Amaya Toman Txawm hais tias ua ntej Apple lub smartwatch pom lub teeb ntawm hnub, cov neeg siv tuaj yeem khi lub computer rau lawv lub dab teg hauv daim ntawv ntawm cov cuab yeej hu ua Seiko's OnHand PC. Qhov no yog raws nraim li cas peb yuav xav txog niaj hnub no ib feem ntawm peb series ntawm keeb kwm ntawm technology, tab sis peb kuj yuav tham txog von Neumann lub architecture.
Nws yuav yog txaus siab rau koj
Thawj lub dab teg computer (1998)
Thaum Lub Rau Hli 10, 1998, Seiko tau tshaj tawm lub ntiaj teb thawj qhov hnav "PC watch". Cov cuab yeej raug muag raws li lub npe OnHand PC (Ruputer), tau nruab nrog kaum rau-ntsis 3,6MHz processor thiab nruab nrog 2MP cia. Tag nrho cov ntaub ntawv tau tshwm sim ntawm ib qho monochrome LCD zaub nrog kev daws teeb meem ntawm 102 x 64 pixels, lub moos muaj peev xwm rub tawm cov duab, ua si ua si, thiab kuj tau nruab nrog peb daim ntawv thov. Lub moos khiav ntawm W-Ps-DOS kev khiav haujlwm, lub cuab yeej tau tswj los ntawm peb lub nyees khawm thiab lub joystick me me. Synchronization ntawm OnHand PC nrog lub computer tau tshwm sim nrog kev pab los ntawm infrared chaw nres nkoj thiab tshwj xeeb kho vajtse thiab software. OnHand PC muag rau $ 285.
Von Neumann lub computer (1946)
Thaum Lub Rau Hli 10, 1946, cov kws tshawb fawb los ntawm Lub Tsev Haujlwm Princeton Institute for Advanced Study (IAS) tau ua tiav kev txhim kho ntawm John von Neumann lub computer. Lub khoos phis tawj muaj lub cim xeeb ua haujlwm, chav ntsuas lej-logic, tus tswj hwm thiab I / O cov khoom siv. Kev ua tiav ntawm tus kheej cov lus qhia hauv lub cim xeeb tau tshwm sim los ntawm chav tswj hwm, cov ntaub ntawv tawm tswv yim thiab cov khoom siv tau muab los ntawm cov tswv yim thiab cov khoom siv. Nyob rau hauv lub npe hu ua von Neumann architecture, cov ntaub ntawv thiab cov lus qhia tau qhia nyob rau hauv binary thiab khaws cia nyob rau hauv lub cim xeeb ntawm qhov chaw xaiv los ntawm chaw nyob. Von Neumann lub tswv yim tseem siv tau rau ntau qhov xwm txheej niaj hnub no. Lub khoos phis tawj kuj me me los ntawm cov qauv ntawm lub sijhawm - nws ntsuas tsawg dua ob metres ntev, txog 2,4 meters hauv qhov siab thiab tsuas yog tshaj 0,5 meters hauv qhov dav.
Lwm cov xwm txheej tsis yog los ntawm lub ntiaj teb ntawm kev siv tshuab xwb
- Thawj qhov kev sib txuas hauv qab hiav txwv hauv qab tau ua haujlwm ntawm Canada thiab Ireland (tsuas yog 26 hnub (1858))
- IBM thiab Microsoft kos npe rau daim ntawv cog lus kev loj hlob mus ntev (1985)
- Microsoft tshaj tawm cov phiaj xwm xaus kev faib tawm ntawm MS Money (2009)
