Konke okudingeka ukwazi nge-Universal Serial Bus, i-USB
I-USB, ifushane ku-Universal Serial Bus, uhlobo olujwayelekile lokuxhumana kwezinhlobo eziningi zamadivayisi.
Ngokuvamile, i-USB ibhekisela ezinhlotsheni zezintambo nezixhumi ezisetshenziselwa ukuxhuma lezi zinhlobo eziningi zamadivayisi angaphandle kumakhompyutha.
Okuningi mayelana ne-USB
Isilinganiso se-Universal Serial Bus siphumelele kakhulu. Amathrekhi we-USB namakhodi asetshenziselwa ukuxhuma i-hardware njengamaphrinta, ama-scanners, ama- keyboards , amagundane , ama- flash drive , izinkinobho zangaphandle ezimbi , izinjabulo, amakhamera, nokunye okuningi kumakhompyutha azo zonke izinhlobo, kufaka phakathi ama-desktops, amaphilisi , i-laptops, netbooks, njll.
Eqinisweni, i-USB iye yavame kakhulu ukuthi uzothola uxhumano olutholakalayo cishe noma iyiphi idivayisi efana nekhompyutha njengama-console wegeyimu yevidiyo, imishini yomsindo wekhaya / ngisho nemikhumbi eminingi.
Amadivayisi amaningi aphathekayo, njenge-Smartphones, abafundi be-ebook, nezibhebhe ezincane, sebenzisa i-USB ngokuyinhloko ukushaja. Ukushaja kwe-USB sekuvame kakhulu kangangokuthi manje kulula ukuthola izindawo zokufakelwa kagesi ezishintshayo ezitolo zokuthuthukiswa ekhaya kanye namaphakheji e-USB azakhele, enganaki isidingo se-adaptha yamandla we-USB.
Izinguqulo ze-USB
Kube khona izindinganiso ezintathu ezinkulu ze-USB, 3.1 njengeyona entsha:
- I-USB 3.1: Ebizwa ngokuthi i- Superspeed + , i-USB 3.1 yamadivayisi afanelekayo adlulisela idatha ku-10 Gbps (10,240 Mbps).
- I-USB 3.0 : Ebizwa ngokuthi i- SuperSpeed USB , i-USB 3.0 yekhompyutha ehambisanayo ingafinyelela isilinganiso esiphezulu sokudlulisela ama-5 Gbps (5,120 Mbps).
- I-USB 2.0 : Ukubizwa nge -Speed Speed Speed , amadivayisi ahambisana ne-USB 2.0 angafinyelela izinga eliphezulu lokudlulisela ama-480 Mbps.
- I-USB 1.1 : Ebizwa nge- USB Speed Speed , amadivaysi e-USB 1.1 angafinyelela izinga eliphezulu lokudlulisa lama-12 Mbps.
Amadivayisi amaningi we-USB namakhodi namuhla anamathele ku-USB 2.0, nenombolo ekhulayo ibe yi-USB 3.0.
Okubalulekile: Izingxenye zesistimu exhunyiwe kwe-USB, kufaka phakathi umphathi (njengekhompyutha), ikhebula, kanye nedivayisi, bonke bangakwazi ukusekela amazinga e-USB ahlukene uma nje ehambisana ngokomzimba. Noma kunjalo, zonke izingxenye kumele zisekele izinga elifanayo uma ufuna ukuthi lifinyelele izinga eliphezulu lwedatha elingenzeka.
I-USB Connectors
Kunezixhumi eziningi ezixhumi ze-USB, zonke esichaza ngezansi. Bheka Ishadi lethu lokuvumelanisa ngokomzimba le-USB elibhekiselwe ekhasini elilodwa lalokho okuhambisana nalokho.
Ithiphu: Isixhumi sesilisa ku-cable noma flash drive ngokuvamile sibizwa ngokuthi ipulaki . Isixhumi sesifazane kudivayisi, ikhompuyutha, noma ikhebula lesandiso ngokuvamile libizwa ngokuthi i- receptacle .
