What Is A Modem And What Does It Do?

The video tutorial explains the function of modems and routers in connecting computers to the internet. A modem modulates and demodulates signals to enable communication between digital computers and analog telephone lines. It is essential for internet connectivity. Routers, on the other hand, allow multiple devices to connect to the internet and communicate over a local network. Modern routers often combine the functions of both a modem and a router, simplifying the setup for users.
