## 25. Tasks

The Tasks section of the Dashboard currently has three tabs:

- Modules
- Definitions
- Executions

## 25.1 Modules

Modules encapsulate a unit of work into a reusable component. Within the Dataflow runtime environment Modules allow users to create definitions for Streams as well as Tasks. Consequently, the Modules tab within the Tasks section allows users to create Task definitions.

Note: You will also use this tab to create Batch Jobs.
