Cloud Computing is the combination of Distributed Computing, Parallel Processing and Grid Computing, or also know as the computer science concept of business.

Many multinational company such as the information technology industry, Yahoo and Google IBM’s use of the concept of cloud calculative selling their products and services. Cloud calculative this term may be borrowed from the quantum physics of Electron Cloud “(” Cloud), emphasize that the calculation of diffuse and omnipresent distribution and social characteristics. In quantum physics “probability cloud)”, electron (around the nucleus in electronic is not a sport such as the rail track objects, but as the space, cloud filled the existence of the movement is described, electronic Newton classical mechanics but a probability distribution density function, use the schrodinger equation to describe fluctuations within the time specified, the probability of a particle size, with the formulation of the classical mechanics is totally different. Has the following characteristics of cloud, however, diffuse, simultaneously, etc., may indeed is calculated from the clouds cloud concept, this is the so-called “before the Ubiquitous computing”, IBM has a Ubiquitous computing is Ubiquitous “, “MS (Bill) soon followed a Ubiquitous computing” Pervade “, people is right now Ubiquitous computing is a new understanding, now say “Omnipresent”. However, the cloud calculative is purely commercial hype, it will change the pattern of information industry, now many people already use Google Apps and Google Doc, USES the many remote software applications such as word processors Office rather than with your local machine install these applications, who will buy Office software? There are many enterprise applications such as e-commerce applications, such as to write a transaction procedures, Google’s enterprise scheme and contains the templates, a salesperson didn’t study Netbeanr also can make. This calculation and industry trends is the source of the spirit, with a Service SaaS (on) the trend. Now, there’s only five computers in the world today, is a Google, one is the IBM, is a Yahoo, one is amazon.com, is a Microsoft, because these five company takes the lead in the distributed processing business applications on the leading the trend. From very early computer network is proposed that “is prescient.

Browser is an application that this application provides a browse and visit in World Wide Web (WWW Web), all of the information. As a professional term now “the origin of the word browser” earlier than the Web, it is to let you online browsing through operation box (read) text files of the user interface.

Technically, a Web browser is a client applications, it is representing browser user use HTTP Protocol (Hypertext spread through the network Protocol request to the Web server. Most browsers have support for E-mail and File Transfer Protocol (FTP Protocol File, spread a Web browser, but for those Internet Protocol (IP), the Internet is not available. But more specifically the client application is more popular than the browser.

The First Web browser, called WorldWideWeb browser, 1990. The browser name later renamed Nexus browsers, it is in order to avoid and a developing information space, the famous World Wide Web (WWW Web) between the confusion. The first with a graphical user interface (GUI), with the graphical browsers, it is called the Mosaic in 1993. In many of the user interface Mosaic browser features of the company in the United States Netscape Navigator WEB browser in application. Microsoft then developed it IE (Internet Explorer browser).

From September, 2006, IE (Internet Explorer browser) is the most commonly used browser, it won the browser wars in the so-called (IE Explorer and Netscape between the browser wars). Other browser include:

Firefox Mozilla browser, it is made of the open source software (browser version) and Netscape.

The browser, it makes a Flock of open source web browser, is based on the browser and optimize the Firefox Web2.0 the browser features, such as: blog (disappointed) and social bookmarks (SB, social bookmarking).

The browser, it makes a Safari used Apple computer (AC), Apple in the browser (according to ranking, the popular browsers ranked third).

It is a browser, Lynx for Unix operating system user’s pure text VMS and text, the browser (browser - how TOB.

Opera browsers, it is a fast and very stable, and the browser compatibility, most browsers also related to the operating system.

Bulletin board system, electronic bulletin board system as the BBS. Electronic bulletin board system is on the network information sharing or exchange of computer or application. Electronic version of the bulletin board system was originally in many kitchen or place of work began on the wall, it was used to use in simple information between users. BBS in international Internet started to use before the 1980s and early 1990s became a major media online.

