Hoton wani faffadan bayanai ne mai cike da yanayin ƙasa mai taken "CRC-32B Hash Algorithm" wanda aka nuna a cikin tuta mai shuɗi a saman. Tsarin gabaɗaya yana karantawa daga hagu zuwa dama, yana jagorantar mai kallo ta cikin manyan matakan algorithm ta amfani da siffofi masu sauƙi, kibiyoyi, da sassan da aka tsara launi. A gefen hagu, wani faifan zagaye mai suna "Input Data" ya ƙunshi tubalan guda uku da aka tara a launuka daban-daban, waɗanda aka yiwa alama da Data Block 1, Data Block 2, da Data Block 3. Waɗannan tubalan suna wakiltar guntun bayanai na gabaɗaya da ake sarrafawa, ba tare da nuna ainihin ƙima ba. Kibiya mai taken "Rarraba & Tsarin" tana nuna daga wannan faifan shigarwa zuwa tsakiyar zane.
Tsakiya, wani babban allon shuɗi mai haske mai taken "Rijistar Shift na Bit 32." A ciki, layin kwance na ƙananan akwatunan da babu komai yana nuna rajistar bit 32. A ƙarƙashin wannan layin akwai lakabin "Shift & XOR," wanda ke nuna ayyukan da aka maimaita yayin da bits ɗin bayanai ke motsawa ta cikin rajistar. A ƙasan wannan, an haɗa gunkin zagaye mai suna "XOR" ta hanyar kibiyoyi zuwa zane mai layi mai reshe mai taken "Raba ta Polynomial." Wannan zane mai faɗi yana nuna dabarun ra'ayoyin da aka yi amfani da su yayin lissafin CRC ba tare da haɗa da takamaiman ma'aunin polynomial ko cikakkun bayanai na aiwatarwa ba.
Daga tsakiyar allon, kibiya mai kauri ta kai ga gefen dama na hoton. A saman dama akwai ƙaramin kira mai karanta "Final XOR & Result," yana nuna ƙasa zuwa murabba'i mai zagaye kore mai laƙabi da "CRC-32B Hash." Wannan abun yana wakiltar ƙimar checksum na ƙarshe da tsarin ya samar.
Ƙasan infographic ɗin, gumakan ra'ayi guda biyu suna ƙarfafa manufar algorithm ɗin. A ƙasan ɓangaren shigarwa akwai ƙaramin alamar kullewa mai taken "Gano Kuskure," wanda aka haɗa ta da layin dige-dige zuwa babban yankin sarrafawa, yana jaddada cewa ana amfani da CRC don gano ɓarnar bayanai ta bazata. A ƙasan dama, alamar yatsa mai taken "Ingancin Bayanai" an haɗa ta da hash na ƙarshe, wanda ke nuna ra'ayin tabbatar da cewa bayanai ba su canza ba.
Tsarin gaba ɗaya yana amfani da launuka masu laushi, kusurwoyi masu zagaye, da kuma rubutu mai haske, tare da yalwar sarari don haka kwararar ta kasance mai sauƙin bi. Zane-zanen yana guje wa tsare-tsare na musamman ko ainihin sigogin lissafi, maimakon haka yana mai da hankali kan bayani mai zurfi, mai zurfi game da yadda bayanai ke gudana ta hanyar canzawa da ayyukan XOR don samar da checksum na CRC-32B.
