, the working modes of memory and CPU have changed, and the concept of Front-End bus has become somewhat complicated. The Pentium 4 CPU uses quad pumped (4 times of concurrency) technology, which enables the system bus to transmit four times of data in a clock cycle, that is, the transmission efficiency is four times the original, it is equivalent to using four original front-end buses to connect to the memory. When the external frequency is still 133 MHz, the speed of the front-end bus is incre

these features and dynamically splice image URLs; 2) use the sizes and srcset attributes in HTML, the picture tag, or the image-set attribute in CSS to implement responsive images. Solution 1 is very simple. I skipped it here. solution 2 has many related articles on the Internet. If you are not familiar with it, you can search for "responsive images.
Here, let's take a look at the responsive Image Code (via) implemented by picture, sizes, and srcset mentioned in solution 2 ):

, the width of the division rate is reduced by 23. For example, 1024 width-23 becomes 1001.Note: Firefox or opear does not display the right scroll bar when the content is less than the browser height.So if the resolution is 1024, your page is not as secure as 1000. Set to 9,002 side blank larger, visually more comfortable. Also easy to do some floating layer design.If the resolution is 800, it is generally set to 770. But there are also set to 760.Th
with the same width, for example, 3 inch, if the density is 1.0, the resolution is 3 inch dip * X or 1.5 PX. If the resolution is, if the density is, resolution is 480*1.5 = px * X or dip * X. (Here X indicates the screen height ). if it is the same as 240dip, the two machines will show half the length, thus ensuring the proportion. in this case, if the resolution is 480 or 720, you can use the same layout file.
However, I have seen only 320*240 (0.75), 480*320 (1.0),

noticed that for a screen with the same width, for example, 3 inch, if the density is 1.0, the resolution is 3 inch dip * X or 1.5 PX. If the resolution is, if the density is, the resolution is 480*1.5 = 720px * X or 480dip * X.

There is a special form Element in the HTML element. We use it to collect form data and submit it to the server, and theoretically it is not rendered by any UI. Of course, if we keep up with a form behind the body element, it seems that there is no UI rendering problem, but when the form exists in other elements, there is a problem.
What's the problem? As shown in the following example, I need to control the page scroll bar because of the page layout. I hide the scroll bar of the body, and t
. The multi-finger touch does not have this effect. The screen size is 10.6 inch, and the resolution is only 1366*768. However, because of the use of Microsoft cleartype HD technology, the display effect is still quite outstanding, with brilliant colors and realistic image quality, if you are using a 1280*800 resolution 13.1 inch MacBook Air, I believe you will not be too disappointed with the surface RT.
