What is a characteristic of notebooks owned by a user?

Notebooks owned by a user are typically designed for private use and are primarily accessible only by the owner. This characteristic emphasizes the personal nature of these notebooks, allowing the owner to store sensitive information or thoughts without the risk of unauthorized access. This feature is important for privacy and secure management of data, as it ensures that only the owner has control over the contents. While collaboration features may exist that allow one to share notebooks selectively, by default, ownership is preserved, and access is restricted to the individual user. This is not the case for notebooks that are automatically shared or visible to all users, as these would contradict the notion of personal ownership. Notebooks that cannot be edited, on the other hand, imply read-only status, which is not a standard characteristic of user-owned notebooks.
