Dial-up Modem

A Dial-Up Modem is a classic networking device that connects computers to the internet using a standard telephone line. Once a primary means of accessing the web, dial-up modems convert digital data into analog signals for transmission over phone networks and then back into digital form for the receiving computer.

Though slower compared to modern broadband, dial-up modems were revolutionary in providing global connectivity during the early internet era. Even today, they are still used in remote areas, backup communication systems, and legacy applications where phone lines remain the only option.
