What is telegraph?

A telegraph is like sending messages through wires, as if your thoughts could travel from one place to another without you having to shout or run.

Imagine you and your friend each have a special kind of flashlight, not the ones you use in the dark, but ones that can only send on or off signals. When you turn yours on, your friend’s turns on too, and when you turn yours off, theirs turns off too. This is like how a telegraph works, it uses wires to send simple messages by turning signals on and off.

A telegraph sends messages using short and long signals, like a code. These are called dots and dashes, and they can be used to spell out letters and words, just like how you use letters in your favorite storybooks!

When someone wants to send a message, they press a key that makes the signal go through the wire. The person on the other end hears the signals as beeps or clicks, and then translates them back into words.

It’s kind of like sending secret messages across town, but with wires instead of paper!
