The Road Fast Traveled

Coming to terms

It's a jungle of abbreviations and acronyms out there. Here's your quick-glance guide to sorting the broadband vocabulary out:

Cable modem: modem that connects to the Internet over cable TV lines

Dial-up: accesses a network via a regular phone connection; operates at up to 56Kbps

DSL: digital subscriber line; works over normal copper phone lines; operates at up to 1.5Mbps Fractional T1: purchasing the use of only some of the 24 64Kbps channels that make up a T1 line

ISDN: integrated service digital network; like DSL, it works over regular phone lines; operates at up to 64Kbps Mbps: million bits per second

T1: dedicated connection capable of speeds of up to 1.5Mbps

T3: faster than T1 lines; high-speed T3 lines comprise the "backbone" of the Internet
