moto gp xboxHTML4 had not been revised after was released 1999, face what the advance rapidly that Internet develops and multimedia apply to gain ground, the HTML4 standard that basically is aimed at character and picture is early cannot satisfy the new requirement such as Flash, video. The plug-in unit that is a delegate with Flash and patulous, promoted the capability of the browser, complemental the function that HTML4 place cannot provide, but the HTML5 language that is born formerly can have supplied most need entirely plug-in unit and patulous the function that will finish.

In addition, the cost of application development, safeguard charge to also will be reduced accordingly. Compose of the person that developer also can cast off dominant of existing operating system on certain level builds " enclosure type " regular. The application of HTML5 will make the browser becomes more extensive platform, the user can be finished through the browser all need to work in what PC finishs in the operating system before, can replace an operating system partly thereby, device of machine of hotshot of general Yu Zhi, flat reachs personal computer.
Shift letting the cloud becomes reality
ata pciHTML5 accords with prospective cloud computation to develop pattern. The user need not accept the restriction of all sorts of system platform and software plug-in unit, need to visit application through the browser only, still can pass long-range means to store al the most popular memory card digital cameras l sorts of content in the cloud, do not accept the restriction of the pos the best selling memory card digital cameras ition and equipment. In addition, the function of Application Cache API in HTML5 solv the most popular brooch pins ed problem of cloud computation stability well. Use program cache technology through this kind, the user perhaps appears in network defer below the circumstance of breakdown, still can use Web application normally. In the cloud computation popularizes today, the greater sense of HTML5 depends on, with its infinite and compatible and complete operation leaving a line, shift letting the cloud becomes reality increasingly.
The partial reason that HTML5 is valued depends on its flexibility, people believes this conduces to attract the development staff with considerable amount. Current, apple, Microsoft (small gain) , blackberry (small gain) the HTML5 in waiting for intelligent aircraft manufacturer to begin to support in new generation system, in addition, the Internet application provider such as Youtube, Facebook and domestic actor cruel, UCWeb also declares the support to HTML5 in succession.

furniture lightSafe, compatible still be difficult problem
On firm sense, HTML5 comes out not formally, it still is a draft only, its format standard still also is waited for perfect. As a result of open reason, HTML5 did not set the format standard of browser video, the manufacturer is OK the form that oneself choose to support, if at present the mainstream pays the H.264 of cost and free Theora encode, this makes HTML reveals the danger that code breaks free scooby costume up. Coexist in many browsers version, below circumstance of insufficient still to the support of HTML5 standard all-pervading, apply go up to still should consider to be offerred at the same time new old two kinds of pages. In addition, as a result of Flash have rate still stand high above the masses, the intelligent terminal that does not support HTML5 agreement still is used by broad user, HTML5 website developer must is same a video, prepare the version of two formats. In interim, the cost problem that these compatibility create or the promotion that make operation business does not wish to throw more funds to accelerate HTML5, and the c the most popular t mobile prepaid cards hoice that awaits an user passively. At present developer has not drafted the hardware interface order that gives to unite for HTML5, and the apple in mobile terminal market, Gu Ge, Microsoft, blackberry eachs does things in his own way, this without doubt will greatly people is opposite slow down the adoption of HTML5 speed.
HTML5 is called the substitute of prospective AdobeFlash, it can show frequency, graph and video effectively, but JamesLyne of advanced technologist of company of Sophos of British safety supplier the best selling scooby costume expresses, what potential HTML5 safe problem may affect this technology is rapid gain ground. If HTML5 function did not undertake correct process designing, safe flaw may make aggressor gets the visit limits of authority of pair of sensitive data.
