Detailed explanation-1: -Because ROM is read-only, it cannot be changed; it is permanent and non-volatile, meaning it also holds its memory even when power is removed. By contrast, random access memory (RAM) is volatile; it is lost when power is removed.
Detailed explanation-2: -Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device.
Detailed explanation-3: -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 the “Flash Memory” section.
Detailed explanation-4: -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.
