Yuav ua li cas yog ib tug computer thiab nws yog dab tsi tam sim no

Thaum muaj cov thawj computer, tsis muaj ib tug tiag tiag yuav tsis hais. Tus txiv neej yeej ib txwm nrhiav kom piv thiab leeb tus txheej txheem ntawm suav, tsis paub txog dab tsi tau ua ib tug niaj hnub lub computer. Wealth pab pawg neeg loj hlob, thiab cov ntiv tes tau txaus rau suav. Nyob rau hauv lub chav kawm mus pob zeb thiab nrog, uas yuav muaj originated thawj zaug kev ua lej, decimal suav system. Nws coj ib co sij hawm, thiab nqa ib tug xov tooj ntawm lub pob zeb thiab sticks cia li los ua tsis xis nyob. Cov lo lus nug sawv nyob rau hauv kev txhim kho ntawm xam, thiab tejzaum nws originated "xav" nyob rau lub tsev lag luam ntawm suav machine. Puzzled ancient txiv neej tshaj cov qauv ntawm cov xam profit thiab accounting ntawm cov khoom, tsiaj nyeg, tais diav.

Yog li ntawd yog dab tsi yog ib tug computer? Ntawm cov hoob kawm, nws yog tsim nyog los tawm lub niaj hnub lub computer thiab dhia dej ntxaum mus rau hauv zaj dab neeg thiab tseem xav txog dab tsi tshwm sim tawm ib lub computer nyob rau hauv ib qho kev era. Tom qab tag nrho, kaum xyoo tom qab ntawd, peb cov me nyuam tej zaum yuav hu ua qhov tseeb qauv ntawm "cov khoom muaj npe" laptop 2012 - "tswvyim" los yog "cov nqi kho mob." Los yog txawm ib yam dab tsi zuj zus.

Thawj xam mechanism yog suav hais tias yog "abacus", progenitor ntawm Lavxias teb sab account. Feem ntau, nws yog ib tug board nrog cov kab los yog grooves, uas tau tso lub pob zeb. Muaj cai tshwj xeeb uas tso cai rau yuav ua li cas cov lus teb nyob rau hauv tas li ntawd thiab sib rho, thiab tom qab ntawd, thiab ua lej khu.

Pab mus rau txoj kev loj hlob ntawm suav cov cav tov ua los ntawm Fabkis zaum Gerber (950-1003). Tab sis, tom qab lub thoob plaws loj heev ntawm tus zauv xov tooj system thiab tau ntawm cov khoom laij rau ib daim ntawm daim ntawv, "abacus" tau poob nws cov qub tseem ceeb.

Ib zaug ntxiv, rov qab mus rau lo lus nug ntawm yog dab tsi ib tug computer yog, "abacus" raws li ib yam dab tsi tsis zoo heev rau cov thawj lub computer. Tab sis tawm nws ib yam nkaus thiab, tsis txhob ntxuav li - tag nrho cov tib zaj dab neeg.

muab xam txheej txheem yuav ntau thiab ntau nyuaj. Tsim banking, raug automation yuav tsum tau, lub tswv yim ntawm kev tsim los ntawm cov cav tov yeej tsis sab laug lub minds ntawm tus txiv neej. Nyob ib ncig ntawm 1632 tus German paub txog Schickard sib sau thawj nyob rau hauv lub keeb kwm ntawm lub suav mechanism. Tsis ntev Blez Paskal tsim ib tug zoo dua lub tsheb, los ua ib tug ancestress ntawm ib tug ntxiv tshuab.

Ntawm no yog peb tuaj, tej zaum, los ntawm lub sij hawm thawj lub computer. Ntxiv tshuab nrees tsau rau saum rooj ntawm accounting npe thiab ntau yam hauv tsev, qhov chaw uas lawv muaj ib tug ntau yuav tau xav txog. Nws ua heev yooj yim. Thaum tau arithmometer tig hauv lub ob zog tig nyob rau hauv kaum tej paug nyob rau hauv lub zoo theem tsev. Muab thiab faib lub tsheb no tau "qhia" Vilgelm Leybnits, tus poj philosopher thiab mathematician, uas tau ib tug zoo pab rau txoj kev loj hlob ntawm science thiab fundamentals ntawm computer technology.

Tus thawj computer yuav kuj pom tau tias tsis yog ib tug mechanism rau laij ib tug ntos, yees ua nyob rau hauv 1804 los ntawm qhov Fabkis engineer Yauxej Mari Zhakkarom. Lub mechanism yog muaj peev xwm embroider complex qauv tsis muaj tib neeg kev cuam tshuam, los ntawm txoj kev tshwj xeeb programming ntawm punched cards (thawj preimage diskettes) uas xav cov ntaub ntawv kaw tseg.

Tab sis li cas yog ib tug computer, los yog tej kev yooj yim tsis nws yuav tsum tau tej zaum qhib rau noob neej Charlz Bebbidzh, lub computer los ua ke pib nyob rau hauv 1834. Vim yuav tsum rau cov neeg thiab miniaturization ntawm qhov chaw yog tsis progressing, vim hais tias lub tsev hais plaub ntawm lub xyoo pua puv 19 thiab tsuas yog technology nyob rau hauv txoj kev loj hlob theem. Nyob rau hauv tas li ntawd, Charles tag nrho cov sij hawm los mus ua kom cov kev hloov thiab kev txhim kho hais tias, tej zaum, thiab tiv thaiv tau nws los ntawm ua kom tiav nws creation. Nws yog dim los ntawm nws ncauj lus kom ntxaws drawings thiab ncauj lus kom ntxaws comments sau cia los ntawm nws co-neeg ua hauj lwm, Adoy Lavleys, uas ua rau nws tau muab ib tug haib impetus mus rau lub kev loj hlob ntawm computers.

Babbage computer muaj cov ntaub ntawv tswv yim ntaus ntawv, ib tug cia ntaus ntawv zoo li ib tug RAM, ib tug xam unit rau cov khoom muab xam tswj ntaus ntawv, ib tug ntaus ntawv rau outputting ib tug tshwm sim. Thiab feem ntau nthuav yog hais tias tag nrho cov downloaded cov kev pab cuam kom ua tau tej yam ua Babbage computer ua los ntawm thaum pib los mus xaus tsis muaj kev pab tib neeg thiab muab zaum kawg tshwm sim nyob rau hauv daim ntawv ntawm cov coded lus tshwj xeeb punch card. Ob peb cov kev pab cuam tau raug sau los ntawm Ada programming kev tshawb xav tau yug los.

Ib tug niaj hnub lub computer tau muab khaws cia tseg tag nrho cov yam ntawm cov loj Cheebtsam Babbage computer. Sai li sai tau raws li kev siv cov transistors thiab semiconductors infinitely ntau zog nws tsim tau thiab muab ib qho yooj yim mus use.

Yog li ntawd, lo lus teb rau lo lus nug "Yuav ua li cas yog ib tug computer?" seb puas tsimnyog tau ib tug enormous reservoir ntawm cov keeb kwm cov txheej xwm thiab kev siv technology tshiab nrhav uas tau hloov zuj zuj los ntawm hiav txwv pebbles los superconductors.
