There is a high level of software detection called data error analysis. Basically, there is no way for a computer to know if the data sent was received without and infinite loops of checks and confirms that would slow computing to a halt.

For networks, this means that systems are designed to have data sent in scattered arrays that will verify if that signal was interfeared with, wait, and then send again if priority is low.

3 things send data at the same time, priority 1,2,3 respectively, one send first and 2 and 3 wait. So on and so on.
