56.1 Introduction
The Internet and its applications can be seen as an integral part of the actual social development stage.
Without any doubt, the Internet has changed communication and information retrieval. This is enabled
by a rapidly developing set of technologies and easy-to-use applications, suitable for nearly all situations
of every day life. On the other hand, the broad and increasing application range has in turn advanced
technology development. The common and stable basis for Internet Applications is the Transmission
Control Protocol/Internet Protocol (TCP/IP) as the general, always and everywhere available—in this
sense ubiquitous—communication platform.
Internet Technologies is a common term for those technologies that represent the application-related
layers 5–7 of the Open System Interconnection (OSI) communication model [HZ80], relying on IP protocol
on layer 3 and the TCP or User Datagram Protocol (UDP) protocols at layer 4. Although it would
be technically possible, in most cases a clear separation of these layers inside a specific application is not
easy to achieve. However, this might be an additional benefit, since the slim application structures make
application development for Internet use rather easy.
The application of Internet technologies is tremendously influenced by the development of the World
Wide Web. Especially, Web browsers promise to be able to display nearly every type of data without any
additional software. They are available for every computing platform, are easy to install or are already
an integral part of operating systems. They are easy to use and provide access not only to static content
like the traditional Web pages, but also to dynamic content including multimedia. The actual trends
like Web 2.0 offer advanced technologies as well as platforms for social interconnections up to complete
virtual communities like “Second Life.” Of course, the trends sketched above also create drawbacks.
The problem that is mentioned most often is security. But without any doubt, Internet technologies have
changed human life.
