Iyini i-USB-C futhi kungani uzoyifuna?
I-USB-C iyindinganiso entsha yokushaja nokudlulisa idatha. Njengamanje, ifakiwe kumadivayisi afana nama-laptop amasha, amafoni, namathebulethi futhi—uma isikhathi sinikezwa—izosakazeka cishe kuyo yonke into esebenzisa isixhumi se-USB esidala nesikhudlwana.
I-USB-C inesimo esisha nesincane sokuxhuma esikwazi ukuguqulwa ukuze kube lula ukusixhuma. Izintambo ze-USB-C zingathwala amandla amaningi kakhulu, ngakho zingasetshenziswa ukushaja amadivayisi amakhulu njengama-laptop. Ziphinde zinikeze isivinini sokudlulisa esiphindwe kabili kune-USB 3 ku-10 Gbps. Nakuba izixhumi zingahambisani nokubuyela emuva, izindinganiso ziyasebenza, ngakho-ke ama-adapter angasetshenziswa namadivayisi amadala.
Nakuba imininingwane ye-USB-C yanyatheliswa okokuqala ngo-2014, empeleni kusesenyakeni wokugcina lapho ubuchwepheshe buqale khona. Manje sebuqala ukuba yindawo yangempela hhayi nje kuphela yezindinganiso ze-USB ezindala, kodwa nezinye izindinganiso ezifana ne-Thunderbolt ne-DisplayPort. Ukuhlola kusesemsebenzini wokuletha indinganiso entsha yomsindo we-USB kusetshenziswa i-USB-C njengendlela engaba khona yokufaka esikhundleni se-jack yomsindo engu-3.5mm. I-USB-C ixhumene kakhulu nezinye izindinganiso ezintsha, futhi—njenge-USB 3.1 yesivinini esisheshayo kanye nokulethwa kwamandla e-USB ukuze kuthuthukiswe ukulethwa kwamandla phezu kokuxhumeka kwe-USB.
Uhlobo-C lunesimo esisha sesixhumi
I-USB Type-C inesixhumi esisha esincane esibonakalayo—cishe esilingana nesixhumi se-micro USB. Isixhumi se-USB-C ngokwaso singasekela amazinga amasha e-USB ajabulisayo njenge-USB 3.1 kanye nokulethwa kwamandla e-USB (i-USB PD).
Isixhumi se-USB esijwayelekile osijwayele kakhulu yi-USB Type-A. Ngisho noma sesishintshe kusuka ku-USB 1 saya ku-USB 2 saya kumadivayisi e-USB 3 esimanje, leso sixhumi sihlale sinjalo. Sikhulu njengakuqala, futhi sixhuma ngendlela eyodwa kuphela (okusobala ukuthi akuyona indlela ozama ukuyixhuma ngayo okokuqala). Kodwa njengoba amadivayisi eba mancane futhi encipha, lawo machweba e-USB amakhulu awazange afane. Lokhu kwabangela ezinye izimo eziningi zesixhumi se-USB njengezixhumi “ezincane” kanye “nezincane”.
Leli qoqo elixakile lezixhumi ezinesimo esihlukile zamadivayisi anosayizi ohlukene selizophela ekugcineni. I-USB Type-C inikeza indinganiso entsha yesixhumi encane kakhulu. Icishe ibe yingxenye yesithathu yosayizi wepulaki endala ye-USB Type-A. Lena indinganiso eyodwa yesixhumi okufanele wonke amadivayisi akwazi ukuyisebenzisa. Uzodinga ikhebula elilodwa nje, kungakhathaliseki ukuthi uxhuma i-hard drive yangaphandle kwi-laptop yakho noma ushaja i-smartphone yakho kusuka kushaja ye-USB. Leso sixhumi esincane sincane ngokwanele ukungena kudivayisi yeselula encane kakhulu, kodwa futhi sinamandla okuxhuma zonke izinto ozifunayo kwi-laptop yakho. Ikhebula ngokwalo linezixhumi ze-USB Type-C kuzo zombili izinhlangothi—konke kuyisixhumi esisodwa.
I-USB-C inikeza okuningi ongakuthanda. Iyakwazi ukuguqulwa, ngakho-ke ngeke kusadingeka ukuthi uphendule isixhumi okungenani kathathu ufuna ukuma okufanele. Kuyisimo esisodwa sesixhumi se-USB okufanele wonke amadivayisi asisebenzise, ngakho ngeke kudingeke ugcine izintambo eziningi ze-USB ezihlukene ezinezimo ezahlukene zesixhumi kumadivayisi akho ahlukahlukene. Futhi ngeke ube namachweba amakhulu athatha isikhala esingadingekile kumadivayisi amancane kakhulu.
