The major difference between them is the amount of time it takes to get the information. For example, if you wanted to download a video of the movie Jurassic Park, it would take about 16 days if you use a dial-up 28.8 modem. If you use ISDN, it would take about a week. Using a cable modem will reduce the time to one hour. Better yet, if you connected using fiber optic cable, your copy would be downloaded in three minutes.
Speed can be an important factor when accessing the Internet.
The Superhighway will experience some traffic jams. As more and more people begin using the Internet, the major pipelines will become clogged. If you are located on the East Coast, you may have already noticed that the Internet seems to slow down around lunchtime. This is about the time that Pacific coast users access the Net. Historically, California has always had one of the highest usages of the Internet.
