Detailed explanation-1: -The two main types of primary storage are ROM, which is non-volatile, and RAM, which is volatile . Non-volatile memory keeps its contents even when the computer is switched off. Volatile memory loses its contents when power is lost.
Detailed explanation-2: -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. ROM is a more reliable form of storage, and it will often boot instructions and other mission-critical data.
Detailed explanation-3: -Primary memory usually refers to Random Access Memory (RAM), while secondary storage refers to devices such as hard disk drives, solid state drives, removable “USB” drives, CDs, and DVDs.
Detailed explanation-4: -Secondary memory consists of all permanent or persistent storage devices, such as read-only memory (ROM), flash drives, hard disk drives (HDD), magnetic tapes and other types of internal/external storage media.
