Hello World!

Build usually means the entire process of getting a system ready for use.
빌드는 보통 사용할 준비가 된 시스템으로 만드는 프로세스 전체를 뜻한다.

Compile is usually an action on a single file or group of files. The output of a compile step might be an executable or an object file or even a library of some sort.
컴파일은 한 파일 또는 파일 그룹을 대상으로 행해진다. 컴파일의 산출물은 보통 실행파일이나 오브젝트 파일 또는 어떤 라이브러리가 될 수도 있다.

Sometimes there is another step after build, to prepare a system for distribution.
때때로 배포를 위한 시스템을 준비하기 위해 빌드 이후에 다른 단계가 있기도 하다.
