Emuva Kokwedlule: I-DRAM kanye neFord Quadricycle (4/6/2020)

Phakathi kwezinye izinto, umhlaba wezobuchwepheshe uhlanganisa nemboni yezimoto. Namuhla kuphawula ukuhlolwa kokuqala kweFord Quadricycle, ehambisana nenkinga eyodwa ebabazekayo. Ngokungeziwe kulolu hambo, engxenyeni yanamuhla yochungechunge lwethu lomlando, sizophinda sikhumbule ilungelo lobunikazi lenkumbulo ye-DRAM noma ukugibela isitimela esisheshayo.

I-Ford Quadricycle test drive (1869)

NgoJuni 4, 1896, uHenry Ford wanquma ukuhlola imoto yakhe eyayisanda kuqedwa esebenzisa uphethiloli ebizwa ngokuthi iFord Quadricycle. Ekuqaleni, bekubukeka sengathi umnyango wegalaji, obonakale ubanzi ngokwanele, uzovimbela ukuhlolwa kwawo kokuqala okuyimpumelelo. Ngenhlanhla, le nkinga yaxazululwa ngosizo lwezinguquko zokwakha ezithuthukisiwe ezisheshayo. Amasango anwetshiwe futhi abakwaFord bakwazi ukuhlola ngempumelelo umkhiqizo wabo wakamuva. IFord Quadricycle inikeze amajubane amabili ahlukene, kodwa awekho ahlehlayo.

Ilungelo lobunikazi le-DRAM (1968)

Ngomhla zizi-4 kuJuni, 1968, uDkt. Robert Dennard we-IBM TJ Watson Research Center ugunyaze uhlobo lwenkumbulo yekhompyutha ye-DRAM (Dynamic Random Access Memory). I-DRAM igcina idatha ngendlela yokushaja kagesi ku-capacitor, ehambisana ne-parasitic capacitance ye-electrode yokulawula (Isango) yohlobo lwe-MOSFET transistor. Kungekudala ngemuva kokuthi uDennard enikezwe leli lungelo lobunikazi, i-Intel yakha chip yayo ephumelele kakhulu engu-1kb DRAM.
