USB amatanthauza "Universal Serial Bus", dzina lachi China ndi Universal Serial Bus.Uwu ndiukadaulo watsopano wamawonekedwe womwe wagwiritsidwa ntchito kwambiri pa PC zaka zaposachedwa.Mawonekedwe a USB ali ndi mawonekedwe a liwiro lotumizira mwachangu, kuthandizira plugging yotentha, ndi kulumikizana kwa zida zingapo.Zakhala zikugwiritsidwa ntchito mu zipangizo zosiyanasiyana zakunja.Pali mitundu itatu yolumikizira USB: USB1.1 ndi USB2.0, ndi USB3.0 yomwe yawoneka m'zaka zaposachedwa.Mwachidziwitso, kuthamanga kwa USB1.1 kumatha kufika ku 12Mbps / s, pamene USB2.0 ikhoza kufika 480Mbps / s, ndi kugwirizana kumbuyo kungakhale USB1.1.Ndi chitukuko chofulumira cha hardware yamakompyuta, zotumphukira zochulukira, kiyibodi, mbewa, ma modemu, osindikiza, makina ojambulira akhala akudziwika kale, makamera a digito, osewera a MP3 nawonso adatsata.Kodi timapeza bwanji ma PC kudzera pazida zambiri?USB idabadwira izi.Msika uli ndi kufunikira kwakukulu kwaZolumikizira za USB, makamaka zolumikizira zolumikizira madzi za USB.Izi ndichifukwa choti njira zachikhalidwe za USB sizingakwaniritsenso zosowa zamakasitomala.Masiku ano, kachulukidwe ka zinthu zomwe ogula amagula akuchulukirachulukira, zofunikira zotumizira zimakwera, komanso kufunikira kwamagetsi kumatchulidwanso, ndipo kumafunika kugwiritsidwa ntchito m'malo ambiri.Zofunikira pakupanga zolumikizira zopanda madzi za USB zitha kufotokozedwa mwachidule monga: kukhulupirika kwa chizindikiro, kugwiritsa ntchito mphamvu, kuteteza chilengedwe: 1. Zofunikira za kukhulupirika kwa ma Signal Kukweza kukhulupirika kwa chizindikiro, kufulumira kwa data.2. Zofunikira pakugwiritsa ntchito mphamvu 3. Zofunikira pachitetezo cha chilengedwe Kuti apereke chitetezo cha chilengedwe chomwe ogwiritsa ntchito amafuna, zolumikizira za USB zopanda madzi ziyenera kukhala ndi zisindikizo za rabara ndi chigoba chopanda msoko kuti zisalowe madzi, zolumikizira izi ziyenera kukhala IPX8 yosalowa madzi (malinga ndi IEC 60529), ndipo iyenera kukhala yolimba mokwanira kuti ikhale yolumikizana ndi kumasulidwa kambirimbiri .
