USB 3, USB 3.1, Gen 1, Gen 2, USB Type-C: Zvose zvinorevei?
Mubvunzo: Ndeipi USB 3?
Chii chinonzi USB 3 uye ingashanda nemajeri angu akare USB 2 here?
Mhinduro:
USB 3 ndiyo yechitatu huru inonzi USB (Universal Serial Bus). Apo yakatanga kubudiswa, USB yakapa kuvandudza kwechokwadi kunoshamisa kwokuti nzira dzese dzakabatana sei nekombiyuta. Pamberi pacho, zviteshi zvemaseri uye zvakafanana zvaive zvakasikwa; chimwe nechimwe chaidiwa kunzwisisa zvakakwana kwezvinhu zvose zviripo uye kombiyuta inobata chigadziro kuitira kuti iite urongwa hwakakodzera.
Kunyange zvazvo pave pane zvimwe zvaiedza pakugadzira nyore nyore kushandiswa kwekombiyuta yemakombiyuta uye mhirizhonga, USB yaive yekutanga yekuti ibudirire kuva muzinga kune anenge makombiyuta, pasinei nemuiti.
USB 1.1 yakatanga bhora richigumburwa nokupa pirgi-play-play yakatsigira nokukurumidza kubva 1.5 Mbit / s kusvika 12 Mbits / s. USB 1.1 yakanga isiri yemadhimoni, asi yaive yakanyanya kukurumidza kukwanisa kugadzira mice, keyboards , modems, uye dzimwe nguva dzenguva-dzenguva.
USB 2 yakabvisa ante nekupa kusvika ku 480 Mbit / s. Kunyange zvazvo kukurumidza kwepamusoro kwaingoonekwa mu bursts, kwaive kuchinja kukuru. Mafambiro akaoma kunze aishandisa USB 2 akava nzira yakakurumbira yekuwedzera kuchengetedza. Shanduro yakagadziriswa uye yakasununguka yakaita kuti USB 2 isarudze zvakanaka kune dzimwe nzvimbo dzakasiyana-siyana, kusanganisira scanners, makamera, uye mavhidhiyo emamamera.
USB 3 inounza hutano hutsva hwekushanda, ine nzira itsva yekutsvaga data inonzi Super Speed, iyo inopa USB 3 chirevo chepamusoro chepamusoro che 5 Gbits / s.
Muchidimbu kushandiswa, nhanho yepamusoro ye 4 Gbits / s inotarisirwa, uye kuenderera mberi kwekuwedzerwa kwe 3.2 Gbits / s kunobudirira.
Izvi zvinokurumidza zvakakwana kudzivirira zvizhinji zvemazuva ano zvinotyisa kubva pakuzadza kuwirirana ne data. Uye yakakurumidza kuti ishandiswe neSATA - yakashata SSDs , kunyanya kana yako yakavhara kunze inotsigira UASP (USB Attached SCSI Protocol) .
Mhembera yekare yekuti zvinotya zvinotonhora zvishoma nezvishoma kupfuura zvepakati hazvisi zvekare nguva dzose.
Kukura kwekukurumidza hakusi kungovandudzika chete muIndaneti 3. Rinoshandisa nzira mbiri dzomunidirectional, imwe yokutumira uye imwe kugamuchira, saka iwe hauchafaniri kumirira bhazi rakachena usati watumira mashoko.
USB 3.1 Gen 1 inonyanya kufanana nezvakadai se USB 3. Iine matanho akafanana ekutsinhanisa (5 Gbits / s theoretical max), asi inogona kusanganiswa neConnector Type Type C (mashoko ari pasi apa) kupa zvinokwana 100 watts humwe simba, uye kukwanisa kuisa DisplayPort kana HDMI mavhidhiyo evhidhiyo.
USB 3.1 Gen 1 / USB Type-C ndiyo inonzi chikwata chekufambisa chinoshandiswa neMacBook 12-inch MacBook , iyo inopa kuwedzerwa kwekufambisa kwakafanana nehanzvadzi yeHTML 3.0, asi inowedzera kukwanisa kutarisa DisplayPort uye HDMI video, uyewo mano kushanda senzvimbo yekudzivirira yebheri reMacBook .
USB 3.1 Gen 2 inowedzera inoretical transfer rates ye USB 3.0 kusvika ku10 Gbits / s, iyo yakafanana nekufambisa mberi seyiyo yekutanga yeTypebolt. USB 3.1 Gen 2 inogona kusanganiswa nekombiki yeChina C-C itsva iyo inosanganisira kubhadhara mafaira, pamwe neVideoPort uye HDMI video.
USB Type-C (iyo inonziwo USB-C ) inogadzirwa nemichina yekambani USB inogona kushandiswa (asi haifaniri) kana USB 3.1 Gen 1 kana USB 3.1 Gen 2 tsanangudzo.
Ikoji yeC-USB-C uye tsanangudzo yekambo inobvumira kushandiswa kusinganzwisisiki, saka shati ye-USB-C inogona kusanganiswa mune chero mararamiro. Izvi zvinokonzera mutambo we USB-C mumusuo we USB-C yose yakawanda nyore.
Iyo inewo kukwanisa kutsigira dzimwe nzira dzedhara, zvichibvumira dhidha kusvika kuma10 Gbits / s, uyewo kukwanisa kutsigira DisplayPort uye HDMI video.
