    Johnny Smith was a high school student. Johnny was a good mathematics student, a very good mathematics student. He loved his computer. He worked with it every evening after school. But Johnny was not a very good English student, not good at all. He got an F in his English class. One night after school, Johnny connected his computer to the computer in his high school office. The school office computer had the grades of all the students: the math grades, the science grades, the grades in arts and music, and the grades in English, Johnny searched through the school files. He found his English grade an F. Johnny changed his English grade from an F to an A. Johnny’s parents looked at his report card. They were very happy.

    “An A in English!” said Johnny’s Dad. “You’re a very smart boy, Johnny.”

    Johnny is a hacker. Hackers know how to take information from other computers and put new information in. Using a modem (调制解调器), they connect their computers to other computers secretly. School headmaster and teachers are worried about hackers. So are the police.  In the movie War Games, a high school hacker entered the computer of the United States Military.
