The term “web 2.0” refers to the growing focus on collaborative, interconnected, user-generated content that distinctly altered the way Internet users spent time on the World Wide Web

which allowed users to create individualized profiles as a part of a network of friends and contacts, also effectively became file-sharing outlets. Videos uploaded to the file-sharing site youtube.com could be easily posted on Facebook or Myspace and shared among friends.

Connecting Cultures For the same reasons but in a far different environment, social studies teacher Suzie Nestico oversees a project that involves 14 schools and nearly 400 students in Australia, Canada, England, Germany, South Korea, and the United States. She teaches students in grades 10 through 12 at the 900-student Mount Carmel Area High School in Mount Carmel, Pa.

She also built a course called 21st Century Global Studies that started this academic year. The course is for students in grades 10 through 12 who, through project- and inquiry-based assignments such as editing wiki pages, learn that working collaboratively with other cultures—an increasingly marketable skill—can be challenging. “It’s a big shift for them to go from ‘me’ to ‘we,’ ” she said. “I can’t help but think that the more kids we involve in projects like this, the more we start to break down some of this sense of entitlement” that exists among students in the United States. “Just imagine if you wrote 200 words on your wiki page, and when you went back the next day, you saw that students in Korea had changed a couple of your sentences because they thought it sounded better another way,” Ms. Nestico said. “There are a lot of sighs at first, and it’s a messy process, but it’s very much worth doing. This is where we truly push learning to the highest level.” Some lessons have less to do with a final grade than with understanding that a simple phrase in one culture can easily be misperceived in another. When a student in California posted an online request last summer for information about a “flash mob,” for example, a teacher from Germany immediately jumped in to write that European students couldn’t even talk about such a thing because of the London riots. And two years ago, during an education-related trip to Mumbai, India, Ms. Nestico had to nix any exclamatory T-shirts that might offend the local residents, such as “Holy cow!,” because cows are considered sacred animals in India.

While an independent contractor at CERN from June to December 1980, Berners-Lee proposed a project based on the concept of hypertext, to facilitate sharing and updating information among researchers.[9] While there, he built a prototype system named ENQUIRE

In November 2009, Berners-Lee launched the World Wide Web Foundation in order to "Advance the Web to empower humanity by launching transformative programs that build local capacity to leverage the Web as a medium for positive change."

Cost savings — The lowering of the overall cost of the service to the business. This will involve reducing the scope, defining quality levels, re-pricing, re-negotiation, and cost re-structuring. Access to lower cost economies through offshoring called "labor arbitrage" generated by the wage gap between industrialized and developing nations.[10] Focus on Core Business — Resources (for example investment, people, infrastructure) are focused on developing the core business. For example often organizations outsource their IT support to specialised IT services companies. Cost restructuring — Operating leverage is a measure that compares fixed costs to variable costs. Outsourcing changes the balance of this ratio by offering a move from fixed to variable cost and also by making variable costs more predictable. Improve quality — Achieve a steep change in quality through contracting out the service with a new service level agreement. Knowledge — Access to intellectual property and wider experience and knowledge.[11] Contract — Services will be provided to a legally binding contract with financial penalties and legal redress. This is not the case with internal services.[12] Operational expertise — Access to operational best practice that would be too difficult or time consuming to develop in-house. Access to talent — Access to a larger talent pool and a sustainable source of skills, in particular in science and engineering.[13][14] Capacity management — An improved method of capacity management of services and technology where the risk in providing the excess capacity is borne by the supplier. Catalyst for change — An organization can use an outsourcing agreement as a catalyst for major step change that can not be achieved alone. The outsourcer becomes a Change agent in the process. Enhance capacity for innovation — Companies increasingly use external knowledge service providers to supplement limited in-house capacity for product innovation.[14][15] Reduce time to market — The acceleration of the development or production of a product through the additional capability brought by the supplier.[16] Commodification — The trend of standardizing business processes, IT Services, and application services which enable to buy at the right price, allows businesses access to services which were only available to large corporations. Risk management — An approach to risk management for some types of risks is to partner with an outsourcer who is better able to provide the mitigation.[17] Venture Capital — Some countries match government funds venture capital with private venture capital for start-ups that start businesses in their country.[18] Tax Benefit — Countries offer tax incentives to move manufacturing operations to counter high corporate taxes within another country. Scalability — The outsourced company will usually be prepared to manage a temporary or permanent increase or decrease in production. Creating leisure time — Individuals may wish to outsource their work in order to optimise their work-leisure balance.[19] Liability — Organizations choose to transfer liabilities inherent to specific business processes or services that are outside of their core competencies.

Mosaic is the web browser credited with popularizing the World Wide Web. It was also a client for earlier protocols such as FTP, NNTP, and gopher. Its clean, easily understood user interface, reliability, Windows port and simple installation all contributed to making it the application that opened up the Web to the general public.[2] Mosaic was also the first browser to display images inline with text instead of displaying images in a separate window.[3] While often described as the first graphical web browser, Mosaic was preceded by the lesser-known Erwise[4] and ViolaWWW.

Wireless network refers to any type of computer network that is wireless, and is commonly associated with a telecommunications network whose interconnections between nodes are implemented without the use of wires.[1] Wireless telecommunications networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or "layer" of the network.
