What is the Deep Web
Surface Web and its Benefits
There is a big influence of technology on our daily life. Electronic devices, multimedia and computers are things we have to deal with everyday. The Internet, especially, is becoming more and more important for nearly everybody as it is one of the newest and most forward-looking media and surely -“the”- medium of the future. (Markus Temmel, Martina Theuermann, Eva Ukowitz, and Tanja Vogrin 2001)
The future is here, and we live it every day by waking up and grabbing the device that is nearest to us, looking at the screen and confirming that this will be a nice day. All of this is only possible because of the Internet. According to the Freesoft Encyclopedia this untouchable (maybe touchable with touchscreen devices) interactive multimedia library has made human life easier and faster for the last 18 years. It was created in 1969 by the Defense Department with the purpose of wartime digital communication. It was called the DARPA Internet Program. But the Internet as we know it now was reformed, modified,and commercialized in early 1990, and the World Wide Web (WWW) was introduced. (Brent Baccala, Kyle Hourihan, 2012)
It takes about five seconds to find anything on the web. It is as easy as typing some label words, pressing the enter key, or -cliking the “search” button-, and a couple million options will appear on the screen. This process has become more simple over time and new microphone and voice recognition software enables disabled people to dictate to their Internet connected device, what is that they want to see, hear, or read. Introduction to the Deep Web
But is the search engine showing all of the results available? This is a question that is rarely posed, but I found the answer, and it is: No.
According to Luisiana State University, when you use a search engine like Google or Yahoo!, the information you get back is sometimes referred to as the "Surface Web" or the "Visible Web." However, there's a lot more information out there - There are millions of web pages that Google and Yahoo can't find. That's the Deep Web. For example, a Google search will not pick up all information in the Library of Congress web pages. To find those web pages you would have to go to the Library of Congress home page and perform a search there. So, why can't you find those pages with your Google search?; Search engines like Google cannot fid Deep Web pages because they are within specialized databases. Typical search engines simply aren't allowed to access them. The Deep Web is made up of valuable material, like the information within the Library of Congress web pages. In January 2006, Marcus P. Zillman wrote -the Deep Web covers somewhere in the vicinity of 900 billion pages of information located through the World Wide Web in various files and formats that the current search engines on the Internet either cannot find or have difficulty accessing. The current search engines find about 8 billion pages-. (Louisiana State University, 2008)
The Deep Web (also called Deepnet, the invisible Web, DarkNet, Undernet or the hidden Web) refers to World Wide Web content that is not part of the Surface Web, which is indexed by standard search engines.
Mike Bergman, credited with coining the phrase, has said that searching on the Internet today can be compared to dragging a net across the surface of the ocean: a great deal may be caught in the net, but there is a wealth of information that is deep and therefore missed. Most of the Web’s information is buried far down on dynamically generated sites, and standard search engines do not find it. Traditional search engines cannot “see” or retrieve content in the Deep Web – those pages do not exist until they are created dynamically as the result of a specific search. The Deep Web is several orders of magnitude larger than the surface
