📦 Package Manager in Linux:

A package manager in Linux is like a digital librarian for your system. It helps you efficiently manage software by handling the installation, removal, and updating of programs. It's a crucial tool for maintaining a well-organized and smoothly running Linux system.

📁 Package:

A package is a bundled collection of files, scripts, and metadata that make up a software application or library. Think of it as a neatly wrapped box containing everything needed for a particular piece of software to work seamlessly on your system.
