"Karton" seems to be a topic of eternal use in Android phones, especially compared to the iOS system. The memory mechanism is one of the most important focuses. So we see that Android is constantly increasing the running memory of the system. Now 4GB has been basically popularized in the Android flagship machine. Even some manufacturers have released more memory models in succession (just released, there is no finished product listed), but it seems this It also did not completely annihilate the sound of Android Caton.
The more the mobile phone uses the card, and even becomes the laughing handle of the fruit powder, the core reason behind it is actually the legacy of history. The earliest Android prototypes mainly considered the keyboard machine design, ignoring the priority of the rendering interface; while the iOS system is more inclined to the touch screen model from the bottom layer design. The order of iOS response is Touch (Touch) - Media (Service) - Core (Core Architecture), the screen touch response priority, that is, when you touch the screen, the system will give priority to the screen display level. After that, it is the other; the Android response level is ApplicaTIon (Application) - Framework (Library (library, including screen response) - Kernal (kernel architecture), that is, when you click on the screen, the system will be busy first Activate the app, open the frame, and the third step will take care of the screen display. So Android is behind iOS from early design priorities.
Android system framework
However, Android does not know its own problems, so in the later stage, it is also trying its best to modify the architecture to adapt to touch operations. For example, in the Android 4.4 period, Google has been regarded as the chief culprit of Dalvik virtual machine mode that slows down the overall speed of Android. It is adjusted to the ART mode to improve the operating efficiency of the system. The brand manufacturer is also carrying it in its own ROM. Optimization, such as Huawei EMUI (representing products such as Huawei Mate8). But on the road of open source, compared with closed iOS, Android tends to be slightly indulgent in the memory management mechanism. In addition, many apps use unscrupulous memory resources, and increasing memory does not help, so we will often see Although the annual memory capacity is increased in a large span, the remaining amount of booting is always insufficient.
The biggest feature of Android is openness, but such openness is also easy to bring problems, which is one of the important reasons why Android has a card.
At present, many manufacturers have made a lot of efforts in optimizing Android. At present, there are more representative brands and products such as Huawei's Huawei Mate8 and so on. Of course, the world seems to have both sides. In the Android developer camp, there are always developers who don’t follow the rules of the industry. For example, if you install an app, it will be useless without your consent. The additional application, and the impact of fluency is that you open an application, it may even sneak in the background to run a variety of their own applications to drag limited hardware and other hardware resources, such rogue behavior is not uncommon in Android.
Android mobile phone will always be stuck, the memory is kept "eat"
The calling mechanism of system resources and the difference of management are the key to the fluency of Android system and iOS. However, the pursuit of fluency is necessary to strictly limit the entire ecology of Android. For the huge Android terminal, it is not worth the loss, but Google does not. It may completely disrupt the Android army that has been accumulated for many years, so at present, in addition to Google's continuous optimization of the Android system, we can only hope that the smartphone manufacturers in the Android camp can maintain and It takes a little more effort to promote mobile phone fluency, not just to upgrade it to the so-called 4GB or larger.
SFF-8644 cable is designed to connect storage devices, such as hard drives or solid-state drives, to a external device such as host controller or RAID controller. It supports high-speed data transfer rates and can typically up to 12 Gbps or higher.
