The computer is a featureless black wedge. It does not have a power cord, but there is a narrow translucent plastic tube emerging from a hatch on the rear, spiraling across the cargo pallet and the floor, and plugged into a crudely installed fiber-optics socket above the head of the sleeping Vitaly Chernobyl. In the center of the plastic tube is a hair-thin fiber-optic cable. The cable is carrying a lot of information back and forth between Hiro's computer and the rest of the world. In order to transmit the same amount of information on paper, they would have to arrange for a 747 cargo freighter packed with telephone books and encyclopedias to power-dive into their unit every couple of minutes, forever.
