[Linux]What is linux ? Linus如是说

lincomet

To kind of explain what Linux is is you have to explain what an operating system is.
And the thing about operating system is, you, I mean you are never ever supposed to see it.
Because nobody really uses an operating system, people use programs on their computer,and the only mission in life of an operating system is to help those programs run.
So an operating system never dose anything on it's own.
It's only waiting for the programs to ask for certain resources or ask for some files on the disks or ask for the programs to connect them to the outside world.
And then the operating system comes, steps in and then tries to make it easy for people to write programs.

Linus说话也很经典了

hualala

试译如下：
为帮助解释什么是linux，你必须先解释什么是一个操作系统
而关于（解释）操作系统的麻烦是，我是说你永远不可能看到它
因为没有人真正使用一个操作系统，人们在他们的计算机上使用程序，而操作系统的唯一的任务就是帮助这些程序运行
所以操作系统本身从来没有主动地做任何事
它仅仅是等待应用程序请求某些资源或者请求硬盘上的某些文件或者请求程序把它们连接到外部
然后操作系统来了，干预并且试图让人们更容易的写程序。

觉得说得很对啊！

操作系统的动态资源调度与分配难道是被动的吗？应该说操作系统既是一个服务提供者又是一个监督者。它为程序的运行、用户的使用提供一个好的环境，并且要时刻维护这个环境。既有被动的地方又有主动的地方。

操作系统就是把电子硬件抽象，不要我们用户去处理电子信号。我们可以在统一的逻辑上用计算机。

楼上指的统一的逻辑是何解？

精典啊!

理想的操作系统是不是极为有效地管理运行于自身之上的程序，而自己几乎不消耗资源？按照Linus的说法。

linxu系统哪里有下呀！谢谢！
