I have seen a very peculiar situation. I have noticed that at some point during connected to the Internet, my Internet Browser stops working and just displays a "Sending Request". However, my Messenger stays active.
I would like to know how can Messenger stay active and the Internet Browser stops working.
Does each application run on different ports or layers?
Please note: this question is only to know how does these application access the Internet or how each application connects outside my office. I am not looking to solve any problem, just get orientation on the"how-to" of each communication of the each apps.
