Explanation: 

Detailed explanation-1: -Secondary storage is needed to keep programs and data long term. Secondary storage is non-volatile, long-term storage. Without secondary storage all programs and data would be lost the moment the computer is switched off.

Detailed explanation-2: -Magnetic disk drives are one of the most widely used types of secondary storage. The hard disk drive (HDD), the most common form of magnetic disk storage, uses a magnetic process to read, and write data. Data is stored as tracks divided into sectors that contain blocks of data.

Detailed explanation-3: -Secondary storage is necessary because memory, or primary storage, loses its data when a computer is turned off whereas secondary storage does not. Therefore, it is commonly known as non-volatile storage. The data on it stays there until it is deleted or overwritten by the user.

Detailed explanation-4: -Secondary storage is required to store programs and data over an extended period. Secondary storage is non-volatile, long-term storage. When a computer is shut off without additional storage, all apps and data are lost.

Detailed explanation-5: -The primary memory is costly and volatile in nature moreover, space is also limited. Hence, we use secondary memory when we need to store the data permanently at a cheaper cost. These devices store a large amount of data like audios, videos, text files, images, etc.
