Nkag siab qhov sib txawv ntawm USB 3.0 thiab USB 2.0 cov xaim yog qhov tseem ceeb rau kev ua tiav cov ntaub ntawv hloov nrawm nrawm thiab kev them nqi zoo tshaj plaws. Thaum lawv yuav saib zoo sib xws, kev nce qib thev naus laus zis teeb lawv sib nrug. Cov lus qhia no rhuav tshem qhov sib txawv tseem ceeb hauv kev nrawm, kev tsim qauv, thiab lub hwj chim los pab koj kom txiav txim siab paub.
Tsib qhov sib txawv ntawm USB 3.0 thiab USB 2.0 cables
1. Lub cev tsim & rov qab zoo sib xws
Qhov txawv tshaj plaws yog sab hauv lub txuas. Tus qauv siv USB 2.0 cable muaj 4 pins (2 rau cov ntaub ntawv, 2 rau lub zog). USB 3.0 cable tsim ntawm qhov no los ntawm kev ntxiv 5 ntxiv pins, nqa tag nrho rau 9. Cov pins no yog nyob sib sib zog nqus hauv qhov txuas, tom qab daim tseem.
Lub Visual Clue: Ib txoj hauv kev nrawm kom paub qhov txawv lawv yog los ntawm xim. USB 3.0 cov chaw nres nkoj thiab cov ntsaws cia yog xiav sab hauv, thaum USB 2.0 feem ntau yog xim dub lossis dawb.
Kev sib xyaw: USB 3.0 yog rov qab nrov dua. Koj tuaj yeem ntsaws USB 3.0 chaw nres nkoj mus rau hauv USB 2.0 chaw nres nkoj (thiab lwm qhov {{}}}}}}}}}}}}} kev sib txuas yuav txwv rau USB 2.0 nrawm.
2. Cov Ntaub Ntawv Hloov Hloov Ceev
Qhov no yog qhov tseem ceeb tshaj plaws.
- USB 2.0: Qhov ntau tshaj plaws theoretical ceev yog 480 Mbps (siab- ceev).
- USB 3.0: Qhov ntau tshaj plaws theoretical ceev yog 5 gbps (superspeed). Qhov no yog tshaj kaum zaus sai dua USB 2.0.
Nyob rau hauv cov ntsiab lus, hloov tsheb 25 tus yeeb yaj kiab yuav siv li 70 vib nas this nrog USB 3.0, tab sis dhau 14 feeb nrog USB 2.0.
3. Cov Ntaub Ntawv Sib Kis
USB 2.0 tsuas yog ua cov ntaub ntawv hauv ib qho kev taw qhia nyob rau ib lub sijhawm -}} puas yog xa lossis tau txais. USB 3.0 qhia tau muaj pub dawb- ruplex cov ntaub ntawv hloov chaw. Ua tsaug rau nws cov ntaub ntawv ntxiv cov ntaub ntawv, nws tuaj yeem xa thiab tau txais cov ntaub ntawv ib txhij, ua cov haujlwm xws li tiag {6} Lub sijhawm cov ntaub ntawv backup ntau dua.
4. Lub zog xa khoom
- USB 3.0 muab ntau lub zog rau them koj cov khoom siv.
- USB 2.0: tuaj yeem xa mus txog 500 MA (0.5A).
- USB 3.0: tuaj yeem xa mus txog 900 MA (0.9a).
Qhov no txhais tau USB 3.0 tuaj yeem them cov khoom siv tau sai dua thiab lub zog ntau dua xav tau sab nraud kho vajtse.
5. Kev tswj hwm hwj chim & muaj txiaj ntsig
USB 2.0 Rho tawm tsis tu ncua sib txuas nrog cov khoom siv los xyuas cov ntaub ntawv, uas siv lub zog txawm tias thaum kaw. USB 3.0 siv ib qho kev cuam tshuam - Cov txheej txheem tsav tsheb, tso cai rau tus tswv tsev tsawg thaum cov ntaub ntawv npaj tau. Qhov no ua rau nws muaj zog dua -} heev.
Nkag siab cov xov hlau sab hauv USB cable
Paub txog txoj hlua hluav taws xob pab nrog kev txheeb xyuas thiab teeb meem. Tus qauv USB 2.0 cable muaj plaub xaim:
- Liab: VCC (Fais fab +5 v)
- Dub: gnd (av)
- Dawb: Cov ntaub ntawv -
- Ntsuab: Cov Ntaub Ntawv +
- Pinout (ntsib USB - ib qho txuas, hu rau sab laug), tus lej} (Data}), PIN 4 (GND / Dub). Ob lub pins sab nraud (1 & 4) tau ua rau muaj zog ua ntej.
Yuav ua li cas xaiv qhov siab -} Zoo USB cable
Ib qho tsis zoo -} Zoo cable tuaj yeem ntim koj qhov nrawm thiab muaj kev phom sij nyab xeeb thiab muaj kev phom sij. Ntawm no yog dab tsi saib rau:
1) Txheeb xyuas daim thaiv thaiv: Zoo Cables muaj cov ntawv ci txhuas ua kom pom kev ntxhib thiab cov ntaub thaiv npog cov ntaub ntawv hluav taws xob, txhim kho cov ntaub ntawv ruaj khov hloov.
2) Tshawb xyuas lub txuas: Saib rau ib tug muaj zog, ib -} daim pwm connector. Zam kev xoob xoob lossis tsis zoo. Cov neeg sib tw sab hauv yuav tsum yog huv thiab ci.
3) Mloog cov ntsuas cua: ib qho tuab tuab uas feem ntau qhia tau zoo dua, qis}} {} {- cov ntaub ntawv ceev.
4) Txheeb xyuas lub tsho: nyiam tpe -} coated cables tshaj pvc. TPE hloov kho tau yooj yim, ruaj, thiab ib puag ncig phooj ywg. Nws hnov qab smoother thiab yog tsis tshua muaj kev mus rau Tangling thiab tawg.
Kev Siv Tseem Ceeb thiab Kev Kho Txij Nkawm
1) Zam kev ntse: Tsis txhob poob siab lossis nruj coil cables, raws li qhov no tuaj yeem tsoo cov xov hlau sab hauv.
2) Rub los ntawm lub ntsaws: ib txwm nyem cov yas txuas lub taub hau thaum tsis hloov pauv, tsis yog cable nws tus kheej.
3) Khaws cov portions huv si: tiv thaiv cov txuas ntawm ya raws thiab hmoov av, uas tuaj yeem ua rau oxidation thiab kev sib txuas tsis zoo.
4) Cia kom deb ntawm tshav kub: Tsis txhob khiav cables ze zog cua sov, uas muaj qhov kub kub tuaj yeem txwv lub hnab yas yas thiab lub rwb thaiv tsev sab nraud.
Xaus: Qhov twg koj yuav tsum xaiv?
Rau kev sib txuas niaj hnub sab nraud sib zog, SSDs, lossis lwm yam siab {}}} Perform ipherals, USB 3.0 yog tus yeej ntshiab thiab kev ua tau zoo thiab lub zog zoo. However, for basic devices like keyboards, mice, or low-speed accessories, a USB 2.0 cable is perfectly adequate and often more cost-effective. Nco ntsoov phim koj cable rau koj lub peev xwm lub peev xwm los qhib nws lub peev xwm.[Tiv tauj peb]
