Kodi pali kusiyana kotani pakati paUSB 3.1 Gen 1ndiGen 2?
USB 3.1 Gen 1ndiGen 2Kusanthula Kusiyana Kofunika Pakati pa Miyezo Iwiriyi
Mukamagula zipangizo zosungiramo zinthu zakunja, malo osungiramo zinthu, kapena ma laputopu, mitundu ya ma USB interfaces nthawi zambiri imakhala yosokoneza, makamaka pamene mawu ngatiUSB 3.1 Gen 1ndiGen 2amapezeka kawirikawiri. Ngakhale kuti onse awiri ndi aUSB 3.1Mu banja lokhazikika, pali kusiyana kwakukulu pa magwiridwe antchito ndi momwe amagwiritsidwira ntchito. Nkhaniyi ifufuza kusiyana kwakukulu pakati pa mfundo ziwirizi kuti ikuthandizeni kusankha bwino.
Kusiyana kwa Liwiro: Kusiyana Kwambiri
Liwiro losamutsa lapamwamba kwambiri la chiphunzitso chaUSB 3.1 Gen 1(poyamba linkadziwika kutiUSB 3.0) ndi mpaka 5 Gbps (pafupifupi 625 MB/s). Liwiro limeneli ndi lokwanira kugwiritsidwa ntchito tsiku ndi tsiku, monga kulumikiza mbewa, makiyibodi, ma printers, kapena kusamutsa mafayilo ang'onoang'ono monga zikalata ndi nyimbo.
USB 3.1 Gen 2, kumbali ina, imawirikiza kawiri malire apamwamba awa ku10 Gbps(pafupifupi 1250 MB/s). Izi zikutanthauza kuti potumiza mafayilo akuluakulu, monga mavidiyo a 4K, zithunzi za RAW, kapena ma phukusi akuluakulu oyika masewera, nthawi yofunikira idzachepetsedwa kwambiri. Mwachitsanzo, kutumiza fayilo ya kanema ya 50GB 4K, Gen 2 ikhoza kusunga pafupifupi theka la nthawi poyerekeza ndi Gen 1.
Maziko Aukadaulo ndi Ndondomeko Zolembera Makhodi
Kusiyana kwa liwiro kuli mu magwiridwe antchito a njira zolembera ma code.USB 3.1 Gen 1imagwiritsa ntchito njira yolembera ma code ya 8b/10b, zomwe zikutanthauza kuti ma bits 8 okha mwa ma bits 10 aliwonse omwe amatumizidwa ndi deta yeniyeni, yokhala ndi mphamvu ya pafupifupi 80%. Chifukwa chake, bandwidth yeniyeni yogwira ntchito ya 5 Gbps raw rate ndi pafupifupi 4 Gbps.
USB 3.1 Gen 2Kukweza ku dongosolo lolemba ma code la 128b/132b logwira ntchito bwino, kuonjezera mphamvu kufika pa 97%, kulola kuti liwiro la 10 Gbps likhale lopanda mphamvu lipereke bandwidth yogwira ntchito bwino kwambiri. Kusintha kumeneku sikungowonjezera liwiro komanso kumachepetsa nthawi yotumizira mauthenga.
Mawonekedwe Akuthupi ndi Kugwirizana
Ndikofunika kuzindikira kuti zonse ziwiriUSB 3.1 Gen 1ndiGen 2akhoza kugwiritsa ntchito mitundu yofanana ya mawonekedwe, kuphatikizapo:
Mtundu-A (mawonekedwe ozungulira ofanana)
Mtundu-B (womwe umagwiritsidwa ntchito kwambiri mu ma printer ndi zipangizo zina)
Mtundu-C (mawonekedwe ozungulira osinthika)
USB 3.1 A mpaka Micro B(yomwe imagwiritsidwa ntchito kwambiri mu ma hard drive akunja ndi zida zina zakale za Android)
Ndikofunika kwambiri kuzindikira kutiMtundu wa USB Cndi mawonekedwe a mawonekedwe, osati muyezo wa liwiro. Mawonekedwe a Mtundu-C angathandizeUSB 3.1 Gen 1, Gen 2, kapena ngakhale protocol ya Thunderbolt 3. Chifukwa chake, liwiro la kutumiza silingadziwike kokha ndi mawonekedwe a mawonekedwe. Mwachitsanzo, aUSB C kupita ku USB AChingwe chingakhale ndi liwiro lenileni lochepetsedwa ndi miyezo ya ma interfaces kumapeto onse awiri ndi mtundu wa chingwecho, chomwe chingakhale cha Gen 1 cha 5 Gbps kapena Gen 2 cha 10 Gbps.
