Amaya Toman Nangaphambi kokuba iwashi elihlakaniphile le-Apple libone ukukhanya kosuku, abasebenzisi bebekwazi ukubophela ikhompuyutha esihlakaleni sabo ngendlela yedivayisi ebizwa ngeSeiko's OnHand PC. Yilokhu kanye esizokucabanga engxenyeni yanamuhla yochungechunge lwethu emlandweni wezobuchwepheshe, kodwa futhi sizokhuluma ngezakhiwo zika-von Neumann.
Kungaba njalo okuthakaselayo
Ikhompyutha yokuqala yesandla (1998)
Ngomhla ziyi-10 kuNhlangulana 1998, uSeiko wethula iwashi lokuqala emhlabeni eligqokwayo "PC". Idivayisi yathengiswa ngaphansi kwegama elithi OnHand PC (Ruputer), yayifakwe iphrosesa engu-3,6-bit 2MHz futhi ifakwe isitoreji esingu-102MP. Lonke ulwazi lwaboniswa kusibonisi se-LCD se-monochrome esinokulungiswa kwamaphikseli angu-64 x 285, iwashi lalinamandla okulanda izithombe, ukudlala imidlalo, futhi lalifakwe nezinhlelo ezintathu zokusebenza. Iwashi lalinohlelo lokusebenza lwe-W-Ps-DOS, idivayisi yayilawulwa izinkinobho ezintathu kanye nenduku yokudlala encane. Ukuvumelanisa kwe-OnHand PC nekhompyutha kwenzeke ngosizo lwembobo ye-infrared kanye nezingxenyekazi zekhompuyutha ezikhethekile nesofthiwe. I-OnHand PC iphinde yathengiswa ngo-$XNUMX.
Ikhompyutha kaVon Neumann (1946)
Ngomhla ziyi-10 kuNhlangulana 1946, ososayensi base-Princeton Institute Institute for Advanced Study (IAS) baphothula ngempumelelo ukwakhiwa kwekhompyutha kaJohn von Neumann. Ikhompyutha ibiqukethe inkumbulo yokusebenza, iyunithi ye-arithmetic-logic, isilawuli namadivayisi we-I/O. Ukucutshungulwa kweziyalezo zomuntu ngamunye kumemori kwenzeke ngeyunithi yokulawula, okokufaka nokuphumayo kwedatha kwanikezwa amayunithi okokufaka nokukhiphayo. Kokubizwa nge-architecture ye-von Neumann, idatha nemiyalo kuvezwe ngokunambambili futhi kwagcinwa enkumbulweni ezindaweni ezikhethwe ngamakheli. Uhlelo lukaVon Neumann lusasebenza ezimweni eziningi namuhla. Ikhompiyutha yayincane uma kuqhathaniswa nezindinganiso zangaleso sikhathi - yayilinganisa ngaphansi kwamamitha amabili ubude, cishe amamitha angu-2,4 ukuphakama futhi ingaphezudlwana kwamamitha angu-0,5 ububanzi.
Eminye imicimbi ayiveli emhlabeni wezobuchwepheshe kuphela
- Isixhumanisi sokuqala sekhebula le-intercontinental undersea sasebenza phakathi kweCanada ne-Ireland (izinsuku ezingama-26 kuphela (1858)
- I-IBM kanye ne-Microsoft basayina isivumelwano sokuthuthukisa isikhathi eside (1985)
- I-Microsoft imemezela izinhlelo zokuqeda ukusatshalaliswa kwe-MS Money (2009)
