COMPUTER FUNDAMENTALS

Detailed explanation-1: -The term backing storage refers to any non-volatile data storage that will retain a computer’s data even after the computer is powered off. Common types of backing storage devices are hard drives, SSD, external hard disk drives, optical media such as CD or DVD, and flash media such as thumb drives and memory sticks.

Detailed explanation-2: -Hard disks are nonvolatile storage devices that are used to store and retrieve data quickly. Nonvolatile storage is physical media that retains data without electrical power. This means that no data is lost when the computer is powered off, making hard disks suitable for permanent storage of information.

Detailed explanation-3: -Since ROM is permanent memory, it is referred to as non-volatile memory. Because the data in read-only memory (ROM) is not lost when a computer is shut down and restarted, it is not volatile.

Detailed explanation-4: -A backup storage device is used to make copies of data that is actively in use. Backup machines provide redundancy of data residing on primary storage. Should the storage medium, such as a hard disk drive (HDD), fail or become corrupted, the original data is recovered from copies on the backup hardware.
