Yintoni inkqubo njengenani elinekona ezintandathu eziphela

Wonk 'ubani enxibelelana ikhompyutha okanye ezinye izixhobo idijithali, wadibana uhlobo irekhodi 10FEF angaziwayo ezibonakala ukuba uninitiated ethile cipher. Yintoni oyena nobangela ezi mpawu? Kubonakala ukuba amanani nje. Abo osebenzisa njengokom ngokwendlela yokunombola.

iinkqubo inani

Ngamnye wesikolo uyazi, okanye ubuncinane weva ndaweni ukuba onke amanani esidla ukusebenzisa, ibe inkqubo wokugqibela. Eli gama luthwala nje kungenxa yokuba abalinganiswa ezahlukeneyo kulo ezilishumi (0 ukuya ku-9). Naliphi na inani kwinkqubo yethu yesiqhelo nga kubhalwa kusetyenziswa kuzo. Noko ke, kwenzeka, kulula ukuyisebenzisa akusoloko. Umzekelo, ukutshintshisana ngolwazi phakathi izixhobo lwedijithali elula ukusebenzisa inkqubo amanani, apho kukho kuphela amanani amabini: "0" - akukho uphawu - okanye "1" - umqondiso (ombane okanye into enye). Ibizwa ngokuba yokubini. Noko ke, ukuba ukuchaza iinkqubo izixhobo ezifana nayo kuya kufuneka ukuba enze elide kakhulu yaye kunzima ukuqonda ukurekhoda. Ngoko ke, ukuba kusungulwe inkqubo njengenani elinekona ezintandathu.

Ingcamango kwenkqubo njengokom

Kutheni isixhobo i-digital kusetyenziswa yinkqubo eye imiqondiso ezahlukeneyo elinesithandathu? Njengoko yaziwa, ulwazi iikhompyutha ezidluliselwa ngohlobo bytes, leyo iqulathe ngokokuqhelekileyo amasuntswana 8. A unit data - igama kumatshini - iquka bytes-2, ngamanye amasuntswana 16. Ngaloo ndlela, esebenzisa oonobumba ezahlukeneyo elinesithandathu uyakwazi ukuchaza ingcaciso kwisuntswana incinane olo tshintshano. Inkqubo njengenani elinekona ezintandathu eziphela luquka amanani zethu njengesiqhelo (ngokwendalo, 0 ukuya 9) kwaye emise yokuqala njengoko oonobumba be-alfabhethi Latin (A, B, C, D , E, F). Ngawo aba balinganiswa ngokuqhelekileyo ebhaliweyo nayiphi iyunithi ulwazi. Bayakwazi ukwenza nayiphi na imisebenzi arithmetic. Oko kukuthi, ukudibanisa, ukuthabatha, ukuphinda-phinda, hlula. Kwakhona Umphumo iya kuba njengenani elinekona ezintandathu.

apho kuyimfuneko

inkqubo njengokom isetyenziselwa ukurekhoda iikhowudi impazamo. Kusenokwenzeka ukuba zenzeke ziziveliso ze-software ezahlukeneyo. Ngokomzekelo, njalo-coded iimpazamo kwinkqubo yokusebenza. inombolo nganye kulo mgangatho. Ungafumanisa ukuba uhlobo imposiso yenzekile ngokuthi decrypting usebenzisa imiyalelo kule nkqubo. Kwakhona, ezi iisimboli zisetyenziswa xa bebhala iinkqubo iilwimi-kwinqanaba elisezantsi, ezifana ulwimi ibandla. inkqubo njengenani elinekona ezintandathu eziphela nangoku ukuthandwa badwelisi benkqubo, nangenxa kwanangamacandelo alo lula kakhulu ukuba zitshintshwe zibe yokubini, leyo "lweenkobe" kulo lonke ubugcisa yedijithali. Ekubeni le miqondiso kwakhona bechaza amacebo umbala. Ukongeza, kuba ngokuphelele zonke iifayile kwindlela yakho (zombini itekisi kunye nemizobo, yaye umculo okanye ividiyo) zingeniswe emva zosasazo ngokweesirisi codes yokubini. Jonga umthombo eyona nto ingcono kanye njengoko abalinganiswa elinekona ezintandathu eziphela kwishumi.

Kakade ke, naliphi na inani angabhalwa kwiinkqubo inani ezahlukeneyo. Oku kwesishumi kwaye yokubini, kunye hexadecimal. Ukuze ukuguqulela igama ukusuka omnye kubo ukuya kwenye, kufuneka usebenzise inkonzo enjalo, njengoko ngumguquleli iinkqubo inani, okanye yokuyenza ngokwakho na ngoncedo algorithm.
