Modem:(MOdulator-DEModulator) Until the late 1990s, the term stood for a device that allowed a computer or terminal to transmit data over a standard dial-up telephone line. Since the advent of high-speed cable and DSL connections, modem may refer to devices for low-speed dial-up or high-speed broadband.
Broadband:(1) High-speed transmission. The term commonly refers to Internet access via cable and DSL, which is as much as 400 times faster than analog dial-up. The term has always referred to a higher-speed connection, but the speed threshold varies with the times. Widely employed in companies, the 1.5 Mbps T1 line was often considered the starting point for broadband speeds, while the FCC defines broadband as a minimum upload speed of 200 Kbps.
