🌍 What is Open Source?
🔹 Open Source vs. Closed Source
🔓 Open Source = Software whose source code is publicly available for anyone to view, modify, and distribute. Examples: Linux, React, Python, VLC Media Player.
🔒 Closed Source = Proprietary software where only the original developers can modify the code. Examples: Windows, macOS, Adobe Photoshop, Microsoft Office.

🔹 Famous Open-Source Projects
🚀 Linux – The OS powering 90% of cloud servers
📱 Android – The world's most popular mobile OS
🌐 Firefox & Chromium – Open-source web browsers
💻 React, Vue, Angular – Popular front-end frameworks
🛠 Node.js, Python, Rust, PHP – Powerful programming languages

🔍 How Open-Source Projects Work
Open-source software isn't created by a single company—it's built by a global community of developers who collaborate to improve the code.

1️⃣ The Code is Public
All open-source projects host their source code on platforms like GitHub, GitLab, or Bitbucket, where anyone can access it.

2️⃣ Developers Contribute Code
Anyone can suggest changes, fix bugs, or add new features by submitting a Pull Request (PR).

3️⃣ Maintainers Review & Merge Code
A team of maintainers (lead developers) review contributions and decide whether to approve or reject them.

4️⃣ Regular Updates & Improvements
With thousands of contributors, open-source software evolves rapidly, getting frequent updates, security fixes, and new features.

5️⃣ Licensing & Distribution
Open-source projects use licenses like MIT, GPL, and Apache, which define how the code can be used, modified, and shared.

💡 Why Open Source is Important?
✔️ Transparency & Security – Since the code is open, developers worldwide can audit it for security flaws.
✔️ Innovation & Collaboration – Open-source software allows people from all over the world to collaborate and innovate together.
✔️ Freedom & Customization – Unlike proprietary software, you can modify the code to fit your needs.
✔️ No Vendor Lock-In – You’re not dependent on a single company (unlike Microsoft, Apple, or Adobe products).
✔️ Used by Big Tech – Companies like Google, Facebook, Microsoft, and Tesla use open-source software in their products.

💰 How Do Open-Source Developers Make Money?

💰 Sponsorships & Donations – GitHub Sponsors, Open Collective, Patreon
💰 Bug Bounties & Grants – Companies pay for security fixes and improvements
💰 Freelancing & Consulting – Offering paid services based on open-source tools
💰 Selling Open-Source Services – Red Hat, MongoDB, and WordPress make billions with open-source software
💰 Building Premium Versions – Offering a free basic version with paid advanced features
