Zvose Zvaunoda Kuziva Nezve FAT32, exFAT, FAT16, & FAT12
Faira Allocation Table (FAT) ipurogiramu yefaira yakasikwa neMicrosoft muna 1977.
FAT ichiri kushandiswa mazuva ano seyo inoshandiswa faira system yeDragppy drive media uye inoshandiswa, madivhidhiyo ekuchengetedza masimba akadai semafuta ekutsvaga uye mamwe majekiti akachengetedza zvakasimba se-SD makadhi.
FAT yakanga iri iyo huru yefaira inoshandiswa mune zvose zveMicrosoft consumer operating systems kubva MS-DOS kuburikidza neWindows ME. Kunyange zvazvo FAT ichiri nzira yakatsigirwa pamitambo yeMicrosoft inoshandiswa itsva, NTFS ndiyo inotakura faira system yakashandiswa mazuva ano.
Iyo File Allocation Table file system yakaona kufambira mberi kwenguva yakawanda nekuda kwekudiwa kwekutsigira hurukuro dzakaoma dze disk uye mazana makuru emafaira.
Pano pane zvakawanda pane dzimwe shanduro dzeFAT file system:
FAT12 (12-bit Faira Kugovera Table)
Shanduro yekutanga yakashandiswa zvikuru yeFAT file system, FAT12, yakatangwa muna 1980, pamwe chete neshanduro dzekutanga dzeDOS.
FAT12 ndiyo yaiva yepayipi faira yeMicrosoft operating systems kuburikidza ne MS-DOS 3.30 asi yakashandiswawo mumasangano mazhinji kusvika MS-DOS 4.0. FAT12 ichiri iyo faira yakashandiswa pane imwe nguva floppy disk iwe uchawana nhasi.
FAT12 inotsigira hukuru hwemotokari uye inotakura huwandu huri kusvika 16 MB uchishandisa masikisi 4 KB kana 32 MB uchishandisa 8 KB, ine nhamba yakawanda yefaira 4 044 pane imwe chete (kana uchishandisa masikiti 8KB).
Faira mazita pasi peFAT12 haagoni kudarika huwandu hwemunhu muganhu wevanhu vatatu, pamwe chete 3 pakuwedzera .
Zvimwe zvefaira zvefaira zvakatanga kuiswa muFAT12, kusanganisira yakavanzika , kuverengerwa-chete , hurongwa , uye yevheti yepamusoro .
Cherechedza: FAT8, yakatangwa muna 1977, ndiyo yaiva yekutanga yechokwadi yeFAT file system asi yakashandiswa zvishoma uye pane dzimwe shanduro dzemakombiyuta epanguva ino.
FAT16 (16-bit File Allocation Table)
Yechipiri yekushandiswa kweFAT yaiva FAT16, yakatanga kuiswa muna 1984 muPC DOS 3.0 uye MS-DOS 3.0.
Shanduro shoma shoma yaFAT16, inonzi FAT16B, ndiyo yaiva yepayipi faira ye MS-DOS 4.0 kusvika pa MS-DOS 6.22. Kutanga na MS-DOS 7.0 neWindows 95, imwe shanduro yakagadziridzwa, inonzi FAT16X, yakashandiswa panzvimbo.
Zvichienderana nebasa rekushanda uye mashizha emasumbu akashandiswa, huwandu hwemotokari huwandu hweFAT16-yakagadziridzwa motokari inogona kuva kubva pa2 GB kusvika 16 GB, iyo inotevera muWindows NT 4 ne256 KB masumbu.
Faira hukuru paFAT16 inotakura mairi kunze kwe 4 GB neGirasi Yesepa Kubatsira yakabvumirwa, kana 2 GB pasina iyo.
Nhamba yakawanda yefaira inogona kubatwa paFAT16 vhuti 65 656. Kungofanana neFAT12, mazita emafaira aive akareba 8 + 3 asi asi akaendeswa kumashoko 255 anotanga neWindows 95.
Nzvimbo yekuchengetedzwa kweiyo archive yakaiswa muFAT16.
