Paketinhallintatyökalu, also known as a package manager, is a software tool that automates the process of installing, upgrading, configuring, and removing software packages in a consistent manner. These tools are essential for managing the dependencies between different software components, ensuring that all required libraries and applications are present and compatible. By using a package manager, users can simplify the installation and maintenance of software on their operating system.

Package managers typically maintain a central repository of software packages, each containing the program files, metadata, and installation instructions. When a user requests to install a specific piece of software, the package manager retrieves the necessary files from the repository and installs them on the system. It also identifies and installs any other packages that the requested software depends on. This dependency resolution is a key feature, preventing conflicts and ensuring that all software functions correctly.

Common tasks performed by package managers include searching for available software, installing new applications, updating existing ones to their latest versions, and uninstalling software no longer needed. They also handle configuration updates and can sometimes manage system-wide settings related to the installed software. Examples of popular package managers include APT for Debian-based Linux distributions, YUM/DNF for Red Hat-based systems, Pacman for Arch Linux, and Homebrew for macOS. These tools significantly streamline software management, especially in complex environments with many installed applications and libraries.
