Abstract :
A few years ago, Sun Microsystems used the slogan, "the network is the computer," to promote its products and to alert people to a profound change in computing-use models. With the growth in cell phones, digital cameras, portable music players, wireless e-mail, GPS sensors, and automotive map displays that rely on wired and wireless networks, you might be tempted to say "the network is my post office, my map, my stereo system, my photo album..." and so on.
