Ndezvipi musiyano uripo pakati peUSB 3.1 Gen 1uyeGen 2?
USB 3.1 Gen 1uyeGen 2: Kutsanangura Musiyano Wakakosha Pakati Pemitemo Miviri
Paunenge uchitenga zvishandiso zvekuchengetera zvinhu zvekunze, nzvimbo dzekuisa madoki, kana malaptop, mhando dzema USB interfaces dzinowanzo vhiringidza, kunyanya kana mazwi akadai seUSB 3.1 Gen 1uyeGen 2dzinowanikwa kakawanda. Kunyangwe zvese zviri zviviri zviri zveUSB 3.1Mumhuri yakajairika, kune misiyano yakakura mukushanda uye mashandisirwo anoitwa. Chinyorwa chino chichaongorora musiyano mukuru uripo pakati pezvinhu zviviri izvi kuti chikubatsire kusarudza zvine ruzivo rwakakura.
Kusiyana Kwekukurumidza: Musiyano Mukuru
Kumhanya kukuru kwekutamisa kwedzidziso kweUSB 3.1 Gen 1(pakutanga yaizivikanwa seUSB 3.0) inosvika 5 Gbps (inenge 625 MB/s). Kumhanya uku kwakakwana kushandiswa kwezuva nezuva, zvakaita sekubatanidza mbeva, makiyibhodhi, maprinta, kana kutamisa mafaira madiki akadai semagwaro nemimhanzi.
USB 3.1 Gen 2, kune rumwe rutivi, inowedzera kaviri muganho wepamusoro uyu kusvika10 Gbps(inenge 1250 MB/s). Izvi zvinoreva kuti kana uchitumira mafaira makuru, akadai semavhidhiyo e4K, mapikicha eRAW format, kana mapakeji makuru ekuisa mitambo, nguva inodiwa ichaderedzwa zvakanyanya. Semuenzaniso, kutumira faira remafirimu re50GB 4K, Gen 2 inogona kuchengetedza hafu yenguva zvichienzaniswa neGen 1.
Nheyo dzehunyanzvi uye Zvirongwa zvekunyora makodhi
Musiyano wekumhanya uri mukushanda zvakanaka kwezvirongwa zvekunyora makodhi.USB 3.1 Gen 1inoshandisa chirongwa chekodhi che8b/10b, zvichireva kuti 8 chete pa10 bits inotumirwa ndiyo data chaiyo, ine kushanda kweinenge 80%. Saka, bandwidth chaiyo inoshanda ye5 Gbps raw rate inenge 4 Gbps.
USB 3.1 Gen 2Kuvandudzwa kwe128b/132b coding scheme inoshanda zviri nani, zvichiwedzera kushanda zvakanaka kusvika pa97%, zvichibvumira 10 Gbps raw rate kupa bandwidth inoshanda nekukurumidza. Kuvandudzwa uku hakungobatsiri kumhanya chete asiwo kunoderedza nguva yekutumira.
Kubatana Kwemuviri uye Kuenderana
Zvakakosha kuziva kuti zveseUSB 3.1 Gen 1uyeGen 2inogona kushandisa mhando dzakafanana dzechimiro, dzinosanganisira:
Type-A (yakajairika rectangular interface)
Type-B (inonyanya kushandiswa mumaprinta nezvimwe zvishandiso)
Type-C (inogona kudzoserwa oval interface)
USB 3.1 A kuenda kuMicro B(inowanzoshandiswa mumadhiraivha ekunze uye mune mamwe madivayisi ekare eAndroid)
Zvakakosha kucherechedza kutiUSB Type-Cchimiro che interface, kwete chiyero chekumhanya. Chimiro che Type-C chinogona kutsigiraUSB 3.1 Gen 1, Gen 2, kana kunyange Thunderbolt 3 protocol. Saka, kumhanya kwekutumira hakugone kutsanangurwa chete nechimiro che interface. Semuenzaniso, aUSB C kuenda kuUSB ACable inogona kunge iine kumhanya chaiko kunogumira pamatanho ekupindirana kwenhare kumativi ese uye kunaka kwecable, iyo inogona kunge iri Gen 1's 5 Gbps kana Gen 2's 10 Gbps.
Kugona Kuburitsa Simba
Panyaya yemagetsi, pasi peUSB 3.1 Gen 1standard, interface inogona kupa simba rinosvika 4.5W (5V/0.9A). Iyo Gen 2 interface, kana ikashandiswa ne USB Power Delivery (PD) protocol, inogona kutsigira simba rinosvika 100W (20V/5A), iro rinokwana kuchaja malaptop mazhinji uye kupa simba ma peripherals anoshanda zvakanyanya. Zvinofanira kucherechedzwa kuti kana uchishandisa aTambo ye USB 3.1 A kuenda ku Micro BKuti ubatanidze zvishandiso, kugona kwemagetsi kunowanzo ganhwa neMicro B port specification, uye simba rinowanzo derera.
