The imac screen resolution is divided into two types, 21.5 inches 1080P Full HD, while the 27-inch version has a higher 2560*1440 resolution. In addition, Apple added a low glare coating last year and ensured the accuracy of the screen color. And in the actual use, you will find that the screen brightness when the basic can not see the reflection phenomenon, the visual angle is also very good, of course, if the background light is too br
In the current notebook computer, there are more and more new products start to carry 1080P Full HD screen, 1920*1080 Pixel high resolution for the user's experience to upgrade is obvious. However, the current smartphone is already in the 5-inch display area to provide 1080P resolution, so notebook manufacturers are also pursuing higher standards. For example, the delicate impressions of an Apple MacBook pro,15.4 inch 2880*1800 pixel with a retina display would have overshadowed those 1080P note

Abstract:
WEB application capacity planning: WEB service planning and some simple estimation formulas based on hardware configuration and WEB application characteristics;APACHE
For android game development, we have to think about compatibility with Android tablets like the iPhone. Apple needs to consider the compatibility between iPad, iPhone 3gs, and iPhone 4 screens, which is no exception for Android game development, more models are considered.
In general, we may only consider qvga, hvga, WVGA, fwvga, and dvga. However, if we leave the phone blank, we may use a tablet like wsvga's 1024x576 and wxga's 1280x768.
Qvga = 320*240;Wqvga = 320*480;Wqvga2 = 400*240;Wqvga3.
