Write one to three paragraphs explaining how inventors in the field of communication improve on each other’s earlier designs.

Answer:

Inventors improve communication by studying existing inventions and solving their limitations. Samuel Morse developed Morse code, which used dots and dashes to represent letters and allowed messages to be sent over a telegraph. Granville Woods improved telegraph technology by creating systems that allowed messages to be sent more efficiently, including communication between moving trains and railway stations. Alexander Graham Bell built on earlier telegraph ideas by working to transmit sounds instead of coded signals, leading to the telephone. These inventions show how later inventors use earlier designs as a foundation and adapt them to make communication faster, clearer, and more useful.
