From
On March 10, 1876, Alexander Graham Bell spoke into his device and said to his assistant, “Mr. Watson, come here, I want to see you.” In doing so, Bell launched the telephone era with the first bi-directional electronic transmission of the spoken word. At least that is how the story typically goes. While Bell received the first patent for a telephone, the origin of the telephone is complicated and inconclusive, with Elisha Gray, Antonio Meucci of Italy, and Innocenzo Manzetti each claiming to be the phone’s true inventor.

Students should conduct an image search to see what early telephones looked like. (For example, the images found here: They should describe what they see: “a wooden box”, “two metal circles”, “a mouthpiece”, etc… and how early telephones are different from the phones they use today in terms of material and form.

From
The telegraph and telephone are both wire-based electrical systems, and Alexander Graham Bell's success with the telephone came as a direct result of his attempts to improve the telegraph. When Bell began experimenting with electrical signals, the telegraph had been an established means of communication for some 30 years.

(Possible queries: “invention of the telephone, telegraph”, “telephone, improvements to telegraph”).
From
Although a highly successful system, the telegraph, with its dot-and-dash Morse code, was basically limited to receiving and sending one message at a time. Bell's extensive knowledge of the nature of sound and his understanding of music enabled him to conjecture the possibility of transmitting multiple messages over the same wire at the same time. Although the idea of a multiple telegraph had been in existence for some time, Bell offered his own musical or harmonic approach as a possible practical solution. His "harmonic telegraph" was based on the principle that several notes could be sent simultaneously along the same wire if the notes or signals differed in pitch.

(Possible queries: “difference between telegraph and telephone”, “telegraph and telephone, how they work”).
From
Telegraphs generally required skilled operators who knew Morse code, and so most people never had telegraph machines in their homes; to send a telegram, one would go to a local telegraph office. The telephone, on the other hand, required no special skill; you only needed to speak into the microphone, and listen through the earpiece. In time, sophisticated switching networks were developed that allowed telephone users to dial each other directly. Similar technology was used for telegraphy (telex) until quite recently.
It is interesting to note that the earlier invention, the telegraph, was actually a digital device in the sense that the data it transmitted consisted of simple on-off patterns, and its output was a string of fixed symbols. Now, of course, cellular telephones are used to send text messages as well as voice; telephones and telegraphs are again united.
