Amazinga e-Universal Serial Bus (i-USB) ashintshile indlela esixhuma ngayo kumadivayisi ethu. Igebe phakathi kwe-USB 2.0 ne-USB 3.2 manje selibaluleke kakhulu. Lesi sihloko sibheka amandla nobuthakathaka bento ngayinye, nokuthi ibathinta kanjani abasebenzisi.

Okuthathwayo Okubalulekile

I-USB 2.0 ne-USB 3.2 ubuchwepheshe be-USB obuhlukile, obunokuthuthuka okukhulu kwejubane nokusebenza kahle.

Ukwazi umehluko omkhulu, njengezilinganiso zokudluliswa kwedatha nokulethwa kwamandla, kusiza ukuthuthukisa ukusebenza kwedivayisi nokuhambisana.

Ukukhetha izinga elilungile le-USB kuncike ezidingweni zakho nezidingo zedivayisi ukuze uthole ulwazi olungcono kakhulu.

Amazinga e-USB athuthukile ukuze ahambisane nesidingo sokudlulisa idatha ngokushesha kanye namadivayisi anamandla kakhulu.

Ukuhambisana nezibuyekezo ze-USB kusiza abasebenzisi ukuthi benze izinqumo ezingcono futhi bazijwayeze nobuchwepheshe obusha.

Ukuqonda Izinguqulo ze-USB

Ukuze siqonde umehluko phakathi kwe-USB 2.0 ne-USB 3.2, sidinga ukubheka ukuthi ubuchwepheshe be-USB bukhule kanjani. Kusukela ku-USB 2.0 evamile ukuya ku-USB 3.x entsha, isibuyekezo ngasinye senze izinguquko ezinkulu. Lezi zinguquko zihlanganisa ukudluliswa kwedatha okusheshayo, amandla engeziwe, nokusebenza okungcono.

I-USB 2.0

I-USB 2.0 yaphuma ngo-2000 futhi ngokushesha yaba inketho ephezulu yokuhambisa idatha nokuxhuma amadivayisi. Ingahambisa idatha ngenani elingu-480 Mbps, ukweqa okukhulu ukusuka ku-USB 1.1 endala. Namuhla, amadivayisi e-USB 2.0 asadumile ezintweni ezifana nokugcina amafayela nokushaja amafoni.

I-USB 3.0, 3.1, kanye ne-3.2

I-USB 3.0 yafika ngo-2008 futhi yaba yisinyathelo esikhulu. Ingahambisa idatha ku-5 Gbps, yethula "SuperSpeed" USB. Lokhu bekusho ukudluliswa kwedatha okusheshayo nokusebenzisa amandla okungcono. Kusukela lapho, i-USB 3.x ilokhu ibangcono, ne-USB 3.1 ne-3.2 enikeza isivinini esisheshayo nezici ezengeziwe.

I-USB 3.1 (eyaziwa nangokuthi i-SuperSpeed+) yaphuma ngo-2013. Iphinde kabili izinga ledatha yaba ngu-10 Gbps, okwenza kube ngcono emisebenzini edinga idatha eningi.

I-USB 3.2, ekhishwe ngo-2017, ilethe izinketho ezishesha nakakhulu. Ihlanganisa i-USB 3.2 Gen 1 (kufika ku-5 Gbps), i-USB 3.2 Gen 2 (kufika ku-10 Gbps), ne-USB 3.2 Gen 2x2 (kufika ku-20 Gbps). Lezi zivinini zihlangabezana nezidingo zamadivayisi nezinhlelo zokusebenza zanamuhla.

Izibuyekezo ku-USB 3.x ziguqule indlela esidlulisa ngayo idatha. Benza ukwabelana ngamafayela kube lula, ukwenza izipele ngokushesha, nokubuka amavidiyo bushelelezi. Ukwazi ngezinguqulo ezahlukene ze-USB kusiza abasebenzisi ukuthi bakhethe okungcono kakhulu kumadivayisi abo futhi bathole okuningi kuzo.

Umehluko Obalulekile Phakathi kwe-USB 2.0 ne-USB 3.2

Ukuqonda umehluko phakathi kwe-USB 2.0 ne-USB 3.2 kubalulekile. Lo mehluko uhlanganisa isivinini sokudluliswa kwedatha, izixhumi ezibonakalayo nokuhambisana, ukulethwa kwamandla, nombhalo wekhodi wedatha nokusebenza kahle.

Isivinini Sokudluliswa Kwedatha

I-USB 3.2 inokweqa okukhulu ngesivinini sokudlulisa idatha uma kuqhathaniswa ne-USB 2.0. I-USB 2.0 iphuma phezulu ngo-480 Mbps, kuyilapho i-USB 3.2 ingafinyelela kufika ku-20 Gbps. Lokhu kusho ukudluliswa kwamafayela okusheshayo, ukusakazwa kwevidiyo okushelelayo, nokwenza isipele sedatha esisheshayo.

Izixhumi Zomzimba Nokuhambisana

I-USB 2.0 isebenzisa izixhumi ze-USB-A ne-USB-B. I-USB 3.2 yethula i-USB-C, ebuyiseleka emuva futhi esekela ukulethwa kwamandla e-USB kanye ne-DisplayPort. Lokhu kwenza ukuxhuma amadivayisi kube lula futhi kube nezinto ezihlukahlukene.

Ukulethwa kwamandla

I-USB 3.2 inokulethwa kwamandla okungcono kune-USB 2.0. Ingadlulisela amandla afika ku-100W, anele ukushaja amakhompyutha aphathekayo nezinsiza ezinamandla amakhulu ngokuqondile ngoxhumo lwe-USB.

