Which of the following is an advantage of using REST APIs?

REST APIs offer several advantages, one of the key benefits being statelessness. This means that each request from a client to the server must contain all the information the server needs to fulfill that request. The server does not store any context or state information about the client, which simplifies server design and improves reliability.

By being stateless, REST APIs can scale more easily, as each request can be processed independently without the need for the server to retain information about previous requests. This architecture also enhances fault tolerance, as there is less dependency on the server's memory and it allows for more flexible deployment configurations.

Statelessness can also improve performance, especially in environments where numerous requests are made, as servers can process each request more quickly without needing to manage state information. Overall, the stateless nature of REST APIs contributes to their popularity in network programmability and web service design.