Mphamvu Yotulutsa Mphamvu
Ponena za magetsi, pansi paUSB 3.1 Gen 1muyezo, mawonekedwewa amatha kupereka mphamvu yokwana 4.5W (5V/0.9A). Mawonekedwe a Gen 2, akagwiritsidwa ntchito ndi protocol ya USB Power Delivery (PD), amatha kuthandizira magetsi okwana 100W (20V/5A), omwe ndi okwanira kuchajitsa ma laputopu ambiri ndi kupatsa mphamvu ma peripherals othamanga kwambiri. Tiyenera kudziwa kuti mukamagwiritsa ntchitoChingwe cha USB 3.1 A kupita ku Micro BKuti mulumikize zipangizo, mphamvu yamagetsi nthawi zambiri imakhala yochepa chifukwa cha zofunikira za doko la Micro B, ndipo nthawi zambiri mphamvu yamagetsi imakhala yotsika.
Malangizo Othandiza Ogwiritsira Ntchito
SankhaniUSB 3.1 Gen 1: Ndi yoyenera kulumikiza zida zonse zolumikizira (makiyibodi, mbewa, osindikiza), kusamutsa zikalata za tsiku ndi tsiku, kapena ngati cholumikizira choyatsira mafoni. Kwa ogwiritsa ntchito omwe ali ndi bajeti yochepa kapena omwe amafunikira zochepa, zida zochokera ku Gen 1 zimapereka phindu labwino. Mwachitsanzo, kuyika hard drive yakale yam'manja ndi muyezoChingwe cha USB 3.1 A kupita ku Micro B, liwiro la Gen 1 nthawi zambiri limakhala lokwanira.
SankhaniUSB 3.1 Gen 2Ngati nthawi zambiri mumafunika kusamutsa mafayilo akuluakulu (monga kusintha makanema, kupanga masewera), kulumikiza ma drive a solid-state akunja othamanga kwambiri (SSDs), kapena kuyembekezera kuthetsa zosowa za laputopu ndi kutumiza deta ndi chingwe chimodzi, Gen 2 ndi chisankho chabwino. Makamaka kwa ogwiritsa ntchito ma laputopu atsopano, aChingwe cha USB C 3.1 kupita ku USB Akapena adaputala yomwe imathandizira Gen 2 imatha kulumikiza bwino zida ku zida zachikhalidwe kapena ma hub okhala ndi ma interface ambiri a Type-A, pomwe ikuwonetsetsa kuti deta ikuyenda mwachangu.
Buku Lodziwitsa ndi Kugula
Chifukwa cha chisokonezo pa mayina a msika, chonde dziwani izi mukamagula:
Opanga ena amatha kulemba mayina awoUSB 3.1 Gen 1monga "USB 3.0"kapena" SuperSpeed USB"
USB 3.1 Gen 2ikhoza kutchedwa "SuperSpeed"USB 10 Gbps"
Miyezo yaposachedwa ya USB yasinthidwa dzina:USB 3.1 Gen 1tsopano yagawidwa m'magulu awiri "USB 3.2 Gen 1", ndipoUSB 3.1 Gen 2ndi tsopano "USB 3.2 Gen 2"
MukamagulaUSB C 3.1 kupita ku USB Aor Chingwe cha USB 3.1 A kupita ku Micro Bs, onetsetsani kuti kufotokozera kwa malonda kukuwonetsa momveka bwino ngati ikugwirizana ndi Gen 1 (5 Gbps) kapena Gen 2 (10 Gbps) kuti mupewe mavuto chifukwa cha chingwecho.
Kuti muwonetsetse kuti mwapeza magwiridwe antchito omwe mukufuna, yang'anani mosamala zomwe zafotokozedwa mu malonda m'malo mongodalira mawonekedwe a mawonekedwe okha. Ngati kuli kofunikira, onani zolemba zaukadaulo zovomerezeka.
Chidule
Kusankha pakati paUSB 3.1 Gen 1ndipo Gen 2 kwenikweni ikuphatikizapo kupeza mgwirizano pakati pa liwiro, mtengo, ndi zosowa zenizeni. Kaya ndi yatsopanoUSB C 3.1 kupita ku USB Ayankho losinthira kapena lachikaleUSB 3.1 A mpaka MICRO BNjira yolumikizira, Gen 1 imapereka yankho lodalirika komanso lotsika mtengo pa ntchito za tsiku ndi tsiku, pomwe Gen 2 imatsegula njira yachangu kwa ogwiritsa ntchito akatswiri komanso zochitika zapamwamba. Pamene kufunikira kwa liwiro lotumizira deta kuchokera kuzipangizo kukupitilira kukula, kumvetsetsa kusiyana kumeneku kudzakuthandizani kupanga zisankho zanzeru zaukadaulo pa moyo wanu wa digito.
Mtsogolomu, chifukwa cha kugwiritsa ntchito muyezo wa USB4, liwiro lotumizira deta lidzawonjezeka kufika pa 40 Gbps ndikuphatikiza protocol ya Thunderbolt 3. Koma mpaka nthawi imeneyo,USB 3.1 Gen 1ndipo Gen 2 idzakhalapo kwa nthawi yayitali, ikupereka zochitika zosiyanasiyana zogwiritsira ntchito ndi magulu ogwiritsa ntchito motsatana.
