How do access levels work?

Access levels refer to the permissions granted to users or groups within a system or application, determining what actions they can perform and what data they can view. Typically, there are different levels, such as admin, user, and guest, each with varying degrees of access. Administrators usually have full control, including the ability to modify settings and user permissions, while regular users may have restricted access to certain features. This hierarchical structure helps maintain security and manage workflows effectively within organizations.
