Review Questions

• How did the invention of the telegraph change communication practices in society during its time?
  • The invention of the telegraph dramatically transformed communication practices by enabling messages to be sent instantaneously over long distances. Prior to its development, communication relied on slower methods such as postal services or messenger systems. With the telegraph, information could be transmitted in real-time, which not only improved personal correspondence but also enhanced business operations, journalism, and governmental functions.
• In what ways did Morse Code enhance the efficiency of telegraphic communication?
  • Morse Code enhanced the efficiency of telegraphic communication by providing a standardized method for encoding messages into short signals. This coding system made it easier for operators to send and receive messages quickly over telegraph lines. The simplicity of Morse Code allowed for clear and concise transmissions, reducing errors and increasing speed, which was vital for timely communication in areas like journalism and military operations.
