YUM allows you to install predefined groups of packages, such as development tools or web servers, by specifying the group name. This can simplify the installation of multiple related packages.
sudo yum groupinstall group-name
Example:

YUM can remove dependencies that are no longer needed by any installed package. This helps to keep your system clean and efficient by removing unnecessary files.
