USBiri "Universal Serial Bus", Zita reChinese rinonzi Universal Serial Bus.Iyi ndiyo itsva interface tekinoroji inoshandiswa zvakanyanya muPC munda mumakore achangopfuura.USB port ine hunhu hwekukurumidza kutapurirana kumhanya, tsigira inopisa chinja uye batanidza akawanda maturusi.Yakave yakashandiswa zvakanyanya mumhando dzese dzekunze zvishandiso.Kune marudzi matatu e USB ports: USB1.1, USB2.0, uye munguva pfupi yapfuura USB 3.0.Tichifunga kuti, USB1.1 inogona kuunza kumhanya kusvika 12Mbps/ SEC, ukuwo USB2.0 ichikwanisa kuunza kumhanya kusvika ku480Mbps/ SEC, uye iri kumashure inoenderana ne USB1.1.
Sezvo hardware yekombiyuta inokura nokukurumidza, midziyo yeperipheral inowedzera zuva nezuva, keyboard, mouse, modem, printer, scanner inotozivikanwa kune vose, digital kamera, MP3 walkman inouya imwe pashure peimwe, midziyo yakawanda, sei kuwana kombiyuta yega?USB yakagadzirirwa chinangwa ichi.
USB yekubatanidza kuvandudza uye shanduko mumakore makumi maviri apfuura
Chero mudziyo wekombuta unogona kudzikiswa zvakanyanya nekugona kwayo kugashira uye kutumira data kune kunze kwenyika.Mabhodhoro edata pane yekuisa / kubuda (I/O) mapaneru anodzikamisa kuendesa ruzivo uye anoita kuti zvishandiso zvisashande.Kwemakore, 15 - uye 25-pini D-Sub zvibatanidza zvakachinja mukukwanisa kwavo kupa maperipherals ane akakwana I/O ekufambisa data rates.Kubva mumashandisirwo echiuto, aya Mil-Spec anobatanidza anoratidza yakavimbika pini uye socket yekubatanidza, pamwe nedzimba dzakasimba.Kugadzirisa aya Mil-Spec majoini kushanduro dzekutengesa uye kudzika mitengo kune iyo yevatengi nhanho inovaita iyo de facto yevatengi chigadzirwa standard, iyo yava kushandiswa zvakanyanya muvhidhiyo, komputa accessories uye nezvimwe.Sezvo kudiwa kwemazinga e data kunowedzera kubva ku kilobytes kusvika ku megabytes, nzvimbo shoma inowanikwa yekubatana kwekunze, inoda mitsva yekubatanidza.Muna 1996, usB-IF, mubatanidzwa wevatungamiriri veindasitiri yemagetsi, akazvarwa uye akaburitsa chizvarwa chekutanga che USB ports.Kuburitswa kwekutanga kwaive kwakagadziridzwa USB1.1 kutsanangurwa kwakagadzirirwa kutsiva iyo array interface, iyo yakanganisa kugarisana pakati pemaperipheral akawedzerwa, anosanganisira flash uye ekunze hard drive, scanner nemaprinta.Kubatana kunoitwa kuburikidza nediki diki rectangular yekubatanidza ine yekutanga kutamisa mwero we 1.5Mb/s, uchishandisa yakaderera yekuisa simba kubatana nehupenyu hunosvika zviuru zvenguva, asi munzira imwe chete.
Mukana wakakura weiyo USB chiyero kugona kufambisa simba uye masaini panguva imwe chete, zvichiita kuti zvishandiso zviri kure zvishande pasina simba rekunze.Iyo "hot plug" kugona ndechimwe chinhu chakakosha che USB ports.
Kwete kugutsikana nezviyero zviripo, USB-IF yakabudisa iyo USB 4 tsanangudzo munaSeptember 2019. Iyo yekubatanidza ichachengetedza Type-C interface, asi ichabatanidza Intel Thunder 3 ne 40GB / s transfer rate teknolojia.USB 4 iri kumashure inoenderana neiyo USB Type-C protocol, inosanganisira USB 3.2, DisplayPort, uye Kutinhira 3, kurerutsa kubatana kwechizvarwa chitsva chemidziyo.Midziyo ine iyi nyowani interface inotarisirwa ne2021.
Usb-kana inoratidza kuzvipira kwayo kuenderera mberi nekusimudzira, zvichiita kuti USB irambe ichiita basa rakakosha mukugadzirwa kwechizvarwa chinotevera chemidziyo.
Ndiyo nhoroondo yemakore makumi maviri ye USB connectors.Nekuenderera mberi kwekuvandudza tekinoroji yepasi rose, kutsiva kwezvigadzirwa zvemagetsi.Remangwana USB majoini anozogadziridzwa zvakare kuti asangane nepamusoro zvinodiwa.
