Ngokuthuthuka okusheshayo kobuchwepheshe kanye nenani elihlala likhuphuka lamadivayisi esiwasebenzisayo ekuphileni kwethu kwansuku zonke, isidingo sezixazululo ezisebenza kahle neziguquguqukayo zokuxhuma sesibaluleke kakhulu kunangaphambili.Eyaziwa nangokuthi izixhumi ze-Universal Serial Bus,Izixhumi ze-USBsiguqule indlela esixhuma ngayo futhi sixhumana ngayo nazo zonke izinhlobo zamadivayisi.Kule bhulogi, sizohlola izinzuzo nezici zeIzixhumi ze-USB, ngokugxila ngokukhethekile ekufuneni okukhulayo kokungangeni kwamanziIsixhumi se-USBimikhiqizo.

I-USB imele i-Universal Bus futhi isibe ubuchwepheshe bokusebenzisana obudumile emkhakheni we-PC eminyakeni yamuva.Inikeza isivinini sokudlulisa esisheshayo, ukwesekwa kwe-hot-plug, kanye nekhono lokuxhuma amadivayisi amaningi ngesikhathi esisodwa,Izixhumi ze-USBabe yingxenye ebalulekile yezinhlobonhlobo ze-peripherals.Ukuze kuhlangatshezwane nesidingo esikhulayo sokudluliswa kwedatha, izinhlobo ezintathu eziyinhloko zokusebenzelana kwe-USB ziye zavela, okuyi-USB1.1, USB2.0 kanye ne-USB3.0.Isivinini sokudluliswa kwesithiyori se-USB1.1 singu-12Mbps, kuyilapho i-USB2.0 ingafinyelela isivinini esimangalisayo sokudlulisela esingu-48Mbps, futhi ibuyela emuva iyahambisana neyandulelayo i-USB1.1.

IIsixhumi se-USBimakethe ibe nokukhula okukhulu, ikakhulukazi emkhakheni wokuvikela amanziIsixhumi se-USBimikhiqizo.Izisombululo ze-USB zendabuko ngokuvamile ziyehluleka ukuhlangabezana nezidingo zemikhiqizo yabathengi.Imikhiqizo yanamuhla yabathengi ayiminyene nje kuphela, kunesidingo esikhulayo samazinga okudlulisela aphezulu, kodwa futhi nezidingo zokusetshenziswa kwamandla ezindaweni ezihlukahlukene.Ukuphendula lokhu, ukungena kwamanziIzixhumi ze-USBkwavela njengoba izikhathi zidinga futhi kwaba yisixazululo esibalulekile.

Izinzuzo zezixhumi ze-USB ezingenamanzi ziningi.Okokuqala, banikeza ukuvikeleka okuthuthukisiwe kumswakama nezinye izakhi zangaphandle, ukwelula impilo yesixhumi ngokwaso nokunciphisa ithuba lokulimala kwemishini ngenxa yokuchayeka kwamanzi.Lokhu kubenza balungele ukusetshenziswa ngaphandle noma ezindaweni ezinokhahlo lapho ukumelana kwamanzi kubalulekile.Okwesibili, isixhumi se-USB esingangeni manzi sinikeza ukudluliswa kwedatha okuthembekile nokuzinzile, ukunciphisa ingozi yokulahlekelwa idatha noma ukuphazamiseka kwesignali ngenxa yokungena kwamanzi.

Ukwengeza, lezi zixhumi ziklanyelwe ukumelana nezimo ezihlukahlukene ezinzima, okuhlanganisa amazinga okushisa adlulele kanye nokuchayeka othulini noma imfucumfucu.Izixhumi ze-USB ezingangeni manzi ziqinisekisa ukuqina nokusebenza okungaguquguquki kungakhathaliseki ukuthi uzisebenzisa ezinhlelweni zasolwandle, izindawo zezimboni, noma imisebenzi yangaphandle.Futhi, aklanyelwe ukuthi abe lula ukuwasebenzisa, afakeke kalula futhi ashintshe ukuze kube nokuxhumana okubushelelezi, okungenazinkinga.

Isidingo esikhulayo sezixhumi ze-USB ezingangeni manzi sibonisa isidingo sezixazululo eziguquguqukayo neziqinile zokuxhuma ezifanelana nempilo yethu yesimanje.Kusukela kuma-smartphones namathebulethi kuya kumakhamera edijithali nezidlali ze-MP3, sithembele kuzixhumi ze-USB ukuze sifinyelele kalula futhi sihlanganyele namadivayisi ethu.Ngokukhetha isixhumi se-USB esingangeni manzi, abathengi bangaphumula kalula bazi ukuthi idivayisi yabo ivikelwe kahle futhi izosebenza kahle ngisho nasezimeni zemvelo eziyinselele.

Sengiphetha, izixhumi ze-USB seziyingxenye ebalulekile yokuphila kwethu kwansuku zonke kwedijithali.Ngesivinini sazo sokudlulisa esisheshayo, usekelo lwe-hot-plug, namandla okuxhuma amadivaysi amaningi, izixhumi ze-USB ziguqule indlela esisebenzisana ngayo nokuxhumana namadivayisi ethu.Isidingo esikhulayo sezixhumi ze-USB ezingangeni manzi sigqamisa isidingo sezixazululo eziqinile neziqinile zokuxhuma ezingahlangabezana nezidingo zezindawo ezahlukahlukene.Kungakhathaliseki ukuthi ungumshisekeli wangaphandle noma usebenza endaweni yezimboni, izixhumi ze-USB ezingangeni manzi ziqinisekisa ukuxhuma okuthembekile, okuphumelelayo nokuhlala isikhathi eside.Yamukela intuthuko kubuchwepheshe be-USB futhi uqinisekise ukuxhumana okungenazihibe kuwo wonke amadivayisi akho.
