USB 3, USB 3.1, Gen 1, Gen 2, USB Mtundu C: Kodi zonsezi zikutanthauza chiyani?
Funso: Kodi USB 3 ndi chiyani?
Kodi USB 3 ndi iti yomwe ikugwira ntchito ndi zipangizo zanga zakale za USB?
Yankho:
USB 3 ndiyoyikulu yachitatu ya USB (Universal Serial Bus). Pamene unayambitsidwa, USB inapanga kusintha kochititsa chidwi momwe zipangizo zimagwirizanirana ndi kompyuta. Poyambirira, madoko oyandikana ndi ofanana ndi amodzi; aliyense amafunikira kumvetsetsa mwatsatanetsatane za chipangizo ndi makompyuta omwe akugwiritsira ntchito chipangizochi kuti athetse bwino kugwirizana.
Ngakhale pakhala kuyesayesa kwina popanga njira yosavuta yogwiritsira ntchito makompyuta ndi zipangizo, USB inali yoyamba kuti ikhale yoyenera pafupifupi pafupifupi makompyuta aliyense, mosasamala kanthu kwa wopanga.
USB 1.1 inayamba mpira ukugudubuza popereka pulogalamu yowonjezera yomwe imathandizira mwamsanga kuchokera ku 1.5 Mbit / s mpaka 12 Mbiti / s. USB 1.1 sanali chiwanda chofulumira, koma inali yofulumira kwambiri kuthana ndi mbewa, makibodi , modem, ndi zina zothamanga mofulumira.
USB 2 inapanganso ante pogwiritsa ntchito mpaka 480 Mbit / s. Ngakhale kuti kuthamanga kwapamwamba kunkawoneka pang'onopang'ono, kunali kusintha kwakukulu. Ma drive ovuta kunja pogwiritsira ntchito USB 2 anakhala njira yowonjezera yowonjezera yosungirako. Kupititsa patsogolo kwake mofulumira ndi kuthamanga kwapangidwe kunapangitsa USB 2 kusankha bwino kwa zinyama zambiri, kuphatikizapo kujambulira, makamera, ndi mavidiyo.
USB 3 imabweretsa mgwirizano watsopano, ndi njira yatsopano yosamutsira deta yotchedwa Super Speed, yomwe imapatsa USB 3 maulendo apamwamba kwambiri a 5 Gbits / s.
Pakagwiritsidwe ntchito, liwiro la 4 Gbits / s likuyembekezeredwa, ndipo mlingo wopitirira wa 3.2 Gbits / s ukutheka.
Icho ndichangu mwamsanga kuti muteteze zambiri zamakono zovuta lero kuti muzitha kugwirizana ndi deta. Ndipo mwamsanga mwakugwiritsidwa ntchito ndi ma SSD ambiri omwe ali pansi , makamaka ngati chipinda chanu chakunja chikuthandizira UASP (USB Attached SCSI Protocol) .
Zolemba zakale zomwe zoyendetsa kunja zimapita pang'onopang'ono kusiyana ndi internals sizinayambe nthawizonse.
Kuthamanga kofulumira sikuli kokha kusintha kwa USB 3. Kumagwiritsa ntchito njira ziwiri zosagwirizana ndi deta, imodzi yofalitsa ndi yovomerezeka, kotero kuti musayembekezere basi yobisika musanatumize uthenga.
USB 3.1 Gen 1 imakhala ndi makhalidwe ofanana ndi USB 3. Ali ndi malire ofanana (5 Gbits / soretical max), koma akhoza kuphatikizidwa ndi chojambulira cha mtundu wa C (USB pansipa) kuti apereke kwa Watt 100 mphamvu yowonjezera, komanso kuthekera kuyika zithunzi za DisplayPort kapena mavidiyo a HDMI.
USB 3.1 Gen 1 / USB Mtundu wa C ndizofotokozera phukusi zomwe zimagwiritsidwa ntchito ndi MacBook 12-inch 2015 , zomwe zimapereka maulendo othamanga ngati USB port, koma zimatha kuwonetsa Video DisplayPort ndi HDMI , komanso mphamvu kuti ukhale ngati gombe lozaza la bateri la MacBook .
USB 3.1 Gen 2 imaphatikizapo chiwerengero cha kusintha kwake kwa USB 3.0 mpaka 10 Gbits / s, zomwe ndizofanana kuthamanga mofanana ndi mafotokozedwe oyambirira a Thunderbolt. USB 3.1 Gen 2 ikhoza kuphatikizidwa ndi mawonekedwe atsopano a USB Type-C kuphatikizapo kubwezeretsa mphamvu, komanso zithunzi za DisplayPort ndi HDMI.
Mtundu wa C-USB (womwe umatchedwanso USB-C ) ndi mawonekedwe a mawonekedwe a phukusi la USB lomwe lingagwiritsidwe ntchito (koma silofunika) ndi USB 3.1 Gen 1 kapena USB 3.1 Gen 2 mafotokozedwe.
Makanema a USB-C ndi chingwe amaloleza kugwirizanitsa, kotero chingwe cha USB-C chingagwirizanitsidwe kumalo alionse. Izi zimapangitsa kudula makina a USB-C mu doko la USB-C mosavuta kwambiri.
Iyenso ili ndi mphamvu zothandizira njira zambiri zothandizira, zomwe zimapatsa deta kufika 10 Gbits / s, komanso kumatha kuwonetsera DisplayPort ndi video ya HDMI.
