disk drive (HDD), hard disk, hard drive, or fixed disk, is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.

Detailed explanation-3: -A hard disk drive platter or hard disk is the circular magnetic disk on which digital data is stored in a hard disk drive.

Detailed explanation-4: -The main difference between a solid state drive (SSD) and a hard disk drive (HDD) is how data is stored and accessed. HDDs use mechanical spinning disks and a moving read/write head to access data, while SSDs use memory chips.

Detailed explanation-5: -Data is stored on a hard drive in binary code, using 1s and 0s. The information is spread out on the magnetic layer of the disk(s) and are read or written by the read heads that ‘float’ above the surface thanks to the layer of air produced by the ultra fast rotation of the disk.
