Which of the following best describes an asynchronous RPC call?

An asynchronous RPC (Remote Procedure Call) enables a process to initiate a request and then continue executing without waiting for the response from the remote service. This means that the system can handle other tasks or processes while it waits for a response, which is particularly beneficial in environments where high throughput and responsiveness are required.

In contrast, synchronous RPC calls would block the execution of subsequent tasks until the response is received, which can lead to inefficiencies in certain scenarios, especially when network latency or server response times are variable.

The characteristic of allowing other processes to run concurrently while waiting for a response is key to understanding how asynchronous operations facilitate smoother and more efficient workflows. This enables systems to be more responsive and better utilize resources, ultimately leading to improved performance in multitasking environments.
