Final answer:
In Windows, a user is authorized to perform certain actions like logging on or performing a backup by a right, which is assigned to user accounts.
Step-by-step explanation:
The actions a user can perform in Windows, such as logging on or performing a backup, are authorized by a right. Unlike permissions, which are applied to objects like files and folders, rights are assigned to user accounts and dictate what activities users can carry out on a computer system. For example, the right to log on to a system allows a user to gain access to the computer, while the right to perform a backup enables them to use backup tools to save copies of data.
