Quick Answer
Descriptors: implement __get__/__set__/__delete__ for attribute-level control - used for validation and computed properties. @property is the built-in descriptor shortcut. __slots__: replaces per-instance __dict__ with a fixed set of attributes, saves 40-50% memory per instance for classes with many instances. Properties add logic to attribute access without changing the public interface.
Answer
Descriptors control attribute access. Properties provide clean getters/setters. Slots reduce memory by avoiding __dict__. Useful for high-performance apps.
