www Clients or "Broswers"

The program you use to access the WWW is known as a browser because it "browses" the WWW and requests these hypertext documents. Browsers can be graphical, like Netscape and Mosaic, allowing you to see and hear the graphics and audio; text-only browsers (i.e., those with no sound or graphics capability) are also available. All of these programs understand 

http and other Internet protocols such as FTP, gopher, mail, and news, making the WWW a kind of "one stop shopping" for Internet users.

 

Chatting:

Internet Relay Chat (IRC), the other method for Internet conversation, is less common than talk because someone must set up the Chat before others can join in. Chat sessions allow many users to join in the same free-form conversation, usually centered around a discussion topic. When users see a topic that interests them, they type a command to join and then type another command to choose a nickname. Nicknames allow people in the session to find you on IRC Networks or Channels.


 

A look at search engines:

The World Wide Web is "indexed" through the use of search engines, which are also referred to as "spiders," "robots," "crawlers," or "worms". These search engines comb through the Web documents, identifying text that is the basis for keyword searching. Each search engine works in a different way. Some engines scan for information in the title or header of the document; others look at the bold "headings" on the page for their information. The fact that search engines gather information differently means that each will probably yield different results. Therefore, it's wise to try more than one search engine when doing Web searching.

The list below lists several search engines and how each one gathers information, plus resources that evaluate the search engines.
