Introduction The World Wide Web is a
powerful tool for communicating ideas, facts and opinions. Without leaving
your desk, you can access and retrieve information on almost any topic. But the
Web can also be immensely frustrating, disorganized, chaotic, and
ever-changing. The trick to using the Web
effectively is to use the tools which will help locate available resources. There are many such tools: Web directories: a collection of Internet sites grouped into categories; using a directory is analogous to using the Yellow Pages or a library catalog. A directory is often the best place to begin Internet searching because it looks at a narrowed range of information. Search engines: based on keyword searches of databases that contain
millions of documents and words. Search engines provide quick access to
massive amounts of information.. A search engine performs more effectively
when you use a structured search
strategy. Meta-search engines: an outgrowth of search engines. Each
search engine accesses a portion of the Internet; while there may be overlap,
no two-search engines will return the same results to a query. A meta-search
engine accesses several search engines, thereby giving the broadest return to
a query. |
