Search Engines

What is a search engine? Simply put, it is an internet tool designed to search for information in the World Wide Web (WWW). Did you know that the very first tool that was utilized to scan through the Internet for specific information was named ARCHIE? It was created and originally implemented back in 1990 by Alan Emtage, J. Peter Deutsch and Bill Heelan. ARCHIE search engine works by simply contacting a list of FTP (File Transfer Protocol) archive on a regular basis. By 1991, Gopher was created by Mark McCahill at the University of Minnesota. After that came several other search engines. Now, we have the convenience of using search engine tools for our research. However, among all those available, there are certain search engines that stand out among net users. I will mention later on the top search engine tools being utilized. For the moment, let see how web search engine works.
Search engines operates by following an order of interrelated tasks. First among them is web crawling. Web crawling is a program the browses the World Wide Web in a methodical automated manner. The web crawler that performs the act is also called ants, bots, web spider, web robot and many more. The second task is indexing. This is the portion wherein the crawler collects, parses, and stores data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, physics and computer science. The third and the last task of search engines is web search query. This query is what a user enters into the web search engine to satisfy his or her information needs. The search engines gather data based on the query posed and presents them to the Net user to look into. Having gone over that, let us now discuss the top search engine tools today. First on my list is Yahoo. I prefer to use Yahoo Internet portal because it provides news, email, music, shopping, web search, fantasy sports, and many other online products and services that make it convenient and useful for consumers and businesses. Second on my list is Bing, which was launched on June 01, 2009. I personally like Bing because it has a feature of daily changing background images. But then again, there is little difference to be recognized about the functionality of search engines. They all work great; it’s just that their features differ. And bottom line is, the effectiveness of the search will mostly depend on the type of key works you input on the search bar.
