Ephambi kwezinduna inqwaba amadivaysi ezinjalo kuyinkinga: ndawo ukuze ujike kwenye idivayisi. Nokho, uma omunye uxhumano kungaba ngaphandle kokubukela phansi umsebenzi zikhutshaziwe. Futhi uma lokhu kungeke kwenzeke? Kuyadingeka ukuba landise inani lawo nezimbobo. Lokhu kungenziwa, uma uthenga i-USB ihabhu. Kuyinto idivayisi elincane ngokuvamile eyodwa input bese multiple-USB okukhiphayo. Isibalo nezimbobo ezifana lokhu ukwenze ngento eyodwa kungaba kusuka 2 kuya ku-90, kodwa onobuhle ezivamile kokuba abafika kwabangu-10 imibono. Design, umbala kanye nomklamo ezihlukahlukene.

USB-concentrators kungaba ngezinhlobo eziningi:

• USB PCI-ikhadi, okuyinto ixhunywe omunye nezixhumi umbadlana. Ukuze uxhume isidingo ukuvula iyunithi uhlelo bese ufaka lolu hlobo Ihabhu endaweni slot ekhethekile. Ukusebenza kudinga, nakuba ingenkulu kakhulu, kodwa amakhono athile kanye nolwazi. Uma ungenalo labo, uthola uhlobo oluhlukile kudivayisi. Ngaphezu nezinkinga ukufakwa, USB PCI ikhadi akulula kakhulu ukusebenzisa: zonke okokufaka kukhona ngemuva chassis, elinikeza nobunzima ezithile.
• Passive-USB ihabhu. Ngokuvamile, lezi onobuhle babe kusuka 2 kuya ku-6 okokufaka. Ukusebenzisa kwabo ngempela kungagcini: angithi anganikeza ukusebenza ngesikhathi esisodwa Amadivayisi amandla abalambele amaningi. Izizinda zalolu hlobo zivamise sisetshenziswe ku-laptops.
• Active-USB Hub ngesikhathi esifanayo exhunywe kwi-amapayipi kanye PC. Linganikeza uxhumano kanyekanye kanye nokusebenza inani elikhulu kumadivayisi (ezinye tinkhulumo babe 90 okokufaka).

Kubalulekile kakhulu ukuthi wena ukuxhuma-USB ihabhu kuyinto ukufakelwa isofthiwe kanye nabashayeli, ukuhlinzeka nezimbobo eyengeziwe emsebenzini. Ngemva kokufaka kuqedile, uhlelo ubonisa umyalezo obonisa ezilungele ukusebenza.

kuphakama Ngezinye izikhathi lapho yokuxhuma amaningi nobunzima-USB Kudivayisi ngenxa nezimbobo kakhulu eduze zishiyane.

Uthenge ihabhu USB, xhuma, kodwa kukhona inkinga: kuphi akubeka. Kukhona amamodeli ukuthi umane ume etafuleni noma uhlelo unit, kukhona amadivayisi ahlinzeke ukugibela udonga noma iyiphi indawo ngokumile noma ngokuvundlile.

Ngokuvamile, eningi onobuhle. Ziyahlukahluka kuye kunombolo kwamachweba, uhlobo indawo, ukubukeka, Ubukhulu, indlela ukulungisa, ukufakwa kanye, yebo, izindleko. Kulesi ezihlukahlukene, ngokungangabazeki uyobe ugxekwa ukuthola into oyithandayo.
