Oge nnyefe ọsọ ọsọ na-abịa - USB 4.0
Okwu mmalite
Na 1994, Intel na Microsoft malitere International Standardization Organisation, nke akpọrọ "USB-IF". Nzukọ ahụ mepụtara usoro nkọwapụta na nkọwapụta maka ụgbọ ala serial zuru ụwa ọnụ. N'ime ha, ọkọlọtọ e mepụtara gburugburu ụgwọ ngwa ngwa bụ usoro USB PD a maara nke ọma, nke bụ ugbu a otu n'ime usoro ịgba ụgwọ ọha na eze na-emetụtakarị, na akụkọ nyocha banyere ụlọ ọrụ mmepụta ihe nke PD 3.1 ka ewepụtara n'ihu onye isi nchaji. netwọk ewepụtala ederede ogologo, mmadụ nwere ike ịghọta usoro ụlọ ọrụ niile nke PD 3.1.
Ke adianade do, USB-Ọ BỤRỤ na-emepụta ọkọlọtọ maka data nnyefe, na kpọmkwem aha ya bụ USB #.0, mgbe mgbanwe nke ugbu a version mgbanwe, ọhụrụ nkọwapụta nke USB bụ USB4, isiokwu a ga-devely n'ime USB4 kemgbe a tọhapụrụ ya, na ahịa. iji wulite gburugburu ebe obibi mmepụta ihe.
Ihe gbasara USB4
E wepụtara usoro mbufe data USB tupu oge eruo karịa USB PD, ewebata USB1.0 na 1996, afọ nke atọ ka emebere USB-IF. Ọgbọ mbụ nke ọkọlọtọ USB, ọnụego nnyefe ya bụ naanị 1.5Mbps, nkọwa nke mmepe nke ụdị akụkọ ihe mere eme USB biko lee tebụl na-esonụ:
Na Septemba 2019, ewepụtara USB4 n'ihu ọha yana ọnụego nnyefe kacha nke 40Gbps, dị ka Thunderbolt 3. USB4 nwere nkọwapụta abụọ, n'otu n'otu, USB4 40 nwere bandwidth kachasị nke 40Gbps, USB4 20 nwere oke bandwidth nke 20Gbps, yana ndị ahịa chọrọ. imata na USB4 40 bụ ihe nhụcha ọbara zuru oke.
Na Septemba 2022, ekpughere ọkọlọtọ USB4 2.0 tupu oge eruo, abawanyele ọnụego kachasị elu ruo 80Gbps, anabatara ụkpụrụ ụlọ data ọhụrụ, yana ọkọlọtọ chaja ngwa ngwa USB PD, interface USB Type-C na ọkọlọtọ USB ga-emelitekwa ọnụ.
Enwere ike ịhụ na n'ime usoro mmelite mbipute, mgbanwe kachasị ukwuu bụ mmụba nke ọnụego nnyefe data, site na 1.5Mbps mbụ ruo na mkpughe nke USB4 2.0 dị ugbu a ruru 80Gbps, mmụba nke iri puku kwuru iri puku ugboro. Mgbanwe a bụ n'ihi nkwalite nke ọwa nnyefe data, ebe ọ bụ na 2013, ụdị usoro USB3, na-abawanye ruo 4 ụzọ abụọ nke ọwa dị iche iche, ma kwadebere ya na ọdụ ụgbọ USB-C ka mma, na-eme ka nnyefe data nwere ọganihu qualitative.
Ka ọ dị ugbu a, enwere ọtụtụ ngwaahịa na-etinye ọrụ nnyefe data dị elu nke interface USB-C, ọkachasị ụfọdụ ngwaọrụ nchekwa mpụga (dị ka draịva steeti siri ike na-agba ọsọ, eriri nnyefe ọsọ ọsọ, na interfaces ejiri ozugbo na ya. ụfọdụ akwụkwọ ndetu dị elu).
