新西兰计算机科学论文代写：系统的差异

手机的使用已经因为个人和职业的使用提高的原因。带上你自己的设备，加速了平板电脑和其他相关移动设备的使用。目前大多数移动设备都使用三种不同的操作系统，即苹果操作系统iOS、Android和Windows操作系统。有内部架构和基于用户的设计差异，使之更具吸引力。本文从系统架构和安全性的内在特征出发，分析了目标用户群、用户界面和性能的用户端差异，分析了这三种系统的差异。主要分析了非专家用户。
内部特征：安全性
iOS：iOS系统具有严格的安全政策虽然支持一定程度的用户访问和透明度（比彻et al，2011）。最安全的特点是加密到操作系统和安全软件是非常紧密连接的硬件和软件之间。只有违反引导内核，才会出现严重的安全漏洞，但紧密耦合使这几乎不可能。此外，应用程序运行在一个安全的沙箱，赋予它更多的保护。
安卓：Android手机用户使用了更多的自由，和增强的范围。用户可以设置访问权限，因为他们需要。数据安全功能再次加密到内核和应用程序沙箱也跟着来了，对于应用层的安全。
Windows操作系统：Windows也提供了应用强大的沙盒；此外，安全是其现有的安全协议的一个扩展应用的桌面。安全系统也与Active Directory和在线同步支持集成，使得安全性功能和更新可更新的。
用户端特性：目标用户组
Windows ：目标市场将包括诺基亚的用户和忠实的Windows用户。价格是Windows Mobile操作系统的优势，这将确保Windows也有大众市场。

The use of the mobile phone has increased because of both personal and career use reasons. Bring your own device to work has accelerated the use of tablets and other related mobile devices. Most of the mobile devices in current times are seen to use three distinct operating systems, which are the Apple operating System iOS, the Android and the Windows Operating System. There are internal architectural and user based design differences that makes one more appealing than the other. This essay analyzes the differences of these three systems based on the internal features of system architecture and security, and the user end differences of target user groups, user interface and performance. The analysis is mainly conducted for the non-expert user.The use of the mobile phone has increased because of both personal and career use reasons. Bring your own device to work has accelerated the use of tablets and other related mobile devices. Most of the mobile devices in current times are seen to use three distinct operating systems, which are the Apple operating System iOS, the Android and the Windows Operating System. There are internal architectural and user based design differences that makes one more appealing than the other. This essay analyzes the differences of these three systems based on the internal features of system architecture and security, and the user end differences of target user groups, user interface and performance. The analysis is mainly conducted for the non-expert user.Internal Features: Security iOS: The iOS system has a stricter security policy although supporting some level of user access and transparency (Becher et al, 2011). Most security features are encrypted into the OS and the security software is very tautly connected between hardware and software. Only by breaching the boot kernel, will there be serious security breach but the tight coupling makes this near impossible. Furthermore the apps run in a security sandbox which gives it more protection.  Android: The Android phone gives its user more freedom of use, and enhanced scope. The user will be able to set access permissions as is needed for them. Data security features are once again encrypted into the kernel, and application sandboxing is also followed here, for application level security.  Windows OS: Windows also provides robust sandboxing for its applications; furthermore the security is an extension of its existing security protocols as applied for its desktops. The security system is also integrated with Active directory and online sync support, making the security features and updates easily updatable.User End Features: Target User Groups Windows: The target market will include Nokia users, and loyal windows users. The price is an advantage for Windows mobile OS and this will ensure that Windows also has a mass market.
