Answer:
a) To store data permanently
Explanation:
A Hard Disk Drive (HDD) is a non-volatile storage device used to store data permanently. It retains data even when the computer is turned off. HDDs store operating systems, programs, files, and documents, making them the primary storage devices in most computers.
Data on an HDD is stored on magnetic disks called platters. These platters rotate, and a read/write head moves over the surface to access or store data. While HDDs are slower than modern Solid-State Drives (SSDs), they offer more storage capacity at a lower cost.
Hard drives are essential for long-term storage in computing, and they are commonly used for backing up data, storing large files, and maintaining a computer’s system and user data.
