to expand on the Udo's answer, there is the program, "rpm", which manipulates specifically the packages it is asked to manipulate, and there is "yum", which is a more intelligent management system that can find dependencies and download .rpm files even if they're not in the system.
with the "rpm" command, you need to know the exact location of the .rpm package, but with "yum", you just need to know the name of it, and as long as it's available through your repositories list, it will be installed along with its dependencies

为了扩展 Udo 的答案，有一个程序“rpm”，它专门操作要求操作的包，还有“yum”，这是一个更智能的管理系统，可以查找依赖项并下载 .rpm 文件即使他们不在系统中。
使用“rpm”命令，您需要知道 .rpm 包的确切位置，但使用“yum”，您只需要知道它的名称，只要它可以通过您的存储库列表获得，它就会与其依赖项一起安装

Yum 是一个包管理器，rpms 是实际的包。
使用 yum，您可以添加或删除软件。该软件本身在 rpm 内。
包管理器允许您从托管存储库安装软件，它通常也会安装依赖项。
Yum is a package manager and rpms are the actual packages.
With yum you can add or remove software. The software itself comes within a rpm.
The package manager allows you to install the software from hosted repositories and it will usually install dependencies as well.
