I keep seeing "bootstrapping" mentioned in discussions of application development. It seems both widespread and important, but I've yet to come across even a poor explanation of what bootstrapping actually is; rather, it seems as though everyone is just supposed to know what it means. I don't, though. Near as I can figure, it has something to do with initialization tasks required of an application upon launch, but I could be completely wrong about that. Can anyone help me to understand this idea?

“Bootstrapping”来源于“靠自己的力量把自己拉起来”这个词。这些你可以从维基百科上得到。
在计算中，引导加载程序是机器启动时运行的第一段代码，负责加载操作系统的其余部分。在现代计算机中，它存储在ROM中，但我记得PDP-11上的引导过程，你可以通过前面板开关插入位来将特定的磁盘段加载到内存中，然后运行它。不用说，引导加载程序通常非常小。
“Bootstrapping”也被用作一个术语，用于构建一个使用自身的系统——或者更准确地说，是一个前身版本。例如，ANTLR版本3使用在ANTLR版本2中开发的解析器编写。

问题已经回答了。用于网页开发。 到目前为止，我在Laravel文档中找到了一个关于引导的很好的解释。这是链接
一般来说，我们指的是注册事物，包括注册服务 容器绑定、事件监听器、中间件，甚至路由。
希望对学习web应用程序开发的人有所帮助。
为了完整起见，它也是统计学中一个相当重要的(相对较新的)方法，它使用重采样/模拟从样本中推断总体属性。它在维基百科上有一篇关于自我引导(统计)的长篇文章。
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.
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
etc.
