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).
An AbilityForm displays brief information about a Feature Ability on the UI of another application and provides basic interactive features.
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.
Ability Manager Service, a service that manages abilities
Bundle Manager Service, a service that manages application bundles
DevEco Studio for Embedded
Integrated development environment (IDE) for developing embedded devices
Distributed Management Service, a service used for distributed data management
Device Virtualization, which employs the virtualization technology to integrate capabilities and resources of different devices
Feature Ability, representing an ability with a UI for interacting with users
HarmonyOSOpenHarmony 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.
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.
HDF Configuration Generator (HC-GEN) is a tool for converting a configuration file into a file that can be read by the target software.
Hardware Driver Foundation that allows unified access from peripheral devices and provides foundation for driver development and management in HarmonyOSOpenHarmony
Intelligent Distributed Networking, a distributed networking capability unit specific to HarmonyOSOpenHarmony. 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.
Mobile Sensing Development Platform, which provides the capabilities of distributed convergence sensing and distributed device virtualization.
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.
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.
