Essentially, you practice continuous computing, surrounded by a movable information network.This network is created by constant cooperation between the digital devices you carry(e.g., laptops, media players, and smartphones); the wired and wireless networks that you accessas you move about; and Web-based tools for fi nding information and communicating andcollaborating with other people. Your network enables you to pull information about virtuallyanything from anywhere, at any time, and to push your own ideas back to the Web, fromwherever you are, via a mobile device. Think of everything you do online, often with yoursmart phone: register for classes; take classes (and not just at your university); access class syllabi,information, PowerPoints, and lectures; research class papers and presentations; conductbanking; pay your bills; research, shop, and buy products from companies or other people; sellyour “stuff”; search for, and apply for, jobs; make your travel reservations (hotel, airline, rentalcar); create your own blog and post your own podcasts and videocasts to it; design your ownpage on Facebook; make and upload videos to YouTube; take, edit, and print your own digitalphotographs; “burn” your own custom-music CDs and DVDs; use RSS feeds to create yourpersonal electronic newspaper; text and tweet your friends and family throughout your day; andmany other activities. (Note: If any of these terms are unfamiliar to you, don’t worry. You willlearn about everything mentioned here in detail later in this text.)
