The EOOW/LU bubble memory provides which type of storage?

• A. Volatile storage
• B. Magnetic storage
• C. Nonvolatile storage
• D. Optical storage

Answer: (C)

Bubble memory stores information as magnetic bubbles in a thin film, and those bubbles stay in place even when power is removed. That means the data is retained without power, which is the hallmark of nonvolatile storage. It’s not dependent on continuous power to keep the information, unlike volatile storage such as RAM. It’s also not optical storage. So the best answer is nonvolatile storage.
