推荐答案

记忆化是一种特殊的缓存形式，涉及根据功能的参数缓存功能的返回值 >。

Memoization is a specific form of caching that involves caching the return value of a function based on its parameters.

缓存是一个更笼统的术语；例如，HTTP缓存是缓存，而不是备忘录。

Caching is a more general term; for example, HTTP caching is caching but not memoization.

Wikipedia 说：

Wikipedia says:

虽然与缓存有关，但是记忆是指此优化的特定情况，将其与缓存，例如缓冲或页面替换。

Although related to caching, memoization refers to a specific case of this optimization, distinguishing it from forms of caching such as buffering or page replacement.
