Detailed explanation-1: -The formal name for a chip that cannot be modified is mask ROM (from the manufacturing mask).
Detailed explanation-2: -Its static nature means it does not require refreshing. It is easy to test. ROM is more reliable than RAM since it is non-volatile in nature and cannot be altered or accidentally changed.
Detailed explanation-3: -Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware.
Detailed explanation-4: -Read-only memory (ROM) is the least flexible of all memory types because it contains an image that is permanently set at production time and cannot be reprogrammed. ROMs are used in high-volume devices that require no updates or corrections. Many devices also use a ROM to hold boot code.
