Uyini umehluko phakathiI-USB 3.1 Gen 1futhiIsizukulwane sesi-2?
I-USB 3.1 Gen 1futhiIsizukulwane sesi-2: Ukwembula Umehluko Obalulekile Phakathi Kwezindinganiso Ezimbili
Uma uthenga amadivayisi esitoreji sangaphandle, iziteshi zokufaka ama-docking, noma ama-laptop, izinhlobo ze-USB interfaces zingase zidideke, ikakhulukazi uma amagama anjengokuthiI-USB 3.1 Gen 1futhiIsizukulwane sesi-2kuvame ukuvela. Nakuba zombili zingabelunguI-USB 3.1Uma ubheka umndeni ojwayelekile, kunomehluko omkhulu ekusebenzeni nasekusetshenzisweni okungokoqobo. Lesi sihloko sizohlola umehluko obalulekile phakathi kwalezi zincazelo ezimbili ukuze sikusize wenze ukukhetha okunolwazi oluthe xaxa.
Umehluko Wesivinini: Umehluko Oyinhloko
Isivinini sokudlulisa esiphezulu kakhulu esicatshangelwayoI-USB 3.1 Gen 1(ekuqaleni kwakwaziwa ngokuthiI-USB 3.0) kufika ku-5 Gbps (cishe u-625 MB/s). Lesi sivinini sanele ukusetshenziswa kwansuku zonke, njengokuxhuma amagundane, amakhibhodi, amaphrinta, noma ukudlulisa amafayela amancane afana namadokhumenti nomculo.
I-USB 3.1 Gen 2Ngakolunye uhlangothi, kuphinda kabili lo mkhawulo ophezulu ku-10 Gbps(cishe i-1250 MB/s). Lokhu kusho ukuthi uma udlulisela amafayela amakhulu, njengamavidiyo e-4K, izithombe zefomethi ye-RAW, noma amaphakheji amakhulu okufaka imidlalo, isikhathi esidingekayo sizoncishiswa kakhulu. Isibonelo, ukudlulisa ifayela le-movie le-4K elingu-50GB, i-Gen 2 ingonga cishe ingxenye yesikhathi uma kuqhathaniswa ne-Gen 1.
Isisekelo Sobuchwepheshe kanye Nezinhlelo Zokubhala Amakhodi
Umehluko wesivinini usekusebenzeni kahle kwezinhlelo zokubhala amakhodi.I-USB 3.1 Gen 1isebenzisa uhlelo lokubhala ikhodi lwe-8b/10b, okusho ukuthi ama-bits angu-8 kuphela kwangu-10 adlulisiwe ayidatha yangempela, esebenza kahle cishe ngo-80%. Ngakho-ke, i-bandwidth yangempela esebenzayo yesilinganiso sokungahluzwa se-5 Gbps cishe ingama-4 Gbps.
I-USB 3.1 Gen 2ukuthuthukiswa kube uhlelo lokubhala ikhodi lwe-128b/132b olusebenza kahle kakhulu, okwandisa ukusebenza kahle kube cishe ngu-97%, okuvumela izinga lokusetshenziswa kwe-10 Gbps ukuthi linikeze i-bandwidth esebenza kahle cishe ngesivinini esigcwele. Lokhu kuthuthukiswa akugcini nje ngokukhulisa isivinini kodwa futhi kunciphisa ukubambezeleka kokudlulisa.
Ukuxhumana Okubonakalayo Nokuhambisana
Kubalulekile ukuqaphela ukuthi kokubiliI-USB 3.1 Gen 1futhiIsizukulwane sesi-2angasebenzisa izinhlobo ezifanayo zesibonisi esibonakalayo, okuhlanganisa:
Uhlobo-A (isikhombikubona esijwayelekile esingunxande)
Uhlobo-B (oluvame ukusetshenziswa kumaphrinta nakwamanye amadivayisi)
Uhlobo-C (isikhombikubona se-oval esiguqukayo)
I-USB 3.1 A kuya ku-Micro B(ivame ukusetshenziswa kuma-hard drive angaphandle nakwamanye amadivayisi amadala e-Android)
Kubaluleke kakhulu ukuqaphela ukuthiUhlobo C lwe-USBkuyisimo sesixhumi esibonakalayo, hhayi indinganiso yesivinini. Isixhumi esibonakalayo sohlobo C singase sisekeleI-USB 3.1 Gen 1, uGen 2, noma ngisho nephrothokholi yeThunderbolt 3. Ngakho-ke, ijubane lokudlulisela alikwazi ukunqunywa kuphela ngesimo sesixhumi esibonakalayo. Isibonelo, i-I-USB C kuya ku-USB Aikhebula lingase libe nesivinini sangempela esinqunyelwe yizindinganiso ze-interface kuzo zombili izinhlangothi kanye nekhwalithi yekhebula, okungaba yi-5 Gbps ye-Gen 1 noma i-10 Gbps ye-Gen 2.
