I- port ye-USB iyinhlangano ejwayelekile yexhumano lwekhebula lamakhompyutha abo kanye namadivaysi kagesi abathengi. Izitatimende ze-USB ze-Universal Serial Bus , inqubo yemboni yokuxhumana kwedatha yedijithali emfushane. Amapayipi e-USB avumela amadivayisi we-USB ukuba axhumeke komunye nomunye futhi adlulisele idatha yedatha ngaphezu kwezingcingo ze-USB. Bangakwazi futhi ukuhlinzeka amandla kagesi ngaphesheya kwekhebula kumadivayisi adinga lokho.
Zombili izinguqulo ezinamathebhu nezingenantambo zesezingeni le-USB likhona, nakuba kuphela i-wired version ehilela ama-USB namakhodi.
Yini Ongayifaka Ku-Port Port?
Izinhlobo eziningi zabathengi electronics zisekela ukuxhuma kwe-USB. Lezi zinhlobo zemishini zivame ukusetshenziselwa ukuxhumana nge-computer:
- Ama- adapters wenethiwekhi ye- USB
- Ukuxhumeka kwe-USB ebanzi kanye namaselula wokufinyelela kwe-intanethi
- Iphrinta ye-USB kufanele yabelwe kunethiwekhi yasendlini
Ukuze uthumele ifayela lekhompiyutha kuya kwekhompyutha ngaphandle kwenethiwekhi, amashayela we-USB abuye asetshenziselwe ukukopisha amafayela phakathi kwamadivayisi.
Ukusebenzisa i-USB Port
Xhuma amadivaysi amabili ngqo ngekhebula elilodwa le-USB ngokufaka ukuphela ngakunye kudoti le-USB. (Amanye amadivaysi afaka i-port eyodwa ye-USB, kodwa ungangeni amaphuzu womabili wekhebula kudivayisi efanayo, ngoba lokhu kungabangela umonakalo kagesi!)
Ungase uxoxe izintambo zibe yi-USB nganoma isiphi isikhathi kungakhathaliseki ukuthi amadivaysi abandakanyekayo avunyelwe noma avaliwe. Landela imiyalo enikeziwe ngemishini yakho ngaphambi kokuvula izintambo ze-USB. Kwezinye izimo, ukuvula ikhebula le-USB kusuka kudivayisi esebenzayo kungabangela
Amadivayisi amaningi we-USB angabuye axhumeke komunye nomunye usebenzisa ihabhu le-USB . Ihabhu le-USB lixhuma kudoti elilodwa le-USB futhi liqukethe amarekhodi angeziwe amanye amadivayisi ukuxhuma kamuva. Uma usebenzisa ihabhu le-USB, vula ikhebula elihlukile kudivayisi ngayinye bese uwaxhuma kubhubhu ngabanye.
Izinhlobo ze-USB-A, USB-B kanye ne-USB-C
Izinhlobo eziningana eziyinhloko zezakhiwo zangokwenyama zikhona zamathrekhi e-USB:
- I-USB-B (Thayipha B) : Lesi sikhangisi esingumxhwele cishe ubude buka-1.4 cm (9/16 in) ubude obungama-0.65 cm (1/4 in) ubude buvame ukutholakala kuma-routers, amakhompiyutha, amaphrinta namaduduzi wegeyimu. Izinti ze-USB zivame ukufaka izixhumi ze-USB-B nazo.
- I-USB-A (Thayipha A) : Okungajwayelekile okungekho uhlobo B, i-USB A amadivaysi acishe abe square futhi asetshenziselwa amagundane wired kanye namakhibhodi.
- I-USB Micro : Okubizwa ngokuthi yi- Micro USB izinguqulo zombili i-USB-A ne-USB-B nayo ikhona - izinguqulo ezincane kunabalingani bazo basekhaya, ethandwa kumadivayisi eselula. (Izinguquko ezindala kepha manje ezingaphelele "i-USB mini" zingatholakala nakwamanye amadivaysi amadala.)
- Uhlobo lwe-C C : Ngokulinganisa okungu-0.84 cm ngu-0.26cm, lesi simiso esisha senzelwe ukufaka esikhundleni se-A no-B ngamaphakheji amancane ukuze sisekele kangcono amafomu amafomu afanele amadivayisi eselula
Ukuxhuma idivaysi enomhlobo owodwa wechweba idivaysi enomunye uhlobo, sebenzisa nje uhlobo olufanele lwekhebula nge-interfaces efanele ekupheleni kwawo konke. Amakhodi we-USB akhiqizwa ukusekela zonke izinhlanganisela ezisekelwe izinhlobo kanye nezinketho zesilisa / zezinsikazi.
Izilinganiso ze-USB
Amadivayisi we-USB nezintambo zisekela izinguqulo eziningi zezinga le-USB kusuka ku-version 1.1 kuze kufike ku-version yamanje 3.1. Amathrekhi we-USB ahlanganisa izakhiwo zomzimba ezifanayo kungakhathaliseki ukuthi i-USB isekelwe kanjani.
I-USB Port ayisebenzi?
Akuwona konke okuhamba kahle lapho usebenza namakhompyutha. Kunezizathu ezihlukahlukene ukuthi i-port ye-USB ingayeka ngokuzumayo ukusebenza kahle. Nakhu okufanele ukwenze uma uhlangabezana nezinkinga.
Ezinye izindlela ze-USB
Amapayipi e-USB angenye kwezinye izingxenyana ze-serial kanye ezifanayo ezikhona kuma-PC amadala. Amaphakheji e-USB asekela ngokushesha kakhulu (ngokuvamile kaningi okungu-100x noma ngaphezulu) ukudluliswa kwedatha kune-serial noma parallel.
Ngezingcingo ze- computer , ama- port e-Ethernet ngezinye izikhathi asetshenziswa esikhundleni se-USB. Kwezinye izinhlobo zezingcingo zekhompiyutha , amachweba e-FIreWire nawo ngezinye izikhathi atholakalayo. Kokubili i-Ethernet ne-FireWire ingahlinzeka ngokushesha ngokushesha kune-USB, nakuba lezi zinkimbinkimbi zinganiki amandla nganoma yimuphi ucingo.
