What does REST stand for in API design?

• A. Reliable Event Services Transfer
• B. Representational State Transfer
• C. Real-Time Event State Transfer
• D. Resource Efficient State Transfer

Answer: (B)

Representational State Transfer is the correct definition of REST in the context of API design. The term describes a set of architectural principles for designing networked applications. When using REST, interactions between client and server must adhere to specific constraints, such as statelessness, resource identification through URIs, and the use of standard HTTP methods (e.g., GET, POST, PUT, DELETE). The idea of "representational state" refers to the fact that clients interact with resources (which are typically represented in a standardized format like JSON or XML) and that the state of the application is transferred from the server to the client through these representations. This focus on representations allows clients to manipulate resources via their representations rather than directly interacting with internal server states. This concept emphasizes how APIs can be structured around resources, enabling clearer and more intuitive communication across different systems while remaining scalable.
