Kunamathuluzi ahlukahlukene asetshenziselwa imininingwane ye-alphanumeric ehambisa le misebenzi, yingakho le ndatshana izochaza:Yini i-Spreadsheet?.
Ithuluzi elisetshenziselwa imisebenzi ehlukene yezibalo nezokuphatha
Yini iSpredishithi?
Ispredishithi siqukethe ithuluzi elisetshenziselwa izinhlelo zezibalo nobudlelwano balo nokulandelana okunengqondo, yingakho libonakala ngokusiza ekusebenzeni kwe-alphanumeric ngezinga eliphezulu lokusebenza kahle. Kususelwa embhalweni we-elekthronikhi ukufaka imininingwane nezinombolo, ngakho-ke kulezi zinsuku zisetshenziselwa kabanzi imisebenzi ehlukile nokusebenza.
Siqukethe isipredishithi esenziwe ngamakholomu nemigqa lapho imininingwane ye-alphanumeric ifakwa khona njengoba kungenzeka, ngamaseli kungenzeka ukuhlela inani elikhulu lemininingwane nokuhlanganisa izinhlobo ezahlukahlukene zolwazi ukuze zibe nomphumela othile ngokusebenzisa izibalo nokusebenza okwenziwe yilesi sipredishithi, ukuze ukwazi ukusebenzisa izinhlobo ezahlukahlukene zezibalo zezibalo.
Ukusizakala ngokusebenza kanye nezici zalo mbhalo, kubalulekile ukwazi ukuthi iyini ispredishithi, ukuze ukuqonda izakhiwo zayo kwenze kube lula ukuyisebenzisa nokuqonda ukuthi ingasetshenziswa kanjani. Inikela ngezicelo ezahlukahlukene, ngoba ihlotshaniswa nezinhlobo ezahlukahlukene zemisebenzi ehlanganisa indawo yesayensi, ukubalwa kwezimali, izibalo noma endaweni yokuphatha.
Inekhono lokwenza imisebenzi ezenzakalelayo ngasikhathi sinye lapho iyala khona idatha ngokuya ngokucushwa okwenzelwe ispredishithi, inenzuzo yokuzivumelanisa nesimo noma imininingwane ethulwa kuspredishithi, ngokuvamile leli thuluzi isetshenziswa ezitholakala kumasevisi ahlukahlukene njenge-Openoffice, iMicrosoft Office, neLibreOffice, phakathi kokunye.
Uma ufuna ukwazi uhlelo lokuvikela ikhompyutha, kuyanconywa ukuthi ubone i-athikili ikuyo Kuyini isicishamlilo?, lapho kuchazwa khona ukubaluleka nokusebenza kwayo.
historia
Ukuqonda ukuthi ispredishithi siyini, kulula ukuba nolwazi ekudalweni kwayo, okwakungo-1972 ukuze kusetshenziswe ama-algorithm wesistimu ukwenza lula ukubalwa kwezokuphatha nokunengqondo ngendlela ephumelelayo. Yenziwe nguDan Bricklin kepha yayinelungelo lobunikazi nguPardo noLandau ngo-1970, ngakho-ke kukhona ukulandelana kokudalwa kwayo ngokuthuthuka kobuchwepheshe bekhompyutha.
Ngenxa yokudalwa kwayo, kwasungulwa indlela yokusebenzisa amathuluzi we-elekthronikhi wemisebenzi ehlukene kepha ngendlela elula, ukunciphisa umsebenzi wokusebenza okunengqondo nokwezibalo okwethulwa ngaleso sikhathi. Ngenxa yalokhu, intuthuko yaphakanyiswa endaweni yezentengiselwano, ngoba yayisetshenziswa izinkampani namabhizinisi ukugcina ukuhleleka nokuphathwa kwemikhiqizo ekhiqizwayo.
Uma ufuna ukwazi ngeminye imiboniso yentuthuko yezobuchwepheshe, uyamenywa ukuthi ufunde indatshana ngu Izibonelo zobuchwepheshe bedijithali, lapho kuchazwa khona incazelo nezibonelo zayo eziyinhloko.
Ukusebenza
Ngemuva kokuqonda ukuthi ispredishithi siyini kanye nomlando waso, kuyadingeka ukuqonda ukuthi ispredishithi se-elekthronikhi senzani, ngoba namuhla kunezinhlobonhlobo zezicelo, ngakho-ke ayisetshenziswa kuphela endaweni yezohwebo noma yezokuphatha. ngenxa yentuthuko yezobuchwepheshe elethe imisebenzi emisha ohlelweni lwakho ngezinzuzo ezengeziwe.
Kungenzeka ukufaka idatha ehlukahlukene kuspredishithi ngokulandelana kokusebenza ukuze kusungulwe uhlu lokuhlela idatha ethile, ukuze igcinwe ohlelweni lwekhompyutha futhi iphrintwe uma kunesidingo. Ungafaka futhi amafomula ahlukahlukene ukuthola imiphumela nedatha efakwe esitokisini ngokulandelana okunengqondo nokusebenza.
Eminye yemisebenzi yayo iqukethe ukuhlanganisa uchungechunge lwedatha kwigrafu ukuze imiphumela ofuna ukuyazi ikhonjiswe futhi ibonwe; Ngakho-ke, kukhona nethuba lokwakha ishidi lokusebenzela elizenzakalelayo lapho imisebenzi ethile ingasetshenziswa khona uma kwenzeka imininingwane ephathelene nesihloko esithile njengezezimali zenkampani kufanele ikhonjiswe.
