educators and students to use the Internet to search, retrieve, share and synthesize information. In its current form, Google has become a major driving force behind the information revolution in our society.In a nutshell, the Internet is a system of connected computers that allows individuals and organizations to use the World Wide Web to communicate with each other, search for information, and share and make use of it, often in collaboration with other users. Although the Internet is now more than 30 years old, its development has made possible, and even accelerated, the growth of many other technologies. For example, computers, which were typically used only by large corporations, have become affordable and accessible to nearly every household. As a result, they are increasingly being used in homes for a variety of activities, including work. In addition, businesses are finding it increasingly important to reach their customers and employees electronically rather than through physical outlets. As a result, companies are establishing a presence on the Web to reach their customers and customers are engaging in a variety of online activities. Although the Web has been used by both individuals and businesses for many years, it was not until around the early 1990s that the Internet was introduced to the general public. To date, the Web has grown rapidly. In 1993, the Internet had about 2.2 million sites in existence, according to The Encyclopedia of the Internet, a site published by the U.S. National Science Foundation (NSF) and The Associated Press. The figure had grown to about 5.6 million sites in 2001. It is estimated that in 2002, the number of Web sites is close to 60 million and is growing at a rate of around 5 million per month. The Web also supports a vast number of applications that are increasingly used for communications, commerce, education and other purposes. In addition, the Web has become an important tool for students, professionals and others to keep current with the fast-changing world of technology. How Google Works There are a number of tools on the Web that facilitate the search and retrieval of information. In addition, the Internet has become an important vehicle for sharing information. Web sites of interest are located, or indexed, by a search engine such as Google. A Google Web search is conducted by typing one or more search terms into a form on a Google page or clicking on a button labeled “Google.” Web pages are then listed according to their relevance to the search terms. Google uses over 60 search-related algorithms to rank pages by their relevance to search terms. Some of the algorithms use the links on a page as a way to determine which pages should be given priority. The search engine makes the results in the first three pages of the search appear when you type in a query. To increase the quality of the results, many Web sites now offer Google-indexed sites. When a person types in a query, Google uses a complex
