At first glance, search engines such as Yahoo, Lycos, and WebCrawler seem to match some of the capabilities of basic agents. The key difference, though is that an agent is more interactive and can accomplish many tasks at many different locations. For example, if you search on a keyword using a search engine such as Yahoo, you will get a list of matches. You can then follow those links and possibly get your information. If you were to use an agent, on the other hand, the agent could submit your keyword(s) to many search engines, follow the corresponding links, and gather the information, all without any intervention from you, the user. It should be noted; however, that search engines have aided web users over the past years, yet it is time for the evolution of agents. Inherently, something faster, stronger, and more intelligent was likely to be developed, and it has.
