Sometimes you need to use these applications, so you may be able to temporarily get admin privileges to allow you to make the changes. If an application needs admin privileges, it will ask for your password. For example, if you want to install some new software, the software installer (package manager) will ask for your admin password so it can add the new application to the system. Once it has finished, your admin privileges will be taken away again.

有时您需要使用这些应用程序，因此您可临时获得管理特权，以允许您进行更改。如果应用程序需要管理员特权，它将向您询问密码。例如，如果您要安装某个新软件，则软件安装程序(软件包管理器)将向您询问管理员密码，以便它可将新的应用程序添加至该系统。一旦完成，您的管理员特权将再次被收回。

Admin privileges are associated with your user account. Some users are allowed to have admin privileges and some are not. Without admin privileges you will not be able to install software. Some user accounts (for example, the "root" account) have permanent admin privileges. You shouldn't use admin privileges all of the time, because you might accidentally change something you did not intend to (like delete a needed system file, for example).

管理员权限与用户帐户密切相关。您可以授予一些用户管理员权限，而对另一些用户禁用这项权限。没有管理员权限的帐户无法安装软件。一些用户帐户（例如“root”帐户）永久性拥有管理员权限。您不应该永远开启账户的管理员权限，以免误操作造成严重的后果（例如误删系统文件）。

In summary, admin privileges allow you to change important parts of your system when needed, but prevent you from doing it accidentally.

总之，管理员特权使您可在需要时更改系统的重要部分，但可防止您意外操作。

A user with admin privileges is sometimes called a <em>super user</em>. This is simply because that user has more privileges than normal users. You might see people discussing things like <cmd>su</cmd> and <cmd>sudo</cmd>; these are programs for temporarily giving you "super user" (admin) privileges.

拥有管理员特权的用户有时称为<em>超级用户</em>。这只是因为该用户比正常用户拥有更多特权。您可看到人们讨论如 <cmd>su</cmd> 和 <cmd>sudo</cmd> 这样的内容；这些是临时提供给您“超级用户”(管理)特权的程序。

Requiring users to have admin privileges before important system changes are made is useful because it helps to prevent your system from being broken, intentionally or unintentionally.

进行重要的系统更改前要求用户拥有管理员特权非常有用，因为它可防止您的系统被有意或无意地破坏。

If you had admin privileges all of the time, you might accidentally change an important file, or run an application which changes something important by mistake. Only getting admin privileges temporarily, when you need them, reduces the risk of these mistakes happening.

如果您始终拥有管理员特权，则您可能意外更改重要文件，或者错误运行更改重要内容的应用程序。仅在需要时临时获取管理员特权降低了这些错误发生的风险。

Only certain trusted users should be allowed to have admin privileges. This prevents other users from messing with the computer and doing things like uninstalling applications that you need, installing applications that you don't want, or changing important files. This is useful from a security standpoint.

您应当只为部分受信任的用户授予管理员权限。这样就可以阻止其它用户弄乱您的电脑，例如擅自卸载您需要的软件、擅自安装您不想看到的软件、或擅自改动重要的文件。从安全角度来说，只为完全信任的部分用户提供管理员权限是非常必要的。

You can only do some things, like installing applications, if you have admin privileges.

如果您拥有管理员特权，您仅能执行类似安装应用程序这样的操作。
