Isizukulwane esikhulu esilandelayo se-USB (i-Universal Serial Bus) kuzoba yi-USB 4, noma inguqulo ye-USB4, futhi izonikela ngezithuthukisi eziningi, njengokuxhaswa kweThunderbolt 3 nemifudlana efinyelela kuma-40 Gbps.
Okwamanje, le 2019 i izinhlobo ezintsha (neziningana) ze-USB 3.x efinyelela ku-20 Gbps. ukudluliswa kwedatha. Okwakamuva, inguqulo ye-USB 3.2 Gen 2 × 2 yethule yona le 2019, njenge-USB 4.
I-USB 4 yethulwe ngoMashi 2019 ngeso lengqondo lokuthi le protocol izoba yini futhi ngaphandle kokumemezela usuku oluzotholakala ngalo.. Kodwa-ke, amahemuhemu abonakala ekhomba ngo-2020 besivele sizobona amadivayisi ane-USB 4 kuzixhumi ze-USB-C. Vele, lapho kuphela u-2020, ngakho-ke kufanele silinde isikhathi esingaphezu konyaka ukuwabona emakethe.
I-Apple iyisinyathelo esisodwa phambili kulokhu. Izixhumi ze-USB-C kumamodeli ayo amasha we-Mac yiThunderbolt 3, ngakho-ke isekela kuze kufike ku-40 Gbps. ukudluliswa kwedatha namanye amadivayisi ahambisanayo. Ngaphandle kwalokho, futhiIsixhumi esifanayo se-USB-C kuma-Macs naso siyi-USB 3.1 Gen 2 futhi sisekela kufika ku-10 Gbps.
Izixhumi zamanje ze-Mac zingahle zihambisane ne-USB 4 njengoba le nguqulo ye-USB izosuselwa kuThunderbolt 3 futhi izosebenzisa izixhumi zohlobo lwe-USB-C.
I-USB 4 nobuchwepheshe bayo bangenza ukuthi 2020 unyaka lapho, ekugcineni, i-USB-C inwetshwa njengesixhumi esithandwayo samadivayisi amasha futhi hhayi kuphela imikhiqizo ye-Apple (engekho kumaMacs kuphela, kepha nakwiPad Pro entsha eyisebenzisa njengesixhumi kuphela) namanye amadivayisi ngamanye avela kweminye imikhiqizo, ikakhulukazi kuma-mobiles aphezulu.
I-Apple ne-Intel benze umsebenzi omningi kuThundebolt futhi kubonakala sengathi i-USB ihloselwe ukuwela ezinzuzweni ezinikezwa yilobu buchwepheshe ngaphezu kwale yamanje. Kepha, okwamanje, kufanele silinde.
