 | Subsystem| A subsystem, as a logical concept, consists of one or more components. OpenHarmony is designed with a layered architecture, which consists of the kernel layer, system service layer, framework layer, and application layer from the bottom up. System functions are built from components, subsystems, and then to the system. In a multi-device deployment, you can customize subsystems and components as required.|
 | Component| A component is a reusable, configurable, and tailorable function unit. Each component has an independent directory, and can be built and tested independently and developed concurrently. |
 | hb | hb is an OpenHarmony command line tool used to execute build commands.|
-| HOBT | HOBT is short for HiLink SDK OHOS Basic Test. It is used to test the basic functions of the interfaces on which the HiLink SDK depends.|
-| Kit Framework | Kit Framework is the basic framework of Kit. It contains the security components of OpenHarmony and cannot be tailored.|
 | KV | A key-value pair (KV) is a format of data storage.|

 | 子系统 | 是一个逻辑概念，它由一个或多个具体的部件组成。OpenHarmony整体遵从分层设计，从下向上依次为：内核层、系统服务层、框架层和应用层。系统功能按照“系统 > 子系统 > 部件”逐级展开，在多设备部署场景下，支持根据实际需求裁剪某些非必要的子系统或部件。 | 
 | 部件 | 系统最小的可复用、可配置、可裁剪的功能单元。部件具备目录独立可并行开发、可独立编译、可独立测试的特征。 |
