What are web services?

Web services are like messengers that help different computers talk to each other.

Imagine you have a toy phone, and your friend has another toy phone. When you call them, you can share messages or even play games together, even though the phones are different. Web services work in a similar way, they let computers send information back and forth, no matter where they are.

Think of web services like a postal service. If you write a letter and put it in the mailbox, the postal worker takes it to your friend’s house. In the same way, when one computer wants to share something with another, it sends a message through a web service, which then delivers it to the other computer.

Web services are used all around, like when you order food from an app, or when your video game talks to the internet to give you new levels. It's like having invisible helpers that make everything work smoothly without you needing to know all the details behind the scenes.
