Sab nraud computer nco

Lub advent ntawm lub computer thiab, raws li, lub virtual ntaub ntawv khaws tseg rau ntau yam electronic media, coj mus rau qhov tseeb hais tias peb yuav tsum tau ntau dua thiab ntau ntaub ntawv repositories. Uas yog vim li cas cov sab nraud xov xwm los ntawm kev uas cov ntaub ntawv yuav nkag mus rau koj tus kheej lub computer yog invented rau lub cia thiab sib pauv ntawm cov ntaub ntawv.

Yog li, tag nrho cov ntawm cov computer lub cim xeeb yuav tsum tau muab faib ua ob qhov chaw:

- tus kheej hluav taws xob (internal) nco;

- Sab nraud nco PC yog nyob rau sab ntawm lub xov xwm.

Internal drives yog hu ua txhav los yog tsau, lawv muaj kos nyob rau hauv lub computer system unit thiab feem ntau hu ua ib qho nyuaj disks.

Raws li txoj cai, tus nqi ntawm cov ntaub ntawv nyob rau sab ntawm lub xov xwm yog muaj ntau lub sij hawm ntau tshaj li qhov ntim uas yog khaws cia ncaj qha rau hauv lub computer. Feem ntau, muaj cov rewriting tag nrho cov kev pab cuam thiab cov ntaub ntawv uas nkag tau mus yog tsis yuav tsum tau tag nrho cov sij hawm, thaum lub hard drive yog tsim los rau mus tas li cia ntawm lub ntaub ntawv tsim nyog: lub operating system cov kev pab cuam, cov ntaub ntawv, ntaub ntawv sau npe thiab thiaj li nyob.

Thaum lub caij, lwm cim xeeb ntawm cov computer yog sawv cev los ntawm ib tug lossis loj ntau yam ntawm gadgets, tab sis nws cov thawj sawv cev twb tau consigned mus rau lub yav dhau los muag nthas disk los yog, ntau tsuas, li ib txwm muag nthas disk. Cov muag nthas disks yog tso rau hauv lub qhib tsav computer, thiab lawv nco yog 1,44 megabytes.

Multimedia kev loj hlob coj mus rau lub rov tshwm sim thiab kev loj hlob ntawm lwm yam sab nraud cia xov xwm nyob rau hauv uas cov ntaub ntawv (feem ntau yog cov suab paj nruag, movies, kev ua si) yog nyob rau hauv ib tug tus kheej lub computer. Qhov no lwm computer nco hu ua laser CDs (Compact Disks). Sau ntawv cov ntaub ntawv mus rau lawv yog ua nyob rau hauv cov ntawv no. Thiab yog hais tias lawv yog tsim los sau cov ntaub ntawv nyob rau tib lub sij hawm, lawv muaj ib tug CD-ROM title, thaum lub log yog tsim rau ntau cov ntaubntawv povthawj siv thiab overwriting ntawm cov ntaub ntawv, xa mus rau raws li CD-RW. Lub peev xwm ntawm ib tug txheej txheem CD-ROM laser xws li los ntawm 690 mus ob txhiab megabytes.

Sab nraud computer nco yog nyeem nrog laser discs siv ib tug CD-ROM-drives, uas yog sab hauv thiab sab nraud.

Ib tug ntau dua volume ntawm DVD discs yog tsim feem ntau rau cov ntaubntawv povthawj siv thiab kis tau tus mob ntawm movies. Sib cais ntawm ROM, RW, raws li zoo raws li nyeem cov ntaub ntawv los ntawm lawv yuav siv sij hawm qhov chaw nyob rau hauv lub hauv paus ntawm CD-ROM tsav.

Yog lwm, feem ntau nrov thaum lub caij hom ntawm cov ntaub ntawv - ib tug computer lwm nco, uas yog hu ua tus flash-nco. Sau ntawv cov ntaub ntawv nyob rau hauv cov ntaub ntawv no yog ua rau lub nti uas muab siab cov ntaub ntawv kev ncaj ncees raws li cov kev kub ceev nyeem ntawv thiab teev ntaub ntawv. Flash drive rau hnub tim tau tau nco tej chaw tsis tau tsuas yog raws li ib tug computer gadget, tab sis kuj raws li ib tug cov ntaub ntawv cia rau txawb tes, cov koob yees duab thiab lwm yam khoom uas yuav tsum tau ib tug ntaus ntawv rau cov ntaubntawv povthawj siv cov ntaub ntawv. Lawv tuaj nyob rau hauv ntau yam ntawm ntau thiab tsawg pab, thiab muaj peev xwm kuj muaj ib tug txawv npaum li cas mus rau ob peb kaum tawm ntawm gigabytes.

Cov sab nraud nco txog ib tug computer, uas lub sij hawm ntawd kom cov coob tagnrho, hu ua lwm hard drive. Lawv ntim tau npaum li cas mus rau ob peb terabytes, thiab cov cia siab rau ntawm cov ntaub ntawv cia tso zis hnov. Cov nyuaj drives yog kev cob cog rua lub computer siv USB-ports. Tsis tas li ntawd, lawv ntaus ntawv yuav tsis tau tsuas yog ua raws li ntxiv cov ntaub ntawv cia, tab sis kuj yuav ua (nrog ib tug qhov kev twb kev txuas mus rau ib tug computer) raws li ib tug continuation ntawm lub computer nco nws tus kheej. Yog li, muaj peev xwm yuav muab cov ntaub ntawv yuav tsum tau rau tag nrho cov lag luam ntawm lub system. Qhov no yog piv txwv li cov sab nraud nco.

Progress tsis sawv tseem, thiab lwm yam xov xwm tas li kev txhim kho. Cov ntaub ntawv tagnrho loj hlob, kom lawv kab ntsab thiab kev cia siab. Txawm li cas los, yeej ib txwm muaj nqis nco ntsoov tias tej khoom siv yuav tawg cia nyob rau hauv txhua lub caij. Uas yog vim li cas tag nrho cov ntaub ntawv tseem ceeb cia rau hauv koj lub computer, nws yog tsim nyog los theej tawm.
