The pros and cons of the browser kernel

Trident: This browser kernel is the kernel of IE browser, because in the early IE occupies a lot of market share, so this kernel is more popular, before a lot of web pages are based on the standard of this kernel, but in fact, this kernel to the true Web Standard support is not very good, even in 2005, With the standards established by the Web page Standard Development Organization (the Board) developed a disjointed, while Trident the kernel itself is more bugs, some of the Web page code support is not very good, this is more obvious in the earlier version of IE, such as IE5.5 (including IE5.5), In fact, IE6 to the standard of support is not very good, and we are now a lot of people are using IE6, in fact, it also belongs to a relatively early version.

However, due to the high market share of IE, Microsoft has not updated the Trident kernel for a long time, which resulted in two results
The 1,trident core is out of touch with the standard.
The 2,trident kernel of a number of bugs and other security issues have not been resolved, coupled with some experts and scholars to open their own view of Internet Explorer is unsafe, so many users began to turn to other browsers, Ff,opera is the rise of this period.
Gecko: This is the kernel used by Firefox and Flock, which has the advantage of being powerful, rich, and capable of supporting many complex web effects and browser extensions, but at the cost of a lot of resources, like memory.
Presto:opera uses the Presto kernel, the Presto kernel is known as the most popular browsing Web page of the fastest core, which is due to its natural advantages in the development of scripting languages such as JS script, will be about 3 times times faster than the other kernel, The disadvantage is that some web compatibility is lost in order to achieve fast speed.
Webkit:webkit is the kernel that Safari uses, but Safari is the browser under the Apple system (although there are also Windows edition, but relatively few), so simply introduce the advantages and disadvantages of this kernel, the advantage is that the Web browsing speed is faster, although less than Presto But also better than Gecko and Trident, the disadvantage is that the fault tolerance of the Web page code is not high, that is, the compatibility of the Web page code is low, will make some writing nonstandard page can not display correctly.
