 A component is a program that runs on Fuchsia in its own sandbox.
 Each component is a composable module that interacts with other components
 through their capabilities. All software on Fuchsia is defined as a component
-except for the kernel image, bootstrapping processes, and the Component Manager.

+组件是 Fuchsia 上运行在其自有沙盒中的程序。每个组件都是一个可组合的模块，通过其能力（capability）与其它组件交互。Fuchsia 中所有软件都被定义为组件，除了内核镜像、引导进程以及组件管理器（Component Manager）。
 
 Fuchsia's component framework is responsible for running nearly all user space
 software in the system. The Component Manager is a system process that coordinates
 the execution and lifecycle of all component instances, maintains the component
 topology, provides components with their capabilities, and keeps them isolated
-from one another.

+Fuchsia 的组件框架负责运行系统内几乎所有的用户空间软件。组件管理器是一个系统进程，它协调各个组件实例的执行和生命周期，维护组件拓扑，给组件提供相应功能，并使它们彼此隔离。
 
 Components obtain privileges to access various parts of the wider system through
 capabilities. Each component can declare new capabilities that they offer to the
 system and capabilities provided by other components (or the framework) that
 they require to function. Component Manager resolves and validates all capability
 requests between components to ensure they match capabilities that the component

+组件通过能力来获得访问更广泛系统的各个部分的权限。每个组件都可以声明其提供给系统的新能力，以及其运行所需的由其他组件（或框架）提供的能力。组件管理器解析并验证组件间的所有能力请求，以确保它们与组件已被正确授予的能力相匹配。
