Full origin of asynchronous →Frequently asked questions
What is the difference between synchronous and asynchronous learning?
Synchronous learning happens live, with everyone present at a set time, such as a scheduled video seminar. Asynchronous learning is delivered through recordings, readings and forums that students work through on their own schedule, with no fixed meeting.
What does asynchronous mean in programming?
It means a task is started and the program carries on with other work rather than waiting for the result. When the task finishes, the result is delivered back through a callback, promise or await, which keeps applications responsive during slow operations like network calls.
