# How a node works

For example, a component can convert a **YouTube video into text**. In this case, a video is provided as input, and the component takes over the transcription to generate text output. 

A component contains inputs as mentioned above, but also advanced configurations that provide different functionality, such as adjusting the flow cache or the precision of the answer.

Use a component to perform one task in a workflow. Each component receives data, processes it, and returns a result.

## **How a node works**

Each component usually has:

* **Input:** the data it receives
* **Nodes:** the advanced configurations you choose
* **Output:** the result it produces

Connect the output of one node to the input of the next one to build your flow.

For example, a node can turn a **YouTube video into text**.
