What is the idea behind asynchronous programming?
Asynchronous programming is a model of programming that focuses on coordinating different tasks in an application with the goal that the application will use the least amount of time to finish executing those tasks. An asynchronous program switches from one task to another when it is appropriate to create overlap between the waiting and processing time, and therefore shorten the total time taken to finish the whole program.
How is asynchronous programming different from synchronous programming?
In synchronous programming, the instructions of a program are executed sequentially: a task has to finished executing before the next task in the program starts processing. With asynchronous programming, if the current task takes a significant amount of time to finish, you have the option to specify at one time during the task...
