Web sites can be operated by commercial companies, universities and other educational institutions, professional associations and trade groups, and government agencies as well as by employers, search firms, and staffing organizations. They are discussion areas on the Web. These forums are typically established by individuals who share a common interest or background. You can locate newsgroups for people who enjoy fly-fishing and for those who are looking for a job, for people who like to talk politics and for those who share a passion for gourmet cooking. The conversation occurs by e-mail and is open to everyone in the newsgroup, at the group's site.
Search engines are the workhorses of the Internet.
They visit Web sites and other online destinations to create a record of the information available there. Cyberspace is a big place that is expanding every day, and search engines help you to find exactly the data you need with a minimum of effort and time. You simply describe the subject in which you're interested, and the search engine uses those criteria to examine its files and identify those sites containing the appropriate information. No single search engine can possibly index all the information available at every site on the Internet. Databanks or databases.
