# 질문 사항

#### 1. 쿠키, 로컬 스토리지, 세션이란 무엇인가?

#### 2. RESTFUL API란?

REST란 **RE**presentational **S**tate **T**ransfer의 약자이다. connection-less, state-less한 HTTP 특성을 극복하기 위해, 클라이언트와 서버가 데이터를 주고 받을 때 상태를 표시하여 맥락을 이해할 수 있도록 고안된 API 포맷이다.

* 클라이언트

클라이언트는 서버의 리소스를 명시적으로 읽고 쓰기 위해, 요청 시 GET, POST, PUT, PATCH, DELETE 등 메소드를 붙여 어떤 액션(Action)임을 명시한다.

* 서버

서버에서는 클라이언트 요청을 핸들링하고, 처리 결과가 어떤 상태임을 Indicate(명시) 해주기 위해 Status 코드를 붙여 응답한다.

#### 3. HTTP란?

하이퍼텍스트 전송 프로토콜 (HTTP)는 분산, 협업, 하이퍼텍스트 정보 시스템에 대한 상태 없는 애플리케이션-레벨의 프로토콜이다.

## 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://hochan049.gitbook.io/cs-interview/web/undefined.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.
