1. What is the difference in volatile and nonvolatile memory?
nonvolatile memory
Two common types of BIOS ROM are the EPROM (Erasable Programmable Read-Only Memory) and Flash memory. EPROM can be erased using UV light and reprogrammed, while Flash memory can be electrically erased and rewritten, allowing for easier updates. Modern systems typically use Flash memory due to its flexibility and convenience.
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.
it is nonvolatile & highly reliable
nonvolatile storage
ROM is involatile because its name means Read Only Memory, hinting that the data stored on it cannot be altered. The word involatile means long term and not changeable.
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.
