What Is APT And How Does It Work?
APT, which stands for Advanced Package Tool, is a package management system used primarily on Debian-based Linux distributions, such as Ubuntu. It simplifies the process of managing software installations, updates, and removals. APT works with package repositories, which are collections of software packages that are stored on servers. When you use an APT command, it queries these repositories to find and install the required software.
APT provides a high-level interface for handling .deb packages, making it easier for users to manage software. With commands like apt-get, apt-cache, or the newer apt, users can easily install, upgrade, or remove software. It also handles dependencies automatically, ensuring that all necessary supporting packages are installed alongside the main software, thus streamlining the user experience.
What Is YUM And How Does It Function?
YUM, short for Yellowdog Updater, Modified, is a package management tool for RPM-based Linux distributions, such as CentOS and Fedora. Like APT, YUM facilitates the process of installing, updating, and removing software packages by connecting to online repositories where these packages are stored. This allows users to manage their software in a more efficient manner without needing to manually resolve dependencies.
YUM uses a command-line interface to perform various operations, with the yum command being the primary method for management tasks. It automatically resolves package dependencies and updates packages to the latest versions available in the repositories. YUM also supports plugins, which can extend its functionality, making it a versatile tool for system administrators.
What Are The Main Differences Between APT And YUM?
The primary difference between APT and YUM lies in the Linux distributions they are associated with; APT is used by Debian-based systems while YUM is used by RPM-based systems. Additionally, they have different underlying package formats — APT manages .deb files, whereas YUM deals with .rpm files. This difference is intrinsic to the design and functionality of each tool and affects how they handle package management.
Another key distinction is in their command syntax and user interface. While both tools aim to provide similar functionalities, their commands differ.
