Detailed explanation-1: -Non-volatile random-access memory (NVRAM) is random-access memory that retains its information when power is turned off (nonvolatile).
Detailed explanation-2: -ROM (Read-Only Memory) is nonvolatile: data stored in ROM maintains integrity after loss of power. A computer Basic Input Output System (BIOS) firmware is stored in ROM. While ROM is “read only, ” some types of ROM may be written to via flashing, as we will see shortly in Section “Flash memory.”
Detailed explanation-3: -RAM. Unlike a computer’s RAM, the data in ROM is not lost when the computer power is turned off. While the ROM chip is commonly used in the startup operations for the computer, the RAM chip is often used in the recurrent tasks of the computer once the OS has been configured.
Detailed explanation-4: -ROM stands for Read Only Memory. The memory from which we can only read but cannot write on it. This type of memory is non-volatile. The information is stored permanently in such memories during manufacture.
