Kwikhompyutheni yekhompyutheni kunye nenethiwekhi, i- oct kwaye ibonisa nayiphi na i-8- ubuninzi. Uluhlu lwee-othetsi kwixabiso lemathematika ukusuka ku-0 ukuya ku-255.
Ixesha le- octet lisetyenziswe kwezinye iimeko, ezifana nokusebenza komculo, ukubhekisela kwiqela labantu abasibhozo okanye iinxalenye.
IiOtoti kunye neeAtesti
Zonke iinkqubo zeekhompyutheni zanamhlanje zizalise i- byte njengenani elingu-8-bit. Ii-ototi kunye nee -tes zifanayo kule ndlela. Ngenxa yesi sizathu, abanye abantu basebenzisa le mibini emibini. Ngokomlando, nangona kunjalo, iikhomputha zixhase ii -tes ezineenkalo ezahlukeneyo zeebitshi; ii-octet kunye nee -tes zithetha izinto ezahlukeneyo kulo mongo. Abaqeqeshi benethiwekhi baqalisa ukusebenzisa i- octet iminyaka emininzi edlulileyo ukugcina oku kwahlukileyo.
Iikhompyutheni zeekhompyutha zivame ukusebenzisa i- nibble yekota xa zibhekisela kwisixa esine -4-bit (isiqingatha se-octet enye okanye i-byte) kunokuthi yi-"i-octet yesiqingatha" (okanye "i-quartet") njengento eqhelekileyo kumculo).
I-Octet Strings kwieNdawo zeeNdawo ze-IP kunye neeNkqubo zoNxibelelwano
Ithenda yomtya we-octet ibhekisela kwingqokelela nayiphi na inani lee-octet ezihambelanayo. Amacandelo e-Octet aqhelekileyo atholakala kwi- intanethi ye-intanethi (IP) ejongene nayo , apho ii-bytes ze-IPv4 idilesi ziqukethe ii-octet ezi-4. Kwinqaku le-decimal-decimal, idilesi ye-IP ibonakala ngale ndlela:
[i-octet]. [i-octet]. [i-octet]. [i-octet]
Umzekelo:
192.168.0.1
Idilesi ye- IPv6 iqukethe ii-octet ezili-16 kunokuba ezine. Nangona uxwebhu lwe-IPv4 luhlukanisa nganye i-octet enye kunye nechashaza (.), Ukuphawula kwe-IPv6 kwahlula iibini zeeyiti kunye nekholoni, ngale ndlela:
[i-octet] [i-octet]: [i-octet] [octet] :::::: [i-octet] [i-octet]
Ii-ototi zingaphinde zibhekise kwiiyunithi zomntu ngokwazo ngaphakathi kwinqununu yechungechunge yechungechunge. Oonjiniyela benethiwekhi ngamanye amaxesha bahlula iiprotoksi njenge- octet yokugxila okanye ukubala kwe-octet . Iprotokto yokugxotha i-octet isekela iiyunithi zomyalezo ezizodwa (i-coded hard) ukulandelelana kweentsimbi (enye okanye ii-octet) ezifakiwe ukubonisa ukuphela komyalezo. Inkqubo yokubala ye-oct isekela iiyunithi zomyalezo kunye nobukhulu bazo (inani lee-octets) ezifakwe kwi-header protocol. Ezi zombini iinkqubo zivumela abafumana umyalezo ukuba baqaphele xa bagqibile ukucwangcisa idatha engenayo, nangona elowo lunamathuba alo ngokuxhomekeke ekusebenziseni kwenkqubo. (Indlela yesithathu, ebizwa ngokuba yintambo yokuxhuma , inomthumeli womyalezo unqumla umva wayo wokudibanisa ukubonisa ukuba akukho datha ethunyelwayo.)
I-octet
Kwiiphequluli zewebhu, i-MIME yohlobo lwesicelo / ukusasazwa kwe-octet kubhekisela kwifayili ebinariweyo ekhutshwa ngumncedisi phezu koxhumano lweHTTP . Abaxhasi beWebhu basebenzisa ii- octet imilayezo xa basebenzisana neentlobo ezininzi zeefayili zobunqamle kwaye xa bengenakukwazi ukuqaphela uhlobo lohlobo lwefayile okanye ukuba bathathe ifomathi ethile.
Abaphequluli bavame ukukhuthaza umsebenzisi ukuba achaze uhlobo lwefayile yomlambo we-octet ngokugcina ifayile kunye nokwandiswa kwegama lomgca.
