mundidziwe Kusiyana kwakukulu pakati pa USB 2.0 ndi USB 3.0 Awo zofunika kwambiri mbali.
a USB ndichidule cha Universal Serial Bus. Ndi mawonekedwe omwe amagwiritsidwa ntchito kulumikiza zida zotumphukira monga: الماوس وkiyibodi وchosindikizira وma hard drive ku kompyuta yanu.
wamasulidwa USB 2.0 mu chaka 2000 Ndilo mtundu wotchuka kwambiri wa . USB yogwiritsidwa ntchito mpaka pano.
wamasulidwa USB 3.0 mu chaka 2008 Pang’onopang’ono akutenga ulamuliro.
ngati kuti USB 2.0 و USB 3.0 Ali ndi mawonekedwe apadera. Chifukwa chake, kudzera m'nkhaniyi, tiphunzira Kusiyana konse pakati pa USB 2.0 و USB 3.0.
Kusiyana pakati pa USB 2.0 ndi USB 3.0
M’mizere yotsatirayi, tiphunzira za Kusiyana pakati pa USB 2.0 ndi USB 3.0 Choncho, tiyeni tiyambe.
1. Maonekedwe athupi
- zolumikizira USB 2.0 wakuda mkati , Pamene USB 3.0 ndi buluu mkati.
- USB 2.0 ili ndi cholumikizira mawaya 4 , Pamene USB 3.0 ili ndi cholumikizira mawaya 9.
Choncho, zolumikizira USB 3.0 wamkulu kuposa conductor USB 2.0. Momwemonso, kuti athetse mawaya owonjezera.
Chifukwa chake, Zolumikizira za USB 3.0 sizingagwiritsidwe ntchito ndi madoko a USB 2.0.
2. Kuthamanga liwiro
- kufikira Kuthamanga kwa USB 2.0 Kutsogolo 480 Mbps.
- kufikira Kuthamanga kwa USB 3.0 Kutsogolo 4.8 Gbps.
Choncho USB 3.0 imathamanga nthawi 10 kuposa USB 2.0.
3. Kugwirizana kumbuyo
madoko USB 3.0 Kumbuyo n'zogwirizana. Choncho, chipangizo akhoza kulumikizidwa USB 2.0 doko USB 3.0.
Komabe, polumikiza chipangizo USB 3.0 doko USB 2.0 , kuthamanga kwa data kudzakhala kokha pa liwiro USB 2.0 , yomwe ili pafupi 480 Mbps.
4. Kasamalidwe ka mphamvu
- USB 2.0 imapereka mphamvu mpaka 500mA mphamvu pa zida zake.
- USB 3.0 imapereka mphamvu mpaka 900mA mphamvu pa zida zake.
Izi zimapangitsa kuti mphamvu zonse ziwonjezeke kuchoka pa 2.5W kufika pa 4.5W pa 5V.
Chifukwa chake, Zida za USB 3.0 zitha kulipiritsidwa mwachangu zikalumikizidwa ndi madoko a USB 3.0. monga USB 3.0 imapereka kasamalidwe koyenera ka mphamvu ndikuwonjezera kuperekera mphamvu. Iyenso angathe Tetezani mphamvu pochepetsa kuperekedwa kwa zida zopanda ntchito.
5. Bandwidth
- USB 2.0 Ndi njira imodzi yolankhulirana, kutanthauza kuti deta imatumizidwa ndi kulandiridwa panjira yomweyo.
Choncho, akhoza USB 2.0 Kutumiza deta kapena kulandira deta panthawi inayake , koma si onse awiri. - USB 3.0 Ndi njira imodzi yolankhulirana, kutanthauza kuti imagwiritsa ntchito njira ziwiri zosiyana za njira imodzi. Imodzi ndiyo kutumiza deta ndipo ina ndiyo kulandira deta.
Chifukwa chake, USB 3.0 ili ndi bandwidth yochulukirapo kuposa USB 2.0.
6. Zingwe za USB
- Zingwe za USB 3.0 zitha kugwiritsidwa ntchito kulumikiza madoko a USB 2.0 ndi mosemphanitsa. Koma zida za USB 3.0 zimangofunika zingwe za 3.0.
Chifukwa chake, ndikofunikira kuti mufanane ndi chingwe cha USB ndi mtundu wa doko la USB. - akhoza kufika Utali wa chingwe cha USB 2.0 mpaka 5m pamene pamwamba Utali wa chingwe cha USB 3.0 mpaka 3m Basi.
7. Mtengo
Konzekerani Zida za USB 2.0 ndizotsika mtengo kwambiri kuposa zida za USB 3.0. Izi ndichifukwa cha zida zapamwamba zomwe zimapereka USB 3.0 , kutayika USB 2.0.
Komabe, Zida za USB 3.0 zimapereka mtengo wandalama.
Mitundu ya USB
- USB1.0: Imathandizira mpaka ma terminals 127 pamtengo Kutumiza kwa data mpaka 12Mbps.
- USB2.0: Idayambitsidwa koyamba mu 2000 ndipo imadziwika kuti Hi-Speed USB. Imathandizira zida ndi zingwe USB 1.
- USB 3.0 أو SuperSpeed USB: Ndi mtundu wowongoleredwa wa USB 2 Idayambitsidwa koyamba mu 2008.
- USB3.1: Mtundu waposachedwa wa USB , wotchedwa SuperSpeed + , kwa nthawi yoyamba mu 2014.
- Doko la USB Type C: Ndi pulagi yosinthika ya mapini 24 yomwe idayambitsidwa nthawi imodzi USB 3.1 Pafupifupi.
Pomaliza:
Awa anali ena Kusiyana kwakukulu pakati pa USB 2.0 ndi USB 3.0. Monga tanenera m'mizere yapitayi, zabwino zomwe USB 3.0 ili nazo kuposa za USB 2.0. Chifukwa chake, timalimbikitsa kusankha USB 3.0 pa USB 2.0.
Komanso, USB 3.0 ndi kumbuyo n'zogwirizana, motero, simuyenera kugwiritsa ntchito chida chilichonse chapadera kulumikiza USB 2.0 chipangizo ku doko USB 3.0, ndi mosemphanitsa.
Ngati muli ndi mafunso okhudza Kusiyana pakati pa USB 2.0 ndi USB 3.0 Tiuzeni mu ndemanga.
Mwinanso mungakhale ndi chidwi chophunzira za:
- 15 Zabwino Zogwiritsa Ntchito Chingwe OTG Muyenera kuwadziwa
- Kodi pali kusiyana kotani pakati pa makiyi a USB
- Kodi pali kusiyana kotani pakati pa MTP, PTP, ndi USB Mass Storage?
- Momwe mungazimitsire kulumikizana kwa USB ndikulumikiza mawu mu Windows
- Kutsitsa Kwaulere kwa USB 2.0 Wireless 802.11n Driver ya Windows
Tikukhulupirira kuti mwapeza kuti nkhaniyi ndi yothandiza kuti mudziwe Kusiyana kwakukulu pakati pa USB 3.0 ndi USB 2.0. Gawani malingaliro anu ndi zokumana nazo nafe mu ndemanga.
