Qhov txawv ntawmUSB 3.1 Gen 1thiabGen 2?
USB 3.1 Gen 1thiabGen 2Kev Tshawb Pom Qhov Txawv Tseem Ceeb Ntawm Ob Tus Qauv
Thaum yuav khoom siv cia khoom sab nraud, chaw nres tsheb, lossis laptops, cov hom USB interfaces feem ntau tuaj yeem ua rau tsis meej pem, tshwj xeeb tshaj yog thaum cov lus zoo liUSB 3.1 Gen 1thiabGen 2feem ntau tuaj txog. Txawm hais tias lawv ob leeg koom nrogUSB 3.1tsev neeg tus qauv, muaj qhov sib txawv tseem ceeb hauv kev ua tau zoo thiab kev siv tau. Tsab xov xwm no yuav tshawb nrhiav qhov sib txawv tseem ceeb ntawm ob qho lus qhia no los pab koj xaiv tau zoo dua.
Qhov Sib Txawv Ceev: Qhov Sib Txawv Tseem Ceeb
Qhov siab tshaj plaws theoretical transfer speed ntawmUSB 3.1 Gen 1(thawj zaug hu uaUSB 3.0) yog txog li 5 Gbps (kwv yees li 625 MB/s). Qhov ceev no txaus rau kev siv txhua hnub, xws li txuas nas, keyboards, tshuab luam ntawv, lossis xa cov ntaub ntawv me me xws li cov ntaub ntawv thiab suab paj nruag.
USB 3.1 Gen 2, ntawm qhov tod tes, ob npaug qhov kev txwv sab saud no rau10 Gbps(kwv yees li 1250 MB/s). Qhov no txhais tau tias thaum xa cov ntaub ntawv loj, xws li cov yeeb yaj kiab 4K, cov duab hom RAW, lossis cov pob khoom teeb tsa kev ua si loj, lub sijhawm xav tau yuav raug txo qis heev. Piv txwv li, xa cov ntaub ntawv yeeb yaj kiab 50GB 4K, Gen 2 tuaj yeem txuag tau yuav luag ib nrab ntawm lub sijhawm piv rau Gen 1.
Kev Tsim Kho thiab Cov Qauv Coding
Qhov sib txawv ntawm qhov ceev yog nyob rau hauv qhov ua tau zoo ntawm cov qauv coding.USB 3.1 Gen 1siv txoj kev cai coding 8b/10b, txhais tau tias tsuas yog 8 ntawm txhua 10 bits xa mus yog cov ntaub ntawv tiag tiag, nrog rau kev ua haujlwm zoo li ntawm 80%. Yog li ntawd, qhov bandwidth ua haujlwm tiag tiag ntawm 5 Gbps raw rate yog kwv yees li 4 Gbps.
USB 3.1 Gen 2hloov kho dua tshiab mus rau qhov kev siv 128b/132b coding scheme zoo dua, ua kom qhov ua tau zoo dua txog li 97%, uas ua rau 10 Gbps raw rate muab bandwidth yuav luag tag nrho. Qhov kev txhim kho no tsis yog tsuas yog ua kom ceev dua xwb tab sis kuj txo qhov latency ntawm kev xa xov.
Kev Sib Txuas Lus Lub Cev thiab Kev Sib Xws
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ob qho tib siUSB 3.1 Gen 1thiabGen 2siv tau tib hom interface lub cev, suav nrog:
Hom-A (tus qauv sib txuas ntawm lub duab plaub fab)
Hom-B (feem ntau siv rau hauv cov tshuab luam ntawv thiab lwm yam khoom siv)
Hom-C (qhov sib txuas rov qab tau)
USB 3.1 A mus rau Micro B(feem ntau siv rau hauv cov hard drive sab nraud thiab qee cov khoom siv Android qub)
Nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum nco ntsoov tiasUSB Hom-Cyog ib daim duab interface, tsis yog tus qauv ceev. Ib qho Type-C interface yuav txhawb nqaUSB 3.1 Gen 1, Gen 2, lossis txawm tias Thunderbolt 3 protocol. Yog li ntawd, qhov ceev ntawm kev xa xov tsis tuaj yeem txiav txim siab los ntawm cov duab interface xwb. Piv txwv li, ibUSB C rau USB Atej zaum yuav muaj qhov ceev tiag tiag txwv los ntawm cov qauv ntawm cov interfaces ntawm ob qho kawg thiab qhov zoo ntawm lub cable, uas yuav yog Gen 1's 5 Gbps lossis Gen 2's 10 Gbps.
Lub peev xwm tso zis hluav taws xob
Nyob rau hauv cov nqe lus ntawm kev muab hluav taws xob, nyob rau hauv lubUSB 3.1 Gen 1tus qauv, lub interface tuaj yeem muab siab tshaj plaws ntawm 4.5W (5V / 0.9A) ntawm lub zog. Lub Gen 2 interface, thaum siv nrog USB Power Delivery (PD) protocol, tuaj yeem txhawb nqa txog li 100W (20V / 5A) ntawm lub zog muab hluav taws xob, uas txaus los them feem ntau cov laptops thiab lub zog ua haujlwm siab. Nws yuav tsum tau sau tseg tias thaum siv aUSB 3.1 A rau Micro B cableTxhawm rau txuas cov khoom siv, lub peev xwm muab hluav taws xob feem ntau raug txwv los ntawm Micro B chaw nres nkoj specification, thiab lub zog feem ntau qis dua.
