Answer 2

Answer:

While Samuel Morse’s invention of the telegraph in the 1830s and 1840s made it possible for the first time to communicate over long distances, the device had its drawbacks. An operator had to listen to incoming dots and dashes in Morse code, which slowed messages to a speed of 25 to 40 words per minute. A British system for automatically printing code in ink on paper only achieved 120 words tops.

Between 1870 and 1874, Edison developed a vastly superior system, in which a telegraph receiver utilized a metal stylus to mark chemically-treated paper, which then could be run through a typewriter-like device. It was capable of recording up to 1,000 words a minute, which made it possible to send long messages .if u like the ans please mark as brainliest plsplsplsplsplsplspls
