# Endian-ness in FAT32

Endian-ness is about byte ordering. We have two types: **big endian** and **little endian**.

Suppose we see the following, which represents the bytes per sector.

![](/files/-Lp-5n4ZpJpAaB6XUFbC)

We have two ways to interpret this number, either *0x00 02* or *0x02 00*

## Big Endian <a href="#big-endian" id="big-endian"></a>

0x0002 = 2 bytes

## Little Endian <a href="#little-endian" id="little-endian"></a>

0x0200 = 512 bytes

As in FAT32, **little Endian** is used. Therefore, the number of bytes per sector is *512 bytes*.

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:

```
GET https://eric-lo.gitbook.io/lab9-filesystem/important-commands/viewing-with-hex-editor/endian-ness-in-fat32.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
