Introduction

In today's world, few areas of our lives remain untouched by high-tech gadgets and computers. From our automobiles to the ubiquity of e-mail, the world of bits and bytes has overtaken every phase of our lives. While this ceaseless march of the tide of technology has brought wonderful benefits, as with all gains humankind has experienced, it also has brought some side effects.

Although our efficiency has increased, so have the demands for our time. Not only must we learn to multitask, but we must be available 24 hours a day. Tethered to our cell phones, personal digital assistants, and palm-top computers with twenty-first-century umbilical cords, loved ones and coworkers alike experience withdrawal symptoms and panic attacks if their calls and e-mails remain unanswered for more than 10 minutes.

Arguably nowhere has this technological onslaught had a greater impact than in the business world. E-mail, the World Wide Web, and corporate intranets have insinuated themselves into nearly every business. From the mom-and-pop market, which has a digital storefront to augment its brick-and- mortar operation, to the Fortune 500 multinational whose communications hub depends on the infrastructure of the network we call the Internet, digital traffic directs our lives—occasionally into unsightly rush-hour snarls.