Umbhalo Wekhodi Wedatha kanye Nempumelelo

I-USB 3.2 futhi inombhalo wekhodi wedatha kanye nokusebenza kahle kune-USB 2.0. Isebenzisa isikimu sombhalo wekhodi esithuthukisiwe nobuchwepheshe bokusayina ukuze kudluliswe idatha ngokushesha kanye nokusebenzisa amandla amancane. Lokhu kusho ukusebenza okungcono nempilo yebhethri ende yamadivayisi axhunywe nge-USB 3.2.

Umehluko phakathi kwe-USB 2.0 ne-USB 3.2 ubonisa ukuthuthuka okukhulu kwisivinini sokudluliswa kwedatha, ukuxhumana ngokomzimba, ukulethwa kwamandla, nokusebenza kahle kwedatha. Nge-USB 3.2, abasebenzisi bathola ukuzizwisa okusheshayo, okuguquguqukayo lapho bexhuma amadivayisi.

Imithelela Esebenzayo Kubasebenzisi

Ukukhetha phakathi kwe-USB 2.0 ne-USB 3.2 kubalulekile kubasebenzisi bemishini ye-USB nama-peripherals. Ukwazi umehluko kusiza ukwenza izinqumo ezingcono. Lokhu kuqinisekisa ukusebenza okungcono kakhulu nokuphathwa kwamandla e-usb kwamahabhu e-usb nama-adaptha e-usb.

Ukuhambisana Kwedivayisi

Uma ukhetha phakathi kwe-USB 2.0 ne-USB 3.2, cabanga ngokuhambisana kwedivayisi. I-USB 3.2 inesixhumi esibonakalayo esingcono se-usb nezici zephrothokholi ye-usb. Kodwa, qiniseka ukuthi amadivayisi wakho we-usb kanye nama-usb peripherals asebenza nayo.

Amadivayisi amadala angase angazisekeli izici ezithuthukile ze-USB 3.2. Lokhu kusho ukuthi ungase udinge ukusebenzisa kokubili i-USB 2.0 ne-USB 3.2 ngezidingo ezahlukene.

Ukucatshangelwa kokusebenza

Ukukhetha phakathi kwe-USB 2.0 ne-USB 3.2 kuthinta indlela izinto ezisebenza kahle ngayo. Emisebenzini emikhulu efana nokuhlela ividiyo noma izipele zamafayela, isivinini esisheshayo se-USB 3.2 siyinhlanganisela enkulu. Kodwa, emisebenzini elula, umehluko ungase ungabi mkhulu.

Ngakho-ke, abasebenzisi bangakhetha i-USB 2.0 yemisebenzi yansuku zonke, noma ingasheshi kangako.

Izinzuzo Zokulethwa Kwamandla

Cabanga ngokuletha amandla lapho ukhetha phakathi kwe-USB 2.0 ne-USB 3.2. I-USB 3.2 inokuphathwa kwamandla we-usb okungcono. Lokhu kusho ukushaja okusheshayo namandla engeziwe kumadivayisi afana namakhompyutha aphathekayo namafoni.

Lokhu kuhle kubasebenzisi abadinga amandla okukhipha amandla e-usb athembekile futhi asebenzayo ngezidingo zabo zansuku zonke.

Isiphetho

Ukushintsha ukusuka ku-USB 2.0 kuye ku-USB 3.2 kulethe izinguquko ezinkulu. Lezi zinguquko zihlanganisa ukudluliswa kwedatha okusheshayo, amandla engeziwe, nokusebenza kahle kangcono. Ukusetshenziswa okukhulayo kwama-USB kuqhuba imibono emisha futhi kulolonge ikusasa. Kumabhizinisi nezimboni ezidinga amasistimu ekhompiyutha athembekile futhi angalawuleki, amakhompyutha we-rackmount aqinile nikeza ukuqina nokusebenza okudingekayo ukuze kuthuthukiswe izinketho zokuxhuma ezithuthukile njenge-USB 3.2.

Isivinini se-USB 3.2 esingafika ku-20Gbps silungele imisebenzi efana nokusakaza amavidiyo angu-4K nokuhambisa amafayela amakhulu. Futhi kwenza ukuxhuma amadivayisi kube lula. Uma uhlelo lwakho lokusebenza ludinga amasistimu asebenza kahle kakhulu, cabanga a i-PC eshumekiwe yezimboni engena fan. Futhi, i-USB 3.2 inikeza izinketho ezingcono zokushaja, ukuze ugcine amadivayisi akho eshajiwe noma yikuphi. Njengomholi umkhiqizi wamakhompyutha wezimboni, I-SINSMART TECH iqinisekisa ukuthi amasistimu ayo ahlonyiselwe ukuphatha lezi ntuthuko ngempumelelo.

I-USB 4.0 kanye nokukhuphuka kwezixhumi ze-USB-C kusethelwe ukuletha ukuthuthuka okwengeziwe. Ezimbonini ezidinga ukusetha okuqinile, a Ikhompyutha ye-4U ye-rackmount iyisinqumo esihle sokusekela amakhono e-USB esivinini esikhulu. Ngaphezu kwalokho, Ama-PC ashumekiwe e-Advantech zenzelwe ukuhlangabezana nezidingo zezinhlelo zokusebenza zezimboni ezithuthukile ezizuza kulokhu kuthuthukiswa kokuxhumana.

Njengoba ama-USB aqhubeka eba ngcono, singabheka phambili ekusebenzeni okusheshayo, ukuxhumana okwengeziwe, nokuhambisana iminyaka ezayo. Kulabo abafuna ukuhlanganisa ubuchwepheshe be-USB obusezingeni eliphezulu ezinhlelweni zabo, ngokubambisana nabanolwazi abakhiqizi be-PC abashumekiwe kuqinisekisa impumelelo yesikhathi eside. Lokhu kuzosisiza ukuthi sihambisane nempilo yethu yedijithali.