Chosakanikirana, USB-C ili ndi mphamvu zogwiritsira ntchito mphamvu (mpaka 100 watts), kulola kuti chipika cha USB-C chigwiritsidwe ntchito kapena kuika makompyuta ambiri a notebook.
Ngakhale USB-C ikhoza kuthandizira maulendo apamwamba ndi mavidiyo, palibe chofunikira kwa zipangizo zomwe zimagwiritsidwa ntchito ndi USB-C kuti zigwiritse ntchito.
Zotsatira zake, ngati chipangizo chiri ndi chojambulira cha USB-C, sizikutanthauza kuti gombe likugwiritsira ntchito kanema, kapena kuthamanga kwa Mkokomo. Kuti mudziwe bwino, muyenera kufufuza, kuti mudziwe ngati ndi USB 3.1 Gen 1 kapena USB 3 Gen 2 port, ndipo zomwe zimagwiritsidwa ntchito ndi wopanga chipangizo.
Zojambula za USB 3
USB 3 imagwiritsa ntchito njira zambiri zamabasi zomwe zimalola USB 3 magalimoto ndi USB 2 traffic kuti agwire pa cabling yomweyo. Izi zikutanthauza kuti mosiyana ndi USB yam'mbuyo, yomwe imagwira ntchito mofulumira kwambiri ya chipangizo chochedwa kwambiri, USB 3 imatha kupota ngakhale ngakhale chipangizo cha USB 2 chikugwirizanitsidwa.
USB 3 imakhalanso ndi machitidwe a FireWire ndi Ethernet. Mphamvu imeneyi imakulolani kugwiritsa ntchito USB 3 ndi makompyuta ambiri ndi padera nthawi yomweyo. Ndipo zowonjezera ma Macs ndi OS X, USB 3 iyenera kuyendetsa chithunzithunzi cha disk mode, njira imene apulo amagwiritsira ntchito pamene akusamutsa deta kuchokera ku Mac yakale kupita ku yatsopano.
Kugwirizana
USB 3 inalengedwa kuchokera pa chiyambi kuti ithandizire USB 2. Zipangizo zonse za USB 2.x ziyenera kugwira ntchito pamene zogwirizana ndi Mac omwe ali ndi USB 3 (kapena kompyuta iliyonse yokhala ndi USB 3, pa nkhaniyi). Mofananamo, pulogalamu ya USB 3 iyenera kugwira ntchito ndi doko la USB 2, koma izi ndizovuta, chifukwa zimadalira mtundu wa USB 3. Malinga ngati chipangizocho sichidalira njira imodzi yokha yopangidwa mu USB 3, iyenera kugwira ntchito ndi doko la USB 2.
Nanga bwanji USB 1.1? Malingana ndi momwe ndingathere, mafotokozedwe a USB 3 satchula thandizo la USB 1.1.
Koma zowonjezereka zambiri, kuphatikizapo makibodi amakono ndi mbewa, ndi zipangizo za USB 2. Mwinamwake muyenera kukumba mozama mkati mwanu kuti mupeze chipangizo cha USB 1.1.
USB 3 ndi Mac
Apple inasankha njira yodabwitsa yosakaniza USB 3 mu Mac yake yopereka. Pafupifupi mitundu yonse ya Mac-generation yomwe ikuchitika tsopano ikugwiritsa ntchito ma CD 2.0. Chokhacho ndicho MacBook 2015, chomwe chimagwiritsa ntchito USB 3.1 Gen 1 ndi chojambulira cha USB-C. Zitsanzo zamakono zamakono zamakono a Mac zakhala zopereka ma doko 2 a USB, monga momwe mumakonda kupezera pa PC. Apple imagwiritsa ntchito USB yomweyi. Ambirife timadziwa bwino; kusiyana kwake ndikuti pulogalamu ya USB 3 ya chojambulira ichi ili ndi mapiritsi ena asanu omwe amathandiza kwambiri kuthamanga kwa USB 3. Izi zikutanthauza kuti muyenera kugwiritsa ntchito makina a USB 3 kuti mupeze machitidwe a USB 3. Ngati mumagwiritsa ntchito chingwe chakale cha USB 2 chimene mwapeza mu bokosi lanu, chigwira ntchito, koma pa USB 2.
Chipika cha USB-C chomwe chimagwiritsidwa ntchito pa MacBook ya 2015 chimafuna adapitala zamakina kuti agwire ntchito ndi zipangizo zakale za USB 3.0 kapena USB 2.0.
Mukhoza kuzindikira makina osakaniza a USB 3 ndi chizindikiro chophatikizidwa mu chingwe. Zili ndi makalata "SS" okhala ndi chizindikiro cha USB pafupi ndi mawuwo. Pakali pano, mungapeze zingwe zakuda za USB 3 zokha, koma izi zingasinthe, chifukwa chiwerengero cha USB sichifuna mtundu wina.
USB 3 siyi yokha yomwe imagwiritsa ntchito pulogalamu yomwe Apple amagwiritsira ntchito. Ma Macs ambiri ali ndi mabingu omwe angagwire ntchito mofulumira kufika 20 Gbps. 2016 MacBook Pro inachititsa kuti maulendo atatu a Thunderbolt athandizidwe mofulumira pa 40 Gbps. Koma pazifukwa zina, opanga akadalibe kupereka zowonjezera zamtunda, ndipo zomwe iwo amapereka ndi okwera mtengo kwambiri.
Pakalipano, USB 3 ndiyo njira yowonjezera mtengo wa maulendo apamwamba kwambiri.
