Older PDAs typically used a combination of ROM (which cannot be edited) and RAM (which is volatile memory). If they lost all power, the user's files and programs would be wiped, and only the base software would be available. Newer PDAs and smartphones typically use Flash memory (which is non-volatile). If power is lost, these devices continue to hold user information.
