A Web Service is a way for different applications (built in different languages or running on different systems) to communicate over the internet.
👉 Think of it like a messenger between two systems.
✅ Example
• A mobile app (Android) wants user data from a PHP server
• It sends a request → server responds with data
✔ This communication is called a Web Service
