ASCII - American Standard Code for Information Interchange

ASCII ist eine Zeichenkodierung, die jedem Zeichen eine eindeutige Zahl zuordnet. Sie umfasst 128 Zeichen und verwendet dafür 7 Bit.

Aufbau

Bereich Inhalt
0–31 Steuerzeichen (z. B. Zeilenumbruch, Tab)
32–47 Satzzeichen und Sonderzeichen
48–57 Ziffern 0–9
65–90 Großbuchstaben A–Z
97–122 Kleinbuchstaben a–z

Beispiel

  • "A" → Dezimal: 65 → Binär: 01000001
  • "a" → Dezimal: 97 → Binär: 01100001
  • "5" → Dezimal: 53 → Binär: 00110101

Eigenschaften

  • 7-Bit-Kodierung (1 Byte, oberstes Bit = 0)
  • kompatibel mit vielen Protokollen und Dateiformaten
  • Grundlage für moderne Kodierungen wie UTF-8

Einschränkungen

  • nur 128 Zeichen
  • keine Umlaute, keine Akzente
  • keine internationalen Schriftzeichen
