| Archiving |
Process of preserving data over a long period of time and ensuring that it remains accessible and usable. |
| Backup |
Process of copying and storing data in a different location for safekeeping in case of data loss or damage to the original data. |
| Data Mirroring |
Type of data redundancy where two copies of the same data are stored on separate magnetic disks. |
| Data Recovery |
Process of restoring lost or damaged data files from a backup or other copies of the data. |
| Data Redundancy |
Technique of storing duplicates of data to ensure that it is not lost in case of failure or damage to the original data. |
| Data Retention |
Duration for which data has to be preserved and kept accessible. |
| Disk Controller |
Electronic module that manages the flow of data between the computer and the hard disk drive. |
| Hard Disk Drive |
Magnetic storage device that uses several disks coated with magnetic material to store data permanently. |
| IDE |
Interface standard for connecting storage devices such as hard disk drives and CD/DVD drives to a computer's motherboard. |
| Magnetic Storage |
Type of storage that uses magnetic fields to write and read data on a disk or tape. |
| Magnetic Tape |
Long plastic ribbon coated with magnetic material on which data can be magnetically recorded. |
| Platter |
Disk inside a hard disk drive where data is magnetically stored. |
| Read/Write Head |
Component of magnetic storage devices that reads and writes data onto disk by changing magnetic orientation of the disk's surface. |
| Redundant Array Of Independent Disks |
Technology that uses multiple disks to create a single logical unit with improved performance, reliability, and storage capacity. |
| SATA (Serial ATA) |
Interface standard for connecting storage devices such as hard disk drives and solid-state drives to a computer's motherboard. |
| Sector |
Division of a track on a disk containing a fixed number of bytes. |
| Solid-State Drive |
Storage device that uses NAND-based flash memory chips to store data, offering faster access and higher durability than traditional hard disk drives. |
| Tape Drive |
Magnetic storage device that uses a tape to store data sequentially. |
| Track |
Narrow concentric circle on the surface of a disk where data is magnetically stored. |
