 | | Today, however, Morse is primarily remembered as the inventor of the electric telegraph and the related code system that bears his name. |
 | | The electric telegraph, as designed by Morse, was basically an electrical circuit consisting of a battery, a key, and an electromagnet, all connected by wire. |
 | | Morse code is an extremely reliable and clear form of communication and is still used by ham radio operators, many Third World countries, cargo ships, and others who cannot afford or do not wish to depend solely upon satellite equipment. |
