# @ohos.WorkSchedulerExtensionAbility (Deferred Task Scheduling Callbacks) # @ohos.WorkSchedulerExtensionAbility (Deferred Task Scheduling Callbacks)
The **WorkSchedulerExtensionAbility** module provides callbacks for deferred task scheduling. The **WorkSchedulerExtensionAbility** module provides callbacks for deferred task scheduling. You can override the APIs provided by this module. When a deferred task is triggered, the system calls back the application through the APIs and processes the task logic in the callback.
When developing an application, you can override the APIs of this module and add your own task logic to the APIs.

The **workScheduler** module provides the APIs for registering, canceling, and querying deferred tasks. The **workScheduler** module provides the APIs for registering, canceling, and querying deferred tasks. You can use the APIs to register tasks that do not have high requirements on real-time performance as deferred tasks. The system schedules and executes the deferred tasks at an appropriate time, subject to the storage space, power consumption, and more.
