操作系统"和命令外壳"之间有什么区别?

What is a difference between 'Operating System' and 'Command Shell'?

推荐答案

外壳和操作系统不同.让我解释一下.

A shell and an OS are different. Let me explain.

操作系统是由BIOS或EFI启动的程序.操作系统控制硬件的非常低级的方面，并为软件提供API以使用它们.操作系统通常是内核和大量应用程序的集合.操作系统示例包括Window $，Mac OS X，UNIX，Ubuntu，Solaris.请注意，Linux不是操作系统，而是内核，是操作系统中最重要的部分.

An operating system is a program initiated by either the BIOS or EFI. The OS controls the very low-level aspects of the hardware and provides APIs to software to use them. OSes are usually a collection of a kernel and a bunch of applications. Examples of OSes are Window$, Mac OS X, UNIX, Ubuntu, Solaris. Note that Linux is not an OS, but rather a kernel, which is the most important part of an OS.

外壳程序是在操作系统上运行并为操作系统提供用户界面的应用程序. shell的示例包括bash，sh，cmd.exe和windowserver.app.

A shell is an application that runs on the OS and provides the user interface to the OS. Examples of shells are bash, sh, cmd.exe and windowserver.app.

通常，操作系统随附一个或多个外壳.

Usually an OS comes packed with one or more shells.
