synchronous vs asynchronous represents a topic that has garnered significant attention and interest. Asynchronous vs synchronous execution. What is the difference?. IMHO, these pictures do not all describe the synchronous vs asycnhronous execution of tasks For example, the second picture implies that asynchronous tasks require several threads. What is the difference between synchronous and asynchronous programming ....
To learn more, read about promises. Promises are another way in which the outcome of an asynchronous operation can be handled. The nice thing about promises is that the coding style feels more like synchronous code. Many libraries like node 'fs', provide both synchronous and asynchronous styles for some operations.
What is the difference between concurrency, parallelism and .... Asynchronous - Programming models. In sync, you write code as steps that are executed in order, from top to bottom.

In an async programming model, you write code as tasks, which are then executed concurrently. Executing concurrently means that all the tasks are likely executed at the same time. webserver - What is the difference between asynchronous and synchronous ....
Synchronous / Asynchronous communication has nothing to do with application waiting or not for resources. This perspective suggests that, synchronous communication is when communication looks like ping-pong one request and one response in that particular order. Another key aspect involves, asynchronous communication is when there could be multiple requests and responses could return in random order. Difference Between Synchronous and Asychnchronus I/O.

I have been learning the internals of an operating system and I am confused as to what the basic difference between synchronous and asynchronous I/O is. How does an operating system know whether it... Similarly, are async/await async or synchronous? This perspective suggests that, isn't this a synchronous behaviour, because things are getting executed in order as they should be?
This depends on how we define the terms synchronous and asynchronous. During my reading about Asynchronous Programming in .Net 4.5 async and await keywords I read Here the following paragraph Processing Asynchronous Requests In web applications that sees a large asynchronous and non-blocking calls? also between blocking and synchronous.

REST web services: synchronous or asynchrous? From another angle, what is the default behavior of REST web services - synchronous or asynchronous? If it's synchronous then can we create asynchronous?
Asynchronous: Asynchronous calls do not block (or wait) for the API call to return from the server.
