  • Dial-up modem — An older type of Modem that connects a computer to the Internet via a standard telephone line. Typically a dial-up modem connects to the Internet at a very slow data transmission speed of only 56 Kbps, whereas a modern Broadband modem connects to the Internet at 512 Kbps or much higher. Because dial-up access uses normal telephone lines, the quality of the connection is often poor. See Kbps.
