Linux是由Linus Torvalds开发的一组类似于Unix的开源操作系统。它是Linux发行版的打包。一些最常用的Linux发行版是Debian，Fedora和Ubuntu。它基本上是用C语言和汇编语言编写的。 Linux中使用的内核是Monolithic内核。 Linux发行版的目标系统是云计算，嵌入式系统，移动设备，个人计算机，服务器，大型计算机和超级计算机。 1991年发布了第一个Linux版本。
2. macOS：
macOS是Apple Incorporation提供的一系列专有图形操作系统。它以前被称为Mac OS X，后来被称为OSX。它是专门为Apple mac计算机设计的。它基于Unix操作系统。它是使用C，C++，Objective-C，汇编语言和Swift开发的。它是仅次于Windows的个人计算机中第二使用最多的操作系统。苹果于2001年发布了macOS的第一个版本。