Amachweba e-USB Type-C angasekela nezinhlobo ezahlukene zephrothokholi kusetshenziswa "amamodi ahlukile," okuvumela ukuthi ube nama-adaptha angakhipha i-HDMI, i-VGA, i-DisplayPort, noma ezinye izinhlobo zokuxhumeka kusuka kuleyo port eyodwa ye-USB. I-adaptha ye-USB-C Digital Multiport ye-Apple iyisibonelo esihle salokhu, inikeza i-adaptha ekuvumela ukuthi uxhume i-HDMI, i-VGA, izixhumi ezinkulu ze-USB Type-A, kanye nesixhumi esincane se-USB Type-C nge-port eyodwa. Ukudideka kwamachweba e-USB, i-HDMI, i-DisplayPort, i-VGA, kanye namandla kuma-laptop ajwayelekile kungahlelwa kube uhlobo olulodwa lwe-port.
I-USB-C, i-USB PD, kanye nokulethwa kwamandla
Incazelo ye-USB PD nayo ixhumene kakhulu ne-USB Type-C. Njengamanje, uxhumano lwe-USB 2.0 lunikeza amandla afinyelela ku-2.5 watts—anele ukushaja ifoni noma ithebhulethi yakho, kodwa yilokho kuphela. Incazelo ye-USB PD esekelwa yi-USB-C ikhuphula lokhu kulethwa kwamandla kube ama-watts ayi-100. Iqondisa kabili, ngakho idivayisi ingathumela noma yamukele amandla. Futhi la mandla angadluliselwa ngesikhathi esifanayo idivayisi idlulisela idatha kuyo yonke inethiwekhi. Lolu hlobo lokulethwa kwamandla lungakuvumela ngisho nokushaja i-laptop, evame ukudinga ama-watts angaba ngu-60.
I-USB-C ingasho ukuphela kwazo zonke lezo zintambo zokushaja ze-laptop ezizimele, konke kushaja ngoxhumano olujwayelekile lwe-USB. Ungashaja ngisho ne-laptop yakho kusuka kwenye yalezo zikhwama zebhethri eziphathwayo oshaja ngazo ama-smartphone akho namanye amadivayisi aphathekayo kusukela namuhla. Ungaxhuma i-laptop yakho kusibonisi sangaphandle esixhunywe kukhebula lamandla, futhi leso sibonisi sangaphandle sizoshaja i-laptop yakho njengoba uyisebenzisa njengesibonisi sangaphandle - konke ngoxhumano olulodwa oluncane lwe-USB Type-C.
Nokho, kukhona into eyodwa ebambekayo—okungenani okwamanje. Ukuthi nje idivayisi noma ikhebula lisekela i-USB-C kusho ukuthi lisekela ne-USB PD. Ngakho-ke, kuzodingeka uqiniseke ukuthi amadivayisi nezintambo ozithengayo zisekela i-USB-C kanye ne-USB PD.
I-USB-C, i-USB 3.1, kanye namanani okudlulisa
I-USB 3.1 iyindinganiso entsha ye-USB. I-bandwidth ye-USB 3 engokwengqondo ingu-5 Gbps, kanti i-USB 3.1 ingu-10 Gbps. Lokho kuphindwe kabili kune-bandwidth—ngokushesha njengesixhumi se-Thunderbolt sesizukulwane sokuqala.
I-USB Type-C ayifani ne-USB 3.1, noma kunjalo. I-USB Type-C imane nje iyisimo sesixhumi, futhi ubuchwepheshe obuyisisekelo bungaba yi-USB 2 noma i-USB 3.0. Eqinisweni, ithebhulethi ye-Android ye-Nokia N1 isebenzisa isixhumi se-USB Type-C, kodwa ngaphansi kwayo yonke yi-USB 2.0—ngisho ne-USB 3.0. Kodwa-ke, lobu buchwepheshe buhlobene kakhulu. Uma uthenga amadivayisi, kuzodingeka nje uqaphele imininingwane futhi uqiniseke ukuthi uthenga amadivayisi (nezintambo) ezisekela i-USB 3.1.
Ukuhambisana Kokubuyela Emuva
Isixhumi se-USB-C esingokoqobo asihambisani nokubuyela emuva, kodwa indinganiso ye-USB eyisisekelo iyahambisana. Awukwazi ukuxhuma amadivayisi e-USB amadala echwebeni le-USB-C elincane, futhi awukwazi ukuxhuma isixhumi se-USB-C echwebeni le-USB elidala nelikhulu. Kodwa lokho akusho ukuthi kufanele ulahle zonke izinto zakho ezisetshenziswayo ezindala. I-USB 3.1 isahambisana nokubuyela emuva nezinguqulo ezindala ze-USB, ngakho-ke udinga nje i-adaptha engokoqobo enesixhumi se-USB-C kolunye uhlangothi kanye nesixhumi se-USB esikhulu, esidala kolunye uhlangothi. Ungabe usuxhuma amadivayisi akho amadala ngqo echwebeni le-USB Type-C.
Eqinisweni, amakhompyutha amaningi azoba nama-port e-USB Type-C kanye nama-port e-USB Type-A amakhulu esikhathini esizayo esiseduze. Uzokwazi ukushintsha kancane kancane kusuka kumadivayisi akho amadala, uthole izinto ezintsha ezihambisana nezixhumi ze-USB Type-C.
