Use of rpm and yum in Fedora

In Fedora, rpm is mainly used to operate a separate rpm software package. If you use rpm to install the software, you must manually solve the dependency of the software package, which is quite troublesome. Yum is much better. As long as the software library contains this software, a command will solve the problem, and yum will solve the dependency problem of the software package on its own. I. rpm usage // 1.
