Semaphore vs Telegraph: What's the Difference?

What are the main differences between semaphore and telegraph communication?

Semaphore uses visual signals, like flags or lights, to convey messages, while the telegraph transmits electrical signals over wires.

Which method was faster for long-distance communication?

The telegraph was generally faster for long distances since it could transmit messages almost instantly compared to semaphore, which required line of sight.

Were there any limitations to using semaphore?

Yes, semaphore systems were limited by weather conditions and the need for a clear line of sight, making them less reliable in certain situations.

How did the invention of the telegraph impact communication?

The telegraph revolutionized communication by enabling near-instantaneous message delivery, which transformed business, journalism, and personal communication.

Can you give examples of semaphore systems used historically?

Certainly! The most famous semaphore system was the Chappe system in France, used during the late 18th and early 19th centuries.
