Xisaabiyaha sayniska casriga ah oo LCD ah

Xisaabiyaha elektarooniga ah sida caadiga ah waa aalad elegtaroonig ah oo la qaadi karo oo loo isticmaalo in lagu sameeyo xisaabinta, laga bilaabo xisaabinta aasaasiga ah ilaa xisaabta adag.

Xisaabiyaha-xaalada adag waxaa la sameeyay horraantii 1960-meeyadii. Aaladaha jeebabka le’eg ayaa la helay sannadihii 1970-meeyadii, gaar ahaan wixii ka dambeeya Intel 4004, Microprocessor-kii ugu horreeyay, waxaa u soo saartay Intel shirkadda xisaabiyaha Jabaanka, Busicom.

Xisaabiyeyaasha elektarooniga ah ee casriga ahi waxay ku kala duwan yihiin raqiis, wax-is-bixin-siin, moodooyinka cabbirka kaararka-credit-ka ilaa moodooyinka desktoob-ka adag ee leh madbacadaha ku dhex jira. Waxay caan noqdeen bartamihii 1970-meeyadii iyadoo isku darka wareegyada isku dhafan ay hoos u dhigtay cabbirkooda iyo kharashkooda. Dhammaadkii tobankaas sano, qiimuhu wuu hoos u dhacay ilaa heer xisaabiyaha aasaasiga ahi uu ahaado mid la awoodi karo inta badan waxayna noqdeen wax caadi ah dugsiyada.
