The level of data abstraction that describes exactly how the data is actually stored is the Physical level (also called the Internal level).

At the physical level, the database defines:

  • How data is laid out on disk or other storage devices.
  • Which file organizations, indexes (like B+ trees, hashing), and access methods are used.
  • Low‑level details such as blocks, memory allocation, and storage paths that are hidden from end users.

So if your options include something like:

  • Physical level / Internal level
    alongside Logical (Conceptual) and View (External) levels, the correct choice is Physical level.
