Asynchronous Programming

Created By vladimir

Processing multiple tasks while waiting for time consuming operations to finish.

Asynchronous programming allows a user to go about his business in an application while background processes run, improving the user experience.

Example:

  1. Initiate 3 file downloads. There is a big waiting time while the server sends all files.
  2. Only wait for the first download to finish instead of waiting for all 3
  3. When first download finishes, start processing it, then go on the next finished download and so on until all downloads are processed.
