It is no longer difficult to find and extract information from different sources. Internet, i.e. world wide web is one such place wherein you can get numerous information and you can find everything you want. Computer experts have made it easier for you to gather and find information. You don’t need to know the web address for everything you need to find but rather you can make use of search engines, like Google.

Only gathering the information and data is not enough, the same need to be organized or indexed in a particular way so that it becomes easier for the person in charge to find the information. The search engines have special embedded systems with the help of which they classify and segregate the data and the links on the basis of keywords or some other logic.
