The output of the command displays a list of packages that have updates available. It usually includes the package name, currently installed version, and the latest version available in the repository.

By running "yum check-update" periodically, you can see if any updates are available for your installed packages, allowing you to keep your system up-to-date with the latest software versions and security patches.
