In tiknoolijiyada kombuyuutarka iyo shabakada, oct oct ah waxay u taagan tahay wax kasta oo 8- qadar ah . Sagaashooyinka kala duwan ee qiimaha xisaabaadka laga bilaabo 0 ilaa 255.
Ereyga " octet" ayaa sidoo kale loo adeegsadaa mawduucyo kale, sida waxqabadka muusikada, si loo tixraaco koox ka kooban sideed qof ama qaybo.
Sagaashinka iyo Baagadaha
Dhammaan qaababka casriga casriga ah waxay hirgeliyaan xajmiga oo ah 8-qiyaasood. Sagaashooyinka iyo baytalku waa isku mid. Sababtan awgeed, dadka qaarkood waxay isticmaalaan labada shuruudood. Taariikh ahaan, si kastaba ha ahaatee, kombiyuutarada ayaa taageera bytes kuwaas oo leh tiro kala duwan; octets iyo bytes macnaheedu waa waxyaabo kala duwan oo ku jira macnaha guud. Xirfadlayaasha shabakada waxay bilaabeen isticmaalka ereyga octet sannado badan kahor si ay u ilaaliyaan farqigaas.
Nidaamka kombiyuutarrada nidaamka kombiyuutaradu waxay inta badan isticmaalaan ereyga nibble marka loo eego tirada 4-qiyaasta (badh hal octet ama byte) halkii ay ugu yeeri laheyd "badhkiis" (ama "quartet", sida ay ku badan tahay muusikada).
Noocyada Octetka ee IP Adreesyada iyo Protocols Network
Ereyga ' octet string' waxaa loola jeedaa ururinta tirooyinka dhejiska ah ee la xiriira. Calaamadaha Octet waxaa badanaa laga helaa xariirka Internet-ka (IP) cinwaanka , kaas oo 4-da asbuuc ee cinwaanka IPv4 ka kooban yahay 4 octets. Tilmaame-tobanle-dhibcood, cinwaanka IP ayaa u muuqda sida soo socota:
[octet]. [octet]. [octet]. [octet]
Tusaale ahaan:
192.168.0.1
Cinwaanka IPv6 wuxuu ka kooban yahay 16 octets halkii afaraad. Halka ipodka ipv4 ay kala soocaan midkiiba hal mar oo leh dhibco (.), Farqiga IPv6 ayaa kala qaybiya labada xabbadood oo qashin ah, sida soo socota:
[octet] [octet]: [octet] [octet] [octet] :::::: [octet] [octet]
Sagaashiyadu sidoo kale waxay tixraaci karaan unugyada shakhsi ahaan shakhsi ahaaneed ee ku jira hogaanka taraafiga shabakadaha ama cagaha. Mashruucyada shabakadda waxay mararka qaarkood u kala saaraan nidaamyada sida walxaha octet ama tirinta octet . Qalabka qaboojiyaha octet-ka ah wuxuu taageersan yahay cutubyo farriin ah oo leh jaantusyo gaar ah oo adag (qoton-adag) oo xabbado ah (mid ama wax ka badan makiinada) loo geliyey si loo muujiyo dhamaadka farriinta. Qormo tirakoobka octet counting ayaa taageera unugyada fariimaha oo leh tiradooda (tirada octets) oo lagu qoondeeyey guddiga garsoorka. Labada dhinacba waxay u ogolaanayaan dadka fariinta inay go'aamiyaan marka ay dhammeeyaan falanqaynta xogta soo socota, inkastoo mid waliba leeyahay faa'iidadiisa ayadoo ku xiran isticmaalka loogu talagalay qawaaniinta. (Habka seddexaad, oo loo yaqaan " blasting connection" , miyuu farriin farriin ah joojiyaa dhammaadka xiriirka si loo muujiyo in aan xog kale loo dirin.)
Streaming Stream
Dareemaha webka, codsiga nooca MIME / octet-stream wuxuu loola jeedaa faylka ikhtiyaari ah ee lagu soo gudbiyo server ka badan xiriirka HTTP . Macaamiisha Webka waxay caadi ahaan isticmaalaan ilaha octet marka ay la shaqeynayaan noocyo badan oo faylasha ikhtiyaar ah iyo marka aysan awoodin inay aqoonsadaan nooca magaca faylka ama inay qaataan nooc kasta oo gaar ah.
Browsers ayaa inta badan ku faafiya cidda isticmaaleysa si ay u aqoonsadaan nooca faylka ah ee octet stream by kaydinta faylka leh foosto gaar ah oo gaar ah.
