Today, when OS 4 is coming to the iPhone family soon, the most vivid discussion is the multi-task task. However, there is not much debate about the importance of multitasking tasks for ordinary users, but there are a number of questions on this topic, such as whether it will be useful for integrating the iPhone family into the network. Besides, does this multipurpose feature affect the media that recover most of the last mile of damaged bandwidth and accumulate with 90% spam?
Initially, the iPhone already has several tasks, so this is not such a new feature. Get in touch with incoming texts and phone calls while playing the music you are up to. The current version of iPhone OS uses a multi-tasking Mach / BSD kernel in the same way as Apple's desktop Mac OS X. Meanwhile, consumers see multitasking tasks as simultaneously more than one external program on desktops and laptops.
In fact, intensive multitasking tasks are indispensable even in terms of traditional security, convenience. This is not about the security of the device's appearance – that's what iPhone 4 can do. This is about software security. Think about it: Every time you create a Word document or something, you will find a number of security processes in the background, consuming valuable energy, and naturally sharing CPU resources and memory. At least, anti-virus software and anti-spam have to run continuously, while VPN and personal firewall provide the device together.
Consumers and companies typically run various versions of various security software for the highest rates of enemy code and activity detection. At the same time, the user is busy entering, listening or downloading the content. Thus, it is essential that tens of millions of users of Apple iPhone have multi-tasking in OS 4 because it seems that only one security point is critical. However, this is just a fake feeling and does not really matter. Apple can operate in the same way as Android and Windows Mobile, enabling any type of application to run when a user wants the same conflict problem package and system performance that is discovered on standard PCs. As Apple's A4 processor includes up to 4 cores, OS 4 will be able to separate internal system processes from others to a core while using others to manage third-party software.
Another potential view in OS 4 can take into account multitasking tasks that allow a third-party application, such as native Safari and email, to run simultaneously while allowing two, three or as many Apple proprietary apps to run , Command-Shift command to switch between them. In fact, defining multitasking tasks does not "run applications that the user wants." On the contrary, creating rational constraints to retain the user's positive user experience is a certain approach for mobile OS developers.
So what would happen to the security in this case? Actually, smart phones are only small computers and are already exposed to the same weaknesses as normal PCs and have just put the iPhone in jail. By the way, smaller devices win the design and look because they will not be able to put a colorful iPhone 4 cover on the Mac to increase the mood. But if you go back to software issues and imagine that Apple decides to run an unlimited number of security applications at a time (multi-task), it will imitate the security situation where the user is responsible for handling them all. In addition, each security application is loaded and starts from the endpoint. However, it has to be agreed that, although individual consumers need security and companies are required to comply, such an unlimited approach to security (even in OS 4 environment) faces a number of issues:
1. How long will it take for the battery, even the iPad, to load a number of security applications and keep running?
2. How high is the processing power and the storage rate required for the highest level of security?
3. Taking into account the preceding multiple tasks, which processes will take precedence over others, especially when they are able to exercise both safety and performance?
4. Assuming security is always running, users should start each security feature each time they turn on the device? Compared to OS X, consumers are able to select applications that are automatically launched at the beginning of "login items", and this feature is unreasonably wider in multipurpose tasks.
5. What skills and knowledge do the consumer have to find, install, configure, and monitor countless security applications?
6. When using the time-based security balance, how would the endpoint of a smartphone affect the cloud's performance over the last mile performance for richer content and security management?
7. What should the user do if the phone needs to turn off the night to start it in the morning? Suppose the consumer is only checking e-mail, but you have to wait until the multi-tasking iPhone ends.
8. Remember that the iPhone's resources are much more limited than traditional PCs, how often do you need to update security signatures, profiles, and alerts?
Since Apple's approach to available intelligence, it seems that Expose offers a user experience that allows them to switch between running applications more easily. However, it is not entirely clear that this means that the consumer will be able to watch the video on YouTube and then quickly switch to e-mail, favoring essentially pausing YouTube. It is possible for the kernel to handle multitasking tasks. But this approach still does not allow the device to be provided in the conventional way. And it does not matter which multi-task approach will be chosen for iPhone OS 4 or later if you do not handle security issues with traditional methods. It does not matter if you run iPhone 3 or 4, or even X or multi-tasking Symbian or Android operating systems, since it is clear that consumers can not rely on the phone service provider for safety, as no one thinks PC manufacturers are concerned about the entire digital century. In fact, providing current and future versions of foreseeable mobile technology is only a truly integrated, secure smart phone framework and architecture capable of working in the cloud.
So, when we look at a security point, it does not matter how Apple will design multi-tasking for OS 4. As the user experience prevails, we believe that most consumers do not dream of listing security at the top of the morning that they want to do in the morning. Imagine what can happen in a few years when more than 2 billion mobile users have chosen to provide the device only for iPhone 4, but not with useful applications. We find?
