USByog "Universal Serial Bus", Suav lub npe hu ua Universal Serial Bus.Qhov no yog ib qho tshiab interface technology dav siv nyob rau hauv PC teb nyob rau hauv xyoo tas los no.USB chaw nres nkoj muaj cov yam ntxwv ntawm kev sib kis ceev ceev, txhawb kev sib pauv kub thiab txuas ntau yam khoom siv.Nws tau siv dav hauv txhua yam khoom siv sab nraud.Muaj peb hom USB chaw nres nkoj: USB1.1, USB2.0, thiab tsis ntev los no USB 3.0.Raws li txoj cai, USB1.1 tuaj yeem xa cov nrawm mus txog 12Mbps / SEC, thaum USB2.0 tuaj yeem xa nrawm txog 480Mbps / SEC, thiab rov qab tau tshaj USB1.1.
Raws li khoos phis tawj kho vajtse txhim kho ntawm qhov nrawm nrawm, cov khoom siv peripheral nce ib hnub dhau ib hnub, keyboard, nas, modem, tshuab luam ntawv, scanner twb paub rau txhua tus, lub koob yees duab digital, MP3 walkman los ntawm ib qho tom qab, ntau yam khoom siv, nkag mus rau hauv lub computer li cas?USB tau tsim rau lub hom phiaj no.
USB connector txoj kev loj hlob thiab evolution nyob rau hauv 20 xyoo dhau los
Txhua lub khoos phis tawj tuaj yeem ua rau qeeb qeeb los ntawm nws qhov txwv tsis pub txais thiab xa cov ntaub ntawv mus rau lub ntiaj teb sab nraud.Cov ntaub ntawv bottlenecks ntawm input/outputs (I/O) panels txwv cov ntaub ntawv xa mus thiab ua kom cov khoom siv tsawg dua.Tau ntau xyoo, 15 - thiab 25-pin D-Sub connectors tau hloov pauv hauv lawv lub peev xwm los muab cov khoom siv nrog cov ntaub ntawv xa tawm txaus I / O.Originating hauv kev siv tub rog, cov Mil-Spec connectors muaj kev txhim khu kev qha tus pin thiab lub qhov (socket) txuas, nrog rau cov vaj tsev rugged.Hloov kho cov Mil-Spec connectors rau kev lag luam versions thiab pricing lawv mus rau cov neeg siv khoom theem ua rau lawv de facto cov neeg siv khoom tus qauv, uas yog tam sim no dav siv nyob rau hauv video, computer accessories thiab ntau dua.Raws li qhov kev thov rau cov ntaub ntawv tus nqi nce los ntawm kilobytes mus rau megabytes, qhov chaw tsawg dua yog muaj rau kev sib txuas sab nraud, xav tau cov khoom sib txuas tshiab.Xyoo 1996, usB-IF, lub koom haum ntawm cov thawj coj hauv kev lag luam hluav taws xob, tau yug los thiab tso tawm thawj tiam ntawm USB chaw nres nkoj.Thawj qhov kev tso tawm yog kev txhim kho USB1.1 cov lus qhia tshwj xeeb los hloov cov array interface, uas cuam tshuam rau kev sib raug zoo ntawm cov khoom siv txuas ntxiv, suav nrog flash thiab sab nraud hard drives, scanners thiab printers.Kev sib txuas yog tsim los ntawm ib qho txuas me me nrog qhov pib hloov pauv ntawm 1.5Mb / s, siv qhov kev sib txuas qis qis nrog lub neej ntawm ntau txhiab zaus, tab sis tsuas yog nyob rau hauv ib qho kev taw qhia.
Ib qho txiaj ntsig tseem ceeb ntawm USB tus qauv yog lub peev xwm xa hluav taws xob thiab cov teeb liab ib txhij, ua rau cov chaw taws teeb ua haujlwm tsis muaj hluav taws xob sab nraud.Lub peev xwm "kub ntsaws" yog lwm qhov tseem ceeb ntawm USB ports.
Tsis muaj cov ntsiab lus nrog cov qauv uas twb muaj lawm, USB-IF tau tso tawm USB 4 qhov tshwj xeeb thaum lub Cuaj Hli 2019. Lub connector yuav tuav lub hom-C interface, tab sis yuav integrate Intel Thunder 3 nrog 40GB / s hloov tus nqi thev naus laus zis.USB 4 rov qab siv tau nrog LUB USB hom-C raws tu qauv, suav nrog USB 3.2, DisplayPort, thiab Thunder 3, ua kom yooj yim txuas rau tag nrho cov tiam tshiab ntawm cov khoom siv.Cov khoom siv nrog qhov kev sib txuas tshiab no yuav tsum tau ua los ntawm 2021.
Usb-yog qhia tau hais tias nws txoj kev cog lus rau kev hloov kho tas mus li, ua rau USB txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv tom ntej.
Qhov ntawd yog 20-xyoo keeb kwm ntawm USB connectors.Nrog kev txhim kho txuas ntxiv ntawm kev siv tshuab thoob ntiaj teb, kev hloov khoom siv hluav taws xob.Yav tom ntej USB connectors tseem yuav hloov kho kom tau raws li cov kev xav tau siab dua.
