Passage 1

the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new

road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families

connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled

highway. Traffic jams can cause many serious problems, forcing the system to close down for repair.
