I understand how like morse code “works” sending the message across long distances. But how could the sender know how to get the message to their right destination? And once it got there, how did the receiving party decode the message? In movies the receiver is always just tapping the telegraph device and is like “sir we have a message from the front lines!!” but how does it work??
In: Technology
They started out point-to-point. You would send a message down a line. The person at the end of the line would relay the message down another line and so forth, until it reached the appropriate destination.
