 ## Introduction<a name="section11660541593"></a>
 
-Distributed Scheduler is used for cross-device component management. It allows the local device to access or control remote components, and enables app collaboration in distributed scenarios. Its main functions are as follows:
+The System Ability Manager (SAMGR) subsystem implements the system service framework. It provides the functions of starting, registering, and querying system services, and querying cross-device distributed system services.
 
--   Remote ability startup: Starts an ability on a remote device.
--   Remote ability migration: Migrates an ability to a remote device.
--   Remote ability binding: Binds an ability on a remote device.
--   System service management: Provides system service startup, registration, and query on the local device as well as system service query on a remote device.
