Given the nature of asynchronous programming, it is no surprise that the programming model can provide functionalities that complement the process of facilitating communication channels efficiently. Using the topic of HTTP communication as an example, the server can asynchronously handle multiple clients at the same time; while it is waiting for a specific client to make an HTTP request, it can switch to another client and process that client's request. Similarly, if a client needs to make HTTP requests to multiple servers, and has to wait for large responses from some servers, it can process the more lightweight responses, which have already been processed and were sent back to the client first. The following diagram shows an example of how servers and clients interact with each other asynchronously in HTTP requests:
