Some more notes... It's been very late when writing this.

Of course the application has to take care of errors. If some errors 
survive the application has to cope. Some do not care at all, like video 
 and audio streams: If data is lost, no retransmission is tried. The 
human brain has to interpolate missing information and thus do the error 
correction.

Of course I meant "_No_ check for successful transmission is done."
