The World Wide Web has hundreds of thousands of pages on virtually any subject. Nevertheless not all of these pages are authentic and there are scams and spams as to encounter as well. Most people use internet search engines to get the information they are looking for.These sites that are known as internet search engines are being designed to help people. This help comes in the form of listing relevant information sites in accordance with the browser’s needs. Of course not every site of that nature works in a similar manner. However despite these differences, there are three attributes that are being shared by all three sites. Firstly they search the entire internet on the basis of the search phrases that are referred to as keywords. Secondly they maintain an index of those search phrases as well as the whereabouts from where these were being found. Lastly the users are being empowered to search for words or combination of words in that index.In the initial phases of its existence, the internet used to get around one to two thousand enquiries from users all over the world. As for the current scenario, these enquiries have increased dramatically, having crossed the million mark already and going even further. In order for a search engine to locate a file or document, it must track the whereabouts of that particular topic on the web. There are special software robots that are referred to as spiders, which help in building lists of those words found on various sites. This process of building lists is known as web crawling. A lot of pages need to be looked into before a list is being constructed by a spider.The starting point for these special software robots are those lists that contain heavily used servers and those pages that enjoy a high level of popularity. The words that are being found on several pages of a popular website are being indexed. Other than that, the links found on those sites are also being noted down. This helps the spider in swift tracking of the popular web links that lead to the most heavily used portions of the World Wide Web.With the growing use of the internet, this whole process is reaching new levels of complexities nevertheless the job gets done for billions of people around the world. This heavy dependence on the web is not just limited to a certain region or a certain culture.
