user mode

基本解释

It is safe, since -- as the name "single-user mode" suggests -- only the superuser is able to access the system.
这样是安全的——就像它的名字“单一用户模式”的含意一样——只有超级用户可以访问系统。
Multi-user mode enables the workbench code to be shared by all users on a given machine, saving you both time and disk space.
多用户模式允许所有用户在一台给定的机器上共享这个工作台代码，从而节约您的时间和磁盘空间。
You might also use it if you need to boot a system into single-user mode or perhaps runlevel 3 instead of your normal runlevel.
如果需要将系统引导为单用户模式，或者要让运行级别为 3 而不是普通的运行级别，也可能会使用到它。

Aside from 'Standard' mode, the user can also select from 'Cinema' for authentic movie theater-like acoustics, 'Game' for reproducing a clear sense of direction, which can be vital for game-playing, and 'Music' for those times when the viewer simply wants to enjoy the original sound, such as might be heard in a recording studio.

Based on that illustration up there, we're going to hazard a guess it could be used in Apple's MacBook and iMac lines, though the patent application doesn't explicitly exclude mobile devices, either.
