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).
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.
AMS
Ability Manager Service, a service that manages abilities
BMS
Bundle Manager Service, a service that manages application bundles
DevEco Studio for Embedded
Integrated development environment (IDE) for developing embedded devices
DMS
Distributed Management Service, a service used for distributed data management
FA
Feature Ability, representing an ability with a UI for interacting with users
HAP
OpenHarmony 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 for converting a configuration file into a file that can be read by the target software.
HDF
Hardware Driver Foundation that allows unified access from peripheral devices and provides foundation for driver development and management in OpenHarmony
IDN
Intelligent Distributed Networking, a distributed networking capability unit specific to OpenHarmony. You can use IDN to obtain the device list and device states and subscribe to the connection state changes of devices on the distributed network.
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.
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.
