Early forms of telecommunications include smoke signals and drums. Drums were used in Africa, New Guinea, and South America, while smoke signals were used in North America and China. In the Middle Ages, the towers of the towers on the hills of the hill were used as a way to transmit the message. Such a transfer had the disadvantage that only one sign of information could have been expelled. One of the well-known examples of such notification was during the attack by the Spanish Army in England when a series of towers pulled a signal from Plymouth to London. Already in the 18th century, signals of traffic lights and heliographs were used as one kind of telecommunications. Today, the term telecommunication in the narrow sense implies data exchange with the use of electrical engineering, electronics, and other modern technologies.
