Clever idea. I suppose, is a UDP sowed my mail … No way. Since TCP guarantees delivery of data (if the signal does not reach to the sender, the connection is simply terminated), and its use for the delivery of important information on the Internet – namely, web-traffic, mail, FTP, SSH and the like. In all these cases, the loss the smallest piece of data plunges into disrepair everything else – if you download the 100 MB file, and 1 KB of data has lost its UDP, then the file is useless! Stop … if TCP really so wonderful, why need UDP? Then, sometimes loss of a piece of information is irrelevant. For example, VoIP.

If we speak on the phone via the Internet, and the relationship was broken only for a moment, TCP stall and require a repeat cues, until everything is up to you to denounce its best. UDP just jump over that moment and will continue to own transmission. When listening to the radio TCP may close the connection at all, that's all. UDP is much simpler and perfectly suited for cases where the continuity of the connection is more important accuracy of translation. Imagine what would happen to the online reporting on all meetings of the presidents, if used instead of TCP UDP! However, all these TCP / UDP, it seems, is no longer news. Why talk about them today? Because of BitTorrent. Now this system uses TCP, which means that there is a check security of data sent.
