Question

how did the telephone diffrent the telegraph?

Answer 1

The telephone was later created around 1950 while telegraph was created around mid 1800. The key difference is that Morse code was used for telegraph while one had to speak on telephone

Answer 2

A telegraph only sends information to a person via different lengths of 'presses', and uses a morse code, which would be deciphered on the other end to make it a message.

A telephone allowed a person to speak directly to another through long distances without having to talk face to face.
