Answer:
Hard disk
Drive
Explanation:
HARD DISK
hard disk, also called hard disk drive or hard drive, magnetic storage medium for a computer. Hard disks are flat circular plates made of aluminum or glass and coated with a magnetic material. Hard disks for personal computers can store terabytes (trillions of bytes) of information. Data are stored on their surfaces in concentric tracks. A small electromagnet, called a magnetic head, writes a binary digit (1 or 0) by magnetizing tiny spots on the spinning disk in different directions and reads digits by detecting the magnetization direction of the spots. A computer’s hard drive is a device consisting of several hard disks, read/write heads, a drive motor to spin the disks, and a small amount of circuitry, all sealed in a metal case to protect the disks from dust. In addition to referring to the disks themselves, the term hard disk is also used to refer to the whole of a computer’s internal data storage. Beginning in the early 21st century, some personal computers and laptops were produced that used solid-state drives (SSDs) that relied on flash memory chips instead of hard disks to store information.
DRIVE
A drive is a location (medium) that is capable of storing and reading information that is not easily removed, like a disk or disc. All drives store files and programs used by your computer. For example, when you write a letter in a word processor, the program is loaded from the hard drive. When you save the document, it's saved to the hard drive or other disk or drive. The picture is an example of different drives listed in Microsoft Windows My Computer.
In the picture, drive A: is the floppy drive, C: is the primary hard drive, D: and E: are partitions, and F: is the CD-ROM drive. The CD-ROM drive is usually the last drive letter. In most situations, the hard drive is the C: drive, and a CD-ROM or other disc drive is the D: drive.
