Detailed explanation-1: -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-2: -ROM is more reliable than RAM since it is non-volatile in nature and cannot be altered or accidentally changed.
Detailed explanation-3: -You can’t change your ROM data just by doing ordinary computer activities. In fact, you can’t actually directly access data stored in the ROM. If you need data from the ROM, you must first transfer it to the RAM, where your processor can then access it.
Detailed explanation-4: -PROM or programmable ROM (programmable read-only memory) is a computer memory chip that can be programmed once after it is created. Once the PROM is programmed, the information written is permanent and cannot be erased or deleted.