Mazano Ekushandisa Anoshanda
SarudzaUSB 3.1 Gen 1: Yakakodzera kubatanidza zvinhu zvemagetsi (makiyibhodhi, mbeva, maprinta), kutamisa magwaro ezuva nezuva, kana senzira yekuchaja nharembozha. Kune vashandisi vane bhajeti shoma kana kuti vanoda zvishoma, zvishandiso zvinoenderana neGen 1 zvinopa kukosha kuri nani. Semuenzaniso, kugadzira hard drive yekare yenharembozha ine standardTambo ye USB 3.1 A kuenda ku Micro B, kumhanya kweGen 1 kunowanzo kukwana.
SarudzaUSB 3.1 Gen 2: Kana uchida kutamisa mafaira makuru nguva nenguva (akadai sekugadzirisa mavhidhiyo, kugadzira mitambo), kubatanidza madhiraivha ekunze anomhanya zvakanyanya (SSDs), kana kutarisira kugadzirisa zvinodiwa zvekuchaja laptop uye kutumira data netambo imwe chete, Gen 2 isarudzo iri nani. Kunyanya kune vashandisi vemalaptop matsva, aUSB C 3.1 kuenda ku USB A wayakana adapta inotsigira Gen 2 inogona kubatanidza zvishandiso zvinobudirira kune zvekushandisa zvechinyakare kana mahub ane huwandu hwakawanda hweType-A interfaces, uku ichivimbisa kutumira data nekukurumidza.
Gwaro reKuziva uye Kutenga
Nekuda kwekuvhiringidzika pakudomwa kwemazita emusika, ndapota cherechedza zvinotevera pakutenga:
Vamwe vagadziri vanogona kuisa mazita avo paUSB 3.1 Gen 1se "USB 3.0"kana kuti" SuperSpeed USB"
USB 3.1 Gen 2inogona kunzi "SuperSpeed"USB 10 Gbps"
Maitiro eUSB achangoburwa atumidzwa zita idzva:USB 3.1 Gen 1ikozvino yaiswa muchikamu che "USB 3.2 Gen 1", uyeUSB 3.1 Gen 2ikozvino "USB 3.2 Gen 2"
Kana uchitengaUSB C 3.1 kuenda kuUSB Aor Tambo ye USB 3.1 A kuenda ku Micro Bs, iva nechokwadi chekuti tsananguro yechigadzirwa inoratidza zvakajeka kana ichitsigira Gen 1 (5 Gbps) kana Gen 2 (10 Gbps) kudzivirira matambudziko ekushanda nekuda kwetambo.
Kuti uve nechokwadi chekuti unowana mashandiro aunoda, nyatsoongorora zvinodiwa zvechigadzirwa pane kungovimba nechimiro chemuchina chete. Kana zvichidikanwa, tarisa magwaro ehunyanzvi epamutemo.
Pfupiso
Sarudzo pakatiUSB 3.1 Gen 1uye Gen 2 inonyanya kusanganisira kuwana chiyero pakati pekumhanya, mutengo, uye zvinodiwa chaizvo. Ingave iri itsva here?USB C 3.1 kuenda kuUSB Amhinduro yekushandura kana yekareUSB 3.1 A kuenda kuMICRO BNzira yekubatanidza, Gen 1 inopa mhinduro yakavimbika uye isingadhuri yemashandisirwo ezuva nezuva, nepo Gen 2 ichivhura nzira inokurumidza kune vashandisi vane hunyanzvi uye zviitiko zvinoshanda zvakanyanya. Sezvo kudiwa kwekumhanya kwekutumira data kubva kumidziyo kuri kuramba kuchikura, kunzwisisa misiyano iyi kuchakubatsira kuita sarudzo dzehunyanzvi dzetekinoroji muhupenyu hwako hwedhijitari.
Mune ramangwana, nekushandiswa kwakapararira kwe USB4 standard, kumhanya kwekutumira data kuchawedzera kusvika ku40 Gbps uye kuchabatanidza Thunderbolt 3 protocol. Asi kusvika panguva iyoyo,USB 3.1 Gen 1uye Gen 2 zvichagara kwenguva yakareba, zvichishandira mamiriro akasiyana ekushandisa uye mapoka evashandisi zvichiteerana.
