## 💫 정리 시 참고사항
* 깃허브 저장소에 정리되어 있는 주제들을 보고 참고해주세요.
* 각 주의 정리 순서는 `운영체제` → `네트워크` → `데이터베이스` → `자바 및 스프링` → `자유 주제` 순으로 진행됩니다.
* 내용 정리는 줄글이 아닌 **한눈에 파악하기 쉽도록 깔끔하게** 정리해주세요.
* br 태그를 이용하여 문단 간의 공백을 넣어주세요.
* Tech-Interview에 있는 질문들에 대한 답만 정리하는 것이 아닌, **개념 위주**로 정리해주세요.
* 질문들은 주제에 대한 키워드이기 때문에 정리해나갈 방향 정도로 생각해주세요.
* 커밋하기 전에 **동기화**를 꼭 해주세요.
## 💡 Rule
**\[ 스터디 진행 ]**
* 매주 수요일 20시 00분 화상스터디 진행
* 저번 주차의 주제들을 바탕으로 면접 준비
* 화상 스터디 전 날(화요일)까지 맡은 주제를 정리해서 PR 생성
**\[ 스터디 방법 ]**
* 매주 각 분야별로 하나씩 총 5개의 주제 선정
* 각자 해당 주차의 주제들 중 하나를 맡아 정리
* 저번 주차의 주제들 모두 학습 및 주제 별 질문리스트 생각해오기
**\[ 스터디 규칙 ]**
* 스터디 진행 시 항상 카메라 ON
* 특별한 사유없는 불참과 맡은 주제 정리 미완료 3회시 스터디 퇴장
* 사유가 있을 경우 사전 공지(최소 하루전)
