本文主要讲的是系统的介绍，本系统是在开源Chromium OS项目下部分开发的，其中代码只支持谷歌，不支持开发人员，仅在设计的软件上执行。本项目的设计文档描述了基于窗口管理器、浏览器、固件和系统级软件以及用户服务的三层架构(Geer, 2009)。通过消除对硬件的探测，固件可以提高引导时间。在系统恢复过程中，启动过程中的每一步都要经过验证，这对系统的安全组件也有贡献。本篇代写文章由英国论文时Essay Times教育网整理，供大家参考阅读。
This system is developed partially under the project of open source Chromium OS wherein the code is only Google supported and not developers and performs on the designed software only.

The contribution is also made to the security component of this system as each step within the process of boot is verified while incorporation of the recovery of system.
The software of system level involves kernel of Linux which is patched for enhanced boot performance (Gray, 2009). Software of userland as well is minimum to the essentiality with the Upstart management as services can be launched in parallel, crashed jobs can be respawned and services can be deferred for faster boot time. Window manager further takes care of the interaction of user with different windows client. This system works only on Chromebooks that are netbooks with hardware integration of processor that are either ARM based or x86. It is also requested by the organization of the system to its partners of hardware that only the solid state drives are employed for the purpose of increased reliability and performance (Singh, 2006).
