Seminar paper from the year 2012 in the subject Communications - Research, Studies, Enquiries, grade: 1,3, Institut for Interpreter and Languages Munich, course: Search engines, language: English, abstract: At present, there are approx. 614 million registered Hostnames2 and approx. 184 million active websites, corresponding to the available statistics of the web analysis service Netcraft.3 The latter value does not refer to single websites belonging to everything for this IP-address, but identified Internet addresses only on these by a single IP-address. This answers a inquiry and distribute a website. The number of all websites cannot easily estimate, because of many factors like the strong size differences and dynamic websites. If one searching at Google for the concept or WWW one gets a value of over 25 billion of websites delivered, which seems to be almost realistic. 4 After statistics of internetworldstats.com5 almost 2.2 billion people (approx. 32 percent of the world population) using the Internet today, thereby is the number in the past 11 years increased by 528 percent. In Europe, approx. 500 million people are using the Internet, of these around 67 million in Germany. According to this in Germany, there are meanwhile more than 82 percent of the citizens, which are using the Internet.

Different languages, expired information, differently format for example documents, music, video or pictures, fall under this. In addition, it can be obstructive due to the steady updates of the contents to regain the same information at a later occasion. Out of the introduction, it gets obvious, that the abstract of searching and finding by search engines brings already many questions with themselves. Because of the expected extent, this work cannot answer the topic and possible questions profoundly and extensively and rather serves fundamental researches for further work.