Pakupedzisira asi kwete, USB-C ine simba guru rekugadzirisa masimba (kusvika kune 100 watts), zvichibvumira USB-C chikwata kuti ishandise kusimba kana kutengesa makombiyuta akawanda ebhuku.
Kunyange zvazvo USB-C inogona kutsigira zvakakwirira dhiyo uye mavhidhiyo, hapana chikonzero chezvigadziri zvine majekesi e-USB-C kuti avashandise.
Somugumisiro, kana chigadziri chine chibatanidza che-USB-C, izvo hazvirevi kutaura kuti gwenga rinotsigira video, kana Thunderbolt-kufanana-famba. Kunyatsoziva iwe unofanirwa kuongorora zvakare, kuziva kana iri USB 3.1 Gen 1 kana USB 3 Gen 2 port, uye iyo inyanzvi iyo mudzidzi wekushandisa ari kushandisa.
USB 3 Architecture
USB 3 inoshandisa mami-bhasi system inobvumira USB 3 traffic uye USB 2 traffic kuti iite pamusoro pekanyoro panguva imwe chete. Izvi zvinoreva kuti kusiyana nemamwe mavambo e-USB, ayo akashanda nepamusoro-soro yejecha rinotonhora rakabatana, USB 3 inogona kuvhara pamwe chete kunyange kana USB 2 device ichibatanidzwa.
USB 3 inewo chinhu chinowanzoonekwa mumakombiriro eWorld and Ethernet: anotsanangurwa kugadzirisa-ku-kugadzirisa unyanzvi hwekutaurirana. Izvi zvinoita kuti iwe ushandise USB 3 ine makombiyuta akawanda uye nharaunda panguva imwechete. Uye zvakananga kuMacs uye OS X, USB 3 inofanira kukurumidzira chinangwa disk mode, nzira iyo Apple inoshandisa pakutumira data kubva kune akwegura Mac kusvika kune imwe itsva.
Compatibility
USB 3 yakagadzirwa kubva pakatanga kusvika kutsigira USB 2. Zvose zvinodiwa USB 2.x dzinofanira kushanda kana dzichibatanidza Mac inokwana USB 3 (kana chero kombiyuta yakagadzirirwa USB 3, nokuda kwenyaya iyi). Saizvozvowo, USB 3 pipisiti inogona kukwanisa kushanda ne USB 2 port, asi izvi zvishoma zvishoma, zvichienderana neshoko redu USB 3. Chero bedzi shanduro yacho isingabatsiri pane chimwe chekuvandudzwa kwakaitwa mu USB 3, inofanira kushanda ne USB 2 port.
Saka, zvakadini neHTML 1.1? Sezvo ndinogona kutaura, USB 3 tsanangudzo haisi mutsotsi we USB 1.1.
Asi dzakawanda zvinoputika, zvinosanganisira mabhiiyo emazuva ano uye mbeveve, i-USB 2 zvigadzirwa. Iwe ungangodaro unofanira kuchera zvakadzika mukati memakamuri ako kuti uwane USB 1.1 device.
USB 3 uye Mac yako
Apple yakasarudza nzira inofadza yekubatanidza USB 3 mune Mac Mac ayo. Munenge dzose mazera emakabva maMac anoita kushandisa USB 3.0 ports. Izvo chete ndeye 2015 MacBook, iyo inoshandisa USB 3.1 Gen 1 uye connector USB-C. Hapana maMic models emaoko akazvitsaurira USB 2 ports, sezvaunowanzowanzoona muPasite yeAna. Apple yakashandisa imwechete USB A connector vazhinji vedu tinoziva; musiyano ndewokuti USB 3 version yekubatanidza iyi ine zvipiti zvishanu zvinotsigira zvakakurisa kushanda kwe USB 3. Izvi zvinoreva kuti unofanira kushandisa USB 3 cabling kuti uwane USB 3 maitiro. Kana iwe ukashandisa dare rekare re USB 2 rawakawana mubhokisi riri mumakamuri ako, richashanda, asi pa USB 2 pakarepo.
Ikoji yeC USB-C inoshandiswa paMacBook 2015 inoda adapter dzemakambani kushanda nevakura ma USB 3.0 kana USB 2.0 madivayiri.
Iwe unogona kuona USB 3 cabling nekodhi yakaiswa mukati memukati. Inoumbwa netsamba "SS" neyechiratidzo chechi USB pedyo nemashoko. Nokuti ikozvino, unogona kungowana tsvuku dze USB 3, asi izvo zvinogona kuchinja, nokuti USB haigadziri rumwe ruvara.
USB 3 haisi yega yepamusoro-piritsi yeruzhinji iyo Apple inoshandisa. MaMacs akawanda ane mabhanji anotinha anokwanisa kushanda nokukurumidza kusvika kusvika 20 Gbps. 2016 MacBook Pro yakabudisa Thunderbolt 3 ports dzinotsigira kukurumidza 40 Gbps. Asi nokuda kwechimwe chikonzero, vadziri vadziri vasiri kupa mabhiriyuta akawanda, uye izvo zvavanopa zvinodhura.
Iye zvino, zvichida, USB 3 ndiyo inowanikwa nekutengesa-kutarisa kune-high-speed kunze kwekubatanidza.
