+A
+-
+
+-  **Ability**
+
+   An ability is an abstraction of a functionality that an application
+   can provide. Abilities of applications are classified into two types:
+   Feature Ability (FA) and Particle Ability (PA).
+
+-  **AbilityForm**
+
+   An AbilityForm displays brief information about a Feature Ability on
+   the UI of another application and provides basic interactive
+   features.
+
+-  **AbilitySlice**
+
+   An AbilitySlice is the combination of a single visualized UI and its
+   interactive logic. AbilitySlice is the fundamental unit of a Feature
+   Ability. A Feature Ability can contain a group of UIs representing
+   closely associated services, and each UI corresponds to one
+   AbilitySlice.
+
+-  **ACE**
+
+   Ability Crossplatform Environment, an environment for abilities to
+   run across platforms
+
+-  **AMS**
+
+   Ability Manager Service, a service that manages abilities
+
+B
+-
+
+-  **BMS**
+
+   Bundle Manager Service, a service that manages application bundles
+
+D
+-
+
+-  **DevEco Studio for Embedded**
+
+   Integrated development environment (IDE) for developing embedded
+   devices
+
+-  **DMS**
+
+   Distributed Manager Service, a service used for distributed data
+   management
+
+-  **DV**
+
+   Device Virtualization, which employs the virtualization technology to
+   integrate capabilities and resources of different devices
+
+F
+-
+
+-  **FA**
+
+   Feature Ability, representing an ability with a UI for interacting
+   with users
+
+H
+-
+
+-  **HAP**
+
+   HarmonyOS Ability Package, released as a HAP file. One HAP file
+   describes all content of an application, including code, resources,
+   third-party libraries, and a configuration file.
+
+-  **HCS**
+
+   HDF Configuration Source (HCS) describes the HDF configuration using
+   key-value pairs. HCS is designed to decouple configuration code from
+   driver code, thereby facilitating configuration management.
+
+-  **HC-GEN**
+
+   HDF Configuration Generator (HC-GEN) is a tool used to convert the
+   configuration text into the target. In the HarmonyOS kernel, it can
+   convert the configuration file into the configuration tree of C
+   programming source code. The driver then directly invokes the C
+   programming code to obtain the configuration.
+
+-  **HDF**
+
+   HarmonyOS Driver Foundation that allows unified access from
+   peripheral devices and provides foundation for driver development and
+   management in HarmonyOS
+
+I
+-
+
+-  **IDN**
+
+   Intelligent Distributed Networking, a distributed networking
+   capability unit specific to HarmonyOS. You can use IDN to obtain the
+   device list and subscribe to the connection state changes of devices
+   on the distributed network.
+
+M
+-
+
+-  **MSDP**
+
+   Mobile Sensing Development Platform, which provides the capabilities
+   of distributed convergence sensing and distributed device
+   virtualization.
+
+   -  Distributed convergence sensing: Backed by the distributed
+      capabilities of HarmonyOS, the MSDP integrates the sensing sources
+      of all involved devices to accurately sense users’ space status,
+      motion status, gestures, and health status. It thereby builds
+      ubiquitous basic sensing capabilities, bringing smart life
+      experience to users.
+   -  Distributed device virtualization: Backed by the distributed
+      capabilities of HarmonyOS, the MSDP virtualizes various components
+      (such as cameras, monitors, speakers, and microphones) of
+      peripherals into the components available for local devices. Also,
+      it enables local devices to share their components with other
+      devices.
+
+P
+-
+
+-  **PA**
+
+   Particle Ability, representing an ability without a UI. PAs are
+   invoked to implement Feature Ability (FA) functionalities. For
+   example, a PA runs in the background to provide the computing
+   capability or acts as a data warehouse to provide the data access
+   capability.
+
+S
+-
+
+-  **SA**
+
+   System Ability. The system abilities include the basic hardware and
+   software services provided by the OS.
+
+-  **Super virtual device**
+
+   Also called super device. It integrates the capabilities of multiple
+   devices through the distributed technology into a virtual hardware
+   resource pool and then centrally manages and schedules these
+   capabilities based on application requirements.
