# VonNeumannArchitecture

* 근대 컴퓨터는 연산과 제어를 위해 [중앙처리장치(Central Processing Unit, CPU)](broken://pages/39a4adb593184a38fe58a32ce1861773491ba78a), 저장을 위해 [기억장치(Memory)](broken://pages/67b999a8b99f511c4040b4b186a9c56bfdaa65f1)를 사용한다.
* 장치 간 데이터나 제어 신호를 교환할 수 있도록 [버스(Bus)](broken://pages/802399cd56e4ba69e5a44cdc99e3749c5d192851)라는 전자 통로를 사용한다.

{% hint style="info" %}
CPU안에 다른 저장장치가 왜 필요한가

CPU의 빠른 연산속도로 인해 주기억장치 또는 보조기억장치만 사용해서는 병목현상이 발생하게 된다.\
따라서 CPU는 데이터를 교환속도를 단축시키기 위해 "캐시"라는 저장장치를 내부에 갖게 되었다.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://krjaeh0.gitbook.io/j-log/programming/cs_basics/architecture/vonneumannarchitecture.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
