One way to use the Internet is by surfing, the process of following links from one Web page to another. It can be a lot of fun, but simply surfing the net does not necessarily get us where we need to go. In this lesson we will look beyond basic surfing to quicker ways to find information on the Internet, namely directories and search engines.

Surfing can be interesting and fun, but it is frustrating if you do not find what you are looking for. There are popular web sites that you can go to that provide a lot of information on topics such as these. We find out about these types of web sites in various ways, such as from TV, radio and magazines.

Some web sites contain large amounts of
information on a single subject. These sites
tend to cover fewer topics than popular
directories, but
generally do so in depth.
A good example of this
type of site is the NASA site.

Portal sites refer to Web sites that provide a starting place for finding information on the Internet. Many portals began as simple directories or search engines, but they have added features over time. A portal may be a directory, a search engine or a combinationof both.

Directories try to bring order to the
Internet. However, directories are
limited because the Internet is so
big. Directories
are still a
good place to start.

Search engines find information for us by matching specific words to information on the Internet. While it can be tricky to learn how to use them well, search engines can locate obscure information that does not appear in a directory.
