Mumakombiyuta uye munyanzvi yekombiki, an oct uye inomiririra chero upi zvake huwandu hwe8- bit . Octets iri mu mathematical kubva ku 0 kusvika 255.
Izwi rokuti octet rinoshandiswawo kune dzimwe mamiriro ezvinhu, zvakadai semimhanzi, kuratidza boka revanhu vasere kana zvikamu.
Octets vs. Bytes
Zvose zvemakombiyuta matsva anoita shanduro se 8-bit yakawandisa. Octets uye bytes zvakafanana kubva pane izvi. Nekuda kwechikonzero ichi, vamwe vanhu vanoshandisa mazwi maviri pamwe chete. Nhoroondo, zvisinei, makombiyuta akatsigira matambudziko ane nhamba dzakasiyana dzemakumbo; maoctet uye maete zvinoreva zvinhu zvakasiyana mumamiriro ezvinhu aya. Nyanzvi dzevashandi vakatanga kushandisa izwi rokuti octet makore akawanda apfuura kuti varambe vachiita izvi.
Makombiyuta masayenzi vanyanzvi vanowanzoshandisa izwi iri kubhururuka kana tichitaura kuine 4-bit (hafu yeectet kana kuti byte) panzvimbo yekuti iiti "hafu ye octet" (kana "quartet," sezvinojairika mumimhanzi).
Octet Strings mu IP Address uye Network Protocols
Izwi rokuti octet string rinoreva kuunganidzwa kwenhamba chero ipi zvayo yeoiti yakabatana. Gwaro reOctet rinonyanya kuwanika muIndaneti protocol (IP) inotaura , umo 4 bytes ye IPv4 kero ine 4 maitikiti. Muchidimbu-decimal decimal, kero ye IP inowanikwa seyizvi:
[octet]. [octet]. [octet]. [octet]
Semuyenzaniso:
192.168.0.1
An IPv6 kero ine maeti makumi matanhatu pane makumi mana. Nepo IPv4 nheyo inoparadzanisa octet imwe neimwe ine dot (.), IPv6 notation inoparadzanisa mapaundi eectet ane colon, sezvinotevera:
[octet] [octet]: [octet] [octet] :::::: [octet] [octet]
Irotesti inogonawo kutarisa kumunhu mumwe nomumwe zvikamu mukati me network protocol headers kana pasi. Dzimwe nyanzvi dzenjini dzimwe nguva dzinosarudza zvirongwa se octet stuffing kana octet kuverenga . An octet-stuffing protocol inotsigira mauniti emashoko ane maitiro akaoma (zvakaoma-coded) ezvigaro (rimwe kana ma octet) akaiswa kuti anzire kuguma kwemashoko. An octet kuverenga protocol inotsigira maunite emashoko nemasikisi awo (nhamba ye octets) yakakodhwa mukati memusoro weprotocol. Nzira mbiri idzi dzinobvumira vaparidzi vemu-sarudzo kuti vaone kana vapedzisa nekugadzirisa iyo inosvika data, kunyange zvazvo imwe neimwe ine zvigaro zvayo zvichienderana nechinangwa chekushandiswa kweprotocol. (Nzira yechitatu, iyo inonzi kubudiswa kwemashoko , ine mumiriri wemashoko anogumisa kuguma kwayo kwekubatanidza kuratidza kuti hapana deta iri kutumirwa.)
Octet Stream
Mukutsvaga kwewebhu, MIME type application / octet-stream inoreva bhainari yefaira inopihwa ne server pane hutano hweHTTP . Vashandi veWebhu vanowanzoshandisa mitsuko ye octet pavanenge vachishanda nemhando dzakawanda dzemafuta ebhinary uye kana vasingakwanisi kuziva rudzi rwezita rayo faira kana kuti kutora chero humwe huwandu humwe.
Browsers kazhinji inokurudzira mushumiri kuti aone faira yefaira ye octet mumugodhi nekuchengetedza faira rine rimwe zita rekuwedzera.
