Understanding Open Source

Before diving into the world of open-source contributions, it’s essential to understand what open source means and how it works. Open-source software is code that is publicly available for anyone to view, use, modify, and distribute. This collaborative approach to software development has led to the creation of many popular projects, including the Linux operating system, the Apache web server, and countless programming languages and frameworks.

Open-source projects are typically hosted on platforms like GitHub, GitLab, or Bitbucket, which provide version control and collaboration features. These platforms allow developers from around the world to work together on projects, share ideas, and contribute code.
