Microsoft has confused the order of the release of Windows 8, Windows RT and a Windows Phone 8, which in addition to similar names, have a common interface, but runs on a completely different devices. Do not add clarity and a word about the “common core” of a W8 and WP8.
It is really a version of Windows deficit this year is observed. By the above mess should also add Windows 8 Pro, which is due to start immediately abbreviations to be confused with Windows Phone 8. The first step is to divide “window” on the platforms. Windows 8 and Windows 8 Pro runs on regular laptops and computers. They are also able to work on tablets and hybrid computers, provided that they are based on the processor Intel. But the thin, lightweight and standalone tablet is powered by an ARM-architecture, and for them is released Windows RT. The same processors used in smart phones, but smartphones have a separate OS – Windows Phone 8. Despite the similar interface and a “common core”, all operating systems – different. Only on Windows 8 run older applications on Windows 2000, XP, 7, etc. In Windows 8 and Windows RT run the same application if they are specially designed for the family “eight”. But some applications for smartphones.
Then what is the “salt” of the common core, if the applications are different? Will begin with an explanation of the surface, and what is this very core. In fact, it is the part of the operating system that addresses the most important and basic tasks: resource management, application switching, communications programs, “iron” device. Core – the most important, but a very small part of the operating system. Changing the rest of the operating system, you can make the system inconsistent, despite the common core. For example, Linux, iOS and Android have let not common, but closely related kernel, which does not prevent them to be fundamentally different. In the case of Microsoft, of course, the situation is much more interesting. The core and the many add-on it, for example, system drivers, really look at Windows 8 and Windows Phone 8. The differences are due to the fact that fewer resources Phone 8, the other (though very similar), graphical interface and also imposed additional restrictions on multitasking – in order to save battery life, traffic, and other resources.These differences are enough to make the tablet and smartphone applications incompatible. But work on some other alteration is simplified. If you create a new application for Windows 8 / Windows RT, then using the same development tools they can turn it into a smartphone app for Windows Phone 8. That is what counts Microsoft, this is important “obscheyadernost” for developers. But there is in this community pleasant consequences for ordinary users.
First and foremost a pleasant consequence – more open to the hardware system modifications. Multi-core processors (64 cores!), Screens and high-definition camera, a slot for SD-cards – all this is possible and not burdensome to the new kernel. Moreover, I assume that with a few modifications hacking in Windows Phone 8 will run USB-host, that is, a cable adapter to your phone can connect flash drives, keyboards, and maybe even printers. Not that this was the main functions of the smartphone, but sometimes it can connect accessories urgently needed.
Second, the most important thing – more powerful applications. In WP7 application roles were very hard – or this supervidzhet (Silverlight), or toy (XNA), or a simple background application, able to carry out just a couple of problems. In WP8 for background processes are also restricted, but they are less stringent, so that we can see and full navigation software, which continued to lead the route, even if the user switches to another application, and the clients IP-telephony, running constantly and not really affect the battery. In addition to the advanced features of multi-tasking, it is essential the emergence of “native” applications that contain direct instructions of the processor, not pseudo Silverlight / XNA. This untie the hands of developers who can create a computationally complex applications, had not in the scope of templates Microsoft. For example, applications that recognize the photographed text directly on the device or perform complex processing photos. These pieces in WP7 can only be written in the format of “cloud” service, where calculations themselves are on the server.WP8 change this situation for the better.
Third pleasant consequence “obscheyadernosti” for users, more niche – Microsoft cannot tolerate excessive force on the Windows Phone the necessary functions of the “big» Windows, even if we are not there. For example, if tomorrow the need to implement full encryption of all data in memory or run security policies for corporate smartphones, these modules quickly ported from “adult» Windows.The same applies, for example, support for multi-user settings. It may seem that they are embodied in the “Children’s Room”, but in fact, this useful feature does not create a separate user with its own set of data, and for good reason.
Briefly summarizing, I will say that the “common core” does not make Windows Phone 8 compatible with Windows 8. But here’s an opportunity to get the latest “iron” and hope for a solid number of functional software – provides exactly.
