Is flash memory a secondary storage device
Webstorage medium: In computers, a storage medium is any technology (including devices and materials) used to place, keep, and retrieve data . A medium is an element used in communicating a message; on a storage medium, the "messages" - in the form of data - are suspended for use when needed. The plural form of this term is storage media . ... WebSecondary memory is computer memory that is non-volatile, persistent and not immediately accessible by a computer or processor. It allows users to store data and information that can be retrieved, transmitted, and used by apps and services quickly and easily. Secondary storage is another name for secondary memory.

WebIn this regard, NAND flash is similar to other secondary data storage devices, such as hard disks and optical media, and is thus highly suitable for use in mass-storage devices, such as memory cards and solid-state … WebAug 23, 2024 · Secondary storage devices have at least two other advantages over RAM memory. Perhaps most importantly, disk, flash, and optical media are persistent , meaning that they are not erased from the media when the power is turned off. In contrast, RAM used for main memory is usually volatile —all information is lost with the power.
