The telegraph had several disadvantages, including its reliance on extensive infrastructure, such as wires and stations, which could be costly and difficult to maintain. Additionally, it required skilled operators to send and receive messages, limiting accessibility. The technology also had limitations in terms of distance and speed, as messages could be delayed by technical issues or outages. Finally, the telegraph's inability to convey tone or context often led to misunderstandings in communication.
The advantage over telegraph is that ordinary people could read the output and over the telephone that there was a written record and the recipient did not need to be present to receive a message. The disadvantages are that it is expensive and requires special phone connections.
