Installing, removing, and updating packages is a typical activity on Linux. Most of the Linux distributions provides some kind of package manager utility. For example, apt-get, dpkg, rpm, yum, etc.
On some Linux distributions, yum is the default package manager.
Yum stands for Yellowdog Updater Modified.
