Waa maxay faraqa u dhexeeyaUSB 3.1 Gen 1iyoBilowgii 2aad?
USB 3.1 Gen 1iyoBilowgii 2aad: Soo bandhigida Farqiga Muhiimka ah ee u dhexeeya Labada Heer
Marka aad wax ka iibsanayso aaladaha kaydinta dibadda, saldhigyada dekedda, ama laptop-yada, noocyada isku-xirka USB-ga badanaa way wareeri karaan, gaar ahaan marka ereyada sidaUSB 3.1 Gen 1iyoBilowgii 2aadhad iyo jeer way soo baxaan. In kasta oo labaduba ay ka tirsan yihiinUSB 3.1Qoyska caadiga ah, waxaa jira farqi weyn oo ku saabsan waxqabadka iyo codsiyada wax ku oolka ah. Maqaalkani wuxuu si qoto dheer u eegi doonaa kala duwanaanshaha muhiimka ah ee u dhexeeya labada qeexitaan si uu kaaga caawiyo inaad sameyso doorasho xog ogaal ah.
Farqiga Xawaaraha: Kala Soocida Muhiimka ah
Xawaaraha ugu badan ee gudbinta aragtiyeed eeUSB 3.1 Gen 1(asal ahaan loo yaqaanayUSB 3.0) waa ilaa 5 Gbps (qiyaastii 625 MB/s). Xawaarahani wuxuu ku filan yahay isticmaalka maalinlaha ah, sida isku xirka jiirka, kiiboodhka, daabacayaasha, ama wareejinta faylasha yaryar sida dukumentiyada iyo muusikada.
USB 3.1 Gen 2, dhanka kale, waxay labanlaabaysaa xadkan sare ilaa10 Gbps(qiyaastii 1250 MB/s). Taas macnaheedu waa marka la wareejinayo faylasha waaweyn, sida fiidiyowyada 4K, sawirrada qaabka RAW, ama xirmooyinka rakibidda ciyaaraha waaweyn, waqtiga loo baahan yahay si weyn ayaa loo dhimi doonaa. Tusaale ahaan, wareejinta faylka filimka 50GB 4K, Gen 2 wuxuu aragti ahaan badbaadin karaa ku dhawaad kala bar waqtiga marka la barbar dhigo Gen 1.
Aasaaska Farsamada iyo Qorshayaasha Codaynta
Farqiga xawaaraha wuxuu ku jiraa hufnaanta nidaamyada codeynta.USB 3.1 Gen 1Wuxuu adeegsadaa nidaamka codeynta 8b/10b, taasoo la micno ah in 8 ka mid ah 10-kii bits ee la gudbiyo oo keliya ay yihiin xog dhab ah, iyadoo hufnaantoodu ay tahay qiyaastii 80%. Sidaa darteed, baaxadda dhabta ah ee waxtarka leh ee heerka cayriin ee 5 Gbps waa qiyaastii 4 Gbps.
USB 3.1 Gen 2casriyeyn loogu sameeyay qaab-dhismeedka codeynta 128b/132b oo hufan, taasoo kordhinaysa hufnaanta ilaa qiyaastii 97%, taasoo u oggolaanaysa heerka cayriin ee 10 Gbps inuu bixiyo bandwidth wax ku ool ah oo ku dhawaad xawaare buuxa. Horumarkani ma aha oo kaliya inuu kordhiyo xawaaraha laakiin sidoo kale wuxuu yareeyaa dib u dhaca gudbinta.
Is-dhexgalka Jireed iyo Is-waafajinta
Waa muhiim in la ogaado in labadaUSB 3.1 Gen 1iyoBilowgii 2aadwaxay isticmaali karaan noocyada isku-xirka jireed ee la midka ah, oo ay ku jiraan:
Nooca-A (is-dhexgalka caadiga ah ee leydi)
Nooca-B (badanaa loo isticmaalo daabacayaasha iyo aaladaha kale)
Nooca-C (is-dhexgalka qaab-dhismeedka qaab-dhismeedka leh)
USB 3.1 A ilaa Micro B(badanaa loo isticmaalo darawallada adag ee dibadda iyo aaladaha Android ee duugga ah)
Waxaa si gaar ah muhiim u ah in la ogaado inNooca USB-Cwaa qaab is-dhexgal ah, ee maaha heer xawaare. Is-dhexgalka Nooca-C ayaa taageeri karaUSB 3.1 Gen 1, Gen 2, ama xitaa borotokoolka Thunderbolt 3. Sidaa darteed, xawaaraha gudbinta laguma go'aamin karo oo keliya qaabka is-dhexgalka. Tusaale ahaan, aUSB C ilaa USB AFiilada waxaa laga yaabaa inay leedahay xawaare dhab ah oo xaddidan heerarka isku-xirka labada dhinac iyo tayada fiilada, taas oo noqon karta 5 Gbps ee Gen 1 ama 10 Gbps ee Gen 2.
