FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -They can store operating systems, software programs and other files using magnetic disks. More specifically, hard disk drives control the reading and writing of the hard disk that provides data storage. HDDs are used either as the primary or secondary storage device in a computer.

Detailed explanation-2: -Software is typically stored on an external long-term memory device, such as a hard drive or magnetic diskette.

Detailed explanation-3: -A hard disk drive (HDD), hard disk, hard drive, or fixed disk[b] is an electromechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.

Detailed explanation-4: -A hard drive is the hardware component that stores all of your digital content. Your documents, pictures, music, videos, programs, application preferences, and operating system represent digital content stored on a hard drive. Hard drives can be external or internal.

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.
