kusvika pakundiziva Misiyano inonyanya kuzivikanwa pakati pe USB 2.0 uye USB 3.0 uye maitiro avo akakosha.
iyo USB chidimbu che Universal Serial Bus. Iyo interface inoshandiswa kubatanidza peripherals senge: mbeva وkeyboard وprinter وhard drives kukombiyuta yako.
asunungurwa USB 2.0 mugore 2000 Ndiyo yakawanda shanduro dze USB kushandiswa kusvika zvino.
asunungurwa USB 3.0 mugore 2008 Ari kutora zvishoma nezvishoma.
saizvozvo USB 2.0 و USB 3.0 Vane seti yakasiyana yezvimiro. Nokudaro, kuburikidza nechinyorwa chino, tichasvika pakuziva pamwe chete Misiyano yese pakati pe USB 2.0 و USB 3.0.
Musiyano uripo pakati pe USB 2.0 uye USB 3.0
Kuburikidza nemitsetse inotevera, tichasvika pakukuzivai Kusiyana pakati pe USB 2.0 ne USB 3.0 Saka ngatitangei.
1. Chitarisiko chomuviri
- Connectors USB 2.0 nhema mukati , Panguva USB 3.0 yebhuruu mukati.
- USB 2.0 ine 4 mawaya ekubatanidza , Panguva USB 3.0 ine 9 mawaya ekubatanidza.
Saka, zvibatanidza USB 3.0 mukuru kupfuura conductor USB 2.0. Saka nekudaro, kugarisa mamwe waya.
Uye naizvozvo, USB 3.0 connectors haigoni kushandiswa ne USB 2.0 ports.
2. Kutamisa kasi
- kusvika USB 2.0 yekumhanyisa kumhanya Toward 480 Mbps.
- kusvika USB 3.0 yekumhanyisa kumhanya Toward 4.8 Gbps.
Naizvozvo USB 3.0 inomhanya zvakapetwa kagumi pane USB 10.
3. Kudzokera shure kugarisana
ports USB 3.0 Kumashure kunoenderana. Saka, mudziyo unogona kubatanidzwa USB 2.0 port USB 3.0.
Zvisinei, kana mudziyo wabatanidzwa USB 3.0 port USB 2.0 , kumhanya kwekufambisa data kuchaganhurwa kune USB 2.0 , izvo zvinoita approx 480 Mbps.
4. Kutarisira simba
- USB 2.0 inopa kusvika ku500mA simba simba pamifungo yake.
- USB 3.0 inopa kusvika ku900mA simba simba pamifungo yake.
Izvi zvinoguma nekuwedzera kwesimba rose rekupa kubva pa2.5W kuenda ku4.5W pa5V.
Uye naizvozvo, USB 3.0 zvishandiso zvinogona kubhadharisa nekukurumidza kana zvakabatana ne USB 3.0 ports. as USB 3.0 inopa hutongi hwesimba hunoshanda uye inowedzera simba rekutumira. Anogonawo Chengetedza simba nekucheka chinopihwa kune zvishandiso zvisina basa.
5. Bandwidth
- USB 2.0 Ihafu-duplex kutaurirana, zvichireva kuti data inotumirwa uye inogamuchirwa pamusoro penzira imwe chete.
Saka, USB 2.0 Kutumira data kana kugamuchira data chete pane imwe nguva , asi kwete ose ari maviri. - USB 3.0 Ihafu-duplex kutaurirana, zvichireva kuti inoshandisa nzira mbiri dzakaparadzana-imwe nzira yedata. Imwe yekutumira data uye imwe yekugamuchira data.
Uye naizvozvo, USB 3.0 ine bandwidth yakawanda kupfuura USB 2.0.
6. USB tambo
- USB 3.0 tambo dzinogona kushandiswa kubatanidza kune USB 2.0 ports uye zvinopesana. Asi USB 3.0 zvishandiso zvinongoda tambo 3.0 chete.
Nokudaro, zvakakosha kuti uenzanise tambo ye USB kune shanduro yechiteshi che USB. - anogona kusvika Matambo e USB 2.0 akareba mamita mashanu apo kumusoro Matambo e USB 3.0 akareba mamita mashanu Just.
7. Mutengo
Gadzirira USB 2.0 zvishandiso zvakachipa zvakanyanya pane USB 3.0 zvishandiso. Izvi zvinokonzerwa nemhando yepamusoro yainopa USB 3.0 , uye kushaikwa mukati USB 2.0.
Zvisinei, USB 3.0 zvishandiso zvinopa kukosha kwemari.
USB mhando
- USB1.0: Inotsigira kusvika ku127 peripherals Kuendesa data kusvika ku12 Mbps.
- USB2.0: Yakatanga kuunzwa mugore ra2000 uye inozivikanwa se Hi-Speed USB. Inotsigira zvishandiso netambo USB 1.
- USB 3.0 أو SuperSpeed USB: Ishanduro yakavandudzwa ye USB 2 Yakatangwa muna 2008.
- USB3.1: Iyo yazvino vhezheni ye USB , anozivikanwa sa SuperSpeed + , kekutanga muna 2014.
- USB Type C port: Iyo inodzoreredzwa 24-pini plug yakaunzwa panguva imwe chete USB 3.1 Anenge.
Mhedziso:
Ava vaive vamwe Misiyano inoonekwa pakati pe USB 2.0 uye USB 3.0. Sezvatakataura mumitsetse yapfuura, mabhenefiti ane USB 3.0 akakwirira kune ayo e USB 2.0. Saka, isu tinokurudzira kuti usarudze USB 3.0 pane USB 2.0.
Zvakare, USB 3.0 inodzokera kumashure inoenderana, saka, haufanirwe kushandisa chero chishandiso chakakosha kubatanidza USB 2.0 mudziyo kune USB 3.0 port, uye zvinopesana.
Kana uine chero mibvunzo maererano Musiyano uripo pakati pe USB 2.0 uye USB 3.0 Tizivise mumashoko.
Iwe unogona zvakare kuve unofarira kudzidza nezve:
- 15 yakanakisa tambo inoshandisa OTG Unofanira kuvaziva
- Ndeupi musiyano uripo pakati pemakiyi e USB
- Ndeupi musiyano uripo pakati peMTP, PTP, uye USB Mass Storage?
- Maitiro ekudzima USB kubatanidza uye kubvisa toni muWindows
- Yemahara Dhawunirodha USB 2.0 Wireless 802.11n Driver yeWindows
Tinovimba iwe unowana ichi chinyorwa chinobatsira iwe kuti uzive Misiyano yakakosha pakati pe USB 3.0 uye USB 2.0. Goverana zvaunofunga uye ruzivo nesu mune zvakataurwa.
