Cob phum nco yog siv rau khaws cia ntaub ntawv

Ib txhia neeg xav hais tias qhov no yog ib tug heev yooj yim ntxiv, ua rau ntau piav yuav tsum tau? Tab sis muaj cov neeg nug cov nqe lus nug "Cob phum cia ntaus ntawv yog siv rau dab tsi?", Thiab nws yog tsis yooj yim dua, yog li ntawd kuv xav mus ua ib tug me ntsis ntawm clarity nyob rau hauv relation mus no lub npe.

Yuav ua li cas yog ib tug nyeem xwb nco?

Cob phum nco yog siv los khaws cov ntaub ntawv nyob rau hauv lub tshuab hluav taws xob daim ntawv. Muaj lwm, ntau to taub rau qhov dog dig neeg siv hais. Cob phum nco yog siv los khaws cov kev pab cuam uas yog siv nyob rau hauv hluav taws xob pab kiag li lawm. Feem ntau nyob rau hauv daim ntawv ntawm ib tug duab plaub, tsis pub dhau uas yog qhov tsim nyog kho vajtse, uas tej zaum yuav muab cia rau ib tug tsawg tus nqi ntawm cov ntaub ntawv nyob rau hauv ib qhov chaw uas tsis muaj voltage yog thov qhov. Nyob rau hauv lwm yam lus, lub ROM yog lub zog sab nraud nco nyob rau hauv uas yog muab thiab qhov tsim nyog cov ntaub ntawv. Yog hais tias ib tug neeg nyeem cov lus no, peb yuav xaus hais tias nws yog twb siv cov ROM raws li enjoying cov ntaus ntawv. Yog hais tias koj xav mus saib lub ntaus ntawv tus kheej, nws yog tseem ua tau kom ua li cas. Yuav ua li cas - nws yog nyob ntawm devaysa uas nyeem no tsab xov xwm. Yog hais tias ib tug computer, koj yuav tsum tshem tawm cov kev nkag vaj huam sib luag ntawm lub system unit thiab saib rau pem hauv ntej ntawm lub computer. Muaj koj yuav saib tau ib tug heev me me ntaus ntawv qhov luaj li cas ntawm 20 * 10 * 4 cm los yog li (nco ntsoov txoj cai tam sim no yog tham txog lub computer system unit, es tsis txhob ntawm ib tug laptop, tsis sib tov). ROM zoo li ib daim dub yas rau lub sab ntawm ki uake nrog hlau paib.

Yog li ntawd, peb yuav hais tias tsuas yog nco yog siv los khaws cov cov lus teb rau tag nrho cov tau cov lus nug, vim hais tias yog qhov twg tag nrho cov ntaub ntawv yog txais kev cawmdim, tus neeg siv tej yam nyob rau hauv koj lub computer. Tiam sis qhov ntau xov xwm yuav tsum tau tham tom qab.

Yuav ua li cas yog lawv?

Raws li tus yam ntxwv ntawm lawv cov kev siv yuav txawv ob hom ROM:

• Portable. Cov no muaj xws cov qhov cia ntaus ntawv uas yog yooj yim siv thaum tsiv los ntawm ib lub computer los yog hluav taws xob ntaus ntawv mus rau lwm lub. Cov no muaj xws hluav taws xob cia cov phau ntawv, flash xov xwm, thiab ntau lwm yam uas zoo sib xws li nyob rau hauv functionality.
• Nyob Ruaj Ruaj. Cov pab kiag li lawm yog tsim kom lawv yuav tsim kom muaj ib zaug thiab yuav txaus siab rau lub xyoo. Lub ROM yog ntsia tau rau hauv lub computer zwm rau hom.

Lub nyeem nkaus xwb puas txawv?

Kom txog rau thaum nyuam qhuav, lub ntsiab thiab feem ntau tseem ceeb sib txawv nruab nrab ntawm ob yog tus nqi ntawm cov ntaub ntawv uas muaj peev xwm muab sau tseg. Yog li ntawd, lub ntsiab muaj yog magnetic tapes thiab lawv derivatives - floppies, uas muaj ib tug cim xeeb ntawm pua pua los yog txhiab ntawm lub sij hawm me me tshaj lub computer hard drives. Tab sis lub sij hawm dhau, thiab tam sim no portable ROM nyob rau hauv cov nqe lus ntawm lub cim xeeb yog tsis inferior nyob ruaj ruaj, tej zaum raug hloov los ntawm qhov kev hloov ntawm ib tug computer hard disk. Tab sis txawm tam sim no, nws tseem yog ib tug tseem ceeb sib txawv:

• Loj. Feem ntau, portable cia li yog tseem tsim rau ib tug me me npaum li cas ntawm lub cim xeeb, li ntawd nws yog heev tej yam ntuj tso, lawv yog me me nyob rau hauv loj.
• Ntau hom kev sib txuas mus rau lub computer nws tus kheej, thiab txuas lub rooj zaum: nrog thiab sab nraud (sab nraum lub system unit thiab sab hauv nws).
• Tus nqi ntawm cov tshuaj tiv thaiv. Nws tej zaum pom ntau nyeem. Yog hais tias cov kev hloov ntawm cov ntaub ntawv ntawm folders yuav siv sij hawm vib nas this nyob rau hauv lub computer, ces hloov mus rau ib tug sab nraud ntaus ntawv nyob rau hauv lub computer lub cim xeeb yuav xav tau ib pliag.

