YUM (Yellowdog Updater, Modified) is a package manager used in Red Hat Enterprise Linux (RHEL) and other RPM-based Linux distributions. YUM is a command-line tool that helps users and system administrators to easily manage and install software packages on their systems.
Here are some key features of YUM:
1. Package Installation and Removal: YUM allows you to install, update, and remove software packages from the system. It resolves dependencies automatically, making it easier to manage software installations.
2. Repository Management: YUM uses repositories, which are collections of software packages hosted on servers. These repositories can be local or remote, and YUM helps users enable, disable, and manage these repositories efficiently.
3. Dependency Resolution: When installing or updating packages, YUM checks for and resolves dependencies automatically. It ensures that all required libraries and components are installed, avoiding conflicts and making package management more straightforward.
4. Update Management: YUM allows users to update all installed packages or specific packages to their latest versions available in the enabled repositories.
5. Plugin Support: YUM supports plugins that extend its functionality, allowing users to add new features or customisation options.