- Uhlobo lwe-C C : Okuvame ukubhekwa njenge- USB-C , lawa ma-plugs kanye nezintambo ziyi-rectangular shape kanye nezingxenyana ezine ezizungezile. Ama-plug kanye nezintambo ze-USB kuphela ze-USB 3.1 (futhi kanjalo nezintambo) zikhona kepha ama-adapters okuhambisana nokubuyela emuva nge-USB 3.0 no-2.0 izixhumi ziyatholakala.
- Uhlobo lwe-A A : Okubizwa ngokusemthethweni ngokuthi i- USB Standard-A , lawa ma-plugs kanye nezintambo ziyi-rectangular shape futhi yizixhumi ezibonakala kakhulu ze-USB. I-USB 1.1 Uhlobo A, i-USB 2.0 Uhlobo A kanye ne-USB 3.0 Uhlobo lwe-plug kanye nezintambo zihambisana ngokomzimba.
- Uhlobo lwe-USB B : Ngokusemthethweni okuthiwa i- USB Standard-B , lawa ma-plugs kanye nezindwangu zenziwe ngesigcawu nge-notch eyengeziwe ngaphezulu, ebonakala kakhulu kuma-connectors we-USB 3.0 we-B. I-USB 1.1 Uhlobo B no-USB 2.0 Uhlobo lwe-plugs B oluhambisana ngokomzimba ne-USB 3.0 Uhlobo lweB B kodwa ama-plug USB 3.0B B awuhambisani ne-USB 2.0 Uhlobo B noma i-USB 1.1 Uhlobo lweB B.
- Isixhumi se-Powered-B se-USB siphinde sichazwe kumgomo we-USB 3.0. Lesi sakhiwo sisebenza ngokomzimba nge-USB 1.1 ne-USB 2.0 Standard-B plugs, kanye nama-plug-in USB 3.0 Standard-B ne-Powered-B.
- I-USB Micro-A: I-USB 3.0 Micro-A i-plugs ibonakala njengama-plugs amabili angama-rectangular ahlangene ndawonye, eyodwa kancane kakhulu kunomunye. I-USB 3.0 Micro-A plugs ihambisana kuphela ne-USB 3.0 Micro-AB izithandwa.
- Ama-plugs we-USB 2.0 Amakhamera amancane ayingcosana futhi angama-rectangular, afana ngezindlela eziningi i-plug USB ye-USB ye-shrunken. I-USB Micro-A plugs ihambisana ngokomzimba kokubili i-USB 2.0 ne-USB 3.0 Micro-AB.
- I-USB Micro-B: I-USB 3.0 ye-Micro-B plugs ibonakala ifana ne-USB 3.0 Micro-A plugs lapho ibonakala njengabantu ababili, kodwa ixhunyiwe, ama-plugs. Ama-plug-USB angu-3.0 3.0 we-micro-B ahambisana nama-USB 3.0 Micro-B kanye nezintambo ze-USB 3.0 Micro-AB.
- Ama-plugs we-USB 2.0 ama-micro-B amancane kakhulu futhi angama-rectangular kodwa amakhonksi amabili kwenye yezinhlangothi ezide asetshenziswe. Amaphakheji e-Micro-B e-USB ahambisana nomzimba we-USB 2.0 Micro-B kanye ne-Micro-AB, kanye ne-USB 3.0 Micro-B kanye ne-Micro-AB.
- I-USB Mini-A: Ipulagi ye-USB 2.0 Mini-A inemibhoshongo kodwa inhlangothi eyodwa iningi. Ama-plugs we-USB Mini-A ahambisana kuphela nezintambo ze-USB Mini-AB. Ayikho isikhombisi se-USB 3.0 Mini-A.
- I-USB Mini-B: Ipulagi ye-USB 2.0 Mini-B iyimidwebo emigqumeni ngendwangu encane ngakolunye uhlangothi, cishe ibukeka njengengcezu yesinkwa esuliwe lapho ibukeka ikhanda. Amaphakheji e-Mini-B e-USB ahambisana nomzimba we-USB 2.0 Mini-B kanye ne-Mini-AB. Ayikho isikhombisi se-USB 3.0 Mini-B.
Qaphela: Ukuze nje kucace, awekho USB Micro-A noma USB Mini-A izitsha , kuphela ama-USB Micro-A kanye nama-USB Mini-A plugs . Lezi "plugs" ezihambisana ne-AB "izithiyo.
