The X3.2 subcommittee designed ASCII based on the earlier teleprinter encoding systems. Like other character encodings, ASCII specifies a correspondence between digital bit patterns and character symbols (i.e. graphemes and control characters). This allows digital devices to communicate with each other and to process, store, and communicate character-oriented information such as written language. Before ASCII was developed, the encodings in use included 26 alphabetic characters, 10 numerical digits, and from 11 to 25 special graphic symbols. To include all these, and control characters compatible with the Comité Consultatif International Téléphonique et Télégraphique (CCITT) International Telegraph Alphabet No. 2 (ITA2) standard, Fieldata, and early EBCDIC, more than 64 codes were required for ASCII.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): How many graphic symbols were used before ASCII?
11 to 25 special graphic symbols
X3.2-underkommittén konstruerade ASCII baserat på de tidigare teleprinterkodningssystemen. Liksom andra teckenkodningar specificerar ASCII en överensstämmelse mellan digitala bitmönster och teckensymboler (d.v.s. Grafemes och kontrolltecken). Detta gör det möjligt för digitala enheter att kommunicera med varandra och att bearbeta, lagra och kommunicera teckenorienterad information såsom skriftspråk. Innan ASCII utvecklades omfattade kodningarna i bruk 26 alfabetiska tecken, 10 numeriska siffror, och från 11 till 25 speciella grafiska symboler. Att inkludera alla dessa, och kontroll tecken som är kompatibla med Comité Consultativef International Téléphonique et Télégraphique (CCITT) International Telegraph Alphabet No. 2 (ITA2) standard, Fieldata, och tidig EBCDIC, krävdes mer än 64 koder för ASCII. Finns det ett svar på denna fråga (Om den inte kan besvaras, säg "osvarbar"): Hur många grafiska symboler användes före ASCII?
