With twice as many networks connected to the Internet as last year and a new one hooking up every 10 minutes,familiarity with the Internet will become increasingly essential to everyday life, says Mark Gibbs,co-author of "Navigating the Internet": "Not knowing how to use theInternet will be as grave a deficiency as not knowing how to read. The Internet will become the world's primary means of communication and will soon carry more mail than the entire postal services worldwide... The Internet now connects more people, resources and services than any other communications system except for the telephone system."
