Motorola recently developed a cable modem that runs at 30 Mbps -- 30 megabits per second. Just for comparison's sake, a fast modem will go 28.8 kbps; the Ethernet connections to all dorm rooms run at a maximum of 10 Mbps; and the University's connections to the Internet, a pair of T1 lines, run at 1.544 Mbps each!
This device may turn out to be the start of the much overhyped "Information Superhighway". But don't plan on getting yourself a cable modem any time soon: they cost roughly $600 apiece, and that's only for 10 Mbps!
