VPN là một dịch vụ tạo kết nối được mã hóa từ thiết bị của bạn đến máy chủ VPN thông qua kết nối Internet của bạn. Hãy coi nó như một đường hầm xuyên qua một ngọn núi, trong đó nhà cung cấp dịch vụ Internet (ISP) của bạn là ngọn núi, đường hầm là kết nối VPN và lối ra là đến world wide web.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://blog.fuzzypn.com/kien-thuc-co-ba-n/vpn-la-gi.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
