1950s: The Beginnings of Artificial Intelligence (AI) Research |
 |
With the development of the electronic computer in 1941 and the stored program computer in 1949 the conditions for research in  artificial intelligence (AI) were given. Still, the observation of a link between human intelligence and machines was not widely observed until the late 1950s.
A discovery that influenced much of the early development of AI was made by Norbert Wiener. He was one of the first to theorize that all intelligent behavior was the result of feedback mechanisms. Mechanisms that could possibly be simulated by machines. A further step towards the development of modern AI was the creation of The Logic Theorist. Designed by Newell and Simon in 1955 it may be considered the first AI program.
The person who finally coined the term artificial intelligence and is regarded as the father of AI is John McCarthy. In 1956 he organized a conference "The Dartmouth summer research project on artificial intelligence" to draw the talent and expertise of others interested in machine intelligence for a month of brainstorming. In the following years AI research centers began forming at the Carnegie Mellon University as well as the Massachusetts Institute of Technology (MIT) and new challenges were faced: 1) the creation of systems that could efficiently solve problems by limiting the search and 2) the construction of systems that could learn by themselves.
One of the results of the intensified research in AI was a novel program called The General Problem Solver, developed by Newell and Simon in 1957 (the same people who had created The Logic Theorist). It was an extension of Wiener's feedback principle and capable of solving a greater extent of common sense problems. While more programs were developed a major breakthrough in AI history was the creation of the LISP (LISt Processing) language by John McCarthy in 1958. It was soon adopted by many AI researchers and is still in use today.

World Wide Web (WWW)
Probably the most significant Internet service, the World Wide Web is not the essence of the Internet, but a subset of it. It is constituted by documents that are linked together in a way you can switch from one document to another by simply clicking on the link connecting these documents. This is made possible by the Hypertext Mark-up Language (HTML), the authoring language used in creating World Wide Web-based documents. These so-called hypertexts can combine text documents, graphics, videos, sounds, and Java applets, so making multimedia content possible.
Especially on the World Wide Web, documents are often retrieved by entering keywords into so-called search engines, sets of programs that fetch documents from as many servers as possible and index the stored information. (For regularly updated lists of the 100 most popular words that people are entering into search engines, click  here). No search engine can retrieve all information on the whole World Wide Web; every search engine covers just a small part of it.
Among other things that is the reason why the World Wide Web is not simply a very huge database, as is sometimes said, because it lacks consistency. There is virtually almost infinite storage capacity on the Internet, that is true, a capacity, which might become an almost everlasting too, a prospect, which is sometimes consoling, but threatening too.
According to the Internet domain survey of the Internet Software Consortium the number of Internet host computers is growing rapidly. In October 1969 the first two computers were connected; this number grows to 376.000 in January 1991 and 72,398.092 in January 2000.
