What is RESTful webservices?

RESTful web services are a software architectural style that uses standard HTTP methods (GET, POST, PUT, DELETE, etc.) to create, read, update, and delete resources. They emphasize a stateless client-server communication, where each request from the client to the server must contain all of the information needed to understand and process the request. They are commonly used for building APIs that allow different applications to communicate with each other over the internet.
