Hi Mahender,

Usually, asynchronous call is referred as invoking a method on another thread without blocking current working thread. You'll see it being used in calling WebService, I/O operations, etc. In AJAX, it's usually implemented with request for a resource via XmlHttpRequest, it's the essential of AJAX.

Callback is executable code that is passed as an argument to other code, or we can call itMethod Pointer. It enables the other code to call the executable code via the pointer.

Hope this helps.
