Detailed explanation-1: -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-2: -Secondary memory is not accessed directly by the Central Processing Unit(CPU). Instead, data accessed from a secondary memory is first loaded into Random Access Memory(RAM) and is then sent to the Processing Unit.
Detailed explanation-3: -Solid-state storage typically uses a variant of non-volatile memory known as NAND flash. SSDs have no moving parts, and they are capable of higher performance than mechanically addressed HDDs and tape, which use a head to read and write data to magnetic storage media.
Detailed explanation-4: -Secondary storage, sometimes called auxiliary storage, is non-volatile and is used to store data and programs for later retrieval. There are many kinds of secondary storage, each with advantages and disadvantages. Most storage devices use either magnetic or optical storage media.
