REST, which stands for Representational State Transfer, is a widely used architectural style in web development that guides the design and interaction of networked applications. It’s a set of rules that allows different systems to communicate with each other over the web, typically using standard HTTP methods like GET, POST, PUT, and DELETE.
In a RESTful system, resources (like data or services) are identified by URLs, and clients can perform operations on these resources by making requests to these URLs. For example, when you want to view, update, or delete information, you send a specific type of HTTP request to the URL representing that resource.
REST is popular because it’s simple, scalable, and stateless, meaning each request from a client contains all the information the server needs to fulfill the request. This makes RESTful APIs (Application Programming Interfaces) easy to use, easy to scale, and highly compatible with a variety of web-based services.
