A Package Manager is a tool used in Linux and other operating systems to automate the process of installing, updating, configuring, and removing software packages. It manages dependencies, ensuring that all required components are installed and updated together, reducing the risk of conflicts or missing files. Package managers typically access centralized repositories where software packages are stored, allowing users to easily find and install applications. Examples of package managers include APT (used by Debian and Ubuntu), Yum or DNF (used by Fedora), and Pacman (used by Arch Linux). Package managers streamline software management, making it easier to maintain a system.
