Kumayambiriro kwa ukadaulo wamakompyuta, vuto limodzi lalikulu lomwe wogwiritsa ntchito anali kugwiritsidwa ntchito kosayenera kwazipangizo - madoko ambiri opanga maukadaulo anali ndi ntchito yolumikiza ziphuphu, zomwe zambiri zinali zodalirika komanso zodalirika. Yankho lake anali "konsekonse positi basi" kapena, mwachidule, USB. Kwa nthawi yoyamba, doko latsopanoli linaperekedwa kwa anthu onse mmbuyomo mu 1996. Mu 2001, ma boardboard amayi ndi zida za USB 2.0 zinayamba kupezeka kwa makasitomala, ndipo mu 2010 USB 3.0 idawonekera. Nanga pali kusiyana kotani pakati pa matekinoloje awa ndipo chifukwa chiyani onse amafunabe?
Kusiyana pakati pa USB 2.0 ndi 3.0
Choyamba, ndikofunikira kudziwa kuti madoko onse a USB amagwirizana. Izi zikutanthauza kuti kulumikiza chipangizocho pang'onopang'ono padoko lokhazikika komanso mosavomerezeka ndikutheka, koma mtengo wosinthitsa deta udzakhala wochepa.
Mutha "kuzindikira" muyezo wa cholumikizira chowoneka - ndi USB 2.0 mkati wamtambo utayera, ndi USB 3.0 - buluu.

Kuphatikiza apo, zingwe zatsopanozi sizikhala ndi zinayi, koma zingwe zisanu ndi zitatu, zomwe zimapangitsa kuti zikhale zokulirapo komanso zosasunthika. Kumbali imodzi, izi zimawonjezera magwiridwe antchito a zida, kukonza magawo a kusintha kwa data, ndipo inayo, imakweza mtengo wa chingwe. Monga lamulo, zingwe za USB 2.0 ndizotalika 1.5-2 kuposa achibale awo "achangu". Pali zosiyana pamlingo ndi kasinthidwe ka mitundu yofananira yolumikizira. Chifukwa chake, USB 2.0 imagawidwa kukhala:
- lembani A (zabwinobwino) - 4 × 12 mm;
- lembani B (yabwinobwino) - 7 × 8 mm;
- lembani A (Mini) - 3 × 7 mm, trapezoidal wokhala ndi ngodya zozungulira;
- lembani B (Mini) - 3 × 7 mm, trapezoidal ndi ngodya zabwino;
- lembani A (Micro) - 2 × 7 mm, amakona atatu;
- mtundu B (Micro) - 2 × 7 mm, amakona anayi ndi ngodya zozungulira.
M'makompukutu apakompyuta, USB Mtundu A wamasiku onse umagwiritsidwa ntchito kwambiri, zamagetsi zam'manja - Type B Mini ndi Micro. Kugawidwa kwa USB 3.0 kumakhalanso kovuta:
- lembani A (zabwinobwino) - 4 × 12 mm;
- lembani B (yabwinobwino) - 7 × 10 mm, mawonekedwe ovuta;
- lembani B (Mini) - 3 × 7 mm, trapezoidal ndi ngodya zabwino;
- lembani B (Micro) - 2 × 12 mm, amakona anayi okhala ndi ngodya komanso zokupumira;
- mtundu C - 2.5 × 8 mm, amakona anayi ndi ngodya zozungulira.
Mtundu A udakalipo m'makompyuta, koma mtundu C ukutchuka kwambiri tsiku lililonse. Ma adapter a miyezo awa akuwonetsedwa mu chithunzi.

Gome: Chidziwitso Choyambira pa Kukwanitsa Kwachiwiri ndi Kwachitatu Kukula
| Chizindikiro | USB 2.0 | USB 3.0 |
| Mlingo wapamwamba kwambiri | 480 Mbps | 5 Gbps |
| Mtengo Wowerengeka Weniweni | mpaka 280 Mbps | mpaka 4,5 Gbps |
| Pazambiri pano | 500 mA | 900 mA |
| Mitundu ya Windows | INE, 2000, XP, Vista, 7, 8, 8.1, 10 | Vista, 7, 8, 8.1, 10 |
Ndili m'mawa kwambiri kulemba USB 2.0 kuchokera ku maakaunti - mulingo uwu umagwiritsidwa ntchito kwambiri kulumikiza kiyibodi, mbewa, osindikiza, masikono, ndi zida zina zakunja, ndipo umagwiritsidwa ntchito pazida zamagetsi. Koma pagalimoto zowongolera ndi ma drive akunja, kuthamanga ngati kuwerenga ndi kulemba ndikofunikira, USB 3.0 ndiyabwino. Zimakupatsaninso mwayi wolumikizira zida zambiri kuzinthu chimodzi ndikuyika betri mwachangu chifukwa champhamvu kwambiri pakalipano.
