Cyclic redundancy cheki (CRC) is algorithm inogona kushandiswa kuona shanduko mune data. Mune a Zip or RAR archive, kana chinhu chefaira chakachengetwa mairi, kunze kweiyo yakamanikidzwa faira data, iyo CRC kukosha kweiyo uncompressed faira data inoverengerwa uye kuchengetwa pamwechete. Saka kana chinhu chefaira chabviswa, iyo unzip kana unrar chirongwa chinofanirwawo kuverenga kukosha kweCRC yedata isina kudzvanywa uye kuienzanisa neyakachengetwa. Kana dzakafanana, saka iyo data yefaira inofanira kunge isina kusimba. Zvisinei, kana vakasiyana, zvino izvi zvinonzi CRC kukanganisa, zvinoreva kuti data yefaira yakashandurwa. Saka, isu tinoshandisa iyo CRC kukosha kutarisa kana iyo faira data iri mudura ine huori kana kwete.
CRC kukosha kwakanyanya. Saka kunyangwe kana imwe byte yefaira data ikashandurwa, kukosha kweCRC kunenge kusingaenderane neiyo yekutanga. Muchiitiko chakadaro, vakawanda Zip or RAR mapurogiramu acharamba kuunzip kana unrar iyo data data. Asi chaizvoizvo, most yemabhayiti achiri OK. Yedu DataNumen Zip Repair uye DataNumen RAR Repair inogona kudzoreredza aya data kubva mudura, saka kuderedza kurasikirwa kwedata.
Zvakare dzimwe nguva, iyo faira data yakamira, asi iyo CRC kukosha kwayo pachayo yakakuvadzwa. Muchiitiko chakadaro, kana zvimwe Zip or RAR maapplication anoramba kuburitsa data refaira, yedu DataNumen Zip Repair uye DataNumen RAR Repair inogona kukubatsirawo.
