What is a key difference between volatile and non-volatile memory?
Volatile memory is faster than non-volatile memory.
Volatile memory retains data without power, while non-volatile memory does not.
Non-volatile memory retains data without power, while volatile memory does not.
Volatile memory is more expensive.
Forklaring
Non-volatile memory such as ROM retains data even when power is removed. Volatile memory such as RAM does not.
