FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -An HDD is a data storage device that lives inside the computer. It has spinning disks inside where data is stored magnetically.

Detailed explanation-2: -The hard drive (sometimes called the hard disk) is the main storage device in your computer. Like RAM, it can be added to and changed, and like ROM it is non-volatile, but it is slow. If you have files and folders on your computer, are stored on the hard drive. The operating system is also stored on the hard drive.

Detailed explanation-3: -The hard drive is where your software, documents, and other files are stored. The hard drive is long-term storage, which means the data is still saved even if you turn the computer off or unplug it. When you run a program or open a file, the computer copies some of the data from the hard drive onto the RAM.

Detailed explanation-4: -Data is copied from the computer’s main memory (random-access memory or RAM), and then written to the hard disk. The drive is the mechanical device that writes the data to the disk.

Detailed explanation-5: -The platter spins with a motor that is connected to the spindle. The chamber also includes the read/write heads that magnetically record information to and from tracks on the platters using a magnetic head. The disks also have a thin magnetic coating on them.
