Raws li computer technology tau hloov zuj zuj

Cov qib kev loj hlob ntawm computer technology yuav tsum tau muab faib mus rau hauv rau sij hawm, nrog pes tsawg rau lub thib tsib tiam. Txhua yam ntawm lawv muaj xws li ib tug los yog lwm kauj ruam nyob rau hauv txoj kev loj hlob ntawm architecture thiab computer zog. Ob peb cov neeg paub hais tias cov thawj computer technology muaj nyob rau hauv lub thib kaum rau caug xyoo. Blaise Pascal yees ua ib tug cov neeg kho tshuab computer yuav ua xwb lub zog ntxiv thiab sib rho, tab sis nws muaj ib hom ntawm cov neeg kho tshuab ntsiab, zog thiab los ntawm txhais tes tsav. Ib me ntsis tom qab nws tau yees ua (rau peb centuries) mus rau ntau yam kev hloov kho, uas yuav ua lej khu, division, thiab txuag intermediate tau, tab sis nyob rau hauv kev computer technology ntawm lub sij hawm tsis muaj ntau tej chaw thiab tsis tau paub ntau tshaj qhov theem ntawm ib tug niaj hnub hnab tshos tswvyim. Qhov no lub sij hawm no yog hu ua lub voj tiam.

Tus thawj tiam

Kev loj hlob ntawm computer technology mus txog lub toj rau ntawm qhov pib ntawm ob ntiaj teb rog. Qhov no yog feem ntau vim cov tub rog xav tau kev pab, raws li German submarines tog thiaj li muaj ntau British ships xa mus rau txhua lwm yam thiab mus rau lub bank coded xov tooj cua. Thiab txawm ua tau outbid lub encoding ntaus ntawv (enigma), lub British to taub hais tias lub seev suab ntawm lub xov tooj cua yuav tsum tau yuav luag instantaneous, uas txhais tau tias koj yuav tau sai sai tsim zoo npaum li cas ntawm xam. Nws yog thaum lub sij hawm lub sij hawm no zoo nkaus li tus thawj hluav taws xob computer ntawm Colossus, uas, li cas los xij, tseem ib tug tub rog tsis pub leejtwg paub rau ntau tshaj peb caug xyoo.

Ib tug txawv feature ntawm cov thawj computers raws li nyob rau hauv qhov hluav taws xob yog siv nyob rau hauv lawv lub nruab raj processor nrog binary code cov tshuaj tiv thaiv ( "zero-theem", uas tau ua counterparts ntawm txhais zog "yeej muaj tseeb-tsis tseeb"), uas yog ib tug lossis loj kauj ruam rau pem hauv ntej.

ob tiam

Nyob rau hauv 1956, lub physicist tau yees ua lub thawj transistor, uas tau muaj peev xwm tsis tsuas hloov lub teeb Circuit Court obsolete computers, tab sis kuj yuav ua rau nws kaum lub sij hawm me me thiab me me! Nws yog nyob rau hauv no cov keeb kwm lub sij hawm twb thawj computers, uas hnub no yog hu ua supercomputers, thiab yog siv nyob rau hauv ntau yam hluav taws xob archives, cov tsev qiv ntawv thiab loj xav tank.

peb tiam

Los ntawm lub sij hawm ntawd nyob rau hauv computer technology tau hloov zuj zuj sai heev. Kaum xyoo tom qab ntawd, lub tshav pob ntawm zus tau tej cov thawj transistor computer yog invented, tau koom ua ke thiab muaj nyob rau hauv thawj kev Circuit Court zus tau tej cov computers, uas tso cai rau tus thawj computer manufacturers yuav tau xav txog yuav ua li cas mus pib ua tsev PCs.

plaub tiam

Integrated circuits yog zoo los ntawm tus kawg ntawm lub thib nees nkaum xyoo pua, muaj twb ntau yog hu mus rau lub chips vim lub sheer tooj ntawm transistors (mus txog tsheej lab!) Tias lawv yuav haum. VLSI - tias yog dab tsi hnub no stands lub tsev, txhua tus nyob rau hauv daim ntawv ntawm tus kheej computers. Nyob rau hauv qhov tseeb, nyob rau hauv no thiab ua kom tiav cov kev loj hlob ntawm computers, thiab computers tsis tshua ntau, tab sis ho tsis xaus nws zoo tag nrho.

Fifth tiam (invisible computers)

Nws yog qhov no tiam ntawm computers, peb yuav pom tau cov piv txwv ntawm cov ntsiav tshuaj, e-phau ntawv thiab lwm yam handheld computers. Lawv tau Ameslikas xeeb raws li ib txoj kev los mus ua kom koj lub computer raws li compact thiab yooj yim, tab sis tsis raws li ntau raws li zoo tib yam, nyob ruaj ruaj PCs los yog laptops. Tab sis lawv nrees nyob nws tus kheej me me nyob rau hauv lub lag luam thiab khov kho tuav nyob rau lawv txwv chaw rau decades.
