At present we cannot imagine our life without the Internet. The Internet is necessary for each person. It is an integral part of our life. All people use the Internet on different purposes: for dialogue, for searching the information, for work, for studying, for fun and entertainment. We search something with the help of the searching engine. I think that the most important problem of the Internet is the addiction of people to it. Some people surf the Internet for many days and forget about their relatives and real life.
