I will try to help you, but you need to be more specific in your question.
The Internet or web as some people call it has become one of if not the best invention of the century.
Regardless of type of work you are in it has become a must. Hospitals use it to get info on new medicines (reactions and interreactions with other medicines), schools use it to get info on subjects not found in their school books, regular people use the Internet to stay in touch with their loved ones.
But this great invention has its bad sides just like its good ones. For instance children or adults can download pornography which our religion bans. Also some sick people use it send wrong information about certain subjects, to confuse people. The Internet can also be used to obtain private information on certain people.
So, as you can see, the Internet is not without its ups and downs. The main thing is to use it to your benefit and not to hurt anyone.
