参见维基百科关于引导的文章。

有一个部分和链接解释了它在计算中的含义。它在这个领域有四种不同的用途。

这里有一些引用，但要更深入的解释和其他含义，请参考上面的链接。

＂...是一种技术，通过一种简单的计算机程序激活一个更复杂的程序系统。” “自举一词的另一种用法是使用编译器来编译自己，首先用现有语言编写一种新编程语言的编译器的一小部分，然后用新语言编写更多的新编译器程序。”

恕我冒昧，没有比第一个编译器是如何编写的更好的解释了?

现在，操作系统加载是最常见的过程，称为引导

As a humble beginner in the world of programming, and flicking through all the answers here after seeing this word used a lot in apparently slightly different ways in different places, I found reading the Wikipedia page on Bootstrapping (duh! I didn't think of it either at first) is very informative to understand differences in use of this word. Could it be......on extremely rare occasions......Wikipedia might even have better explanations of certain terms than....(redacted)? Will they bring in rep points on Wikipedia though?

对我来说，似乎所有的意义都与:从尽可能简单的东西开始，用Thing2做一些稍微复杂的东西，现在你可以用Thing2比原来的Thing1更有效、更快地完成某些任务。然后从第二件事重复到第三件事，直到无限……

I see it as closely connected to both biological evolution and 'Layers of Abstraction' (newbies like me see, ahem, Wikipedia, cough) - the evolution from 1940's computers with switches, machine code, Assembly, C, Python, AIs you can give all kinds of complex instructions to like "make the %4^% dinner to my default &^$% requirements and clean the floor you %$£"@:~" in drunken slang English or Amazon tribal dialect without them 'raising an exception' (for newbies again...you guessed it) - missed out lot of links there due to simple ignorance.

那么在某些特定的软件意义上: 含义1:Thing1用于加载Thing2的最新版本(因为Thing2当然会比Thing1大，就像Thing3会比Thing2大一样)。

Meaning2: Thing1 is a lower level language (closer to 1001011100....011001 than print("Hello, ", user.name)) used to write a little bit of the higher language of Thing2, then this little bit of Thing2 is used to expand Thing2 itself from baby vocabulary level towards adult vocabulary level (Thing2 starts to be processed, or to use correct technical term 'compiled', by the baby version of itself (it's a clever baby!), whereas the baby version of Thing2 itself could of course only be compiled by Thing1, cause it can't exist before it exists, right duh!), then child version of Thing2 compiles Surly Teenager version of Thing2, at which point programming community decides whether Surly Teenager's 'issues' (software term and metaphor term!) are worth spending enough time resolving to be accepted long term, or to abandon them to (not sure where to take the analogy here).

如果是，那么Thing2已经“bootstrap”自己(可能有几次)从婴儿到成年:“孩子是男人的父亲”(华兹华斯，建议不要试图在Stack Overflow上查找引用或作者)。

术语“自举”通常适用于系统依赖自身启动的情况，有点像鸡和蛋的问题。

例如:

如何编译用C编写的C编译器? 如果操作系统还没有运行，如何启动操作系统初始化进程? 如何启动一个分布式(点对点)系统，在这个系统中，客户端依赖于它们当前已知的对等点来查找系统中的新对等点?

在这种情况下，bootstrapping指的是一种打破循环依赖关系的方法，通常借助外部实体的帮助。

您可以使用另一个C编译器来编译(引导)您自己的编译器，然后您可以使用它来重新编译自己 您使用一段单独的代码来设置初始进程，而不依赖于操作系统提供的任何函数 您使用硬编码的初始对等体列表或提供对等体列表的硬编码跟踪器URL

I belong to the generation who flipped switches to enter a boot program. In the early 1980s, I worked on a microcomputer called Micro-78, developed by Electronics Corporation of India Ltd (ECIL). It was a sort of clone of Altair 8800. I distinctly remember what happens when a small boot program was entered using the toggle switches and executed by pressing a button. The program reads a second boot program contained in the 1st track of the floppy disk and overwrites it on itself in such a way that the second boot program starts executing to load a disk operating system. I think the term "bootstrap" refers to this process of the first boot program reading and overwriting the second boot program on itself, in a way "pulling itself up" with the additional functionality of the second boot program. That may be the origin of the original meaning of "the bootstrap program".

Boot strapping the dictionary meaning is to start up with minimum resources. In the Context of an OS the OS should be able to swiftly load once the Power On Self Test (POST) determines that its safe to wake up the CPU. The boot strap code will be run from the BIOS. BIOS is a small sized ROM. Generally it is a jump instruction to the set of instructions which will load the Operating system to the RAM. The destination of the Jump is the Boot sector in the Hard Disk. Once the bios program checks it is a valid Boot sector which contains the starting address of the stored OS, ie whether it is a valid MBR (Master Boot Record) or not. If its a valid MBR the OS will be copied to the memory (RAM)from there on the OS takes care of Memory and Process management.
