What is the difference between Listening and Hearing??????

You asked the question and also answered it. You have given a good answer so I do not have anything to say.

Listening is simply hearing the communication and letting it go in one ear and out the other. Hearing is letting the information enter your head processing it and understanding it or asking for feedback to make sure you understood it correctly in the first place.

YEah, i do agree with what u say here.. HEaring is the process of receiving information from sources, while listening is the processing of information received.. haha =D BUt then, in terms of usage of the two words, both can be used with the same meaning, such as, "Are u listening"?? or, "Do u hear me"?? hehe
