INTRODUCTION:
- It is used to install, remove and update RPM Packages.
- The best part is this, It automatically install dependency packages (if any).
For Example:
If you are installing a package abc.rpm and x.rpm, y.rpm, z.rpm must be installed before installing abc.rpm, Then x.rpm, y.rpm, z.rpm is called dependency packages of abc.rpm.
While Installing abc.rpm, YUM will automatically install x.rpm, y.rpm, z.rpm.
