Ngazi Umehluko ophawuleka kakhulu phakathi kwe-USB 2.0 ne-USB 3.0 Izici zabo ezibaluleke kakhulu.
i USB isifinyezo se I-Universal Serial Bus. Kuyi-interface esetshenziselwa ukuxhuma amadivaysi e-peripheral afana nalokhu: I-الماوس وikhibhodi وiphrinta وama-hard drive kukhompyutha yakho.
ukhululiwe USB 2.0 ngonyaka 2000 Inguqulo edume kakhulu ye-. USB esetshenziswayo kuze kube manje.
ukhululiwe USB 3.0 ngonyaka 2008 Uthatha kancane kancane.
njengalokho USB 2.0 و USB 3.0 Banesethi eyingqayizivele yezici. Ngakho, ngalesi sihloko, sizofunda mayelana Wonke umehluko phakathi kwe-USB 2.0 و USB 3.0.
Umehluko phakathi kwe-USB 2.0 ne-USB 3.0
Emigqeni elandelayo, sizofunda mayelana Umehluko phakathi kwe-USB 2.0 ne-USB 3.0 Ngakho, ake siqale.
1. Ukubukeka komzimba
- izixhumi I-USB 2.0 emnyama ngaphakathi , Ngenkathi I-USB 3.0 iluhlaza okwesibhakabhaka ngaphakathi.
- I-USB 2.0 inesixhumi esinezintambo ezi-4 , Ngenkathi I-USB 3.0 inesixhumi esinezintambo ezi-9.
Ngakho, izixhumi USB 3.0 mkhulu kunomqhubi USB 2.0. Kanjalo, ukuze kuhlaliswe izintambo ezengeziwe.
Ngakho-ke, Izixhumi ze-USB 3.0 azikwazi ukusetshenziswa nezimbobo ze-USB 2.0.
2. Isivinini sokudlulisa
- finyelela Isivinini sokudlulisa se-USB 2.0 Ngaso 480 Mbps.
- finyelela Isivinini sokudlulisa se-USB 3.0 Ngaso 4.8 Gbps.
Ngakho-ke I-USB 3.0 ishesha izikhathi ezingu-10 kune-USB 2.0.
3. Ukuhambisana emuva
amachweba USB 3.0 Iyahambisana emuva. Ngakho, idivayisi ingaxhunywa USB 2.0 ichweba USB 3.0.
Nokho, lapho uxhuma idivayisi USB 3.0 ichweba USB 2.0 , isivinini sokudlulisa idatha sizokhawulelwa kusivinini USB 2.0 , okumayelana 480 Mbps.
4. Ukuphathwa kwamandla
- I-USB 2.0 iletha amandla afinyelela ku-500mA amandla emicabangweni yakhe.
- I-USB 3.0 iletha amandla afinyelela ku-900mA amandla emicabangweni yakhe.
Lokhu kubangela ukwanda kwenani eliphelele lokulethwa kwamandla ukusuka ku-2.5W kuya ku-4.5W ku-5V.
Ngakho-ke, Amadivayisi e-USB 3.0 angashajwa ngokushesha uma exhunywe kumachweba we-USB 3.0. njenge I-USB 3.0 inikeza ukuphathwa kwamandla okuphumelelayo futhi ikhuphule ukulethwa kwamandla. Angakwazi futhi Yonga amandla ngokunqamula ukunikezwa kumadivayisi angasebenzi.
5. Umkhawulokudonsa
- USB 2.0 Ukuxhumana kwendlela eyodwa, okusho ukuthi idatha ithunyelwa futhi yamukelwe ngendlela efanayo.
Ngakho, ... USB 2.0 Ukuthumela idatha noma ukwamukela idatha kuphela ngesikhathi esithile , kodwa hhayi kokubili. - USB 3.0 Iwukuxhumana kwendlela eyodwa, okusho ukuthi isebenzisa izindlela ezimbili ezihlukene zedatha yendlela eyodwa. Enye iwukuthumela idatha kanti enye iwukwamukela idatha.
Ngakho-ke, I-USB 3.0 inomkhawulokudonsa omningi kune-USB 2.0.
6. Izintambo ze-USB
- Izintambo ze-USB 3.0 zingasetshenziswa ukuxhuma kumachweba we-USB 2.0 futhi ngokuphambene nalokho. Kodwa amadivaysi e-USB 3.0 adinga kuphela izintambo ezingu-3.0.
Ngakho-ke, kubalulekile ukuthi ufanise ikhebula le-USB nenguqulo yembobo ye-USB. - ingafinyelela Ubude bekhebula le-USB 2.0 ukuya ku-5m ngenkathi phezulu Ubude bekhebula le-USB 3.0 ukuya ku-3m Vele.
7. Inani
Lungiselela Amadivaysi e-USB 2.0 ashibhe kakhulu kunamadivayisi e-USB 3.0. Lokhu kungenxa yezici ezithuthukile ezinikezayo USB 3.0 , ulahlekile USB 2.0.
Noma kunjalo, Imishini ye-USB 3.0 ihlinzeka ngenani lemali.
Izinhlobo ze-USB
- I-USB 1.0: Isekela kufika kumatheminali angu-127 ngenani Ukudluliswa kwedatha kufika ku-12Mbps.
- I-USB 2.0: Yethulwa okokuqala ngo-2000 futhi yaziwa ngokuthi I-Hi-Speed USB. Isekela amadivayisi namakhebuli USB 1.
- USB 3.0 أو I-SuperSpeed USB: Kuyinguqulo ethuthukisiwe ye USB 2 Yethulwa okokuqala ngo-2008.
- I-USB 3.1: Inguqulo yakamuva ye-. yethuliwe USB , waziwa ngo I-SuperSpeed + , okokuqala ngqa ngo-2014.
- Imbobo yohlobo C ye-USB: Kuyipulaki ehlehliswayo enamaphini angu-24 eyethulwa ngesikhathi esifanayo USB 3.1 Cishe.
Isiphetho:
Lawa kwakungabanye Umehluko obonakalayo phakathi kwe-USB 2.0 ne-USB 3.0. Njengoba sishilo emigqeni edlule, izinzuzo i-USB 3.0 enazo ngaphezu kwalezo ze-USB 2.0. Ngakho, sincoma ukukhetha i-USB 3.0 phezu kwe-USB 2.0.
Futhi, i-USB 3.0 iyahambisana emuva, ngakho-ke, asikho isidingo sokuthi usebenzise noma yiliphi ithuluzi elikhethekile ukuxhuma idivayisi ye-USB 2.0 embotsheni ye-USB 3.0, ngokuphambene nalokho.