Through dial-up modem BBS, remote login or Internet access. Because it in a graphical user interface (GUI) widely used before, so the interface is based on the BBS text. Despite recent based on the Internet version of the graphic user interface are interactive, but through remote login user preference BBS text interface. According to the Sceiron company founders and early system operators, Justin, Scott’s point of view, based on the Internet in the BBS is essentially through the BBS software instead of the web server.

Although some are essentially the same, but most are dedicated to a specific topic BBS. In the special topic on the BBS, legal, guns, dental multiplayer game, zadok’s activities and disabled information. There are a number of BBS site provides much “, “dialogue and downloadable photos. Although some BBS to member or user fee, but most are free of charge. Many, many WEB sites have BBS Internet connection with new users can also provider to download necessary software by connecting the BBS. BBS has its own culture and rules. For example, a system is running this website operator. Through the BBS for chatting online is more and more popular, and there are many abbreviations from here to spread.

The first BBS, called the computer bulletin board system (CBBS), Christensen and Randy Ward of Suess in 1978. Although ARPA nets were used, but confined to the department of defense. When CBBS appeared on the Internet, immediately became the military’s computer based on the different media, timesharing system (will host a processing time assigned to the computer). Christensen and Suess in an uploaded file in the journal article describes CBBS and their use of technology, and lit the world to create thousands of BBS.

Regardless of how widespread use of the Internet as a medium, BBS with its ability in Internet immature and network connection of local higher fees are still quite common parts.

WiMAX aka (Worldwide Interoperability for Microwave Access) Microwave Access authentication industry Interoperability major league members include equipment manufacturers, suppliers, operators, etc, the device for main task is through product authentication, compatibility and Interoperability standards applied to eliminate the IEEE802.16 obstacles, expand the scope of application of standard. 802.16 is developed by IEEE802 wireless technology air interface standards, representative of the standard including 802.16 d fixed wireless access and 802.16 e mobile wireless access standards. According to the current situation of technological development, 802.16 d mainly located in enterprise users, provide the means of transport, and long 802.16 e user groups are located in the individual user, support users in mobile broadband network condition.

WiMAX is an emerging technology, can be in more than Wi-Fi within the scope of the vast area “last kilometer” broadband connectivity, which support enterprise customer service and residents enjoy T1 user has to cable/DSL access. Relying on its site in any 1 ~ 6 miles coverage (depends on many factors), WiMAX will provide for high-speed data more excellent mobility. In addition, depending on the coverage and high throughput rate, WiMAX can provide for telecommunications infrastructure, enterprise zone and WiFi hotspot provide return.

WiMAX will be divided into three stages deployment. The first stage is through indoor antennas to deploy IEEE802.16 d by the standard WiMAX technology, target users is fixed locations known subscriber. The second phase will deploy indoor antennas, WiMAX will appeal to broaden the technology for simplifying the operator user: installation. The third stage will be launched in the IEEE802.16 e, WiMAX specification authentication hardware will be used in portable solutions for those who hope, in service, the user support similar roamed in today’s Wifi ability, but more lasting WiFi solid connectivity.

The primary challenge WiMAX face is still the construction cost and price. Currently MMDS multicast channel, including distributed system WiMAX antenna deployment, cost as much as $3,000 for each user, which not only makes operators difficult to obtain enough investment returns, the user will tremble for China, besides, wince GHz 3.5 this resource is limited band of MMDS broadband wireless access system, after several rounds of scheme updates and technology innovation, various equipment has quite high performance-to-price ratio, WiMAX if the price according to the above similar to participate in the competition will be facing serious challenges. In addition, WiMAX and Wi-Fi, 3G in quite a long time, and each will be in the overlapping area to a certain extent, the competition among these systems, maintain efficient and enhance its interworking is facing the competition WiMAX important tasks.

Web 2.0 became popular, more and more attention of the public and the application effects on the Internet, and sharing of knowledge, and by one-way development for interactive, users can easily and quickly get information.

Because information sharing, effective and efficient interaction to share is very important, at the same time, it also has the function of mutual comments, sharing website set up in succession, information sharing and application in the main content, can be classified into different information, including site, documents, photographs, video and application software sharing and interactive platform, etc.
