During the 1990s, data on the Internet was uniquely for perusing. It was a system of reports
and individuals couldn't interface with the substance. Almost everything that people used online was also part of the World Wide Web (www).
This was created during the primary decade of the 21st century. Right now, data got
bidirectional. Users could not only receive information, but also create and share it. New services appeared such as: email, chats, videoconferences, forums, blogs, wikis and
programs for person-to-person (P2P) file exchange, etc. Social networking was born.
From 2006 onwards, new technologies allowed the integration of data and the web so that
programs could understand' and work with the information that they received. The basis of technological evolution: artificial intelligence (AI); applications that do not use a
browser, such as smartphone apps; virtual reality; and Global Positioning System (GPS).

locate a particular snippet of data. To take care of this issue, an assortment of web indexes
have been structured that are site pages with a database of data about other site pages and
their substance. At the point when we search for data on the web, it is imperative to counsel
the pages that we know and trust and examine the data.
NEWS FEEDS: RICH SITE SUMMARY (RSS)

from media websites, blogs and other sources of information. RSS news sources are helpful and efficient. Since supporters get the news consequently, they don't need to visit such a significant number of sites. Individuals can buy in two different
