During installation of Ubuntu, a single user and password is created. However, in order to keep your computer and documents safe, it is important to use a separate user account for each person that uses the computer. In this way, multiple users can have access to the computer while preserving and protecting their own personal settings and files.
|
|
|
|
|
在 Ubuntu 的安装过程中，会创建一个用户及其密码。然而，为了保持您的计算机和文档的安全，让每个使用该计算机的人使用各自的用户帐号很重要。这样，多个用户都能访问该计算机的同时，他们各自的个人设置和文件都得以保存和保护。

On Ubuntu, each user has their own <emphasis>home directory</emphasis> in which files and settings are stored. Furthermore, each user can be part of one or more <emphasis>groups</emphasis>, which define which parts of the system that user has access to.
|
|
|
|
|
在Ubuntu中，每个用户都有其自己的<emphasis>home目录</emphasis>来保存文件和设置。另外，每个用户可以加入一个或多个<emphasis>用户组</emphasis>，这定义了了用户可以访问系统的哪些部分。
