In what year did Guglielmo Marconi achieve wireless point-to-point telegraphy?

• A. 1894
• B. 1895
• C. 1906
• D. 1927

Answer: (A)

The concept tested is wireless point-to-point telegraphy—sending Morse-code style signals through the air from one place to another without any physical wire. Guglielmo Marconi achieved this in 1894, demonstrating a working wireless link between two points. This early breakthrough showed that signals could travel through the air and be received at a distance, proving the basic feasibility of wireless communication and laying the groundwork for all later advances. The later dates mark subsequent milestones in his career, but the first real demonstration of a wireless, point-to-point connection occurred in 1894.