Portable cia li

Rau portable cia li xws electronics yuav tsum muaj xws li:

• Hauv cia ntawm phau ntawv. Qhov no nyeem xwb nco siv los cia lossis loj nyiaj ntawm cov ntaub ntawv. Yog li ntawd, cov phau ntawv nyob rau hauv loj sib haum mus rau hauv lub niaj zaus cov phau ntawv ntawm daim ntawv, tab sis tus nqi ntawm cov ntaub ntawv uas yuav tsum tau muab tso rau hauv lawv, nyiam: nws yog mus txog rau 10 terabytes (xws li cov khoom yog nyob rau hauv lub dawb ua lag luam raws li ntawm no sau ntawv).
• Drives raws li laser tshuab (CD, DVD, thiab lwm yam). Tej zaum muaj ntau yam ntawm koj yuav nrhiav tau ib tug me me sau los ntawm xws nqa, uas yog ua si los yog movies, tab sis ib txhia yog tam sim no nyob rau hauv lub era ntawm hauv internet thiab dawb nkag tau mus rau cov lus qhia, yuav lawv rau lub tsev sau.
• Daim kab xev pab kiag li lawm (muag nthas disk, tam sim no suab tsis siv).
• Reusable hluav taws xob cia xov xwm los ntawm kev siv lub "flash" technology (nyob rau hauv cov neeg uas lawv yog hu ua flash drives). Ib tug me me nyeem xwb nco siv los cia cov ntaub ntawv uas mus txog rau ib tug ob peb units los yog kaum ntawm gigabytes.

Nyob Ruaj Ruaj cia li

Cov muaj xws li:

• Hard drives uas yog ntsia nyob rau hauv lub computer.
• Tag nrho cov lus qhia systems tsim cov ntaub ntawv uas muaj peev xwm yuav pom nyob rau hauv lub loj loj txuam nrog ntawm cov ntaub ntawv chaw.

Lub tswv yim thaum xaiv ROM

Thiab tam sim no, kev paub txog lub tag nrho thiab cov kev, uas yog nyeem ntawv nkaus xwb puas, tsis muaj mob yuav paub uas ntaus ntawv xaiv. Tab sis nyob rau hauv kom tsis txhob tsis kaj siab chim siab, ib tug yuav tsum xub to taub lub system ntawm suav cov ntaub ntawv. Qhov tseeb hais tias xws li hauj lwm rau lub binary system, uas yog ib qho tseem ceeb rau tus xov tooj 1024. Nws thiaj li tau tshwm sim hais tias tus 1 gigabyte yog 1024 megabytes, 1 megabyte yog 1024 kilobytes, thiab hais txog. D. (Qhov no yog ib lub npe rau ib tsab xov xwm). Ib tug cab kuj manufacturers tej zaum ncaj thiab noj raws li ib lub hauv paus rau tus xov tooj 1000 rounding nqi. Koj muaj peev xwm yuav ib tug flash-cab kuj 16 000 megabytes, thiab koj hais tias qhov no yog 16 gigabytes, tab sis nyob rau hauv kev muaj tiag yuav muaj tsuas 14.9 GB. Thiab tam sim no mus rau lub tswv yim:

• Thaum muas, yeej ib txwm xyuas seb qhov kev cai tswjhwm denomination yog lub luag hauj lwm tsav tiag tiag qhov teeb meem no. Nug koj tus neeg muag mus xyuas lub installed nyob rau hauv-lub khw computer. Qhov lub khws uas cov neeg muas zaub zoo siab, xws li ib tug txheej txheem yog muab rau cov kev cai, yog li ntawd tsis txhob txhawj thiab xav tias dawb nug.
• Tshawb xyuas tas mus li ntaus ntawv cia rau lwm puas tsuaj. Kos rau lub lag luam los ntawm point №1 muaj kuj yuav pab tau.
• Xyuas qhov zoo ntawm cov zes. Yog hais tias koj pom kev puas tsuaj, xaiv lwm yam khoom.
• Thiab nco ntsoov txog tus cai ntawm lub buyer nyob rau hauv cov ntaub ntawv ntawm yuav tsis muaj zoo khoom.

Thiab thaum kawg, cia peb rov qab ua: nyeem xwb nco siv los khaws cov zoo li cas? Cov ntaub ntawv xa nyob rau hauv hluav taws xob daim ntawv. Hopefully, tom qab nyeem ntawv no tsab xov xwm, tej kev nyeem ntawv yuav tsum tau teb lo lus nug no tsis muaj hesitation.
