The concepts:
Sending the Signal:
Network data in the form of electronic signals is sent to all the computers on the network. The computer whose address matches the address encoded in the original signal will accepts the data and all other computers reject the data.
Signal Bounce:
Electronic signal moves from one end of the cable to the other.
The signal will keep bouncing back and forth along the cable as long as it didn’t get interrupted and will prevent other computers from sending signals.
So the signal must be stopped after it reaches the proper destination address.
