What is a characteristic of using asynchronous APIs?

With asynchronous APIs, the client does not wait for an immediate response; it typically receives an acknowledgment and continues processing, handling the actual response when it eventually arrives via a callback or polling mechanism.

While asynchronous operations can contribute to overall system efficiency, network throughput is primarily determined by network bandwidth and latency, not solely by the asynchronous nature of the API call itself.

Asynchronous APIs improve application scalability because they allow the client to submit a request and then perform other operations without waiting for the response. This non-blocking behavior means the client can handle multiple requests concurrently or perform other work, preventing bottlenecks and allowing the application to manage more tasks efficiently.

The client absolutely receives a response with asynchronous APIs, but it typically receives it later, out of band, or through a callback mechanism, rather than waiting synchronously for it.
