In this case, the asynchronous call doesn't involve multithread programming or handling concurrency at the OS level.周六, 04 4月 2026 03:13:00 GMThttps://stackoverflow.com/questions/4228387/what-does-it-mean-when-a-web-service-is-asynchronous79 I know this is an old topic, but whether a web service is synchronous or asynchronous depends on the design of the web service and has nothing to do with Ajax. An asynchronous web service transaction proceeds like this: The client calls the web service. In the call the client sends a callback end point implemented as a service by the client.周日, 05 4月 2026 02:22:00 GMThttps://stackoverflow.com/questions/16715380/what-is-the-difference-between-asynchronous-and-synchronous-http-requestSynchronous / Asynchronous communication has nothing to do with application waiting or not for resources. Synchronous communication is when communication looks like ping-pong one request and one response in that particular order. Asynchronous communication is when there could be multiple requests and responses could return in random order.周四, 02 4月 2026 02:04:00 GMThttps://stackoverflow.com/questions/16336367/what-is-the-difference-between-synchronous-and-asynchronous-programming-in-nodeWhen an asynchronous operation (like the second database query) is seen, the code is parsed and the operation is put in the queue, but in this case a callback is registered to be run when this operation completes. The queue may have many operations in it already. The operation at the front of the queue is processed and removed from the queue.周四, 02 4月 2026 07:47:00 GMThttps://stackoverflow.com/questions/33538892/what-really-is-asynchronous-computingAsynchronous is a general term, which does not have widely accepted meaning. Different domains have different meanings to it. For instance, async IO means that instead of blocking on IO call, something else happens. Something else can be really different things, but it usually involves some sort of notification of call completion. Details might differ. For instance, a notification might be ...周四, 02 4月 2026 08:59:00 GMThttps://stackoverflow.com/questions/600795/asynchronous-vs-multithreading-is-there-a-difference8 Asynchronous calls don't even need to occur on the same system/device as the one invoking the call. So if the question is, does an asynchronous call require a thread in the current process, the answer is no. However, there must be a thread of execution somewhere processing the asynchronous request. Thread of execution is a vague term.周五, 03 4月 2026 17:26:00 GMThttps://stackoverflow.com/questions/9343594/how-to-call-asynchronous-method-from-synchronous-method-in-c17 You can call any asynchronous method from synchronous code, that is, until you need to await on them, in which case they have to be marked as async too.周三, 25 3月 2026 08:47:00 GMThttps://stackoverflow.com/questions/4844637/what-is-the-difference-between-concurrency-parallelism-and-asynchronous-methodsConcurrency is having two tasks run in parallel on separate threads.
