Ib qho chaw nres nkoj USB yog tus qauv kev sib txuas rau kev sib txuas rau cov computers thiab cov khoom siv hluav taws xob. USB stands rau Universal Serial Bus , ib qho kev lag luam txuj rau luv luv-cov ntaub ntawv sib txuas lus. USB chaw nres nkoj cia USB khoom txuas nrog rau lwm tus thiab hloov cov ntaub ntawv dua USB cables. Lawv kuj tuaj yeem muab hluav taws xob fais fab thoob plaws cov kab txuas mus rau qhov uas xav tau nws.
Ob wired thiab wireless versions ntawm USB qauv nyob ua ib ke, tab sis tsuas yog wired version nrog USB ports thiab cables.
Koj Yuav Ua Li Cas Rau Ib Lub Chaw Nkag Tawm?

- USB printers yuav tsum sib koom hauv lub tsev network
Rau cov ntaub ntawv xa mus rau lub computer-hauv-computer tsis muaj network, USB drives tseem qee zaum siv los luam cov ntaub ntawv ntawm cov khoom siv.
Siv lub chaw nres nkoj USB
Txuas ob qho khoom siv ncaj qha nrog ib lub USB cable los ntawm kev ntsaws txhua qhov kawg mus rau hauv ib qho chaw nres nkoj USB. (Qee cov cuab yeej siv ntau tshaj ib qho chaw nres nkoj USB, tab sis tsis txhob ntsaws ob sab hauv ib kab rau hauv tib lub cuab yeej, vim qhov no ua rau hluav taws xob puas!)
Koj tuaj yeem txuas cab rau hauv USB chaw nres nkoj txhua lub sijhawm tsis hais seb puas muaj cov khoom siv txuam nrog lossis tawm. Ua raws li cov lus qhia uas tau muab nrog koj cov khoom ua ntej yuav tshem cov kab mob USB. Muaj qee zaum, unplugging ib tug USB cable los ntawm ib tug ciav kev ua haujlwm yuav ua rau
Ntau lub USB khoom kuj tuaj yeem txuas nrog sib siv lub USB hub . Ib lub khwb USB hub rau hauv ib qho chaw nres nkoj USB thiab muaj cov chaw nres nkoj ntxiv rau lwm cov khoom siv txuas mus txuas ntxiv. Yog tias siv lub hub hauv USB, ntsaws cov kab txuas rau txhua lub tshuab thiab txuas mus rau lub hub ib leeg zuj zus.
USB-A, USB-B thiab USB-C Hom Chaw
Ntau hom kev ua si ntawm lub cev muaj nyob rau hauv USB ports:
- USB-B (Hom B) : Qhov kev sib txuas ntawm no yog kwv yees 1.4 cm (9/16 hauv) qhov ntev ntawm 0.65 cm (1/4 hauv) qhov siab feem ntau pom muaj nyob rau ntawm cov routers, computers, printers thiab consoles consoles. USB sticks feem ntau feature USB-B connectors kuj.
- USB-A (Hom A) : Tsawg tshaj li hom B, USB A yog ze li ntawm cov xwm txheej thiab feem ntau siv rau cov nas ntiv taw thiab cov twj twv tu.
- Micro USB : Yog li Micro USB versions ntawm ob leeg USB-A thiab USB-B kuj muaj - me versions tshaj lawv cov counter counterts, nrov ntawm mobile pab kiag li lawm. (Cov laus tab sis tam sim no tsis ntev tom ntej "Mini USB" versions kuj muaj nyob rau qee cov laus siv.)
- USB hom C : Nrog rau qhov ntev ntawm 0.84 cm los ntawm 0.26 cm, tus txheej txheem tshiab no yog tsim los hloov A thiab B nrog cov kev sib tshuam me me kom zoo dua rau hauv daim ntawv thim hom feem ntawm mobile devices
Txhawm rau txuas ib lub tshuab ntaus ib hom khoom siv nrog lwm hom, tsuas yog siv hom xov tooj ntawm cov kab mob kom haum nrog txhua qhov kawg. USB cables yog manufactured los txhawb tag nrho cov kev txhawb kev sib txuas ntawm hom thiab txiv neej / poj niam xaiv.
Versions ntawm USB

USB chaw nres nkoj tsis ua hauj lwm?
Tsis yog txhua yam mus ua haujlwm zoo thaum koj ua haujlwm nrog cov computers. Muaj ntau yam vim li cas ib qho chaw nres nkoj ntawm USB tuaj yeem nres tsis ua hauj lwm. Nov yog ua li cas thaum koj ntsib teeb meem.
Cawm rau USB
USB ports yog ib qho kev hloov mus rau cov chaw nres tsheb thiab cov qub txig ntawm cov laus hauv cov laus. USB chaw nres nkoj txhawb zog sai dua (feem ntau 100 x lossis ntau dua) cov ntaub ntawv hloov tsheb tshaj li qub los yog thaum pib.
Rau computer networking , qee zaum siv cov Ethernet ports tsis siv USB. Rau qee hom computer peripherals, FIreWire ports kuj muaj qee zaus. Ob qhov Ethernet thiab FireWire tuaj yeem muab cov kev ua tau zoo dua USB, tab sis cov interfaces tsis muab cov hwj huam thoob cov hlau.
