Inkathi yokudlulisela ngesivinini esikhulu iyeza - i-USB 4.0

Isingeniso

Ngo-1994, i-Intel ne-Microsoft basungula i-International Standardization Organization, ebizwa ngokuthi "i-USB-IF". Inhlangano ithuthukise uchungechunge lwezicaciso kanye nokucaciswa kwebhasi le-universal serial. Phakathi kwazo, izinga elithuthukisiwe mayelana nokushaja okusheshayo iphrothokholi ye-USB PD eyaziwa kakhulu, okwamanje engenye yezimiso ezisetshenziswa kakhulu zokushaja umphakathi, kanye nombiko wocwaningo mayelana nemvelo yezimboni ye-PD 3.1 ukhululwe ngaphambi kwenhloko eshajayo. inethiwekhi ikhiphe umbhalo omude, umuntu angaqonda lonke uchungechunge lwemboni ye-PD 3.1.

Ngaphezu kwalokho, i-USB-IF ithuthukise izinga lokudluliswa kwedatha, futhi yaqanjwa ngokuqondile i-USB #.0, ngemuva kokushintsha kwenguqulo yamanje, ukucaciswa kwakamuva kwe-USB yi-USB4, lesi sihloko sizongena ku-USB4 selokhu yakhululwa, emakethe. ukwakha i-ecology yezimboni.

Mayelana ne-USB4

Iphrothokholi yokudlulisa idatha ye-USB yakhululwa ngaphambi kwesikhathi kakhulu kune-USB PD, futhi i-USB1.0 yethulwa ngo-1996, unyaka wesithathu ngemva kokusungulwa kwe-USB-IF. Isizukulwane sokuqala sezinga le-USB, izinga lokudluliswa kwalo lingu-1.5Mbps kuphela, imininingwane yokuthuthukiswa kwezinguqulo zomlando ze-USB sicela ubheke ithebula elilandelayo:

NgoSepthemba 2019, i-USB4 yakhululwa ngokusemthethweni ngezinga eliphezulu lokudlulisela elingu-40Gbps, elifana neThunderbolt 3. I-USB4 inezincazelo ezimbili, ngokulandelana, i-USB4 40 enomkhawulokudonsa omkhulu ongu-40Gbps, i-USB4 20 enomkhawulokudonsa omkhulu ongu-20Gbps, futhi abathengi bayayidinga. ukubona ukuthi i-USB4 40 iyisixhumi esibonakalayo esigcwele igazi.

NgoSepthemba 2022, izinga le-USB4 2.0 ladalulwa kusengaphambili, izinga eliphezulu lakhushulelwa ku-80Gbps, ukwakheka kwedatha entsha kwamukelwa, futhi izinga lokushaja elisheshayo le-USB PD, isixhumi esibonakalayo se-USB Type-C nezinga lekhebula nakho kuzobuyekezwa ngokuhambisana.

Kungabonakala ukuthi ohlelweni lokubuyekezwa kwenguqulo, ukuguqulwa okukhulu kakhulu ukuthuthukiswa kwezinga lokudluliswa kwedatha, kusukela ku-1.5Mbps yokuqala kuya ekuvezweni kwamanje kwe-USB4 2.0 ifinyelele ku-80Gbps, ukwanda kwezikhathi ezingamashumi ezinkulungwane. Lolu shintsho lubangelwa ikakhulukazi ukuthuthukiswa kwesiteshi sokudlulisa idatha, kusukela ngo-2013, inguqulo yochungechunge lwe-USB3, ikhuphuke yaba ngamapheya angu-4 eziteshi ezihlukene, futhi ifakwe ukusebenza okungcono kwechweba le-USB-C, okwenza ukudluliswa kwedatha kube nokuthuthuka kwekhwalithi.

Njengamanje, kunemikhiqizo eminingi esebenzisa umsebenzi wokudluliswa kwedatha wesivinini esikhulu soxhumano lwe-USB-C, ikakhulukazi ezinye izisetshenziswa zesitoreji sangaphandle (njengamadrayivu e-solid-state anesivinini esiphezulu, izintambo zokudlulisela ngesivinini esiphezulu, kanye nezixhumanisi ezisetshenziswa ngokuqondile ezinye izincwadi zokubhalela eziphezulu).
