Muaj ib co hom computer nco: ROM tsav, lub RAM, nyuaj tsav, kho qhov muag drives thiab ntau yam portable cia kiag li lawm.

Raws li ib qho piv txwv ntawm ib qho ntawm cov hom ROM - nyeem nkaus xwb nco, yuav ua nyob rau hauv BIOS. Qhov no zoo ntawm ua tau rau hauv lub system board, thiab yog siv nyob rau thawj zaug rau theem ntawm booting lub computer. Qhov no nco muaj ib co ntawm feem ntau tseem ceeb software uas tsim ib tug thawj zaug kev twb kev txuas ntawm pab kiag li lawm rau cov lus qhia tswv yim thiab tso zis. BIOS los ua ib tug choj ntawm lub microprocessor thiab lub hard disk uas muaj lub operating system ntawm lub computer. Qhov no yog hu ua thiab loaded.

ROM - cov no yog cov computer nco hom uas yog sib txawv heev los ntawm tag nrho cov lwm leej lwm tus, vim hais tias lawv yog npaj rau high-ceev mus saib.

Tsis zoo li qhov twg ntawm lwm leej lwm tus yog hais tias nws yuav tsum muaj high-ceev saib, thiab nws nyeem voj voog yuav tsum tsawg heev, nws muaj tsis muaj feem mus, li ntawd, xws zog thiab tau ua tau. Cov hom yog distinguished los ntawm lub fact tias cov ntaub ntawv khaws tseg nyob rau hauv nws, thiab nyob ib lub sij hawm thaum lub computer yog kiag li muab tua.

RAM yog ib tug kev kub ceev nco ntaus ntawv, uas yog siv los khaws cov ntaub ntawv thaum lub sij hawm lub lag luam ntawm lub computer. Qhov no daim ntawv ntawm cov ntaub ntawv cia yog tau tsuas yog thaum lub sij hawm lub computer yog rau thiab khiav. RAM nco txog ib tug computer tau feeb muab modules uas yuav tau raug tshem tawm los yog hloov yog kev kawm. Lub hom phiaj ntawm qhov no zoo yog cia intermediate ntaub ntawv tau thaum lub sij hawm lub lag luam ntawm lub microprocessor. Lub sij hawm mus saib cov ntaub ntawv ntawd yuav tsum tsawg heev, yog li cov modules RAM thiab tshaaj tej uas yuav tsum tau.

Tseem muaj computer nco hom uas tso cai rau rau cia ntawm cov ntaub ntawv rau ib tug heev lub sij hawm ntev. Piv txwv li, hard disk drive yog ib tug ntaus ntawv uas yog npaj rau mus tas li cia cov ntaub ntawv thiab cov ntaub ntawv uas yog tsis erased thaum lub sij hawm shutdown. Feem ntau nyob rau hauv lub hard disk ntsia operating system thiab qhov tsim nyog daim ntawv thov software. Lub hard disk drive kev cob cog rua rau lub motherboard, thiab ib tug sab nraud cia ntaus ntawv.

Hom computer nco thiab lawv sib tham

Tej zaum kuj muaj yog ib tug teeb meem no thaum koj pom nyob rau qhov kev tshuaj ntsuam ib cov lus: "Tsis txaus virtual nco."

Koj yuav tsum xaiv cov disk sib puav cov ntaub ntawv thiab qhov luaj li cas ntawm cov ntaub ntawv.

Ib qho tseem ceeb hom - ib tug cache cim xeeb ntawm ib lub computer, uas ua lub zog ntawm ib tug tsis, cov kev pauv ntawm cov ntaub ntawv ntawm lub processor thiab RAM. Qhov no hom ntawm lub cim xeeb yog tus ceev tshaj, nws yog tsim nyog los xyuas kom meej du lag luam los ntawm high-quality computer. Feeb ntau, tus nqi ntawm tej lub cim xeeb yog hom twg 128-512 kilobytes.
