USBchiyero uye kurerutsa kwemagetsi komputa peripheral yekubatanidza socket, uye maratidziro ayo uye modhi zvinogadzirwa neIntel, NEC, Compaq, DEC, IBM (), Microsoft (Microsoft) uye Norterntelecom.
Imwe bhenefiti yakakosha ye USB ndeyekuti yakakodzera kuchinjisa inopisa, ndiko kuti, panguva yekushanda, inogona kubatanidza zvakachengeteka kana kubvisa USB midziyo kuti ipedze yechokwadi 1394 yekubatanidza.
Panguva ino, kunyangwe midziyo yeUSB yave kushandiswa zvakanyanya, USB2.0 zvigadziko zvakajairika, uye huwandu hwayo hwekutamisa i480mbps pasekondi.Inenge ka40 iyo ye USB1.1 yakatarwa.Kubatsira kukuru kune vatengi vekuwedzera kumhanya ndeyekuti vatengi vanogona kushandisa zvakanyanya mashandiro emidziyo yekutenderera, uye madhizaini ekumhanya kwakasiyana anogona kubatanidzwa kune USB2.0 nzira pasina kunetsekana nezve bhodhoro mhedzisiro yekufambiswa kwedata.
Universal Serial Bus (ChiRungu: Universal Serial Bus, inonzi: USB) ndeye serial bhazi yakatarwa inobatanidza komputa software uye peripheral zvishandiso, uye zvakare chiyero chehunyanzvi cheI/O ports;tsvagiridzo inofanirwa kuwedzerwa, uye zvigadzirwa zvinofanirwa kusimbiswa netsvagurudzo, asi hapana kodzero yekodzero inodiwa.Maererano nehuwandu hwekutumira, yakakamurwa kuva USB: 2.0, USB: 3.0, USB: 3.1 uye USB4;USB3.1 uye USB4 (alias typec) inogona kufambisa data, kutumira ruzha, mufananidzo uye bhatiri kuchaja.Iyo yakanyanya simba ndeye 20V5A (100W), uye IC (E-MARK) inodiwa.
Zvinoenderana nebasa, masaini ari pamusoro anogona kukamurwa muzvikamu zvishanu:
Chikamu chekutanga: Simba-ane hukama masaini, kusanganisira.
A) VBUS, iyo buspower ye USB tambo (kazhinji inopindirana neVBUS mupfungwa yako chaiyo).
b) VCONN (chiratidzo chinongoonekwa chete papuragi) inoshandiswa kugovera simba kune plug (inogona kufungidzirwa kuti mamwe mapulagi anogona kunge aine simba redunhu).
C) GND, chigadziro chekugadzika.
Type II: USB2.0 mbozha mbozha yekuchaja tambo, D+/D-, peya imwe chete pamagumo eplug, inoenderana neyakare USB2.0 yakatarwa.Zvisinei, kuitira kuti ishandiswe zviri nani kumberi uye kumashure, inogona kuiswa pasina.Iyo socket yekupedzisira inotsanangura 2 mapoka, kuitira kuti socket yekupedzisira iite yakakodzera ping zvinoenderana nemamiriro chaiwo.Type 3: USB3.1 nhare yekuchaja tambo, TX+/ uye RX+/, yekumhanyisa data kutamisa.Kune 2 seti yeplug uye socket inogumira, yakakodzera chero kuiswa kumberi uye kumashure.
Chikamu chechina: chiratidzo chinoshandiswa kuKugadzirisa, plug ine chete CC, uye socket ine maviri CC1 uye CC2.
Chikamu chechishanu: Masaini anodiwa kune yekuwedzera mhedzisiro, iyo chaiyo application mamiriro inosarudzwa neinowirirana yekuwedzera maitiro.
Kune marudzi akasiyana ezvigadziko nemapulagi anotsanangurwa mu3.1, zvinokwanisika kuti aya mapini makumi maviri nemana nemasaini haazoshandiswe kune ese maapplication.Ndokumbira utarise kune chiyero che USB Type-C.Mukuwedzera, unogona kuona kuti mu USBType-C 24 pini zviratidzo, Simba (GND/VBUS) uye data data (D+/D-/TX/RX) inoenderana zvachose (yeSimba, zvakadaro Isa, zvese zvakafanana. Mamwe, anosanganisira CC, SBU uye VCONN, anoshandiswa pakuongorora kubereka, mhando yemutsetse, nezvimwe.
