Ekuqaleni kobuchwepheshe bekhompyutha, enye yezinkinga eziyinhloko zomsebenzisi kwakuhambisana nokungahambisani kwamadivaysi - amachweba amaningi angenawo wonke amazwe ayebhekene nokuxhuma amakhemikhali, iningi lawo lalingamathemba aphansi futhi aphansi. Isixazululo sasiwukuthi "ibhasi elijwayelekile jikelele" noma i-USB emfushane. Isikhathi sokuqala ichweba elisha linikezwe emphakathini ekude nango-1996. Ngo-2001, amabhodi wamabhodi namadivayisi wangaphandle wezinga le-USB 2.0 latholakala kubathengi, futhi ngo-2010, i-USB 3.0 yabonakala. Ngakho-ke umehluko phakathi kwalabu buchwepheshe futhi kungani kokubili kusadingeka?
Umehluko phakathi kwamazinga we-USB 2.0 no-3.0
Okokuqala, kubalulekile ukuthi zonke izingodo ze-USB zihambisane. Lokhu kusho ukuthi ukuxhuma idivayisi esheshayo echwebeni elisheshayo futhi ngokuphambene nalokho kungenzeka, kodwa ijubane lokushintshaniswa kwedatha lizoba elincane.
Ungakwazi "ukuqaphela" izinga lokuxhuma elibonakalayo - i-USB 2.0, ingaphakathi langaphakathi lidwetshiwe elimhlophe, ne-USB 3.0 - eluhlaza okwesibhakabhaka.

Ngaphezu kwalokho, izintambo ezintsha azizona ezine, kodwa izintambo eziyisishiyagalombili, ezenza zibe zikhudlwana futhi zingahambisani nezimo. Ngakolunye uhlangothi, lokhu kwandisa ukusebenza kwamadivayisi, kuthuthukisa imingcele yokudlulisela idatha, ngakolunye uhlangothi - kwandisa izindleko zekhebula. Ngokuvamile, amakhodi e-USB 2.0 aphindwe izikhathi ezingu-1.5-2 kunezihlobo zabo "ezisheshayo". Kukhona umehluko ngobukhulu nokucushwa kwezinhlobo ezifanayo zezixhumi. Ngakho, i-USB 2.0 ihlukaniswe yaba:
- uhlobo A (evamile) - 4 × 12 mm;
- uhlobo B (evamile) - 7 × 8 mm;
- uhlobo A (Mini) - 3 × 7 mm, i-trapezoid enezingqimba ezizungezile;
- Thetha B (Mini) - 3 × 7 mm, trapezoidal enezingalo ezilungile;
- uhlobo A (Micro) - 2 × 7 mm, umxhwele;
- Thayipha B (Micro) - 2 × 7 mm, i-rectangular enezingqimba ezizungezile.
Ezingxenyeni zekhompiyutha, i-USB evamile Ihlobo A isetshenziswa kaningi, kumagadgets ephathekayo - Thayipha i-Mini Mini ne-Micro. Ukuhlukaniswa kwe-USB 3.0 kuyinkimbinkimbi:
- uhlobo A (evamile) - 4 × 12 mm;
- uhlobo B (evamile) - 7 × 10 mm, isimo esiyinkimbinkimbi;
- Thetha B (Mini) - 3 × 7 mm, trapezoidal enezingalo ezilungile;
- Thayipha B (Micro) - 2 × 12 mm, i-rectangular enezingqimba ezizungezile kanye nohlaka;
- Thayipha i-C - 2.5 × 8 mm, i-rectangular enezingqimba ezizungezile.
Uhlobo lwe-A lusekhona nakakhulu kuma-computer, kodwa Uhlobo C luyawuthandwa kakhulu nsuku zonke. I-adapter yalezi zindinganiso iboniswa kumfanekiso.

Ithebulethi: Ulwazi oluyisisekelo mayelana namakhono amachweba wesizukulwane sesibili nesithathu
| Inkomba | I-USB 2.0 | I-USB 3.0 |
| Inani lokudluliswa kwedatha elikhulu | 480 Mbps | 5 Gbps |
| Isilinganiso sedatha yangempela | kufika ku-280 Mbps | kufika ku-4.5 Gbit / s |
| I-Max yamanje | 500 mA | 900 mA |
| Izilinganiso ze-Windows ezisekela izinga | ME, 2000, XP, Vista, 7, 8, 8.1, 10 | Vista, 7, 8, 8.1, 10 |
Kuze kube manje, kusencane kakhulu ukuthi ubhale i-USB 2.0 kusuka kuma-akhawunti - lesi simiso sisetshenziselwa ukuxhuma ikhibhodi, igundane, amaphrinta, amaskena kanye namanye amadivayisi angaphandle, asetshenziswe kumajethi weselula. Kodwa ngenxa yokushayela okusheshayo kanye nokushayela kwangaphandle, lapho ufunda nokubhala ngezinga eliyisisekelo, i-USB 3.0 ifaneleka kangcono. Ibuye ikuvumele ukuthi uxhume amadivaysi amaningi kwenye ihabhu elilodwa futhi ulayishe amabhethri ngokushesha ngenxa yamandla amakhulu wamanje.
