Common Setup and Access Rights
Access Rights and Authority Levels are the rights or power granted to users to create, change, delete or view data and files within a system or network. These rights vary from user to user, and can range from anonymous login (Guest) privileges to Superuser (root) privileges. Guest and Superuser accounts are the two extremes, as individual access rights can be denied or granted to each user. Usually, only the system administrator (a.k.a. the Superuser) has the ability to grant or deny these rights.
Guest accounts, or anonymous logins, are set up so that multiple users can log in to the account at the same time without a password. Users are sometimes asked to type a username. This account has very limited access, and is often only allowed to access special public files. Usually, anonymous accounts have read access rights only for security purposes.
The superuser is an authority level assigned to system administrators on most computer operating systems. In Unix and related operating systems, this level is also called root, and has all access rights in the system, including changing ownership of files. In pre-Windows XP and NT systems (such as DOS and Windows 9x), all users are effectively superusers, and all users have all access rights. In Windows NT and related systems (such as Windows 2000 and XP), a superuser is known as the Administrator account. However, this Administrator account may or may not exist, depending on whether separation of privileges has been set up.

Famous quotes containing the words common, access and/or rights:
“In all conversation between two persons, tacit reference is made, as to a third party, to a common nature. That third party or common nature is not social; it is impersonal; is God.”
—Ralph Waldo Emerson (1803–1882)
“The nature of women’s oppression is unique: women are oppressed as women, regardless of class or race; some women have access to significant wealth, but that wealth does not signify power; women are to be found everywhere, but own or control no appreciable territory; women live with those who oppress them, sleep with them, have their children—we are tangled, hopelessly it seems, in the gut of the machinery and way of life which is ruinous to us.”
—Andrea Dworkin (b. 1946)
“His Majesty’s Government view with favour the establishment in Palestine of a national home for the Jewish people, and will use their best endeavours to facilitate the achievement of this object, it being clearly understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country.”
—A.J. (Arthur James)
