2. Kusiyana Kwakukulu Pakati pa USB 2.0 ndi USB 3.2
3. Zomwe Zimakhudza Ogwiritsa Ntchito
4. Mapeto

Miyezo ya Universal Serial Bus (USB) yasintha momwe timalumikizirana ndi zida zathu. Kusiyana pakati pa USB 2.0 ndi USB 3.2 tsopano ndikofunika kwambiri. Nkhaniyi ikuyang'ana mphamvu ndi zofooka za aliyense, ndi momwe zimakhudzira ogwiritsa ntchito.

Zofunika Kwambiri

USB 2.0 ndi USB 3.2 ndi matekinoloje osiyanasiyana a USB, omwe ali ndi kusintha kwakukulu pa liwiro komanso kuchita bwino.

 Kudziwa kusiyana kwakukulu, monga mitengo yotumizira deta ndi kutumiza mphamvu, kumathandiza kukonza machitidwe a chipangizo ndi kugwirizana.

Kusankha mulingo woyenera wa USB zimatengera zosowa zanu ndi zofunikira pa chipangizo chanu kuti mumve bwino.

Miyezo ya USB yasintha kuti igwirizane ndi kufunikira kotumiza deta mwachangu komanso zida zamphamvu kwambiri.

Kusunga zosintha za USB kumathandizira ogwiritsa ntchito kupanga zisankho zabwino komanso kuzolowera umisiri watsopano.

Kumvetsetsa Mabaibulo a USB

Kuti timvetsetse kusiyana pakati pa USB 2.0 ndi USB 3.2, tiyenera kuyang'ana momwe ukadaulo wa USB wakulira. Kuchokera pa USB 2.0 wamba kupita ku USB 3.x yatsopano, zosintha zilizonse zasintha kwambiri. Zosinthazi zikuphatikiza kusamutsa deta mwachangu, mphamvu zambiri, komanso magwiridwe antchito abwino.

USB 2.0

USB 2.0 idatuluka mu 2000 ndipo mwachangu idakhala chisankho chapamwamba pakusuntha deta ndi zida zolumikizira. Ikhoza kusuntha deta pamlingo wa 480 Mbps, kulumpha kwakukulu kuchokera ku USB 1.1 yakale. Masiku ano, zida za USB 2.0 zimakondabe zinthu monga kusunga mafayilo ndi ma foni olipira.

USB 3.0, 3.1, ndi 3.2

USB 3.0 inafika mu 2008 ndipo inali sitepe yaikulu. Ikhoza kusuntha deta pa 5 Gbps, ndikuyambitsa "SuperSpeed" USB. Izi zikutanthauza kusamutsa deta mwachangu komanso kugwiritsa ntchito bwino mphamvu. Kuyambira nthawi imeneyo, USB 3.x yakhala ikukula bwino, ndi USB 3.1 ndi 3.2 yopereka kuthamanga kwambiri ndi zina zambiri.

USB 3.1 (yomwe imadziwikanso kuti SuperSpeed +) inatuluka mu 2013. Idachulukitsa chiwerengero cha deta ku 10 Gbps, ndikupangitsa kuti ikhale yabwino kwa ntchito zomwe zimafuna deta zambiri.

USB 3.2, yomwe idatulutsidwa mu 2017, idabweretsa zosankha zachangu. Zimaphatikizapo USB 3.2 Gen 1 (mpaka 5 Gbps), USB 3.2 Gen 2 (mpaka 10 Gbps), ndi USB 3.2 Gen 2x2 (mpaka 20 Gbps). Kuthamanga uku kumakwaniritsa zofunikira pazida zamakono ndi mapulogalamu.

Zosintha mu USB 3.x zasintha momwe timasamutsira deta. Amapangitsa kugawana mafayilo kukhala kosavuta, kusungitsa mwachangu, ndikuwonera makanema kukhala osalala. Kudziwa za mitundu yosiyanasiyana ya USB kumathandiza ogwiritsa ntchito kusankha zabwino kwambiri pazida zawo ndikupeza bwino.

Kusiyana Kwakukulu Pakati pa USB 2.0 ndi USB 3.2

Kumvetsetsa kusiyana pakati pa USB 2.0 ndi USB 3.2 ndikofunikira. Kusiyanaku kumakhudza kuthamanga kwa kusamutsa deta, zolumikizira zakuthupi ndi kuyanjana, kutumiza mphamvu, kusungitsa deta komanso kuchita bwino.

Kuthamanga kwa Data

USB 3.2 ili ndi kulumpha kwakukulu mu liwiro losamutsa deta poyerekeza ndi USB 2.0. USB 2.0 pamwamba pa 480 Mbps, pamene USB 3.2 imatha kufika ku 20 Gbps. Izi zikutanthauza kusamutsa mafayilo mwachangu, kusuntha kwamakanema mosavuta, ndikusunga zosunga zobwezeretsera mwachangu.

Zolumikizira Zathupi ndi Kugwirizana

USB 2.0 imagwiritsa ntchito zolumikizira za USB-A ndi USB-B. USB 3.2 imabweretsa USB-C, yomwe imatha kusinthanso ndikuthandizira USB Power Delivery ndi DisplayPort. Izi zimapangitsa kuti zida zolumikizira zikhale zosavuta komanso zosunthika.

Kutumiza Mphamvu

USB 3.2 ili ndi mphamvu yoperekera mphamvu kuposa USB 2.0. Itha kusamutsa mpaka 100W yamphamvu, yomwe ndi yokwanira kulipiritsa ma laputopu ndi zida zamphamvu kwambiri kudzera pa intaneti ya USB.

