Git & GitHub | 버전 관리 시스템 | 초기 설정

프로젝트 호스팅 사이트

GitHub 

-무료 호스팅 공간을 제공

 

version control, Source control

-데이터의 과거와 현재 상태 관리하는 것.

-복수의 사람들이 사횽하는 것임.

 

Git

-동시 다발적인 브랜치 작업.

-Git 만들기 시작한지 3일만 Git 자체의 버전 관리 시작함.

2주무렵 처음으로 복수의 브렌치를 한번에 병합하기 시작하면서 완성됨.

-대중성 안전성 검증됨

-돈이걸린,프로로서 일하는 개발자, 디자이너와 협업

 

VCS

-Version Control System
