Is Web surfing with ISDN really that much faster than with a modem?
Yes. Web surfing with ISDN is fast, and the connection setup time is quick when compared to a modem. However, Internet performance is only as fast as the weakest link. In theory, a 64 kbps ISDN connection should be twice as fast as a 28.8 kbps modem, and nearly ten times faster than a 14.4 kbps modem. However, the speed at which data gets from a Web server to your computer is dependent on many things, so ISDN is no sure fix for Web surfing stress, but it is one less weak link in the chain. If your ISP is running over capacity, or the Web site you’re accessing is busy, you’ll still have to put up with the World Wide Wait, as the server sending your data responds to requests from other users, transfer rates vary–sometimes wildly.
