Detailed explanation-1: -ROM. Unlike RAM, Read Only Memory (ROM) delivers both non-volatile and permanent primary storage. ROM retains its contents even if the device loses power. You cannot change the data on it, you can only read it.
Detailed explanation-2: -Non-volatile memory is a permanent memory. A system does not lose the data and information stored within the memory even after a user shuts down the system or interrupts the power supply. This type of memory is not very economical, and it takes time to fetch and store data. But it can store higher volumes of data.
Detailed explanation-3: -Secondary storage, sometimes called auxiliary storage, is non-volatile and is used to store data and programs for later retrieval. There are many kinds of secondary storage, each with advantages and disadvantages. Most storage devices use either magnetic or optical storage media.
Detailed explanation-4: -Permanent storage, also called persistent storage, is any computer data storage device that retains its data when the device is unpowered. A common example of permanent storage is the computer’s hard drive or SSD.
