Overview: Modems Connect Our Digital Worlds through Analog Infrastructure
A modem allows digital computer systems like yours to send and receive data using existing analog telephone networks built for voice calls. It works by modulating digital signals into audible tones that phone lines can transmit, then demodulating those tones back into data at the other end.
This capability neatly bridges the infrastructure/technology gap to link digital machines remotely using ubiquitous, affordable telephone access. And over six decades that simple functionality provided infinite value:
- Businesses shared data instantly between branches and HQ
- Military bases coordinated strategy and responses in real-time
- Scientists analyzed results from remote facilities
- Consumers accessed online services and Internet from home
- We all connected digitally despite physical distance
Let‘s explore the history of this small but mighty technology that wired our world together!
