Реферат Web Site Development





to allow people to make new friends without any physical contact. One way to meet new people is to join an Internet discussion group. In such a group people with a common interest ask and receive advice and exchange information. Another opportunity to meet new people is in Internet chat rooms. In such rooms one can speak freely to anyone as if they were at a party. America Online users refer to relations charter though the sever as "AOL luv ". Those in discussion groups and chat rooms are not limited to just Americans but open to people all around the world. The Internet is a world wide tool filled with many cultures, and different people. In this world, race is not a factor since there is no physical contact. Everyone is equal and has the freedom to express oneself. It is an institution that resists institutionalization. It belongs to everyone and yet no one, everyone sort of pitches in and it evolves on its own. There are no censors, bosses, board of directors or stockholders. The Internet is unregulated and uncensored. However, the Internet being so free and uncensored presents many problems. Acknowledgment of children using the Internet has fueled a fight for regulation. Parents can not always monitor their children, therefore the Internet needs to be a safe place for the children. Children have access to the Internet in schools, libraries, and just about everywhere. In schools it is nearly impossible for a teacher to watch all the children, and in libraries it is not the librarian's job to monitor them. Computers and the Internet are for everyone, including children, thus it has become an immense problem. Access to pornography has been one of the greatest concerns among parents. Surprisingly, pornography is easy to access and children will. Children are naturally curious and love to explore. Minors are also targeted by advertisers. Just like on television advertisers try to lure children in with pictures and web sites which include games and chat rooms. However the biggest danger is not what they find on the Internet but who they find. The information they access is not as dangerous as the people they meet. There have been many cases of molesters and kidnappers searching for pray on-line. Nicknames are used to protect the identity of the children but can also be used to mask adults. They enter children's chat rooms and coax the children to trust them. Nonetheless, denying the children access to the Internet is not the solution, perhaps software is. However software limiting children's access to web pages have not been successful. In some case the software does not filter out all inappropriate pages but filters out non-objectionable pages. (Should children be kept off-line? n.page) Molesters and kidnappers are not the only people with access to the Internet we should fear. Those mischievous thinkers also pose a threat. Known as hackers or crackers, they search for vulnerable computer systems then strike. Businesses can lose trade secrets, and the damages can be a disaster. In 1996 Dan Framer, a security consultant, tested 2,000 computers networks, and of those 65% had security holes large enough for an intruder to enter (Freedman 280). Government computers are just a vulnerable as teenagers have recently demonstrated. Teenagers working out of their home with guidance from a 18 year old broke into government classified information. Though they were caught, it bought alarm to the possible dangers of information leaks. The United States ' enemies could have access to military codes and top secret files. Although the average person is not targeted by hackers they are in danger of fraud and con-artists. Stolen credit card numbers have been rumored to be a major problem. The chances of it happening are not as great as the media makes it to be, but nevertheless it is a problem. The criminals easily get away with such a crime. They get the number of a credit card and charge ridiculous bills, but by the time the bill comes they have moved on to the next victim. Many schemes come in the form of junk mail. They offer deals that sound too good to be true and chances are they fake. They only ask for a small sum of money up front, next they cash the check and move on. (Anarchy Online 98) Secure passwords can prevent hackers from accessing computers. Passwords should consist of numbers, letters and symbols: an example "P11 + +69." No matter how secure and high tech the computer security system, all it takes is a simple, stupid password like "hello" to render the whole system worthless. (Freedman 279) Though the Internet has its advantages it also has disadvantages, therefore users should educate oneself on the revolutionary tool. With over 50 million users the Internet is rapidly growing and is to the '90 's what the personal computer was to the 70's. New usage's are springing up everyday, making it impossible to predict the future of th...
