USB 2.0 vs 3.2: Kev sib piv ceev thiab kev ua tau zoo
Cov Lus Qhia
- 1. Nkag siab txog USB Versions
- 2. Qhov txawv ntawm USB 2.0 thiab USB 3.2
- 3. Kev cuam tshuam rau cov neeg siv
- 4. Cov lus xaus
Universal Serial Bus (USB) cov qauv tau hloov pauv peb txuas nrog peb li cas. Qhov sib txawv ntawm USB 2.0 thiab USB 3.2 tam sim no tseem ceeb dua. Kab lus no saib ntawm qhov zoo thiab qhov tsis zoo ntawm txhua tus, thiab lawv cuam tshuam rau cov neeg siv li cas.
Ntsiab Cai
Nkag siab txog USB Versions
Txhawm rau nkag siab qhov sib txawv ntawm USB 2.0 thiab USB 3.2, peb yuav tsum saib seb USB thev naus laus zis tau loj hlob li cas. Los ntawm hom USB 2.0 mus rau USB 3.x tshiab, txhua qhov hloov tshiab tau hloov pauv loj. Cov kev hloov pauv no suav nrog kev hloov cov ntaub ntawv sai dua, muaj zog dua, thiab kev ua haujlwm zoo dua.
USB 2.0
USB 2.0 tau tawm hauv xyoo 2000 thiab tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev txav cov ntaub ntawv thiab txuas cov khoom siv. Nws tuaj yeem txav cov ntaub ntawv ntawm tus nqi ntawm 480 Mbps, dhia loj ntawm USB 1.1 qub. Niaj hnub no, USB 2.0 li tseem nrov rau tej yam xws li khaws cia cov ntaub ntawv thiab them xov tooj.
USB 3.0, 3.1, thiab 3.2
USB 3.0 tuaj txog hauv xyoo 2008 thiab yog ib kauj ruam loj. Nws tuaj yeem txav cov ntaub ntawv ntawm 5 Gbps, qhia "SuperSpeed" USB. Qhov no txhais tau tias hloov cov ntaub ntawv sai dua thiab siv zog zoo dua. Txij thaum ntawd los, USB 3.x tau ua kom zoo dua qub, nrog USB 3.1 thiab 3.2 muab kev nrawm dua thiab ntau dua.
USB 3.1 (tseem hu ua SuperSpeed +) tau tawm hauv xyoo 2013. Nws tau ua ob npaug ntawm cov ntaub ntawv tus nqi mus rau 10 Gbps, ua rau nws zoo dua rau cov haujlwm uas xav tau ntau cov ntaub ntawv.
USB 3.2, tso tawm xyoo 2017, coj kev xaiv sai dua. Nws suav nrog USB 3.2 Gen 1 (txog 5 Gbps), USB 3.2 Gen 2 (txog 10 Gbps), thiab USB 3.2 Gen 2x2 (txog 20 Gbps). Cov kev nrawm no ua tau raws li qhov xav tau ntawm cov khoom siv niaj hnub no thiab cov apps.
Qhov hloov tshiab hauv USB 3.x tau hloov pauv peb cov ntaub ntawv hloov pauv li cas. Lawv ua kom sib koom cov ntaub ntawv yooj yim, backups ceev, thiab saib cov yeeb yaj duab du. Paub txog qhov sib txawv USB versions pab cov neeg siv xaiv qhov zoo tshaj plaws rau lawv cov khoom siv thiab tau txais txiaj ntsig zoo tshaj plaws ntawm lawv.
Qhov txawv ntawm USB 2.0 thiab USB 3.2
Cov kev cuam tshuam rau cov neeg siv
Xaus
Kev hloov ntawm USB 2.0 mus rau USB 3.2 tau ua rau muaj kev hloov pauv loj. Cov kev hloov pauv no suav nrog kev hloov cov ntaub ntawv sai dua, muaj zog dua, thiab ua haujlwm zoo dua. Kev loj hlob ntawm kev siv USB yog tsav cov tswv yim tshiab thiab tsim lub neej yav tom ntej. Rau cov lag luam thiab kev lag luam uas yuav tsum tau txhim khu kev qha thiab scalable computer systems, rugged rackmount computers muab cov kav ntev thiab kev ua tau zoo uas xav tau los siv cov kev sib txuas siab tshaj plaws xws li USB 3.2.
USB 3.2 qhov nrawm txog li 20Gbps yog qhov zoo tshaj plaws rau kev ua haujlwm zoo li streaming 4K yeeb yaj kiab thiab txav cov ntaub ntawv loj. Nws kuj ua rau kev sib txuas cov cuab yeej yooj yim dua. Yog tias koj daim ntawv thov xav tau compact, high-performance systems, xav txog a fanless industrial embedded PC. Ntxiv rau, USB 3.2 muaj cov kev xaiv them nyiaj zoo dua, yog li koj tuaj yeem khaws koj cov khoom siv them txhua qhov chaw. Raws li tus thawj coj industrial computer chaw tsim tshuaj paus, SINSMART TECH ua kom nws cov tshuab tau nruab los tswj cov kev nce qib no zoo.
USB 4.0 thiab qhov nce ntawm USB-C txuas tau teeb tsa kom coj kev txhim kho ntau dua. Rau kev lag luam uas xav tau kev teeb tsa muaj zog, a 4U rackmount lub computer yog qhov kev xaiv zoo tshaj plaws rau kev txhawb nqa kev muaj peev xwm ceev USB. Ntxiv thiab, Advantech embedded PCs yog tsim los ua kom tau raws li cov kev xav tau ntawm cov ntawv thov kev lag luam siab heev uas tau txais txiaj ntsig los ntawm cov kev hloov kho txuas ntxiv.
Raws li USBs tau zoo dua, peb tuaj yeem tos ntsoov rau kev ua haujlwm sai dua, kev sib txuas ntxiv, thiab kev sib raug zoo rau xyoo tom ntej. Rau cov neeg tab tom nrhiav kev sib koom ua ke cov cuab yeej siv thev naus laus zis USB rau hauv lawv lub tshuab, koom tes nrog kev paub dhau los embedded PC manufacturers ua kom muaj kev vam meej mus ntev. Qhov no yuav pab tau peb mus nrog peb lub neej digital.
