But the Web can also be immensely frustrating, with millions of webpages worldwide, the Web can appear to be disorganized, chaotic, and ever-changing. Instead of random surfing, the Web can be approached in an organized fashion. The trick to using the Web effectively is to use the tools which will help locate available resources and to map out a search strategy . A directory is often the best place to begin Internet searching because it looks at a narrowed range of information. Search engines are based on keyword searches of databases that contain millions of documents and words.
Search engines provide quick access to massive amounts of information.
Search engines are also known as crawlers, spiders, and worms. A search engine performs more effectively when you use a structured search strategy . Meta-search engines are an outgrowth of search engines. A meta-search engine accesses several search engines, thereby giving the broadest return to a query. Portals offer web directories, search engine access, free web-based email, and customized news, weather, and other information all on one introductory page.
