On device B, you edit the text. Another typical scenario is as follows: You are chatting with a customer on device A, and the customer asks for a file, which is stored on device B. You can use the chat software to open the file application on device B, select the required file, and send it back to device A. Then, you use the chat software to send it to the customer.

-[EventHub](../reference/apis/js-apis-inner-application-eventHub.md) provides an event mechanism for the UIAbility or ExtensionAbility component so that they can subscribe to, unsubscribe from, and trigger events.

 Before using the APIs provided by **EventHub**, you must obtain an **EventHub** object, which is provided by the [base class Context](application-context-stage.md).

 - In the stage model, all the UIAbility components in a process share one ArkTS engine instance. When using **globalThis**, do not store objects with the same name. For example, if UIAbilityA and UIAbilityB use **globalThis** to store two objects with the same name, the object stored earlier will be overwritten.
 
+- **globalThis** cannot be used across processes. The UIAbility and ExtensionAbility components of different processes cannot use **globalThis** to share data. For details about the process model and inter-process communication, see [Process Model Overview](./process-model-stage.md#process-model-overview).

 - This problem does not occur in the FA model because each UIAbility component uses an independent engine.
 
 - The lifecycle of an object bound to **globalThis** is the same as that of the ArkTS engine instance. To minimize memory usage, you are advised to assign the value **null** to the object when it is not in use.
