What does EOOW/LU bubble memory provide?

Explanation:
Bubble memory stores data in magnetic bubbles within a thin film, and those bubbles stay in place under magnetic fields even when power is removed. That retention without power is the defining trait, so it provides nonvolatile storage. It is a magnetic-based technology, which is why it isn’t optical storage, and it isn’t volatile like RAM, which loses data when power is cut. In EOOW/LU systems, having memory that retains information without continuous power is what makes this the appropriate description.
