Explain what the abbreviation REST means and how it is used in web development

REST (Representational State Transfer) is an architectural style for building distributed systems, particularly web services. It defines a set of principles and constraints that make interaction between clients and servers simple, scalable, and efficient.

Main ideas of REST:

• Use of standard HTTP methods (GET, POST, PUT, DELETE) for resource operations.
• Resources are identified by unique URIs.
• No server-side state between requests (stateless).
• Use of resource representations (e.g., JSON or XML).

In web development, REST is widely used for creating APIs that allow clients (web applications, mobile apps) to interact with servers through understandable and standardized requests.

Example of a REST request to get user information:

GET /users/123 HTTP/1.1
Host: example.com

The server's response can be in JSON format with user data.

Thus, REST simplifies the development and integration of services, making them more flexible and compatible.
