Sasungulwa nini isibali?

Isibali sinomlando omude osukela ekhulwini le-XNUMX. Namuhla isetshenziswa ezimweni ezihlukahlukene, kusukela ehhovisi kuya ekilasini. Nakuba abantu abaningi becabanga ukuthi umshini wokubala wasungulwa kamuva nje, akunjalo.

Umsuka Wokubala

Ithuluzi lokuqala lokubala lakhiwa uBlaise Pascal, isazi sezibalo saseFrance esidumile sekhulu le-70. Umshini wakhe wawuklanyelwe ukwengeza nokukhipha, kodwa wawungenalo ikhono lokuphindaphinda noma ukuhlukanisa. Cishe eminyakeni engu-4 kamuva, esinye isazi sezibalo esingumFulentshi, u-Gottfried Leibniz, sasungula umshini wokubala ongcono kakhulu owawukwazi ukwenza wonke ama-opharetha ayisisekelo angu-150. Le divayisi yasetshenziswa iminyaka engu-XNUMX ngaphambi kokuba kudalwe umshini wokubala we-elekthronikhi wangempela.

Izibali zikagesi

Phakathi neminyaka yawo-1920, kwasungulwa izinto eziningi eziqanjiwe ezandulela umshini wokubala wesimanje. AMABHANGE asebenzisa imishini ukuze aphathe izimali zawo. Ngemva kwale mishini emisha kwavela izibali zokubala zikagesi zokuqala. Lawa madivaysi athengiswa ngentengo ephezulu futhi asebenzisa amandla amaningi ukwenza izibalo eziyinkimbinkimbi.

I-Pocket Calculator Yokuqala

Kwakuyi-pocket calculator eyagcina iholele ekudumeni kwala madivayisi. imishini yokubala ephaketheni yokuqala yaqala ukwenziwa ngo-1975. Lezi zibalo zokuqala zazingasetshenziswa ukwenza imisebenzi elula, njengokwengeza nokukhipha izinombolo. Njengoba isikhathi siqhubeka, amandla alawa madivaysi anda futhi nosayizi wawo wehla.

Intuthuko Yakamuva

Ama-Calculator adlule oguqukweni phakathi neminyaka. Namuhla, kungenzeka ukwenza imisebenzi ehlukahlukene usebenzisa umshini wokubala. Le misebenzi ihlanganisa ukwenza izibalo ze-algebraic, i-geometry, ne-trigonometry. Izibali zesimanje zivame ukuba nezibonisi ezimibalabala, izinkinobho ezisebenzisanayo, nezici ezihlukahlukene ezithuthukile. Futhi, kunezinhlobonhlobo zezinhlelo zokusebenza zeselula ezinikeza ukusebenza okufanayo.

Izinzuzo

Isibali singumsunguli omkhulu wesimanje osisize ngezindlela eziningi. Nazi ezinye zezinzuzo eziyinhloko zokusebenzisa umshini wokubala:

  • Isivinini: Izibali zishesha kakhulu kunezinye izindlela ezenziwa ngezandla ukwenza izibalo zezibalo ezihlukene.
  • Ukunemba: Izibali zinganikeza imiphumela enembe kakhulu kunemiphumela etholwe mathupha.
  • Kulula ukuyisebenzisa: Izibali ezintsha eziklanywe namuhla zinembile kakhulu futhi kulula ukuzisebenzisa, ngaphandle kokuthi umsebenzisi azi ingqondo yangaphakathi yezibalo ezenziwe.

Umnotho isikhathi: Ngokwenza izibalo ngokushesha nangokunembile, wonga isikhathi esiningi nomzamo. Lokhu kuvumela abasebenzisi ukuthi bonge isikhathi kuzo zonke izindawo.
Ukufinyeleleka: Kulula ukuthola isibali ku-inthanethi noma esitolo esiseduze. Lokhu kusho ukuthi asikho isidingo sokuthenga umshini wokubala we-elekthronikhi oyinkimbinkimbi ukuze wenze izibalo.

Sasungulwa nini isibali?

Isibali njengoba sisazi namuhla siyisisetshenziswa esiwusizo nesibalulekile kubantu abaningi. Kodwa ingabe wake wazibuza ukuthi umshini wokubala wasungulwa nini?

Umlando Wokubala

Umlando wokubala uqala kudala ngaphambi kwenkathi yesimanje. Emuva ngo-1623, isazi sezibalo esingumFulentshi, isazi sefiziksi, nesazi sezinkanyezi uBlaise Pascal waklama umshini wokuqala wokwengeza umshini. Lesi kube umshini wokubala wokuqala owaziwayo onesondo elilodwa elinamazinyo elisetshenziselwa ukuhlanganisa nokukhipha. Phakathi namakhulu eminyaka alandelayo, abanye abasunguli abanjengoLeibniz noHahn baba negalelo elikhulu ekuthuthukisweni kwemishini efanayo.

Izibali zokuqala ezisekelwe ekukhanyeni zaklanywa ngo-1902, zanikezwa ilungelo lobunikazi ngo-1924. Lezi zibali zokubala zakuqala zazikwazi ukwenza izibalo eziyisisekelo. Kodwa kwaba ngo-1945 kuphela lapho isazi sezibalo saseMelika uJohn Atanasoff sakha umshini wokubala we-elekthronikhi okwazi ukwenza ingqondo, ukubala kwe-algebraic, kanye nokubala komehluko.

Izibali Zesimanje

Phakathi neminyaka yawo-1970, umshini wokubala waqala ukuba ngcono. Izingxenye ze-elekthronikhi ezincane zivumela ama-pocket divayisi ukuthi adalwe. Namuhla, singathola ama-pocket calculator anezici ezihlukahlukene eziwusizo, njenge:

  • logic ehlelekayo
  • Memoria
  • ukusebenza kwe-algebraic
  • ihluzo ezisesikrinini

Ngakho-ke, singasho ukuthi ukuphakama komshini wokubala kuguqule inkambo yomlando. Lokhu kwenze kwaba lula kakhulu ukubala kwezibalo futhi kusivumele ukuthi senze izinqubo eziyinkimbinkimbi kakhulu kalula.

Okuqukethwe yi-athikili kuhambisana nemigomo yethu yezimiso zokuziphatha zokuhlela. Okwamanje sisebenzela ukulungisa nokuthuthukisa okuqukethwe kwethu ngezinye izilimi.

Uma ungumhumushi ogunyaziwe ungasibhalela nokusebenza nathi. (isiJalimane, iSpanishi, isiFulentshi)
