- webserver - What is the difference between asynchronous and synchronous . . .
Synchronous 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
- Using resolved promise data synchronously - Stack Overflow
20 I want to know if there is any way at all to use the data from a resolved promise in 'normal' synchronous code There isn't a way to write completely synchronous code when handling asynchronous responses Once any operation is asynchronous, you have to deal with the response using asynchronous techniques and cannot program with it synchronously
- Asynchronous vs synchronous execution. What is the difference?
SYNCHRONOUS EXAMPLE: Any process consisting of multiple tasks where the tasks must be executed in sequence, but one must be executed on another machine (Fetch and or update data, get a stock quote from financial service, etc ) If it's on a separate machine it is on a separate thread, whether synchronous or asynchronous
- Is there any reason to use a synchronous XMLHttpRequest?
Synchronous calls block the browser which leads to a terrible user experience Thus my question I couldn't think of any good reason to use it
- Synchronous delay in code execution - Stack Overflow
It is impossible to make a synchronous delay in javascript, simply because JavaScript is a single-threaded language The browser (most common JS runtime environment) has what's called the event loop So everything that the browser does happens in this very loop And when you execute a script in the browser, what happens is:
- What is the difference between Asynchronous calls and Callbacks
The problem with synchronous callbacks is they can appear to "hang" The problem with asynchronous callbacks is you can lose control of "ordering" - you can't necessarily guarantee that "A" will occur before "B" Common examples of callbacks include: a) a button press handler (each different "button" will have a different "response")
- When to use Task. Delay, when to use Thread. Sleep?
Use Thread Sleep when you want to block the current thread Use await Task Delay when you want a logical delay without blocking the current thread Efficiency should not be a paramount concern with these methods Their primary real-world use is as retry timers for I O operations, which are on the order of seconds rather than milliseconds
- c# - Calling async method synchronously - Stack Overflow
public async Task<string> GenerateCodeAsync() { string code = await GenerateCodeService GenerateCodeAsync(); return code; } I need to call this method synchronously, from another synchronous method How can I do this?
