ENIAC . US Army cov ENIAC qhov project yog thawj lub computer rau muaj lub cim xeeb cia muaj peev xwm nyob rau hauv txhua daim ntawv. Ua ke nyob rau lub caij nplooj zeeg xyoo 1945, ENIAC yog lub pinnacle ntawm niaj hnub technology (zoo, tsawg kawg ntawm lub sij hawm). Nws yog 30 tuj dab, nrog thiry cais units, ntxiv rau lub hwj chim mov thiab yuam cua txias.

Hauv qhov no, thawj lub khoos phis tawj Eniac loj npaum li cas thiab nws muaj lub cim xeeb npaum li cas?

ENIAC tau loj heev. Nws muaj 17,500 lub tshuab nqus tsev vacuum, txuas los ntawm 500,000 soldered kev sib txuas. Nws puv 50-foot ntev hauv qab chav tsev thiab hnyav 30 tons. Niaj hnub no, ib lub microchip, tsis loj dua tus ntiv tes, tuaj yeem ua tau ntau tshaj li 30 tons ntawm cov khoom siv.

Yuav ua li cas muaj pes tsawg tus transistors Eniac computer muaj thaum nws tsim? Thaum kawg ntawm nws txoj haujlwm xyoo 1956, ENIAC muaj 20,000 lub tshuab nqus tsev vacuum; 7, 200 siv lead ua diodes; 1,500 relays; 70, 000 resistors; 10, 000 capacitors; thiab kwv yees li 5,000,000 tes-soldered pob qij txha.

Tsuas yog li ntawd, Eniac tau siv ntau qhov chaw?

1,800 m² os

Eniac hloov lub ntiaj teb no li cas?

ENIAC : Thawj lub computer ua keeb kwm. Cov ENIAC , los yog Electronic Numerical Integrator thiab Computer, tuaj yeem churn 5, 000 ntxiv teeb meem hauv ib thib ob, nrawm dua li txhua yam khoom siv tseem tau tsim. Thaum Lub Ob Hlis 1946, J. Ob peb xyoos, cov khoos phis tawj yuav tshwm sim hauv cov tsev kawm qib siab, tsoomfwv cov koomhaum, tsev txhab nyiaj thiab tuam txhab pov hwm.