Awoodda Soo Saarista Korontada
Marka laga hadlayo korontada, hoos yimaadaUSB 3.1 Gen 1Caadiyan, is-dhexgalka wuxuu bixin karaa ugu badnaan 4.5W (5V/0.9A) oo awood ah. Is-dhexgalka Gen 2, marka loo isticmaalo hab-raaca Bixinta Awoodda USB (PD), wuxuu taageeri karaa ilaa 100W (20V/5A) oo koronto ah, taas oo ku filan inay dallacdo inta badan laptop-yada iyo inay ku shaqeyso qalabka waxqabadka sare leh. Waa in la ogaadaa marka la isticmaalayoFiilada USB 3.1 A ilaa Micro Bsi loogu xiro aaladaha, awoodda korontada waxaa badanaa xaddidaya qeexitaanka dekedda Micro B, korontaduna guud ahaan way hooseysaa.
Talo soo jeedin ku saabsan Codsiga Wax ku oolka ah
DooroUSB 3.1 Gen 1: Waxay ku habboon tahay isku xirka qalabka guud (kiiboodhka, jiirka, daabacayaasha), wareejinta dukumentiyada maalinlaha ah, ama sida is-dhexgalka dallacaadda taleefanka gacanta. Isticmaalayaasha miisaaniyad xaddidan ama baahida yar, aaladaha ku salaysan Gen 1 waxay bixiyaan qiimo wanaagsan oo lacag ah. Tusaale ahaan, qalabaynta hard drive-ka mobilada ee duugga ah oo leh heer caadi ahFiilada USB 3.1 A ilaa Micro B, xawaaraha Gen 1 badanaa waa ku filan yahay.
DooroUSB 3.1 Gen 2Haddii aad si joogto ah ugu baahan tahay inaad wareejiso faylasha waaweyn (sida tafatirka fiidiyowga, horumarinta ciyaaraha), ku xidh darawallada adag ee dibadda ee xawaaraha sare leh (SSDs), ama aad rajeyneyso inaad xalliso baahiyaha dallacaadda laptop-ka iyo gudbinta xogta hal fiilo, Gen 2 waa doorasho ka wanaagsan. Gaar ahaan dadka isticmaala laptop-yada cusub, aFiilada USB C 3.1 ilaa USB Aama adapter-ka taageera Gen 2 wuxuu si hufan ugu xidhi karaa aaladaha qalabka dhaqameed ama xarumaha leh tiro badan oo ah is-dhexgalka Nooca-A, iyadoo la hubinayo gudbinta xogta xawaaraha sare leh.
Tilmaamaha Aqoonsiga iyo Iibsiga
Jahwareerka ku jira magacyada suuqa awgeed, fadlan ogow waxyaabaha soo socda markaad wax iibsaneyso:
Soosaarayaasha qaar ayaa calaamadayn karaUSB 3.1 Gen 1sida "USB 3.0"ama" SuperSpeed USB"
USB 3.1 Gen 2waxaa loogu yeeri karaa "SuperSpeed"USB 10 Gbps"
Heerarka ugu dambeeyay ee USB-ga ayaa dib loo bixiyay:USB 3.1 Gen 1hadda waxaa loo kala saaraa "USB 3.2 Gen 1", iyoUSB 3.1 Gen 2hadda waa "USB 3.2 Gen 2"
Marka aad wax iibsanaysoUSB C 3.1 ilaa USB Aor Fiilada USB 3.1 A ilaa Micro Bs, hubi in sharraxaadda badeecaddu si cad u muujinayso inay taageerto Gen 1 (5 Gbps) ama Gen 2 (10 Gbps) si looga fogaado caqabadaha waxqabadka ee ka dhasha fiilada.
Si aad u hubiso inaad hesho waxqabadka la rabo, si taxaddar leh u hubi tilmaamaha badeecada halkii aad ku tiirsanaan lahayd oo keliya qaabka is-dhexgalka. Haddii loo baahdo, tixraac dukumentiyada farsamada rasmiga ah.
Soo Koobid
Doorashada u dhaxaysaUSB 3.1 Gen 1iyo Gen 2 asal ahaan waxay ku lug leedahay helitaanka dheelitirka u dhexeeya xawaaraha, qiimaha, iyo baahiyaha dhabta ah. Hadday tahay tan cusub.USB C 3.1 ilaa USB Axalka beddelka ama kan caadiga ahUSB 3.1 A ilaa MICRO BHabka isku xirka, Gen 1 wuxuu bixiyaa xal la isku halleyn karo oo kharash-ool ah oo loogu talagalay codsiyada maalinlaha ah, halka Gen 2 uu u furayo waddo degdeg ah dadka isticmaala xirfadlayaasha ah iyo xaaladaha waxqabadka sare leh. Maadaama baahida loo qabo xawaaraha gudbinta xogta ee aaladaha ay sii kordheyso, fahamka kala duwanaanshahan ayaa kaa caawin doona inaad sameyso go'aanno tignoolajiyadeed oo caqli badan noloshaada dijitaalka ah.
Mustaqbalka, iyadoo si ballaaran loo qaadanayo heerka USB4, xawaaraha gudbinta xogta ayaa sii kordhi doona ilaa 40 Gbps wuxuuna isku dari doonaa borotokoolka Thunderbolt 3. Laakiin ilaa markaas,USB 3.1 Gen 1iyo Gen 2 waxay wada noolaan doonaan muddo dheer, iyagoo u adeegaya xaalado codsi oo kala duwan iyo kooxaha isticmaalaha siday u kala horreeyaan.
