Evolution of Communication Technologies
The evolution of communication is as follows:
Telegraph and Telephone Era
The history of long-distance communication traces back to the telegraph and telephone, pivotal technologies that revolutionized connectivity. The telegraph played a crucial role in the colonization of the American West, while the American Telegraph and Telephone Company (AT&T) monopolized the telephone industry in the early to mid-twentieth century, driving urbanization in the United States.
Rise of Cellular Communication
Telephones, particularly cell phones, continue to dominate communication channels, especially in developing countries where satellite technology enables rural connectivity. The widespread adoption of cell phones underscores their accessibility and affordability, facilitated by advancements in satellite communication.
Optical Fiber Cable Revolution
The advent of optic fiber cables (OFC) marked a significant breakthrough in communication infrastructure. Telephone companies worldwide swiftly upgraded their systems to incorporate OFC, enabling rapid, secure, and error-free transmission of large data volumes. This transition paved the way for the digitization of information and the convergence of telecommunication with computer networks, giving rise to integrated systems like the Internet.
