Tsis tas li ntawd, koj yuav tsum qhia kom meej rau cov kev kawm cheeb tsam, nrog rau kev hwm rau cov uas nws yog teem. Ntawm qhov one hand, nws yuav ua tau ib lub cim ceev heev rau hauv ib lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob, los yog tus ntiv tes xaum ntawm CD-ROM tsav. Ntawm qhov tod tes, nws yog ib qhov chaw nyob ntawm tus tsav uas siv Internet browser rau nws cov kev xav tau. Nyob rau hauv txhua rooj plaub, nws yog lub cim xeeb, uas tsub kom qhov kev kawm ntawm koj lub PC.

Txog hnub no, tus nqi no yuav ua tau zoo ib yam ntawm lub computer ntawm 2 mus rau 64 MB nrog ib tus sib npaug ntawm 2, thiab rau lub laptop nws yooj yim dua - tsuas yog 2 kev hloov kho nrog 32 thiab 64 MB. Qhov cim xeeb no tsis pub kom koj ua tau zoo dua, tab sis nws kuj tau txais 15 feem pua ntxiv raws li qee lub sijhawm.

Processor

Tom ntej no, nrhiav tawm dab tsi lub cache mus rau lub processor. Nyob rau hauv cov ntaub ntawv no, peb txhais ib lub cim ceev ceev heev, uas yog kev nkag mus rau hauv lub semiconductor crystal ntawm CPU. Nws yuav khoom commands thiab cov ntaub ntawv feem ntau siv No lub caij nyoog ntawm cov PCs niaj hnub no. Cov tshiab versions ntawm processors muaj nruab nrog peb-theem xws li subsystems nco. Qhov no muaj qhov zoo ntawm kev ua haujlwm.

Actuator

CD-ROM drives tseem equip lawv li nrog ib cache-xws li ib tug ceev thiab tsis nto nco. Cov txiaj ntsim ntawm kev daws qhov no yog pom tseeb - nce kev tsim khoom tsim nyog ntawm cov nqi tsawg. Yog li no, lo lus teb rau lo lus nug, qhov cache yuav zoo li cas, yuav zoo tib yam li rau qhov nyuaj disk. Qhov no yog ib tug nti ntsia ntawm tus tsav, uas ua rau kom ceev ceev ntawm cov ntaub ntawv txauv ntawm tus tsav thiab lwm yam ntawm tus kheej lub computer.

Browser

Tag nrho cov yav tas los tau coj los siv ua piv txwv hauv kev kho vajtse. Tib qho xwm txheej nrog tus browser ua tiav qhov programmatically. Cov tib algorithm yog siv nyob rau hauv lub operating system "windose" - thiab no nws yog hu ua "sib puav ntaub ntawv". Tab sis nws 's yooj yim mus xav txog kev lag luam ntawm tej lub cim subsystem nrog tus piv txwv ntawm tus browser. Tag nrho tib yam, tab sis ntau yooj yim. Lub cev - qhov no yog cov ntaub ntawv ib ntus uas yuav tsum tau ua los ntawm daim ntawv thov no rau kev ua haujlwm thiab uas muab cia rau hauv daim hard disk. Ntawd yog, qhov browser ceev ib qho chaw hauv kev ua hauj lwm thiab khaws cov ntaub ntawv muaj. Yog hais tias qhov kev kho mob muaj xws li ib lub cim xeeb loj, ces qhov no nws tuaj yeem ua tau ntau yam. Cia saib qhov piv txwv ntawm Internet browser "Opera" yuav ua li cas rau nruab lub cache.

Yuav muaj ib tug nco-down daim ntawv teev uas tau qhov tseem ceeb ntawm lub cim xeeb uas yog tshwj tseg rau cov kev xav tau ntawm daim ntawv thov.

Xaus

Cache nco yog ib qho tseem ceeb ntawm cov computers uas niaj hnub. Nyob rau hauv ib rooj plaub, nws tau ua raws li cov programmatically, nyob rau hauv lwm tus nws yog DVR hauv kev kho vajtse. Qhov tshwm sim ntawm nws txoj kev siv yog ib qho kev nce hauv kev ua tau zoo ntawm lub tshuab computer. Yog tsis muaj nws, nws tsuas yog tsis yooj yim sua kom xav txog kev ua hauj lwm ntawm tej tus niaj hnub PC.
