In general, we know there are two types of memory in our computer- Hard Disk and Random Access Memory(RAM). In our daily conversation, we always refer the RAM as memory and Hard disk as Hard disk.
Theoretically, our computers indeed has two types of memory but there are classified as Volatile and Nonvolatile. When a computer's power is turned off, volatile memory loses its contents. As for Nonvolatile memory, by contrast, does not lose its content when the power is removed from the computer, for instance when the computer is turned off or in case of a power failure or other loses of electricity to the computer.
Another word, volatile memory is temporary whereas Nonvolatile memory is permanent.
Based on the explanation above, could you differentiate now whether RAM is volatile or nonvolatile? And let me ask you one more question, Hard Disk is volatile or nonvolatile? Check out the answer at the bottom of the post. Thank you.
