USB 3 yog qhov thib peb loj iteration ntawm Universal Serial Bus (USB) tus qauv. Thaum USB tau tshaj tawm thawj zaug, nws muab kev txhim kho tseem ceeb hauv koj li cas txuas cov khoom siv peripheral rau koj lub computer. Nrog rau cov chaw nres nkoj serial thiab kev sib txuas ua ke uas ua ntej USB, koj yuav tsum nkag siab ob qho tib si peripheral thiab lub khoos phis tawj koj tau txuas rau. USB yog thawj hom chaw nres nkoj los ua tus qauv ntawm cov khoos phis tawj tsis hais cov chaw tsim khoom.

Cov ntaub ntawv hauv kab lus no siv rau Apple li hauv qab no:

  • iMac 2012 thiab tom qab
  • iMac Pro 2017 thiab tom qab
  • iPad Pro 2016 thiab tom qab (nrog rau Lightning-to-USB adapter)
  • Mac mini 2012 thiab tom qab
  • MacBook Air 2012 thiab tom qab
  • MacBook Pro 2012 thiab tom qab
  • Mac Pro 2013 thiab tom qab

Keeb Kwm ntawm USB

Cia peb saib cov keeb kwm ntawm tus qauv USB no.

USB 1.x

USB 1.1 muab kev txuas txuas thiab ua si uas txhawb kev nrawm ntawm 1.5 megabits ib ob (Mbps) txog 12 Mbps. USB 1.1 tsis yog dab ceev, tab sis nws tau nrawm txaus los tswj cov nas, keyboards, modems, thiab lwm yam khoom siv hluav taws xob qis.

USB 2

USB 2 muaj peev xwm ceev txog 480 Mbps. Sab saum toj ceev tshwm sim hauv tawg, tab sis tiam thib ob yog ib qho kev txhim kho tseem ceeb. Sab nraud hard drives tsim rau USB 2 los ua ib txoj hauv kev nrov ntxiv rau koj Mac. Qhov kev txhim kho ceev thiab bandwidth no ua rau USB 2 yog qhov kev xaiv zoo rau lwm yam khoom siv sab nraud, nrog rau cov scanners, koob yees duab, thiab cov koob yees duab video.

USB 3.x

Tam sim no thib peb ntawm tus qauv USB tau tshaj tawm tshiab "Image"About This Mac" hauv macOS" id=mntl-sc-block-image_1-0-1 /> alt="

  • USB 3 Architecture

    USB 3 siv ntau lub tsheb npav uas tso cai rau USB 3 tsheb thiab USB 2 tsheb khiav mus rau hauv lub cabling ib txhij. Yog li, tsis zoo li yav dhau los versions ntawm USB, uas ua haujlwm ntawm qhov ceev tshaj plaws ntawm cov cuab yeej txuas nrog qeeb tshaj plaws, USB 3 tuaj yeem zip nrog txawm tias thaum USB 2 ntaus ntawv txuas nrog.

    USB 3 kuj muaj qhov tshwj xeeb hauv FireWire thiab Ethernet systems: lub peev xwm sib txuas lus tus tswv-rau-tus tswv tsev. Los ntawm qhov muaj peev xwm no, koj tuaj yeem siv USB 3 nrog ntau lub khoos phis tawj thiab cov khoom siv sab nraud tib lub sijhawm. Thiab tshwj xeeb rau Macs, USB 3 yuav tsum ua kom lub hom phiaj Disk, ib txoj kev Apple koj siv thaum hloov cov ntaub ntawv los ntawm Mac qub mus rau ib qho tshiab.

    kab hauv qab

    USB 3 tau tsim los txhawb USB 2, thiab. Txhua USB 2.x pab kiag li lawm yuav tsum ua hauj lwm thaum koj txuas lawv mus rau ib tug Mac nruab nrog ib tug USB 3 chaw nres nkoj. Ib yam li ntawd, USB 3 peripheral ntaus ntawv yuav tsum ua haujlwm nrog USB 2 chaw nres nkoj, tab sis qhov tseeb nws nyob ntawm hom USB 3 ntaus ntawv.

    USB 3 thiab koj lub cuab yeej Apple

    Txhua tus qauv Mac tom qab 2012 muaj USB 3.0 chaw nres nkoj. Qhov kev zam tsuas yog 2015 MacBook, uas siv USB 3.1 Gen 1 thiab USB-C txuas. Tsis muaj Mac qauv tau mob siab rau USB 2 chaw nres nkoj vim Apple tsim nws tus kheej version ntawm tus qauv ntawd, hloov, hu ua Lightening. Apple siv tus qauv USB Hom-A txuas, tab sis USB 3 version ntawm lub connector muaj tsib tus pins ntxiv uas txhawb nqa kev ua haujlwm siab ntawm USB 3. Yog li, koj yuav tsum siv USB 3 cabling kom tau txais USB 3 kev ua tau zoo. Yog tias koj siv USB 2 qub qub uas koj pom hauv lub thawv hauv koj lub txee dai khaub ncaws, nws yuav ua haujlwm tab sis ntawm USB 2 nrawm.

    USB 3 cabling muaj lub logo USB thiab "SS." Ntau yam uas tsis yog Apple USB 3.0 cables muaj lub xov tooj xiav; Apple tsis siv cov qauv xim no hauv nws tus kheej cables.

    Nyob rau xyoo 2016, Apple tau yuam nws cov kiv cua nrog ib qho kev thov ntxiv rau iPad: USB 3.0 ua haujlwm. Lub iPad Pro (thib peb tiam) muaj USB-C chaw nres nkoj uas koj tuaj yeem siv los txuas lub cuab yeej ncaj qha mus rau AC phab ntsa qhov hluav taws xob lossis lub computer-Mac lossis Windows-based PC-uas muaj Thunderbolt lossis USB-C chaw nres nkoj rau them. Koj tuaj yeem siv qhov chaw nres nkoj no los txuas cov khoom siv peripheral, xws li saib, rau koj lub iPad Pro. (Nyob ntawm cov chaw nres nkoj ntawm koj lub computer, koj yuav xav tau lub adapter.)
