USBndi kuyimitsidwa ndi kuphweka kwa socket yolumikizira zida zamagetsi zamakompyuta, ndipo mawonekedwe ake ndi mitundu yake amapangidwa ndi Intel, NEC, Compaq, DEC, IBM (), Microsoft (Microsoft) ndi Norterntelecom.
Ubwino winanso wofunikira wa USB ndikuti ndiyoyenera kusinthana kotentha, ndiye kuti, ikamagwira ntchito, imatha kulumikiza kapena kulumikiza zida za USB kuti mumalize kulumikizana kwenikweni kwa 1394.
Pakadali pano, ngakhale zida za USB zakhala zikugwiritsidwa ntchito kwambiri, zitsulo za USB2.0 ndizofala kwambiri, ndipo kuchuluka kwake ndi 480mbps pamphindikati.Ndi pafupifupi nthawi 40 kuposa momwe USB1.1 imafotokozera.Phindu lalikulu kwa makasitomala pakuwonjezera liwiro ndikuti makasitomala amatha kugwiritsa ntchito zida zotumphukira zowoneka bwino, ndipo zida zotumphukira zama liwiro osiyanasiyana zimatha kulumikizidwa ndi njira ya USB2.0 popanda kudandaula za vuto la kufalikira kwa data.
Universal Serial Bus (Chingerezi: Universal Serial Bus, yotchedwa Universal Serial Bus, yomwe imatchedwa: USB) ndi ndondomeko ya basi yomwe imagwirizanitsa mapulogalamu apakompyuta ndi zipangizo zam'mbali, komanso ndi luso lamakono la madoko a I / O;kafukufuku ayenera kuwonjezeredwa, ndipo zogulitsa ziyenera kutsimikiziridwa ndi kafukufuku, koma palibe kukopera komwe kumafunikira.Malingana ndi mlingo wotumizira, umagawidwa mu USB: 2.0, USB: 3.0, USB: 3.1 ndi USB4;USB3.1 ndi USB4 (alias typec) amatha kutumiza deta, kufalitsa mawu, chithunzi ndi kulipiritsa batire.Mphamvu yayikulu kwambiri ndi 20V5A (100W), ndipo IC (E-MARK) ndiyofunika.
Malingana ndi udindo, zizindikiro zomwe zili pamwambazi zikhoza kugawidwa m'magulu asanu:
Gulu loyamba: Zizindikiro zokhudzana ndi mphamvu, kuphatikizapo.
A) VBUS, mphamvu ya basi ya chingwe cha USB (nthawi zambiri imagwirizana ndi VBUS m'lingaliro lanu lenileni).
b) VCONN (chizindikiro chimangowoneka pa pulagi) chimagwiritsidwa ntchito kugawira mphamvu ku pulagi (ikhoza kuganiziridwa kuti mapulagi ena amatha kukhala ndi magetsi).
C) GND, chipangizo choyambira.
Mtundu II: USB2.0 chingwe chojambulira foni yam'manja, D+/D-, peyala imodzi yokha kumapeto kwa pulagi, yogwirizana ndi mawonekedwe akale a USB2.0.Komabe, kuti agwiritse ntchito bwino kutsogolo ndi kumbuyo, akhoza kuikidwa mosasamala.Mapeto azitsulo amatanthauzira magulu a 2, kotero kuti mapeto azitsulo amatha kuchita ping yoyenera malinga ndi momwe zilili.Type 3: USB3.1 chingwe cholipirira foni yam'manja, TX+/ ndi RX+/, kuti musamutse deta mwachangu.Pali ma seti a 2 a pulagi ndi ma socket end, oyenera kuyika kulikonse kutsogolo ndi kumbuyo.
Gulu lachinayi: chizindikiro chomwe chimagwiritsidwa ntchito pa Kukonzekera, pulagi ili ndi CC imodzi yokha, ndipo socket ili ndi CC1 ndi CC2 ziwiri.
Gulu lachisanu: Zizindikiro zomwe zimafunikira pakuwonjezera, mawonekedwe enieni a ntchito amasankhidwa ndi zotsatira zofananira.
Pamitundu yosiyanasiyana ya sockets ndi mapulagi omwe akufotokozedwa mu 3.1, ndizotheka kuti ma pini 24 ndi ma siginecha awa sagwiritsidwa ntchito pazofunsira zonse.Chonde onani muyezo wa USB Type-C.Komanso, mungazindikire kuti USBType-C 24 pini zizindikiro, Mphamvu (GND/VBUS) ndi deta zambiri (D+/D-/TX/RX) n'zogwirizana kwathunthu (kwa Mphamvu, mulimonse Ikani, zonse ndi zofanana. Zina, kuphatikizapo CC, SBU ndi VCONN, zimagwiritsidwa ntchito poyang'anira kubereka, mtundu wa mzere, ndi zina zotero.
