2.1 The Structure of an RPM Package

Each RPM package consists of the following components:

• Header: Contains metadata about the package, such as its name, version, and dependencies.
• Payload: The actual files and directories that will be installed on the system.
• Scripts: Pre-installation and post-installation scripts that can configure the environment or perform specific tasks.

2.2 Benefits of Using RPM Packages

• Streamlined installation and removal processes.
• Automatic dependency resolution.
• Easy package verification and management.
