ho ntseba Phapano e hlokomelehang haholo lipakeng tsa USB 2.0 le USB 3.0 le likarolo tsa bona tsa bohlokoa ka ho fetisisa.
the USB ke khutsufatso ea Universal Serial Bus. Ke sehokelo se sebelisetsoang ho hokahanya li-peripheral tse kang: toeba وline وmohatisi وli-hard drive khomphuteng ya hao.
e ntšitsoe USB 2.0 ka selemo 2000 Ke liphetolelo tse eketsehileng tsa USB e sebelisitsoeng ho fihlela joale.
e ntšitsoe USB 3.0 ka selemo 2008 Butle-butle o nka sebaka.
joalo ka seo USB 2.0 و USB 3.0 Ba na le sete e ikhethang ea likarolo. Ka hona, ka sehlooho sena, re tla tseba hammoho Liphapang tsohle pakeng tsa USB 2.0 و USB 3.0.
Phapang pakeng tsa USB 2.0 le USB 3.0
Ka mela e latelang, re tla u tseba Phapang pakeng tsa USB 2.0 le USB 3.0 Kahoo a re qaleng.
1. Ponahalo ea ’mele
- Lihokelo USB 2.0 e ntšo ka hare , Leha ho le joalo USB 3.0 blue ka hare.
- USB 2.0 e na le lithapo tse 4 tsa sehokelo , Leha ho le joalo USB 3.0 e na le lithapo tse 9 tsa sehokelo.
Ka hona, li-connectors USB 3.0 e kholo hofeta mokhanni USB 2.0. Ka hona, ho amohela lithapo tse eketsehileng.
Mme ka hona, Lihokelo tsa USB 3.0 li ke ke tsa sebelisoa le likou tsa USB 2.0.
2. Lebelo la ho fetisa
- fihla USB 2.0 lebelo la phetiso Ho leba Li-Mbps tse 480.
- fihla USB 3.0 lebelo la phetiso Ho leba 4.8 Gbps.
Ka hona USB 3.0 e potlakile ka makhetlo a 10 ho feta USB 2.0.
3. Ho lumellana ka morao
likou USB 3.0 Ka morao e tsamaellana. Kahoo, sesebelisoa se ka kopanngoa USB 2.0 boemakepe USB 3.0.
Leha ho le joalo, ha sesebelisoa se kopantsoe USB 3.0 boemakepe USB 2.0 , lebelo la phetiso ea data le tla lekanyetsoa ho USB 2.0 , e lekanang le hoo e ka bang Li-Mbps tse 480.
4. Tsamaiso ea matla
- USB 2.0 e fana ka matla a fihlang ho 500mA matla a merero ea hae.
- USB 3.0 e fana ka matla a fihlang ho 900mA matla a merero ea hae.
Sena se fella ka keketseho ea kakaretso ea phepelo ea matla ho tloha ho 2.5W ho ea ho 4.5W ho 5V.
Mme ka hona, Lisebelisoa tsa USB 3.0 li ka tjhaja kapele ha li hokahantsoe le likou tsa USB 3.0. joalo ka USB 3.0 e fana ka taolo e nepahetseng ea matla le ho eketsa phano ea motlakase. Le eena a ka khona Boloka matla ka ho khaola phepelo ea lisebelisoa tse sa sebetseng.
5. Bophahamo ba motlakase
- USB 2.0 Ke puisano ea halofo ea duplex, ho bolelang hore data e romelloa le ho amoheloa ka tsela e tšoanang.
Kahoo, USB 2.0 Ho romella data kapa ho amohela data feela ka nako e itseng , empa eseng ka bobeli. - USB 3.0 Ke puisano ea halofo ea duplex, ho bolelang hore e sebelisa litsela tse peli tse arohaneng tsa data tsa tsela e le 'ngoe. E 'ngoe ke ea ho romella data le e' ngoe bakeng sa ho amohela data.
Mme ka hona, USB 3.0 e na le bandwidth e fetang USB 2.0.
6. Lithapo tsa USB
- Lithapo tsa USB 3.0 li ka sebelisoa ho hokela likoung tsa USB 2.0 le ka tsela e fapaneng. Empa lisebelisoa tsa USB 3.0 li hloka feela likhoele tse 3.0.
Kahoo, ho bohlokoa hore o bapise thapo ea USB le mofuta oa boema-kepe ba USB. - e ka fihla Lithapo tsa USB 2.0 li bolelele ba limithara tse 5 ha e ntse e phahama Lithapo tsa USB 3.0 li bolelele ba limithara tse 3 Feela.
7. Theko
Lokisetsa Lisebelisoa tsa USB 2.0 li theko e tlase haholo ho feta lisebelisoa tsa USB 3.0. Sena se bakoa ke likarolo tse tsoetseng pele tseo e fanang ka tsona USB 3.0 , le ho haella ka hare USB 2.0.
Leha ho le joalo, Lisebelisoa tsa USB 3.0 li fana ka boleng ba chelete.
Mefuta ea USB
- USB1.0: E ts'ehetsa ho fihla ho li-peripheral tse 127 Phetiso ea data ho fihla ho 12 Mbps.
- USB2.0: E qalile ho hlahisoa ka selemo sa 2000 mme e tsejoa e le Hi-Speed USB. E tšehetsa lisebelisoa le likhoele USB 1.
- USB 3.0 أو SuperSpeedUSB: Ke phetolelo e ntlafalitsoeng ea USB 2 E ile ea hlahisoa ka lekhetlo la pele ka 2008.
- USB3.1: Phetolelo ea morao-rao ea USB , e tsejoang e le SuperSpeed + , ka lekhetlo la pele ka 2014.
- Kou ea USB ea Mofuta oa C: Ke plug e fetolehang ea 24-pin e hlahisitsoeng ka nako e le 'ngoe USB 3.1 Hoo e ka bang.
Qetello:
Tsena e ne e le tse ling Phapano e hlokomelehang lipakeng tsa USB 2.0 le USB 3.0. Joalokaha re boletse meleng e fetileng, melemo eo USB 3.0 e nang le eona e phahametse ea USB 2.0. Kahoo, re khothaletsa hore u khethe USB 3.0 ho feta USB 2.0.
Hape, USB 3.0 e sebetsa ka morao, ka hona, ha ua tlameha ho sebelisa sesebelisoa leha e le sefe se khethehileng ho hokela sesebelisoa sa USB 2.0 boema-kepeng ba USB 3.0, le ka tsela e fapaneng.
Haeba u na le lipotso mabapi le Phapang pakeng tsa USB 2.0 le USB 3.0 Re tsebise litlhalosong.
U kanna ua ba le tjantjello ea ho ithuta ka:
- Lisebelisoa tse 15 tse ntle ka ho fetisisa tsa cable OTG O tlameha ho ba tseba
- Phapang ke efe lipakeng tsa linotlolo tsa USB
- Phapano ke efe lipakeng tsa MTP, PTP, le USB Mass Storage?
- Tsela ea ho tima USB le ho hakolla molumo ho Windows
- Khoasolla mahala USB 2.0 Wireless 802.11n Driver bakeng sa Windows
Re tšepa hore u tla fumana sengoloa sena se le bohlokoa hore u se tsebe Phapang ea bohlokoa ka ho fetisisa lipakeng tsa USB 3.0 le USB 2.0. Fana ka maikutlo a hau le boiphihlelo le rona litlatsong.
