ASCII is
een afkorting van American Standard Code for Information
Interchange en is een standaard om een aantal letters
en leestekens te representeren en aan ieder elemenet
in die reeks een binair geheel getal te koppelen, waarmee
dat leesteken of die letter wordt aangeduid.
ASCII is een 7-bits code, zodat er 128 ASCII tekens
zijn.
De meeste computers werken met 8-bit codes. Het 8e bit
werd traditioneel gebruikt voor foutdetecterende codes
en andere apparaatspecifieke toepassingen.
Omdat in landen buiten Amerika behoefte was aan extra
tekens is hiervoor later het 8e bit gebruikt.
Zo zijn extended ASCII tekenverzamelingen ontstaan die
maximaal 256 tekens coderen.
Hierbij zijn echter verschillen ontstaan tussen LANDEN
en ALFABETTEN.
ASCII is niet ?n bepaalde standaard, maar een verzamelnaam
voor de verschillende tekenrepresentaties die de eerste
128 ASCII tekens als basis hebben.
De eerste 32 tekens zijn voor een aantal meta tekens
gereserveerd, zoals einde regel bij... (of in sommige
alfabetten voor figuren)
Vanaf 32 beginnen de echte letters en leestekens.
Waarom ASCII gebruiken?
Omdat er in sommige gevallen tekens zijn die niet op
het klavier weergegeven worden en die afhankelijk van
de gebruiker toch wel handig kunnen zijn in gebruik.
Zoals bijvoorbeeld :
? of ?of ? of ? ←
→ ♂ ♀
