Is the message the same as the telegram?

Message: refers to the collection of text, data or commands transmitted through communication network or other means, which can contain various types of information, such as e-mail, short messages, instant messages, etc. Information is usually transmitted electronically and can be processed and stored on computers or other electronic devices.

Telegraph is an early telecommunication communication method, which transmits information through the transmission of electrical signals. Telegrams usually use Morse code or other coding methods to convert text information into electrical signals, and then transmit them through telecommunication lines. Telegraph used to be the main way of long-distance communication, but with the development of telephone and internet, it has been gradually eliminated.
