I-USByi-"Universal Serial Bus", Igama lesiShayina libizwa nge-Universal Serial Bus.Lona ubuchwepheshe obusha bokusebenzisana obusetshenziswa kabanzi emkhakheni we-PC eminyakeni yamuva.Imbobo ye-USB inezici zejubane lokudlulisa ngokushesha, isekela ukushintshashintsha okushisayo futhi ixhume amadivaysi amaningi.Isetshenziswe kabanzi kuzo zonke izinhlobo zamadivayisi angaphandle.Kunezinhlobo ezintathu zezimbobo ze-USB: i-USB1.1, i-USB2.0, kanye ne-USB 3.0 yakamuva.Ngokombono, i-USB1.1 ingaletha isivinini esingafika ku-12Mbps/SEC, kuyilapho i-USB2.0 ingaletha isivinini esifika ku-480Mbps/SEC, futhi ibuyela emuva iyahambisana ne-USB1.1.
Njengoba i-hardware yekhompiyutha ikhula ngesivinini esigcwele, imishini ye-peripheral yanda usuku nosuku, ikhibhodi, igundane, imodemu, iphrinta, isithwebuli sesivele saziwa yibo bonke, ikhamera yedijithali, i-MP3 walkman iza ngokulandelana, imishini eminingi, indlela yokufinyelela ikhompyutha yomuntu siqu?I-USB idalelwe le njongo.
Ukuthuthukiswa kwesixhumi se-USB kanye nokuziphendukela kwemvelo eminyakeni engama-20 edlule
Noma iyiphi idivayisi yekhompuyutha ingasehliswa kakhulu ijubane layo elilinganiselwe lokwamukela nokudlulisa idatha emazweni angaphandle.Izithiyo zedatha kumaphaneli e-input/output (I/O) akhawulela ukudluliswa kolwazi futhi enza amadivaysi angasebenzi kahle.Ngokuhamba kweminyaka, izixhumi ze-D-Sub ezingu-15 – nezingu-25-pin ziye zashintsha ekhonweni lazo lokuhlinzeka ngamapheripheral ngamanani anele edatha yokudlulisela ye-I/O.Isuka ezinhlelweni zempi, lezi zixhumi ze-Mil-Spec zifaka iphinikhodi nokuxhumana okuthembekile, kanye nezindlu ezimangelengele.Ukushintsha lezi zixhumi ze-Mil-Spec zibe izinguqulo zezentengiso futhi uzifake intengo ezingeni lomthengi kuzenza izinga lomkhiqizo wabathengi we-de facto, manje osetshenziswa kabanzi kuvidiyo, izinsiza zekhompyutha nokunye okwengeziwe.Njengoba isidingo sezilinganiso zedatha sikhuphuka sisuka kumakhilobhayithi siye kumamegabhayithi, sincane isikhala esitholakalayo sokuxhuma kwangaphandle, okudinga izixhumanisi ezintsha zokusebenzelana.Ngo-1996, i-usB-IF, i-consortium yabaholi bemboni ye-electronics, yazalwa futhi yakhulula isizukulwane sokuqala samachweba we-USB.Ukukhishwa kokuqala kwakuwukucaciswa okuthuthukisiwe kwe-USB1.1 okuhloselwe ukumiselela isixhumi esibonakalayo samalungu afanayo, okuthinte kabi ukusebenzisana phakathi kwama-peripheral anwetshiwe, okuhlanganisa iflash kanye nama-hard drive angaphandle, izikena namaphrinta.Uxhumano lwenziwa ngesixhumi esincanyana esingunxande esinesilinganiso sokudlulisa sokuqala esingu-1.5Mb/s, kusetshenziswa amandla okufaka aphansi ahambisana nempilo ecishe ibe izinkulungwane zezikhathi, kodwa ohlangothini olulodwa kuphela.
Inzuzo enkulu yezinga le-USB yikhono lokudlulisa amandla namasignali ngesikhathi esisodwa, okuvumela amadivayisi akude ukuthi asebenze ngaphandle kwamandla angaphandle.Amandla we-“hot plug” angesinye isici esibalulekile sezimbobo ze-USB.
Inganelisekile ngamazinga akhona, i-USB-IF ikhiphe ukucaciswa kwe-USB 4 ngoSepthemba 2019. Isixhumi sizogcina isixhumi esibonakalayo sohlobo C, kodwa sizohlanganisa i-Intel Thunder 3 nobuchwepheshe bezinga lokudlulisa elingu-40GB/s.I-USB 4 ibuyela emuva iyahambisana nephrothokholi yohlobo C lwe-USB, okuhlanganisa i-USB 3.2, i-DisplayPort, ne-Thunder 3, okwenza ukuxhumana kube lula kusizukulwane esisha samadivayisi.Amadivayisi analesi sikhombimsebenzisi esisha kulindeleke ngo-2021.
I-Usb-uma ibonisa ukuzibophezela kwayo ekuthuthukisweni okuqhubekayo, okwenza i-USB iqhubeke idlala indima ebalulekile ekwakhiweni kwesizukulwane esilandelayo samadivayisi.
Lowo umlando weminyaka engu-20 wezixhumi ze-USB.Ngokuthuthuka okuqhubekayo kobuchwepheshe bomhlaba wonke, ukushintshwa kwemikhiqizo ye-elekthronikhi.Izixhumi ze-USB zesikhathi esizayo nazo zizobuyekezwa ukuze zihlangabezane nezimfuneko eziphezulu.
