In order to bring these students back to their study from online activities like computer games, chatting etc., colleges are now taking preventive measures. Such measures include limiting students on computer hours, programming warnings on computer screens, creating workshops on the use of computers, and even involving the subject in orientation courses.At the University of California’s Berkeley campus, students are so addicted to cyber relationships that they forget their learning or in some cases, even get cheated out of money. It is really piteous that they feel lonely on the vast campus and consider the World Wide Web as the only safe connection to the world. And according to an examination of the dropouts made at Alfred University, the dropouts are found to have the common feature of excessive logging in, particularly late at night.Having realized the negative impact campus computers could have on students in their course work, American universities are now working to change the situation. Alfred University, for instance, has planned to warn the incoming freshmen of the dangers of excessive use of computers and keep a close watch on computer addicts on campus.II.
