Sab nraud computer nco

Cov ntsiab lus niaj hnub no tsab xov xwm no rau lwm lub cim xeeb ntawm computers. Tiam sis ua ntej kuv xav hais tias ib tug ob peb lo lus hais txog ib tug kev ua yuam kev, uas muaj pov thawj yuav tsis tshua muaj "tenacious". Lwm lub tsev kawm ntawv ntawm peb zaj lus qhia thaum kawm internal system thaiv ntaus ntawv , cov lwm yam qhia kom meej yog ib tug tseem ceeb - RAM. Lub cev, nws yog sawv cev los ntawm tej daim soldered rau textolite plank nrog ob tug kab (zuag), zawv zawg hu, uas txuas mus rau lub system board. Piv txwv li, thaum lawv hais tias yog tsis txaus nco, nws implies ib tug me me npaum li cas ntawm RAM. Tog twg los general los yog rau ib co daim ntawv sau npe. Txawm li cas los, tej zaum cov kev siv ntawm lub sij hawm "lwm nco". Qhov no yog tsis muaj tseeb, yam tsawg kawg vim hais tias, piv txwv li, tsis yog leej twg los mus nrog lub tswv yim rau hu cov phau ntawv "nco". Cov phau ntawv - nws yog rau hauv xov xwm, thiab lub cim xeeb - ib yam dab tsi txawv heev.

Yuav ua li cas yog tej yam yog meant ntawm lub sij hawm "lwm nco"? Nyob rau hauv lub saum toj no-hais RAM muaj ib tug tseem ceeb disadvantage, uas manifests nws tus kheej nyob rau hauv lub poob tag nrho cov ntaub ntawv khaws tseg nyob rau hauv lub nti ntawm tus xovtooj ntawm nyob rau txhua fais fab tuag. Yog li ntawd, nws yog tsuas yog siv thaum lub computer ntshav tam sim no suav, thiab rau ntev-lub sij hawm cov ntaub ntawv cia lwm nco yog siv. Qhov no nyuaj tsav, flash drive, tus tsav nyeem / sau CD-ROM tsav, txawm lub tshuab luam ntawv, muaj ib co zos. Hais tias yog, tag nrho cov pab kiag li lawm nyob rau hauv uas lub sam xeeb ntawm ntaub ntawv kaw tseg tsis yog nyob rau hauv lub xub ntiag ntawm hluav taws xob.

Tag nrho cov neeg siv cov ntaub ntawv, nrog rau cov kev khiav hauj lwm qhov system, muab cia rau hauv xws xov xwm. Piv nrog rau lub RAM, cov pab kiag li lawm muaj ib tug ntau dua muaj peev xwm, thiab nyob rau hauv tej rooj plaub zoo unlimited. Piv txwv li, yog hais tias tus muaj peev xwm ntawm cov modules ntawm cov niaj hnub lub computer yog ib tug nruab nrab ntawm 4-8 GB, tus nqi ntawm cov hard drive yog tsis tshua muaj tsawg tshaj li 250 GB. Siv cov ntaub ntawv cia tshem xov xwm (CD-ROM), koj muaj peev xwm, nyob rau hauv kev tshawb xav, txuag txom kwj ntawm cov ntaub ntawv.

Sab nraud cov cim xeeb yog lub cev muaj cia li mus rau ntau yam kev khiav hauj lwm hauv paus ntsiab lus. Ib qho ntawm thawj ntawm cov kev daws yog cov muag nthas disk. Lub saj zawg zog polymeric substrate nyob rau hauv daim ntawv ntawm ib tug disk coated nrog ib tug sib nqus txheej, qhov chaw uas ib tug qhia tshwj xeeb uas magnetizable cov ntaubntawv povthawj siv taub hau tsav. Lub hauv paus ntsiab lus yog yuav luag tib yam li nyob rau hauv lub qub cassettes rau audio thiab video kiag li lawm.

Yuav luag nyob rau tib lub sij hawm muaj zoo yam ntxwv kev daws teeb meem, npe hu ua Winchester. Lub tsev nyob tso dog dig inflexible tsav tam sim no ntawm ib tug nonconductive khoom, coated nrog ib tug sib nqus txheej. Txij li thaum cov ntaubntawv povthawj siv taub hau yog tsis ncaj qha nyob rau hauv kev sib cuag nrog tus nto, "flying" saum huab cua kwj twb tau mus ho tsa lub disc kev sib hloov ceev, thiab yog li ntawd, qhov kev kawm ntawm cov tag nrho lub ntaus ntawv.

Ib tug nkaus txawv hauv paus ntsiab lus ntawm cov lag luam yog siv nyob rau hauv drives kev nyeem ntawv / sau CD-ROM tsav. Raws li computer pab neeg ntawm cov laser beam nyob rau hauv ib txoj kev presses nyob rau hauv ib tug nyias hlau grooves. Thaum nyeem ntawv rau hauv tib lub beam reflected los ntawm daim iav thaub qab txheej, ib tug photocell yog tej thiab analyzed. Yog li recovering cov ntaub ntawv kaw tseg.

Cov no yog cov ib co hom nco kiag li lawm. Los ntawm txoj kev, thaum lub sij hawm thawj 8086 kev txiav txim siab ntawm computers muaj, uas yuav justly yuav hu ua cov sab nraud nco. Cov no yog lub ib thooj ntawm cov expansion modules ntawm RAM, uas tsis muaj tsev nyob hauv lub nti. Tsis zoo li niaj hnub tuav hais tias tus ntaus ntawv yog ib tug tiag tiag sab nraud.
