WebCT was originally developed at the University of British Columbia by a faculty member in computer science, Murray W. Goldberg. In 1995 Goldberg began looking at the application of web-based systems to education.[2] His research showed that student satisfaction and academic performance could be improved through the use of a web-based educational resource, or web-based course tools (from which the name WebCT is derived). In order to continue his research he decided to build a system to ease the creation of web-based learning environments. This led to the first version of WebCT in early 1996, first presented at the 5th international World Wide Web conference in Paris during the spring of 1996. In 1997 Goldberg created a company, WebCT Educational Technologies Corporation, a spinoff company of UBC.[2] Goldberg grew the company until 1999, at which point it served approximately 2-3 million students in 30 countries. In mid-1999, WebCT was acquired by ULT (Universal Learning Technology),[2][3] a Boston-based company headed by Carol Vallone. Ms. Vallone continued to grow the company to the point where its product was used by over 10 million students in 80 countries.[2] Goldberg resigned from his position of Canadian president of WebCT in 2002. In February 2006, WebCT was acquired by rival Blackboard Inc.[4] As part of the acquisition terms with Blackboard, the WebCT name will be phased out in favor of the Blackboard brand.

WEB CACHE COMMUNICATION PROTOCOL
WCCP allows utilization of Cisco Cache Engines (or other caches running WCCP) to localize web traffic patterns in the network, enabling content requests to be fulfilled locally. Traffic localization reduces transmission costs and download time.
Contents
Allows for use across up to 32 routers (WCCP servers) Supports up to 32 engines/accelerators (WCCP clients) Supports any IP protocol including any TCP or UDP Supports up to 256 service groups (0-255) Adds MD5 shared secret security Primary WCCP functions
Redirect from Router to Cache EngineWCCP GRE redirect creates tunnel from router to local or remote Engine WCCP L2 redirect rewrites packet MAC address to that of the local Engine Redirect list allows router to permit/deny traffic to intercept
Return from Cache Engine to RouterWCCP GRE return WCCP L2 return Engine can optionally return traffic any other way including routing

WEB CALLBACK
In some implementations the Web Callback service provider will place outgoing calls to the owner of the web site, and the user, then connect the calls together. An alternative approach is for the web site owner to receive a SMS text message, so they can initiate the call to the web site user.
Some Web Callback service providers allow the Callback form to be embedded into the web site, sometimes matching the look and feel of the existing site. Others, simply add a hyperlink to the site, which is linked to the service providers own site.

PAGE RANK
PageRank is a link analysis algorithm used by the Google Internet search engine that assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is also called the PageRank of E and denoted by PR(E).
In other words, a PageRank results from a "ballot" among all the other pages on the World Wide Web about how important a page is. A hyperlink to a page counts as a vote of support. The PageRank of a page is defined recursively and depends on the number and PageRank metric of all pages that link to it ("incoming links"). A page that is linked to by many pages with high PageRank receives a high rank itself. If there are no links to a web page there is no support for that page.
Google assigns a numeric weighting from 0-10 for each webpage on the Internet; this PageRank denotes a site’s importance in the eyes of Google. The PageRank is derived from a theoretical probability value on a logarithmic scale like the Richter Scale. The PageRank of a particular page is roughly based upon the quantity of inbound links as well as the PageRank of the pages providing the links. It is known that other factors, e.g. relevance of search words on the page and actual visits to the page reported by the Google toolbar also influence the PageRank. In order to prevent manipulation, spoofing and Spamdexing, Google provides no specific details about how other factors influence PageRank

WEB BOT PROJECT
Recently, this technology; widely referred to as "The Web Bot Project" has been used to make a great deal of debatably accurate predictions about human society as a whole.
Some predictions the Web Bot has made include:
Predictions made toward a military background in the Washington D.C. Sniper spree Loose references to the Spaceshuttle Colombia tragedy References were made to Vice President Dick Cheney, involving a gun shot wounding A major event was predicted in the time period days around the 9/11 attacks. McCain would end his campaign in September 2008 for health reasons (which turned out to be true for one week, but for the health of the economy not his own) Louisiana would experience an "electrifying" water experience that will drive 300000 people away from shore (Hurricane Rita did this, however the post-event comments was how "shockingly fast" the water rose in the city.) As noted in the last two predictions above, the Web Bots are good at identifying events but sometimes the words don't match what actually occurs and thus require careful interpretation.

WEB DOCUMENTRY
Compared to a linear narrative where the destination of the story is pre-determined by the filmmaker, a web documentary provides a viewer with the experience of moving through the story via clusters of information. The integration of information architecture, graphic design, imagery, titles and sub-titles all play a role in providing visual clues to the viewer as to the sequence through which they should move through the web documentary. But from that point, it becomes the viewer's discretion to poke their heads into the nooks and crannies of the project, exploring the components of the story that interest them the most.

WEB CAM
Today there are millions of webcams that provide views into homes, offices and other buildings as well as providing panoramic views of cities (Metrocams) and the countryside. Webcams are used to monitor traffic with TraffiCams, the weather with WeatherCams and even volcanoes with VolcanoCams. Webcam aggregators allow viewers to search for specific webcams based on geography or other criteria.
