Intelligent Agent - These computerized software programs perform activities such as retrieving and delivering information as well as automating repetitive tasks. "Scripting" and "macros" are in the same general category as Intelligent Agents. As an example, when your e-mail program automatically transfers e-mail you receive from a relative, to a special folder you chose for e-mail from that relative, your e-mail program is using a type of "intelligent agent." Intelligent Agents are extensively used on the Internet.
