如何补丁和服务包的工作？ [英] How do patches and service packs work?

问题描述

如何补丁或服务包的工作？我不知道该怎么解释我的问题，但我会给一个尝试

How do patches or service packs work? I don't know how to explain my question but I will give a try

以Windows为例。它具有完全消耗MB的100S文件。现在，一个服务包（可能是300 MB的文件）更新整个Windows操作系统。

Take Windows for example. It has files which altogether consume 100s of MB. Now a single service pack (may be 300 MB file) updates the whole windows OS.

同样地，我已经看到了发生的更新对于像Adobe阅读器等。在所有这些情况下，软件相比，更新的主要exe文件大得多。如何工作的过程？如果主文件引用的任何依赖关系文件，如果更新更改版本或大小。这不是要影响的EXE？

Similarly I have seen updates happening for softwares like adobe reader etc. In all these cases the main exe is much larger compared to the update. How does the process work? If the main file refers any dependancy files and if the update change the version or size. Will it not affect the exe?

推荐答案

补丁和服务包通常只需要更新系统的核心共享库。这些库被替换或从COM pressed存档补丁，因此它们的大小。一旦库更新OS的软件的其余部分可继续使用的新版本。

Patches and service packs usually only need to update core shared libraries of the system. These libraries are replaced or patched from a compressed archive, hence their size. Once the libraries are updated the rest of the software of the OS can continue using the new versions.

应用现今被设计为模块化的，使用可以很容易地更新外部库。有时使用不需要主应用程序或任何媒体被替换，只有已经改变库

Applications nowadays are designed to be modular and to use external libraries which can be updated easily. Sometimes the main application or any media used does not need to be replaced, only the library that's changed.
