CLOUD COMPUTING
Cloud computing has received a lot of popularity in the last few years and market observers believe it to be the future, but not if security problems persist.
For people who are not familiar with cloud computing, it is the practice that involves usage of network servers that are remotely located. Users can access the remote servers via the Internet to manage, store and process relevant data, rather than on the personal computer of a local server.Many businesses are using cloud computing that usually turns out to be cheaper, faster and easy to maintain. Now, not only businesses but regular Internet users are also using cloud computing services such as Google Docs, Dropbox and more to access their files whenever and wherever they want.Cloud computing has accelerated with the wide use of the Internet services as well as development of mobile devices such as smartphones and tablets. Many people carry their portable devices when not on their desk and easily access their documents, media and pictures on cloud storage via the Internet.With the development in technology market, experts are also worried about the increased security needs for cloud computing. "There's no more debate," says Rajat Bhargava, co-founder of JumpCloud, a cloud security startup. "When you don't own the network, it's open to the rest of the world, and you don't control the layers of the stack, the cloud - by definition - is more insecure than storing data on premises."Some members of Open Data Center Alliance, a consortium that includes top IT companies of the world such as SAP, Infosys, Deutsche Telekom, Disney and more, are believed to be cloud enthusiasts. However, a recent survey of the members reveal that around 66 percent of the consortium's members are concerned regarding data security, which is deferring their efforts for cloud computing. A similar survey done in previous years indicated that around 80 percent of the members were skeptic about entering cloud computing due to security concerns.
Security issues over cloud computing is definitely one of the major concerns that many companies are trying to recognize. However, some companies are also concerned about regulatory issues. Market observers say that 47 percent of the participants in the survey worry that they will be tied to one provider of cloud storage.
Amazon Web Services is a prominent cloud computing provider in the industry. The department is the fastest growing department of Amazon. However, in Oct. 2012, services failed for a while. Users who had their files stored with Amazon Web Services were unable to access their documents.
Experts opine that cloud computing is at its nascent stage and providers will have to address issues related security, availability, and more to expand in the future.

WEB 3.0
Some Internet experts believe the next generation of the Web -- Web 3.0 -- will make tasks like your search for movies and food faster and easier. Instead of multiple searches, you might type a complex sentence or two in your Web 3.0 browser, and the Web will do the rest. In our example, you could type "I want to see a funny movie and then eat at a good Mexican restaurant. What are my options?" The Web 3.0 browser will analyze your response, search the Internet for all possible answers, and then organize the results for you.
That's not all. Many of these experts believe that the Web 3.0 browser will act like a personal assistant. As you search the Web, the browser learns what you are interested in. The more you use the Web, the more your browser learns about you and the less specific you'll need to be with your questions. Eventually you might be able to ask your browser open questions like "where should I go for lunch?" Your browser would consult its records of what you like and dislike, take into account your current location and then suggest a list of restaurants.

To understand where the Web is going, we need to take a quick look at where it's been. Keep reading for a quick lesson on the evolution of the Web.
WEB 4.0
Web 4.0 is still an underground idea in progress and there is no exact definition of how it would be. Web 4.0 is also known as symbiotic web. The dream behind of the symbiotic web is interaction between humans and machines in symbiosis. It will be possible to build more powerful interfaces such as mind controlled interfaces using web 4.0. In simple words, machines would be clever on reading the contents of the web, and react in the form of executing and deciding what to execute first to load the websites fast with superior quality and performance and build more commanding interfaces. Web 4.0 will be the read-write-execution-concurrency web. It achieves a critical mass of participation in online networks that deliver global transparency, governance, distribution, participation, collaboration into key communities such as industry, political, social and other communities . Web 4.0 or webOS will be such as a middleware in which will start functioning like an operating system . The webOS will be parallel to the human brain and implies a massive web of highly intelligent interactions. Although there is no exact idea about web 4.0 and its technologies, but it is obvious that the web is moving toward using artificial intelligence to become as an intelligent web.
ONLINE EDUCATION
Online education can be defined as an approach to teaching and learning that utilizes Internet technologies to communicate and collaborate in an educational context. Online education has become increasingly more popular due to its flexible access to content from any place at any time. Different technology applications are used to support different models of online learning. Asynchronous communication tools (e.g, e-mail, threaded discussion boards, newsgroups) allow users to participate in an online course at their convenience. They can participate at any time and from any place. Synchronous technologies (e.g. webcasting, chat rooms, desktop audio/video technology) allow the instructors to maintain the synchronous interaction in their online courses. Students are expected to login at the same time but can participate from any place
Students seeking to take online classes or earn a degree online may do so for several reasons. For students with jobs and families, time is a factor. Online courses offer adult learners the opportunity to further their education and to acquire relevant job skills without having to spend time traveling to a campus or to a workshop site. The flexibility of many online courses also allows students to take control of their learning by working it into their busy schedules when it is convenient. Online courses are often less expensive than face to face courses, so the financial aspect of distance learning is attractive to students, because they not only save on fees and tuition but they also save on expenses like transportation and housing.
EDUCATIONAL ADVANTAJES
§ Enhancing student-to-student and faculty-to-student communication.
§ Enabling student-centered teaching approaches.
§ Providing 24/7 accessibility to course materials.
§ Providing just-in-time methods to assess and evaluate student progress.
§ Reducing administration around course management.
Online education opens a lot of doors for students who reside in rural regions or whose local universities and colleges do not offer courses that they are interested in. For some, fully online programs are the only way that they can take the classes that are required for a certain degree or enter a program that they desire.
