Dial-Up Modems
Dial-up modems use traditional copper phone lines to transmit analog signals. Out of all types of modems: dial-up, DSL and cable, dial-up connections offer the slowest transmission speeds.
What is a dial-up access?
Dial-up modem's connection is just like a regular phone connection, but instead
of people, computers are connected to both ends of the connection.
With a dial-up modem, the user must connect to his Internet Service Provider
(ISP) in order to connect to the internet.
