Explanation:
In Databricks, a "Managed Table" is one where both the underlying data files and the metadata (schema, properties) are managed by the Databricks platform. When you drop a managed table, the underlying data files are also deleted. By contrast, for external (unmanaged) tables, Databricks only manages the metadata, and dropping the table leaves the underlying files intact.
