Mobile communication is the basis for one of the fastest growing business areas at the beginning of the 21 st century. With IMT-2000 (International Mobile Telecommunications 2000), high-speed communication is possible anywhere, at any time, to any communication partner, with almost any device. As IMT-2000 comprises a set of different networking technologies, it provides a communication framework in which a subscriber may freely roam without having to be concerned about which network to use [1]. Hand-over procedures seamlessly integrate in-house networks, campus-based networks, metropolitan and wide area networks.

Electronic communication has been redefining the ways in which people communicate with each other since its wide-spread introduction in the 1990’s. E-mail, instant messaging, internet forums, and social networking have added entirely new meanings to interpersonal interaction and community. Through time, internet based communication has developed its own set of non-verbal communication (emoticons, select usage of certain punctuation, chat speak, etc.) Like all other communication technologies, it has also been adapted into everyday life and everyday communication (by those that have access of course).

The rapid advent of “Web 2.0” applications has unleashed new HTTP traffic patterns which differ from the conventional HTTP request-response model. In particular, asynchronous pre-fetching of data in order to provide a smooth web browsing experience and richer HTTP payloads (e.g., Javascript libraries) of Web 2.0 applications induce larger, heavier, and more bursty traffic on the underlying networks. We present a traffic study of Web 2.0 applications including Google Maps, modern Web-email, and social networking Web sites, and compare them with all HTTP traffic. We highlight the key differences of Web 2.0 traffic from traditional HTTP traffic through statistical analysis. As such our work elucidates the changing face of one of the most popular application on the Internet: The World Wide Web.

Peer-to-Peer programming (P2P) has in recent years become a widely explored research area. With the evolution of wireless technology such as mobile phones, the idea to bring these two technologies together gives a new dimension to P2P communication, collaboration and resource sharing.

Technologies known collectively as Web 2.0 have spread widely among consumers over the past five years. Social-networking Web sites, such as Facebook and MySpace, now attract more than 100 million visitors a month. As the popularity of Web 2.0 has grown, companies have noted the intense consumer engagement and creativity surrounding these technologies. Many organizations, keen to harness Web 2.0 internally, are experimenting with the tools or deploying them on a trial basis.

This chapter presents a few of the thousands of mashups you can find today on the Web. No one knows how many other mashups live behind corporate firewalls, but, chances are, the number is large. The mashups in this chapter were chosen to show the variety of the world of mashups. Some of them are proofs-of-concept, others are works-in-progress, and others are experiments. Others are actual, live products or marketing tools. Mashups often provide visualization of information, and, frequently, that visualization is in the form of interactive maps. The release of the Google maps API was a major factor in the interest in mashups, in large part because so much information lends itself to mapping. As you will see in later chapters of this book, new technologies grouped together as Web 2.0 and AJAX are the building blocks of mashups. In conjunction with APIs such as Google mapping, eBay, Yahoo!, Flickr, and others, you will soon be able to build your own mashups like the ones shown in this chapter.

Nonaka and his knowledge transformation model SECI revolutionized the thinking about organizations as social learning systems. He introduced technical concepts like hypertext into organizational theory. Now, after 15 years Web 2.0 concepts seem to be an ideal fit with Nonaka’s SECI approach opening new doors for more personal, dynamic, and social learning on a global scale. In this paper, we present an extended view of blended learning which includes the combination of formal and informal learning, knowledge management, and Web 2.0 concepts into one integrated solution, by discussing what we call the Web 2.0 driven SECI model based learning process.

The concept of “Web 2.0” was born in the first Web 2.0 Conference organized by O’Reilly and MediaLive International in 2004. The concept was further elaborated in the article “ What is Web 2.0 Design Patterns and Business Models for the Next Generation of Software” published by Tim O’Reilly in 2005. Generally, Web 2.0 denotes the paradigm of employing the Web as the platform to deliver and use software. Nevertheless, what user experiences, design patterns and technologies Web 2.0 actually encompasses are not concretely bound and they keep evolving. As described in Wikipedia, “Given the lack of set standards as to what ‘Web 2.0’ actually means, implies, or requires, the term can mean radically different things to different people.”
