This is the telegraph map vs submarine internet cable.

Idk much about telegraph so i've ask brave ai:

Telegraph: The telegraph uses electrical signals to transmit messages over wires, using Morse code encoding. It relies on manual switching and teleprinters for message transmission.

Internet: The internet uses digital signals to transmit data packets over a network of interconnected computers, using protocols like TCP/IP. It relies on automated switching and routing for message transmission.

In summary, the telegraph was a pioneering technology that laid the foundation for modern communication, but it was limited by its speed, distance, and message format. The internet, on the other hand, has revolutionized communication by providing fast, global, and interactive communication capabilities.
