아 순서 뒤죽 박죽인데 귀찮으니까 Pass

 

FAT = FILE ALLOCATION  TABLE

파일의 위치를 나타내는 표

하드디스크를 요롷게 저롷게 잘랐을 때 그거의 위치 !

0~42억 -> 32  비트 4G까지

 

 디스크 0라는 의미 만져지는 것 (물리 드라이브) c -> (논리 드라이브) -> 파티션으로 나누어져 있다. 

boot 은 윈도우도 연결 가능 리눅스도 연결가능 ! 

 

 

 

 

여기 까진 정상

raspberrypi.local

거꾸로 읽기 업로드할때 분명히 거꾸러 선택했는데 내가 멍청한건가 컴퓨터가 무조건 순서 나열인가 

 

미치겠네 계속 거꾸로 

 

 

 

 

 

 

 

리눅스 명령어 공부

 mkdir 이름/ -> 다이렉토리 만들기

 rmdir 이름/  -> 다이렉토리 지우기

$ -> 의미 일반 사용자 

# -> 관리자

sudo ->교대해서 멀하다

 

su root - > 관리자 모드로 변경

관리자는 비밀번호 안물어봄 !

pi@raspberrypi:~ $ su root
Password:

su- -> 당연히 관리자인줄 안다

 

바로 페스워드 물어본다

 

ctrl + d -> 로그 아웃

 

 

cd h +tab tab - > cd home/ 자동 완성기능 작동

 

 

pwd 절대 경로

 

어디있던 간에 cd로 치면 home 디렉토리로 돌아간다
