What is Package Manager?

A tool that automates the process of installing, updating, configuring, and removing software packages.

Package managers handle software dependencies, versioning, and installation from repositories. Popular examples include APT (Debian/Ubuntu), DNF/YUM (Fedora/RHEL), Pacman (Arch Linux), and Zypper (openSUSE).

They maintain a database of installed packages and their dependencies, making it easy to keep systems updated and resolve conflicts.
