Magnetic Tape vs Sib Nqus Disk
Cov kab hlau nplaum thiab cov hlau nplaum yog cov khoom siv los khaws cov ntaub ntawv. Sib nqus disks yog hlau discs uas yog coated nrog cov khoom tshwj xeeb los khaws cov ntaub ntawv. Magnetic tapes yog cov polymers uas tau coated nrog cov khoom tshwj xeeb los khaws cov ntaub ntawv. Magnetic tapes thiab magnetic disks yog siv dav hauv cov teb xws li audio cassettes, video cassettes, computer hard disk drives, floppy drives thiab ntau lwm yam kev siv. Muaj ntau qhov zoo ntawm ob qho tib si ntawm cov ntaub ntawv khaws cia no, thiab lawv tseem ceeb hauv kev nkag siab txog cov cuab yeej kho vajtse ntawm cov khoom siv uas siv lawv. Nyob rau hauv tsab xov xwm no, peb yuav tham txog dab tsi magnetic tapes thiab magnetic disks yog, lawv cov hauv paus ntsiab lus, qhov zoo thiab qhov tsis zoo ntawm magnetic disks thiab magnetic tapes, nyob rau hauv dab tsi daim ntaub ntawv magnetic disks thiab magnetic tapes siv, qhov zoo sib xws ntawm ob thiab thaum kawg. qhov sib txawv ntawm magnetic tapes thiab magnetic disks.
Magnetic Tapes
Ib daim kab xev sib nqus yog nyias thiab ntev yas strip coated nrog cov khoom siv magnetizable. Lub kaw lus xaj cov khoom siv magnetizable ntawm daim kab xev sib nqus raws li lub teeb liab tuaj. Cov txheej txheem nyeem ntawv tsuas yog ua tiav los ntawm kev xa daim kab xev ze ntawm lub kauj uas ua rau tam sim no uas tuaj yeem txiav tawm mus rau qhov qub. Sib nqus tapes kuj yog siv los ua cov ntaub ntawv hauv computer. Cov no tau siv ua ntej hard disk drives tau tsim. Sib nqus tapes tseem siv los khaws cov ntaub ntawv ntau heev rau kev siv tsis tu ncua. Daim kab xev nplaum yog ib qho khoom siv sib txuas. Cov ntaub ntawv tsuas yog nyeem tau raws li cov lus qhia serial. Sib nqus tapes feem ntau yog siv hauv Audio cassettes thiab video cassettes. Sib nqus tapes yog siv raws li cov ntaub ntawv khaws cia cov khoom siv nrog rau cov ntaub ntawv analog cov ntaub ntawv khaws cia.
Magnetic Disks
Ib daim hlau nplaum ua haujlwm ib yam li daim kab xev sib nqus, tab sis cov hlau nplaum feem ntau tuaj yeem khaws cov ntaub ntawv ntau dua li cov ntaub nplaum sib nqus. Lub ntsiab kom zoo dua ntawm magnetic disk yog cov ntaub ntawv tuaj yeem nyeem los ntawm txhua qhov chaw. Magnetic disk kuj yog portable dua li daim kab xev sib nqus. Lub khoos phis tawj hard disk yog cov khoom siv tseem ceeb uas siv cov khoom sib nqus. Sib nqus disks tsis shockproof. Ib qho kev poob siab tuaj yeem hloov pauv qhov kev sib nqus tam sim no ntawm cov khoom siv. Txawm li cas los xij, txij li cov kab hlau nplaum tsis muaj zog, lub caij nyoog ntawm kev poob siab yog tsawg. Sib nqus disks yog siv los ua cov ntaub ntawv digital khaws cia ntau dua li cov ntaub ntawv khaws cia analog. Ib qho chaw ntawm lub disk yog hu ua block. Qhov kev taw qhia sib nqus sib nqus ntawm qhov thaiv txiav txim siab seb nws puas yog digital 0 lossis 1.
Dab tsi yog qhov sib txawv ntawm Magnetic Disk thiab Magnetic Tape?
• Daim kab xev sib nqus muaj qhov chaw khaws cia uas tau kov los ntawm cov khoom siv sab nraud hauv daim kab xev, tab sis cov hlau nplaum tsis raug kov los ntawm ib qho khoom siv sab nraud.
• Cov ntaub ntawv nkag mus ceev ntawm daim nplaum nplaum yog nrawm dua li ntawm daim kab xev sib nqus.
• Sib nqus disks tuaj yeem tuav cov ntaub ntawv ntau dua ib chav tsev ntau dua li cov ntaub nplaum sib nqus; Txawm li cas los xij, cov khoom sib nqus yuav tsum tau khaws cia hauv lub tshuab nqus tsev kom txo tau qhov kev sib txhuam ntawm huab cua thaum tig.
