ASCII Code

ASCII(American Standard Code for Information Interchange)Code는 미국 표준협회(ANSI)에서 제시한 문자표시 체계로ASCII는 각 문자를 7비트로 표현하므로 총 128(= 2⁷)개의 문자를 표현할 수 있다.

ASCII로 표현할 수 있는 문자들 외에 추가적인 문자를 지원해야 할 필요성이 있어 기존 7비트에 1비트를 추가하여 8비트를 사용한 코드가 정의되었는데, 이를 확장(extended) ASCII라 하는데, 256(= 2⁸)개의 문자를 표현할 수 있다.

기존 7비트 ASCII 코드에는 가장 왼쪽에 0을 추가하여 8비트 형식이 되게 했다.

현재 ASCII Code가 일반적으로 사용되고 있다.