Cov Lus Qhia Txog Kev Siv Tau
XaivUSB 3.1 Gen 1Nws yog qhov tsim nyog rau kev txuas cov khoom siv dav dav (keyboards, nas, tshuab luam ntawv), xa cov ntaub ntawv txhua hnub, lossis ua lub xov tooj ntawm tes them interface. Rau cov neeg siv uas muaj peev nyiaj tsawg lossis tsis muaj kev xav tau, cov khoom siv raws li Gen 1 muab tus nqi zoo dua rau cov nyiaj. Piv txwv li, nruab ib lub hard drive qub nrog tus qauvUSB 3.1 A rau Micro B cable, qhov ceev ntawm Gen 1 feem ntau txaus.
XaivUSB 3.1 Gen 2Yog tias koj xav tau hloov cov ntaub ntawv loj (xws li kev kho video, kev tsim kev ua si), txuas cov khoom siv sab nraud ceev ceev (SSDs), lossis vam tias yuav daws tau qhov xav tau ntawm kev them lub laptop thiab kev xa cov ntaub ntawv nrog ib txoj hlua, Gen 2 yog qhov kev xaiv zoo dua. Tshwj xeeb tshaj yog rau cov neeg siv cov laptops tshiab, ib qhoUSB C 3.1 rau USB A cablelossis adapter uas txhawb nqa Gen 2 tuaj yeem txuas cov khoom siv rau cov khoom siv ib txwm muaj lossis cov hubs nrog ntau tus lej ntawm Type-A interfaces, thaum ua kom muaj kev xa cov ntaub ntawv ceev ceev.
Phau Ntawv Qhia Txog Kev Txheeb Xyuas thiab Kev Yuav Khoom
Vim muaj kev tsis meej pem hauv kev sau npe ua lag luam, thov nco ntsoov cov hauv qab no thaum yuav khoom:
Qee cov chaw tsim khoom yuav muab daim ntawv lo rauUSB 3.1 Gen 1ua "USB 3.0" los yog "SuperSpeed USB"
USB 3.1 Gen 2tej zaum yuav hu ua "SuperSpeed"USB 10 Gbps"
Cov qauv USB tshiab kawg tau raug hloov npe ua:USB 3.1 Gen 1tam sim no raug cais ua "USB 3.2 Gen 1", thiabUSB 3.1 Gen 2yog tam sim no "USB 3.2 Gen 2"
Thaum yuav khoomUSB C 3.1 rau USB Aor USB 3.1 A rau Micro B cables, xyuas kom meej tias cov lus piav qhia txog cov khoom qhia meej meej seb nws txhawb nqa Gen 1 (5 Gbps) lossis Gen 2 (10 Gbps) kom tsis txhob muaj kev cuam tshuam kev ua haujlwm vim yog lub cable.
Yuav kom koj tau txais kev ua tau zoo raws li koj xav tau, ua tib zoo xyuas cov lus qhia ntawm cov khoom es tsis txhob tsuas yog siv cov duab ntawm lub interface xwb. Yog tias tsim nyog, saib cov ntaub ntawv pov thawj.
Kev Txheeb Xyuas
Qhov kev xaiv ntawmUSB 3.1 Gen 1thiab Gen 2 feem ntau cuam tshuam nrog kev nrhiav qhov sib npaug ntawm qhov ceev, tus nqi, thiab qhov xav tau tiag tiag. Txawm nws yog qhov tshiabUSB C 3.1 rau USB Akev daws teeb meem hloov pauv lossis cov classicUSB 3.1 A mus rau MICRO BTxoj kev sib txuas, Gen 1 muab kev daws teeb meem txhim khu kev qha thiab pheej yig rau cov ntawv thov txhua hnub, thaum Gen 2 qhib txoj hauv kev ceev rau cov neeg siv kev tshaj lij thiab cov xwm txheej ua tau zoo. Raws li qhov kev thov rau qhov ceev ntawm kev xa cov ntaub ntawv los ntawm cov khoom siv txuas ntxiv mus, kev nkag siab txog qhov sib txawv no yuav pab koj txiav txim siab txog thev naus laus zis ntse dua hauv koj lub neej digital.
Yav tom ntej, nrog rau kev siv dav dav ntawm tus qauv USB4, qhov ceev ntawm kev xa cov ntaub ntawv yuav nce ntxiv mus txog 40 Gbps thiab koom ua ke Thunderbolt 3 protocol. Tab sis txog thaum ntawd,USB 3.1 Gen 1thiab Gen 2 yuav nyob ua ke rau lub sijhawm ntev, ua haujlwm rau ntau qhov xwm txheej ntawm daim ntawv thov thiab cov pab pawg neeg siv sib txawv.
