Kumayambiriro kwa zipangizo zamakono, vuto lalikulu la wogwiritsira ntchito linali losavomerezeka kwambiri ndi zipangizo - madoko ambiri osiyana anali ndi udindo wogwirizanitsa ziwalo, zambiri zomwe zinali zovuta komanso zosadalirika. Njira yothetsera vutoli inali "basi yaikulu" kapena USB yaifupi. Kwa nthawi yoyamba doko latsopano linaperekedwa kwa anthu kumadera akutali chaka cha 1996. Mu 2001, mabotolo ndi makina akunja a USB 2.0 muyeso adayamba kupezeka kwa ogula, ndipo mu 2010, USB 3.0 inapezeka. Kotero kusiyana kotani pakati pa matekinoloje awa ndi chifukwa chiyani onse akufunabe?
Kusiyana pakati pa miyezo ya USB 2.0 ndi 3.0
Choyamba, tiyenera kukumbukira kuti ma doko onse a USB akugwirizana. Izi zikutanthawuza kuti kugwirizanitsa chipangizo chochedwa pang'onopang'ono ndi zotchinga ndi kotheka, koma liwiro la kusinthanitsa deta lidzakhala lochepa.
"Dziwani" mawonekedwe owonetsera akhoza kukhala owonetsera - mu USB 2.0, mkatikati mwawonekedwe pamiyala yoyera, ndi USB 3.0 - mu buluu.

Kuonjezera apo, zingwe zatsopano sizinayi, koma mipanda isanu ndi itatu, zomwe zimapangitsa kuti zikhale zochepa komanso zosasinthika. Kumbali imodzi, izi zimapangitsa kuti zipangizo zizigwiritsidwa ntchito, zimapangitsa kuti pakhale njira zowunikira deta, kumbali inayo - kumawonjezera mtengo wa chingwe. Kawirikawiri, matepi a USB 2.0 amakhala 1.5-2 nthawi yaitali kuposa achibale awo ofulumira. Pali kusiyana kwa kukula ndi kusinthika kwa mawonekedwe ofanana. Choncho, USB 2.0 yagawanika:
- mtundu A (wamba) - 4 × 12 mm;
- mtundu B (wamba) - 7 × 8 mm;
- mtundu A (Mini) - 3 × 7 mm, trapezoid ndi ngodya zozungulira;
- Lembani B (Mini) - 3 × 7 mm, trapezoidal ndi mavola abwino;
- mtundu A (Micro) - 2 × 7 mm, timakona ting'onoting'ono;
- Lembani B (Micro) - 2 × 7 mm, timakona ting'onoting'ono ndi makona ozungulira.
Mu zipangizo za makompyuta, kawirikawiri mtundu wa USB mtundu A umagwiritsidwa ntchito, mu zipangizo zamagetsi - Mtundu wa B Mini ndi Micro. Maofesi a USB 3.0 ndi ovuta:
- mtundu A (wamba) - 4 × 12 mm;
- mtundu B (wamba) - 7 × 10 mm, mawonekedwe ovuta;
- Lembani B (Mini) - 3 × 7 mm, trapezoidal ndi mavola abwino;
- Lembani B (Micro) - 2 × 12 mm, timakona ting'onoting'ono ndi makona ozungulira ndi zolemba;
- Lembani C - 2.5 × 8 mm, timakona ting'onoting'ono ndi makona ozungulira.
Lembani A lidalibebe mu makompyuta, koma mtundu wa C umakhala wotchuka kwambiri tsiku ndi tsiku. Adaptata pa miyezo imeneyi akuwonetsedwa mu chiwerengerocho.

Tchati: Zomwe zili zenizeni zokhudzana ndi zida za madoko a wachiwiri ndi wachitatu
| Chizindikiro | USB 2.0 | USB 3.0 |
| Kuchuluka kwa chiwerengero cha kusintha kwa deta | 480 Mbps | 5 Gbps |
| Zolemba zenizeni za data | mpaka 280 Mbps | mpaka 4.5 Gbit / s |
| Maxim wamakono | 500 mamita | 900 mamita |
| Mawindo a Windows omwe amathandiza muyezo | ME, 2000, XP, Vista, 7, 8, 8.1, 10 | Vista, 7, 8, 8.1, 10 |
Pakalipano, ndikumayambiriro kwambiri kuti mulembe USB 2.0 kuchokera ku akaunti - muyezo umenewu umagwiritsidwa ntchito kwambiri kugwirizanitsa makina, mbewa, makina osindikizira, makina osakaniza ndi zipangizo zina zakunja, zomwe zimagwiritsidwa ntchito pamagetsi. Koma pofuna kuyendetsa phokoso ndi maulendo apakati, pamene kuwerenga ndi kulemba mwamsanga ndizofunikira, USB 3.0 ndi yabwino. Ikuthandizani kuti mugwirizanitse zipangizo zambiri ku kampu imodzi ndikupaka ma batri mofulumira chifukwa cha mphamvu zamakono.