Amandla Okukhipha Amandla
Ngokuphathelene nokunikezwa kukagesi, ngaphansiI-USB 3.1 Gen 1ejwayelekile, isixhumi singanikeza amandla afinyelela ku-4.5W (5V/0.9A). Isixhumi se-Gen 2, uma sisetshenziswa nephrothokholi ye-USB Power Delivery (PD), singasekela amandla afinyelela ku-100W (20V/5A), okwanele ukushaja ama-laptop amaningi nokunika amandla ama-peripherals asebenza kahle kakhulu. Kufanele kuqashelwe ukuthi uma usebenzisa i-Ikhebula le-USB 3.1 A kuya ku-Micro BUkuxhuma amadivayisi, amandla okunikezwa kwamandla ngokuvamile anqunyelwe yincazelo yembobo ye-Micro B, futhi amandla ngokuvamile aphansi.
Iziphakamiso Zokusebenzisa Eziwusizo
KhethaI-USB 3.1 Gen 1: Ifanele ukuxhumanisa izinto ezijwayelekile (amakhibhodi, amagundane, amaphrinta), ukudlulisa amadokhumenti ansuku zonke, noma njengesixhumi sokushaja ifoni ephathekayo. Kubasebenzisi abanesabelomali esilinganiselwe noma izidingo eziphansi, amadivayisi asekelwe ku-Gen 1 anikeza inani elingcono lemali. Isibonelo, ukuhlomisa i-hard drive yeselula endala nge-standardIkhebula le-USB 3.1 A kuya ku-Micro B, ijubane leGen 1 livame ukwanele.
KhethaI-USB 3.1 Gen 2Uma udinga njalo ukudlulisa amafayela amakhulu (njengokuhlela ividiyo, ukuthuthukiswa komdlalo), ukuxhuma ama-drive angaphandle aqinile (ama-SSD) asheshayo, noma unethemba lokuxazulula izidingo zokushaja i-laptop kanye nokudluliswa kwedatha ngekhebula elilodwa, i-Gen 2 iyisinqumo esingcono. Ikakhulukazi kubasebenzisi bama-laptop amasha,Ikhebula le-USB C 3.1 kuya ku-USB Anoma i-adaptha esekela i-Gen 2 ingaxhuma kahle amadivayisi kuma-peripheral noma kuma-hub endabuko anenani elikhulu lama-interface e-Type-A, ngenkathi iqinisekisa ukudluliswa kwedatha okusheshayo.
Umhlahlandlela Wokuhlonza Nokuthenga
Ngenxa yokudideka ekuqanjweni kwemakethe, sicela uqaphele okulandelayo uma uthenga:
Abanye abakhiqizi bangase babhale amalebulaI-USB 3.1 Gen 1njengoba "I-USB 3.0"noma" i-SuperSpeed USB"
I-USB 3.1 Gen 2kungabizwa ngokuthi "i-SuperSpeedI-USB 10 Gbps"
Izindinganiso zakamuva ze-USB ziqanjwe kabusha:I-USB 3.1 Gen 1manje sekuhlukaniswe ngokuthi "I-USB 3.2 Gen 1", futhiI-USB 3.1 Gen 2manje "I-USB 3.2 Gen 2"
Uma uthengaI-USB C 3.1 kuya ku-USB Aor Ikhebula le-USB 3.1 A kuya ku-Micro Bs, qiniseka ukuthi incazelo yomkhiqizo ikhombisa ngokucacile ukuthi iyayisekela i-Gen 1 (5 Gbps) noma i-Gen 2 (10 Gbps) ukuze kugwenywe izithiyo zokusebenza ngenxa yekhebula.
Ukuqinisekisa ukuthi uthola ukusebenza okufiselekayo, hlola ngokucophelela imininingwane yomkhiqizo kunokuthembela kuphela ekwakhekeni kwesixhumi esibonakalayo. Uma kudingeka, bheka imibhalo yobuchwepheshe esemthethweni.
Isifinyezo
Ukukhetha phakathiI-USB 3.1 Gen 1futhi i-Gen 2 ihilela ukuthola ibhalansi phakathi kwesivinini, intengo, nezidingo zangempela. Kungakhathaliseki ukuthi kuyinto entsha noma chaI-USB C 3.1 kuya ku-USB Aikhambi lokuguqula noma i-classicI-USB 3.1 A kuya ku-MICRO BIndlela yokuxhuma, i-Gen 1 inikeza ikhambi elithembekile nelingabizi kakhulu lezinhlelo zokusebenza zansuku zonke, kuyilapho i-Gen 2 ivula indlela esheshayo kubasebenzisi abangochwepheshe kanye nezimo zokusebenza okuphezulu. Njengoba isidingo sejubane lokudlulisa idatha kusuka kumadivayisi siqhubeka sikhula, ukuqonda lo mehluko kuzokusiza ukuthi wenze izinqumo zobuchwepheshe ezihlakaniphile empilweni yakho yedijithali.
Esikhathini esizayo, ngokwamukelwa kabanzi kwendinganiso ye-USB4, isivinini sokudlulisa idatha sizokhula sifinyelele ku-40 Gbps futhi sihlanganise iphrothokholi ye-Thunderbolt 3. Kodwa kuze kube yileso sikhathi,I-USB 3.1 Gen 1kanye ne-Gen 2 zizohlala isikhathi eside, zikhonza izimo ezahlukene zohlelo lokusebenza kanye namaqembu abasebenzisi ngokulandelana.
