Which architectural style is standardized and stateless, used for web application communication and integration?

• A. REST
• B. OAuth
• C. JSON
• D. on-premises network

Answer: (A)

REST is an architectural style built around standardized, stateless web communication. It guides how services are designed to interact over the web by focusing on resources identified by URLs, and using conventional HTTP methods like GET, POST, PUT, and DELETE to operate on those resources. The stateless aspect means the server does not retain any client context between requests; every request from a client must include all the information the server needs to process it, so each interaction stands alone. This combination—a standardized set of constraints, resource-based URLs, and stateless exchanges—makes REST highly interoperable and scalable for web application communication and integration. OAuth isn’t an architectural style for general web communication; it’s an authorization protocol often used with APIs to grant access. JSON is a data format used to represent information, not a communication architecture. An on-premises network describes where systems are deployed, not how they architect and standardize API interactions.
