Explanation:
* synchronous: Code execution must wait for an API call to return before continuing.
* asynchronous: Code execution does not need to wait for an API call to return before continuing.
* REST: Data is called indirectly using generic HTTP methods such as GET, POST, PUT, and DELETE.
* RPC: Calls to request a service from a remote server must execute the same way as a request to the local system.
Comprehensive Detailed Step by Step Explanation with References
* Synchronous:
* Explanation: In a synchronous API call, the client must wait for the server to process the request and return a response before it can proceed with further execution.
* Mapping: "Code execution must wait for an API call to return before continuing."
* Asynchronous:
* Explanation: In an asynchronous API call, the client can continue processing other tasks while waiting for the server to respond. This improves the efficiency and responsiveness of the application.
* Mapping: "Code execution does not need to wait for an API call to return before continuing."
* REST (Representational State Transfer):
* Explanation: REST is an architectural style for designing networked applications. It relies on a stateless, client-server communication protocol, typically HTTP. RESTful APIs use standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources.
* Mapping: "Data is called indirectly using generic HTTP methods such as GET, POST, PUT, and DELETE."
* RPC (Remote Procedure Call):
* Explanation: RPC is a protocol that one program can use to request a service from a program located on another computer in a network. The calls are made in the same way as a local function call.

* General programming resources on synchronous vs. asynchronous API calls Therefore, the correct mapping is:
* synchronous "Code execution must wait for an API call to return before continuing."
* asynchronous "Code execution does not need to wait for an API call to return before continuing."
