COMPUTER FUNDAMENTALS

Detailed explanation-1: -A hard drive or hard disk drive (HDD) is a type of data storage device that is used in laptops and desktop computers. An HDD is a “non-volatile” storage drive, which means it can retain the stored data even when no power is supplied to the device.

Detailed explanation-2: -Hard Drive Capacity. The amount of storage on a hard disk is measured in gigabytes and terabytes. Hard drive capacity is measured by the amount of data users need to store, which is often much greater than the space applications take up. For example, a single video can take up four gigabytes of space.

Detailed explanation-3: -They were originally called “disk” drives because the files were recorded on round things called “disks.” “Floppy” disks kept the information on a very thin, round piece of spinning material about the thickness of a piece of paper, and were about 3-1/2, 5-1/4 or 8 inches in diameter.

Detailed explanation-4: -Hard Disk Drive (HDD) Hard disk drives are non-volatile magnetic storage devices capable of remembering vast amounts of data. An electromagnet in the read/write head charges the disk’s surface with either a positive or negative charge, this is how binary 1 or 0 is represented.
