According to reports, computer analyst Isaac Glenn, who earns $120,000 a year organizing and upgrading computer networks, does not know how to fashion crude tools or grind wheat. 'I guess to grind wheat, you'd probably cut it off the stalk and then maybe use some kind of crushing device to mash it until it's powder,' Glenn said. 'I don't really know what you'd do with it then. Maybe cook it, I guess.' Glenn added that network administrators should use jacketed, certified cat-5 cable and keep runs perpendicular to electrical lines to prevent data integrity problems in 100BaseT networks.
