Amaya Toman Engxenyeni yanamuhla yekholomu yethu evamile, lapho sibonisa khona izehlakalo ezibalulekile emlandweni wobuchwepheshe, sikhumbula ukwethulwa kwephrosesa engu-286 evela ku-workshop ye-Intel. Ngeshwa, ingxenye yesibili yesiqephu sanamuhla ngeke isajabulisa kakhulu - kuyo sikhumbula ukuphahlazeka okudabukisayo kwe-shuttle Columbia ngo-2003.
Kungaba njalo okuthakaselayo
Iprosesa ye-Intel 286 (1982)
NgoFebhuwari 1, 1982, i-Intel yethula iphrosesa yayo entsha engu-286 igama layo eliphelele laliyi-Intel 80286 (ngezinye izikhathi ibizwa nge-iAPX 286). Bekuyi-microprocessor engu-16-bit esekelwe ekwakhiweni kwe-x86, egijima ku-6MHz naku-8MHz, futhi okuhlukile okungu-12,5MHz kwethulwa kamuva nje. Amakhompiyutha omuntu e-IBM PC, kodwa nemishini evela kwabanye abakhiqizi, yayivame ukuhlonyiswa ngale processor. Iphrosesa ye-Intel 286 yayisetshenziswa kumakhompyutha womuntu kuze kube sekuqaleni kwawo-286. Ukukhiqizwa kwephrosesa ye-Intel 1991 yayekwa ngo-80386, futhi iphrosesa ye-Intel XNUMX yaba umlandeli wayo.
I-Space Shuttle Columbia Crash (2003)
Ngo-February 1, 2003, isithuthuthu sase-Columbia saphahlazeka kabuhlungu ekupheleni kwemishini ye-STS-107. Ingozi yenzeke ngesikhathi kubuyiswa - esikhathini esingaphezudlwana kwekota yehora ngaphambi kokufika endaweni ephephile. Ukuhlakazeka kwe-shuttle kwenzeka endaweni ephakeme ngamakhilomitha angu-63 ngaphezu kwendawo yesifunda saseTexas, Columbia yayihamba ngesivinini esingama-5,5 km / s ngaleso sikhathi, akekho noyedwa kumalungu ayisikhombisa okusinda engozini, imfucumfucu ye-shuttle yandizela endaweni yezifunda ezintathu zaseMelika. Izakhi zesistimu yokuhlenga zazihilelekile ekufuneni izinsalela zamalungu ezisebenzi kanye nemfucumfucu ye-shuttle, ukuhlanganiswa kwesenzo kwenziwa ngusonkanyezi u-James Donald Wetherbee. Ngesikhathi kuthungathwa udoti, indiza enophephela emhlane iBell 407 yashayisa ihlathi e-East Texas ekupheleni kukaMashi, kwashona ababili babasebenzi bayo.
