La table ASCII
ASCII : (American Standard Code for Information Interchange ) Norme d'encodage informatique des caractères alphanumériques de l'alphabet latin. La norme ASCII (on prononce généralement "aski") établit une correspondance entre une représentation binaire des caractères de l'alphabet latin et les symboles, les signes, qui constituent cet alphabet. Par exemple, le caractère "a" est associé à "01100001" et "A" à "01000001".
La norme ASCII permet ainsi à toutes sortes de machines de stocker, analyser et communiquer de l'information textuelle. En particulier, la quasi totalité des ordinateurs personnels et des stations de travail utilisent l'encodage ASCII.
Le codage ASCII est souvent complété par des correspondances supplémentaires afin de permettre l'encodage informatique d'autres caractères, comme les caractères accentués par exemple. Cette norme s'appelle ISO-8859 et se décline par exemple en ISO-8859-1 lorsqu'elle étend l'ASCII avec les caractères accentués d'Europe occidentale.
Il existe d'autres normes que l'ASCII, comme l'Unicode par exemple, qui présentent l'avantage de proposer une version unifiée des différents encodages de caractères complétant l'ASCII mais aussi de permettre l'encodage de caractères autres que ceux de l'alphabet latin. Le codage UTF8 de l'Unicode est une extension d'ASCII utilisant le 8e bit. (Source Dicodunet.com).
