深入理解二进制文件(In-depth understanding of binary files)

 我正在学习C ++，特别是关于二进制文件结构/操作，因为我对二进制文件，位，咬和十六进制数的主题完全不熟悉，所以我决定向后退一步，对主题建立一个扎实的理解。 
 
 在下面我已经包含的图片中，我在.txt文件中写了两个单词（ blue thief ）。 
 
 
 原因是，当我使用hexeditor解码文件时，我想了解信息是如何以十六进制格式存储的。 现在，不要误解我的意思，我并不是试图通过整天阅读十六进制格式来谋生，而只是对二进制文件组合的基本知识有最低限度的理解。 我也知道所有文件都有不同的结构，但只是为了理解，我想知道，“蓝贼”和单个' ' （空格）这些词是如何被转换成这些字符的。 
 
 还有一件事是，我听说二进制文件包含三种类型的信息： 
 
 header ， ftm ＆和data ！ 那只关注音频，视频等多媒体文件吗？ 因为，除了它看起来只是这个文件中的data块之外，我似乎看不到任何东西。 

I am learning C++ specially about binary file structure/manipulation, and since I am totally new to the subject of binary files, bits, bites & hexadecimal numbers, I decided to take one step backward and establish a solid understanding on the subjects. 
 
In the picture I have included below, I wrote two words (blue thief) in a .txt file. 
 
 
The reason for this, is when I decode the file using a hexeditor, I wanted to understand how the information is really stored in hex format. Now, don't get me wrong, I am not trying to make a living out of reading hex formats all day, but only to have a minimum level of understanding the basics of a binary file's composition. I also, know all files have different structures, but just for the sake of understanding, I wanted to know, how exactly the words "blue thief" and a single ' ' (space) were converted into those characters. 
 
One more thing, is that, I have heard that binary files contain three types of information: 
 
header, ftm & and the data! is that only concerned with multimedia files like audios, videos? because, I can't seem to see anything, other than what it looks like a the data chunk in this file only.
