Author: Rochelle SanchiricoTelecommunication is the ability to send information over long distances. It’s the way we communicate with each other, whether we’re down the street or across the world. Telecommunications have been around since the earliest days of humanity, though the technology has changed a lot since then. Looking back, we can see how far communication has come.

They used smoke signals, drums, and horns to alert others of danger or guide them to a destination.
