相关介绍：Linux
Linux是一种自由和开放源代码的类UNIX操作系统。该操作系统的内核由林纳斯·托瓦兹在1991年10月5日首次发布。
Linux拥有以下特性：类似于Unix的基本思想，支持完全免费与自由传播，完全兼容POSIX1.0标准，支持多用户、多任务、有着良好的界面、支持多种平台。Linux 能运行主要的UNIX工具软件、应用程序和网络协议。它支持32位和64位硬件。Linux继承了Unix以网络为核心的设计思想，是一个性能稳定的多用户网络操作系统。
严格来讲，Linux这个词本身只表示Linux内核，但人们已经习惯了用Linux来形容整个基于Linux内核，并且使用GNU 工程各种工具和数据库的操作系统。
Linux有着许多不同的版本，但它们都使用了Linux内核。Linux可安装在各种计算机硬件设备中，比如手机、平板电脑、路由器、视频游戏控制台、台式计算机、大型机和超级计算机。
