This article describes an online platform for educators with free open source educational systems including wikis, blogs, bulletin boards, Content/Course Management Systems, and MOOs, all open systems which are easily installed and managed. By setting up a content-based server, educators can save and archive their files online easily, and integrate their online resources without needing web design skill. With full control of these different educational tools, educators can form a collaborative learning community based on their teaching goals. Thus teachers and students can build an online community as partners. They can learn from and with others, share and try out web learning tools, distribute leadership and inspiration, and support and interact with others from all over the world.

It began life under the name ARPANet in 1969. It was born in the U.S.A., created in the midst of the Cold War by the government as a strategic mechanism that would provide for the emission and reception of electronic communication signals in the event of a world catastrophe. Commissioned by the Department of Defense, four computers called nodes were connected using modems, telephone wires and satellites, one each at UCLA, UCSB, Stanford and University of Utah. ARPANet stands for Advanced Research Projects Agency Network. Its purpose was to share information and results of research among the various scientists involved in Department of Defense projects. Each node was specifically designed io be independent of the others in case of that aforementioned world catastrophe.

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.

Current search engines such as Google and Yahoo! are prevalent for searching the Web. Search in dynamic pages, however, is either inexistent or far from perfect.

They are increasingly frequent on the Web (in YouTube, Amazon, GMail, Yahoo!Mail) or mobile devices and are offering a high degree of interactivity to the user, by seamlessly loading content from the server without the need to refresh the page. Current search engines cannot correctly index AJAX applications. This produces false positives and false negatives, because search engines do not understand the application logic that loads content dynamically. Crawling an AJAX application is a difficult problem. Since the user invokes events on the page, crawling must identify the different application states generated by the client-side logic.
