Considering that web application users use a wide variety of web browsers, web programmers must run compatibility and performance tests on various browsers before an app goes live. As a result, you'll have to install all the popular web browsers on the same computer, and you'll even have to run the same tests on all kinds of media devices (such like PC, smart phones and tablets) to simulate how an application works under different page sizes, resolutions and so on conditions. That is really head-scratching and very inefficient.

In the process of using Windows, we may have encountered such situations: the system restarts, shuts down or becomes blue screen, black screen without any warning or notice. Then you can no longer log on to the system, or get into an endless loop of blue/black screen + reboot. This case, you may first think that this is probably caused by hardware failures. However, that is almost always caused by conflicts between hardware drivers or errors of system kernel modules. The former is usually shown as a blue screen (+ restart), while the latter is usually shown as an automatic restart by default.

Opening multiple windows of Windows Explorer or interfaces of multiple programs is the basic operation that any computer user cannot avoid, which is not only a usage habit, but also to improve work efficiency. However, that actually reduces work efficiency to some extent. Because you'll have to go back and forth in a cluttered windows layout to find your target window and switch between them (the taskbar is crowded, the windows on desktop are overlapped).