FAT32 (32-bit File Allocation Table)
FAT32 ndiyo shanduro yezvino yeFAT file system. Yakatangwa muna 1996 nokuda kweWindows 95 OSR2 / MS-DOS 7.1 vashandisi uye yaiva yepayipi faira yekutengesa Windows versions kuburikidza ne Windows ME.
FAT32 inotsigira motokari inotakura kusvika ku 2 TB kana kunyange yakakwirira se16 TB ne 64 KB masumbu.
Kufanana neFAT16, faira mazai paFAT32 inotakura max kunze kwe 4 GB neGuru File Support yakashandurwa kana 2 GB pasina iyo. Shanduro yakashandurwa yeFAT32, inonzi FAT32 + , inotsigira mafaira ari pedyo ne256 GB muhukuru!
Kusvika mairi 268 173 300 mafaira anogona kuwanikwa pane FAT32 yevhesi chero bedzi iri kushandisa 32 KB masumbu.
exFAT (Yakaderedzwa File Allocation Table)
exFAT, yakatanga kuziviswa muna 2006, ndeye imwe faira system yakagadzirwa neMicrosoft kunyange isiri "FAT" yeFAT version shure kweFAT32.
exFAT inonyanya kurongedzerwa kushandiswa pamashandisirwo emagetsi anoshandiswa sezvinofambisa mhepo, SDHC uye SDXC makadhi, nezvimwewo.
exFAT inotsigira zviri pamutemo zvinyorwa zvekuchengetedza zvigadzirwa zvinoshandiswa kusvika kune 512 TiB muhukuru asi inoretically inogona kutsigira zvinotakura zvakakura se 64 ZiB, iyo yakakura kudarika chero mhizha inowanikwa seyiyo kunyorwa.
Kutsigirwa kwevanhu vemu 255 mavara mafaira uye rutsigiro kusvika mairi 2,796,202 mafaira pakurongwa kwemashoko zvinhu zviviri zvinokosha zveexFAT system.
Iko yeFFAT file system inotsigirwa nezvose zvinoshandiswa neWindows (vakwegura vane zvinyorwa zvinosarudzwa), Mac OS X (10.6.5+), uyewo pane vazhinji TV, ve media, nezvimwe zvigadzirwa.
Kufambisa Files Kubvira NTFS kusvika kuFAT Systems
Fichi encryption, file compression , object permissions, disk quotas, uye iyo yakakoswa mafaira mafaira inowanika muTFF file system chete - kwete FAT . Zvimwe zvinhu, sezvinowanzoitika pane zvandakambotaura muhurukuro iri pamusoro, zvinowanikwawo pane NTFS.
Zvichienderana nekusiyana kwavo, kana iwe ukaisa faira yakavharidzirwa kubva kuTV yeFNFS kusvika pane FAT-yakagadzirirwa nzvimbo, faira inorasikirwa nemamiriro ayo ekuteterera, zvinoreva kuti faira inogona kushandiswa seyemazuva ose, isiri yakavharwa faira. Kunyora faira nenzira iyi kunongogona chete kumushandi wepakutanga akavhara faira, kana kuti chero umwe mushandisi akapiwa mvumo nemuridzi wepakutanga.
Kufanana nemafuta akavharidzirwa, sezvo FAT isingatsigeri kudzvinyirira, faira yakanyimirirwa inongodzokoromorwa kana ichinyorwa kubva muTVFS uye kuFAT yakawanda. Semuenzaniso, kana iwe ukanyora faira yakanamatira kubva kuDBD disk hard to floppy disk FAT, iyo faira ichakudzimbura kamwe chete isati yakachengetwa kudipikisi nokuti FAT file system pane nzvimbo inoenda kune vhidhiyo haina kukwanisa kuchengeta mafaira akaomeswa .
Kunyatsodzidza Kuverenga paFAT
Kunyange zvazvo iri kunze kwekukurukurirana kweFAT kuno, kana iwe uchida kuziva zvakawanda nezvekuti FAT12, FAT16, uye FAT32 zvigadzirwa zvakarongeka zvakarongeka sei, ona FAT Filesystems naAndries E. Brouwer.
