Here we have some descriptions for a few objects:
Computer— represents user's PC. It was built as a device that could be modified over time.Smartphone— represents the user's smartphone. This device is created as a complete object which couldn't be modified by the user.Watch— represents the user's watch. For this object, users can only replace a battery, but not all of its parts.Headphones— represents the user's headphones. This object was made easily replaceable, but not modifiable.
Based on object descriptions, classify their mutability. Consider the objects only within the framework of their description in this task, without comparing them with real equipment.
