Explanation

DAC is a type of access control that allows the owner of an object to define who has access to it. Permissions are applied on a user and group level. For example, the owner of a file can grant read, write, and execute permissions to the users and groups they choose. RBAC is a type of access control that defines permissions based on a user's role. Roles are assigned to users based on their job function or responsibilities. For example, a user with the role of "employee" might have read-only access to all files, while a user with the role of "manager" might have read, write, and execute permissions to all files.