Kusindikiza kwa Data ndi Kuchita bwino

USB 3.2 ilinso ndi ma encoding abwinoko a data kuposa USB 2.0. Imagwiritsa ntchito chiwembu chapamwamba cha encoding ndi ukadaulo wamasigino kuti isamutsidwe mwachangu komanso kugwiritsa ntchito mphamvu zochepa. Izi zikutanthauza kuchita bwino komanso moyo wautali wa batri pazida zolumikizidwa kudzera pa USB 3.2.

Kusiyana pakati pa USB 2.0 ndi USB 3.2 kukuwonetsa kusintha kwakukulu pakuthamanga kwa data, kulumikizana kwakuthupi, kutumiza mphamvu, komanso kugwiritsa ntchito bwino deta. Ndi USB 3.2, ogwiritsa ntchito amapeza chidziwitso chachangu, chosunthika polumikiza zida.

Zotsatira Zothandiza Kwa Ogwiritsa Ntchito

Kusankha pakati pa USB 2.0 ndi USB 3.2 ndikofunikira kwa ogwiritsa ntchito zida za USB ndi zotumphukira. Kudziwa kusiyana kumathandizira kupanga zosankha zabwino. Izi zimatsimikizira magwiridwe antchito abwino kwambiri komanso kasamalidwe ka mphamvu za usb za ma usb hubs ndi ma adapter a usb.

Kugwirizana kwa Chipangizo

Mukasankha pakati pa USB 2.0 ndi USB 3.2, ganizirani za kugwirizana kwa chipangizocho. USB 3.2 ili ndi mawonekedwe abwinoko a usb ndi mawonekedwe a protocol ya usb. Koma, onetsetsani kuti zida zanu za usb ndi zotumphukira za usb zimagwiranso ntchito.

Zida zakale mwina sizingagwirizane ndi zida zapamwamba za USB 3.2. Izi zikutanthauza kuti mungafunike kugwiritsa ntchito USB 2.0 ndi USB 3.2 pazosowa zosiyanasiyana.

Malingaliro a Magwiridwe

Kusankha pakati pa USB 2.0 ndi USB 3.2 kumakhudza momwe zinthu zimagwirira ntchito. Pazochita zazikulu monga kusintha mavidiyo kapena zosunga zobwezeretsera mafayilo, kuthamanga kwa USB 3.2 ndikothandiza kwambiri. Koma, pa ntchito zosavuta, kusiyana sikungakhale kwakukulu.

Chifukwa chake, ogwiritsa ntchito amatha kusankha USB 2.0 pazantchito zatsiku ndi tsiku, ngakhale sizili mwachangu.

Ubwino Wopereka Mphamvu

Ganizirani za kutumiza mphamvu posankha pakati pa USB 2.0 ndi USB 3.2. USB 3.2 ili ndi kasamalidwe kabwino ka USB. Izi zikutanthauza kuyitanitsa mwachangu komanso mphamvu zambiri pazida monga ma laputopu ndi mafoni.

Izi ndizabwino kwa ogwiritsa ntchito omwe amafunikira mphamvu zodalirika komanso zogwira mtima za usb pazosowa zawo zatsiku ndi tsiku.

Mapeto

Kusintha kuchokera ku USB 2.0 kupita ku USB 3.2 kwabweretsa kusintha kwakukulu. Zosinthazi zimaphatikizapo kusamutsa deta mwachangu, mphamvu zambiri, komanso kuchita bwino. Kukula kogwiritsa ntchito ma USB kukuyendetsa malingaliro atsopano ndikupanga tsogolo. Kwa mabizinesi ndi mafakitale omwe amafunikira makina odalirika komanso owopsa apakompyuta, makompyuta olimba a rackmount perekani kulimba ndi magwiridwe antchito ofunikira kuti muthandizire njira zolumikizira zapamwamba monga USB 3.2.

Kuthamanga kwa USB 3.2 mpaka 20Gbps ndikwabwino pantchito ngati kutsitsa makanema a 4K ndikusuntha mafayilo akulu. Zimapangitsanso zida zolumikizira kukhala zosavuta. Ngati ntchito yanu ikufuna makina ophatikizika, ochita bwino kwambiri, ganizirani a PC yophatikizidwa ndi mafakitale opanda fan. Kuphatikiza apo, USB 3.2 imapereka njira zabwinoko zolipirira, kuti mutha kusunga zida zanu zili paliponse. Monga wotsogolera mafakitale opanga makompyuta, SINSMART TECH imawonetsetsa kuti makina ake ali ndi zida zogwirira ntchito bwino izi.

USB 4.0 ndi kukwera kwa zolumikizira za USB-C zakhazikitsidwa kuti zibweretse kuwongolera kowonjezereka. Kwa mafakitale omwe amafunikira kukhazikitsidwa kwamphamvu, a 4U rackmount kompyuta ndichisankho chabwino chothandizira kuthekera kothamanga kwa USB. Kuonjezera apo, Ma PC ophatikizidwa ndi Advantech amapangidwa kuti akwaniritse zosowa zamafakitale apamwamba omwe amapindula ndi kukweza kolumikizana uku.

Pamene ma USB akupitilirabe kuchita bwino, titha kuyembekezera kugwira ntchito mwachangu, kulumikizana kochulukirapo, komanso kugwirizana kwazaka zikubwerazi. Kwa iwo omwe akufuna kuphatikizira ukadaulo wapamwamba wa USB mumakina awo, kuyanjana ndi odziwa zambiri opanga PC ophatikizidwa zimatsimikizira kupambana kwa nthawi yayitali. Izi zitithandiza kupitirizabe ndi moyo wathu wa digito.
