An annual skills assessment survey reveals that, when it comes to the Internet, Americans are becoming more savvy.\n The MCI Great American Net Test was conducted online over a three-month period ending June 30. It produced an average score of 82 percent, compared to 78 percent a year ago.\n Which Americans are more Internet literate? According to the study both Baby Boomers (40 to 60 years old) and Generation Xers (24 to 39) averaged 84 percent. Those who access the Internet from home or work do better than those who access from school. And women (82 percent) have a slight edge over men (80 percent).\n Those who took the test were asked to use search technology to find answers on the World Wide Web. The questions were from the worlds of pop culture, world geography, history, arts and literature and science and technology.\n In addition, most Americans said that they expected the Internet to be around a century from now.\n MCI reports that more than 30 million computers have been linked to the Internet and the number could double by the year 2000.
