key term - Telegraphy

Definition

Telegraphy is the long-distance transmission of textual or symbolic messages through a coding system, primarily using electrical signals. This revolutionary communication method laid the groundwork for modern electronic communications, connecting people and places that were previously isolated from one another. Its development was crucial for advancements in other technologies, such as radio, making it a cornerstone of the communication revolution in the 19th century.
