## 磁盘分区

磁盘分区是指将物理磁盘划分为多个逻辑存储单元的过程，这些单元被称为分区或卷。分区是物理磁盘的一个逻辑部分，它像一个独立的物理磁盘一样工作，具有自己的文件系统、存储容量和驱动器字母或挂载点。分区可以用于分离数据或操作系统，并通过允许在单个物理磁盘上使用多个文件系统来更高效地管理存储。常见的分区方案包括 MBR（主引导记录）和 GPT（GUID 分区表）。

## DNS

DNS 是 Domain Name System（域名系统）的缩写，它是一个将域名转换为 IP 地址的系统。DNS 用于通过人类可读的域名在互联网上定位网站。

## 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://docs.console.zenlayer.com/welcome/cn/glossary/a-g/d.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.
