Detailed explanation-1: -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: -Nonvolatile memory is the memory that can keep the information even when it is powered off. In other words, nonvolatile memory requires power while storing the data; however, once the data is stored, the nonvolatile memory technologies do not require power to maintain the data stored.
Detailed explanation-3: -The digital computer Non-volatile memory is memory that retains its values even when power is removed. Earlier forms of non-volatile memory included various forms of read-only memory (ROM).
Detailed explanation-4: -Volatile memory, in contrast to non-volatile memory, is computer memory that requires power to maintain the stored information; it retains its contents while powered on but when the power is interrupted, the stored data is quickly lost.
Detailed explanation-5: -What Does Non-Volatile Memory (NVM) Mean? Non-volatile memory (NVM) is a type of computer memory that has the capability to hold saved data even if the power is turned off. Unlike volatile memory, NVM does not require its memory data to be periodically refreshed.
