软呢帽：
Fedora 是一个基于 Linux 内核的强大操作系统，可免费使用。它是一个受全球社区支持的开源分布式软件。最初，它被称为 Fedora Core。它于 2003 年推出。Fedora 推广了 Security-Enhanced Linux，该功能实现了大多数基于 Linux 的操作系统所缺少的多项安全策略。它本质上是健壮的和模块化的。 Fedora 借助快速的开发和发布周期在当前硬件平台上提供最新技术。
红色的帽子：
Red Hat Enterprise Linux 或 RHEL，是一种基于 Linux 的操作系统，专为企业设计。它是 Fedora 核心的继承者。它也是一个像 Fedora 和其他 Linux 操作系统一样的开源发行版。它比 Fedora 更稳定，但与 Fedora 相比不那么前沿。红帽通常通过包括技术支持和红帽网络在内的年度和月度订阅进行销售。它于 1994 年推出，主要为企业目的而开发。它在所有其他基于 Linux 的操作系统中更加稳定。
