1. Linux：
Linux 是一组开源的类 Unix 操作系统，由 Linus Torvalds 开发。它是一个打包的 Linux 发行版。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。 Linux 的第一个版本于 1991 年推出。用于个人计算机的 Linux 的最新版本是 5.6(内核)。
2. GhostBSD :
GhostBSD 是由 Eric Turgeon 和 GhostBSD 团队开发的免费开源操作系统。它是一个类 Unix 操作系统，其设计灵感来自 TrueOS 操作系统。它有一个名为 MATE 的默认桌面环境。它专门用于台式机和工作站。早些时候，它使用了一个名为 GNOME 的默认桌面环境。 GhostBSD 的第一个版本于 2009 年推出。 GhostBSD 的最新稳定版本是 19.10。它具有带有模块的单片内核。
