RAM is non permanent. When the computer is turned off, everything on the RAM is deleted. It is only used temporarily for applications/programs that want to retrieve data quickly.
Non-volatile memory technology does NOT get deleted when you turn the computer/laptop off. It stays there. A common object that does this is the hard disk drive. You can store documents/data on this without fear of losing it.
1. What is the difference in volatile and nonvolatile memory?
nonvolatile memory
Non-volatile. It retains its memory even if power is removed.
Volatile memory loses its stored data when power is lost, while nonvolatile memory retains its stored data even without power. Examples of volatile memory include RAM, while nonvolatile memory includes hard drives and SSDs.
Flash memory consists of nonvolatile memory chips that can be used for storage by the computer or the user. Flash memory was introduced in 1984.
A hard drive is static or nonvolatile memory.
flash
it is nonvolatile & highly reliable
nonvolatile storage
Nonvolatile memory retains data even when power is cut off, like in ROM chips. Nonvolatile storage devices can be slower than volatile ones as they often use technologies such as flash memory. This type of memory is commonly used in devices like USB drives and solid-state drives.
PROM stands for programable Read only memory. it is a nonvolatile memory.
