[[ASCII]] steht für '''American Standard Code for Information Interchange''' (ISO 646). ASCII ist eine 7 Bit Zeichenkodierung und bietet die Grundlage für spätere Zeichensatzkodierungen. Auf Grund der geringen Größe der Kodierung können lediglich 128 Zeichen in ASCII kodiert werden. Die Zeichenkodierung besteht aus 95 druckbaren und 33 nicht-druckbaren Zeichen (Steuerzeichen).
[[ASCII]] steht für '''American Standard Code for Information Interchange''' (ISO 646). ASCII ist eine 7 Bit Zeichenkodierung und bietet die Grundlage für spätere Zeichensatzkodierungen. Auf Grund der geringen Größe der Kodierung können lediglich 128 Zeichen in ASCII kodiert werden. Die Zeichenkodierung besteht aus 95 druckbaren und 33 nicht-druckbaren Zeichen (Steuerzeichen).


Die druckbaren ASCII-Zeichen sind:
Da sich unter den Zeichen keine Umlaute finden lassen, wurde der ASCII-Zeichensatz ISO 646-DE eingeführt, der beispielsweise die eckige Klammer ] auf das Ü abgebildet hat. Da jeweils nur ein Zeichensatz verwendet werden kann, wurde ASCII um ein weiteres Bit erweitert und bildet so die Grundlage für den für lange Zeit weltweit am häufigsten benutzten Zeichensatz, Codepage 437, für den (fälschlicherweise) oft auch das Synonym ASCII verwendet wird. In diesem Zeichensatz befinden sich 256 Zeichen, die reinen Text in vielen westlichen Sprachen darstellen können.
{|
 
:<big><code>␣!"#$%&amp;'()*+,-./0123456789:;<=>?</code></big>
Der Zeichensatz von Codepage 437 umfasst die folgenden Zeichen:
:<big><code>@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_</code></big>
 
:<big><code>`abcdefghijklmnopqrstuvwxyz{|}~</code></big>

Da sich unter den Zeichen keine Umlaute finden lassen, wurde der ASCII-Zeichensatz ISO 646-DE eingeführt, der beispielsweise die eckige Klammer ] auf das Ü abgebildet hat. Da jeweils nur ein Zeichensatz verwendet werden kann, wurde ASCII um ein weiteres Bit erweitert und bildet so die Grundlage für den für lange Zeit weltweit am häufigsten benutzten Zeichensatz, Codepage 437, für den (fälschlicherweise) oft auch das Synonym ASCII verwendet wird. In diesem Zeichensatz befinden sich 256 Zeichen, die reinen Text in vielen westlichen Sprachen darstellen können.


Inzwischen werden am häufigsten die 8 Bit großen Zeichensätze ISO 8859 oder UTF-8 verwendet.

ASCII steht für American Standard Code for Information Interchange (ISO 646). ASCII ist eine 7 Bit Zeichenkodierung und bietet die Grundlage für spätere Zeichensatzkodierungen. Auf Grund der geringen Größe der Kodierung können lediglich 128 Zeichen in ASCII kodiert werden. Die Zeichenkodierung besteht aus 95 druckbaren und 33 nicht-druckbaren Zeichen (Steuerzeichen).

Da sich unter den Zeichen keine Umlaute finden lassen, wurde der ASCII-Zeichensatz ISO 646-DE eingeführt, der beispielsweise die eckige Klammer ] auf das Ü abgebildet hat. Da jeweils nur ein Zeichensatz verwendet werden kann, wurde ASCII um ein weiteres Bit erweitert und bildet so die Grundlage für den für lange Zeit weltweit am häufigsten benutzten Zeichensatz, Codepage 437, für den (fälschlicherweise) oft auch das Synonym ASCII verwendet wird. In diesem Zeichensatz befinden sich 256 Zeichen, die reinen Text in vielen westlichen Sprachen darstellen können.

Der Zeichensatz von Codepage 437 umfasst die folgenden Zeichen:
