Igihe cyo kohereza umuvuduko mwinshi kiraza - USB 4.0

Intangiriro

Mu 1994, Intel na Microsoft batangije umuryango mpuzamahanga wita ku bipimo ngenderwaho, bita "USB-NIBA". Ishirahamwe ryateguye urukurikirane rw'ibisobanuro n'ibisobanuro kuri bisi ikurikirana. Muri byo, igipimo cyatejwe imbere yishyurwa ryihuse ni protocole izwi cyane ya USB PD, kuri ubu ikaba ari imwe mu masezerano akoreshwa cyane mu kwishyuza rubanda, kandi raporo y’ubushakashatsi ku bidukikije by’inganda ya PD 3.1 yashyizwe ahagaragara mbere y’umuyobozi ushinzwe kwishyuza. umuyoboro watanze inyandiko ndende, umuntu arashobora kumva urwego rwose rwa PD 3.1.

Mubyongeyeho, USB-NIBA yashyizeho uburyo busanzwe bwo kohereza amakuru, kandi yitwa USB # .0, nyuma yuburyo bugezweho buhindutse, ibisobanuro biheruka bya USB ni USB4, iyi ngingo izacengera muri USB4 kuva yasohoka, ku isoko kubaka ibidukikije byinganda.

Hafi ya USB4

USB yohereza amakuru ya USB yasohotse hakiri kare cyane kurenza USB PD, naho USB1.0 yatangijwe mu 1996, umwaka wa gatatu nyuma ya USB-IF yashinzwe. Igisekuru cya mbere cya USB gisanzwe, igipimo cyacyo cyohereza ni 1.5Mbps gusa, ibisobanuro birambuye byiterambere rya verisiyo yamateka ya USB nyamuneka reba imbonerahamwe ikurikira:

Muri Nzeri 2019, USB4 yasohotse kumugaragaro ifite umuvuduko ntarengwa wa 40Gbps, kimwe na Thunderbolt 3. USB4 ifite ibisobanuro bibiri, kimwe, USB4 40 ifite umurongo mwinshi wa 40Gbps, USB4 20 ifite umurongo mwinshi wa 20Gbps, kandi abaguzi bakeneye kumenya ko USB4 40 ari intera yuzuye yamaraso.

Muri Nzeri 2022, ibipimo bya USB4 2.0 byagaragaye mbere, igipimo ntarengwa cyongerewe kugera kuri 80Gbps, hashyirwaho uburyo bushya bwo kubaka amakuru, kandi USB PD yihuta yo kwishyuza, USB Type-C interineti hamwe n’umugozi wa kabili nabyo byavugururwa icyarimwe.

Birashobora kugaragara ko mugikorwa cyo kuvugurura verisiyo, impinduka nini nukuzamura igipimo cyo kohereza amakuru, kuva 1.5Mbps yambere kugeza ubu USB4 2.0 igera kuri 80Gbps, ikiyongera inshuro ibihumbi icumi. Iri hinduka riterwa ahanini no kuzamura umuyoboro wogukwirakwiza amakuru, kuva 2013, verisiyo yuruhererekane ya USB3, yiyongereye kugera kuri joriji 4 yimiyoboro itandukanye, kandi ifite ibikoresho byiza bya USB-C, bituma ihererekanyamakuru rifite iterambere ryujuje ubuziranenge.

Kugeza ubu, hari ibicuruzwa byinshi bikoresha imikorere yihuta yo kohereza amakuru ya interineti ya USB-C, cyane cyane ibikoresho bimwe na bimwe bibikwa hanze (nka disiki yihuta-ikomeye ya disiki, imiyoboro yihuta yihuta, hamwe nintera ikoreshwa mu buryo butaziguye amakaye yo mu rwego rwo hejuru).
