Iyini i-USB-C futhi kungani uzoyifuna?
I-USB-C iyindinganiso evelayo yokushaja nokudlulisa idatha.Njengamanje, ifakiwe kumadivayisi afana namakhompyutha aphathekayo amasha sha, amafoni, namathebulethi futhi—isikhathi esinikiwe—izosabalala kuyo yonke into okwamanje esebenzisa isixhumi esidala, esikhulu se-USB.
I-USB-C inesimo esisha, esincane sesixhumi esibuyiseleka emuva ukuze kube lula ukusixhuma. Izintambo ze-USB-C zingathwala amandla engeziwe, ngakho zingasetshenziswa ukushaja amadivayisi amakhulu njengamakhompyutha aphathekayo.Baphinde banikele ngokuphindwe kabili isivinini sokudlulisa se-USB 3 ku-10 Gbps.Nakuba izixhumi zingahambelani emuva, amazinga anjalo, ngakho-ke ama-adaptha angasetshenziswa namadivayisi amadala.
Yize imininingwane ye-USB-C yashicilelwa okokuqala ngo-2014, ikulo nyaka odlule lapho ubuchwepheshe bubambe khona.Manje isibumba ukuze ibe ukumiselela kwangempela hhayi nje kuphela amazinga amadala e-USB, kodwa namanye amazinga afana ne-Thunderbolt ne-DisplayPort.Ukuhlola kusemisebenzini yokuletha izinga elisha lomsindo we-USB kusetshenziswa i-USB-C njengendawo engase ibe khona yejekhi yomsindo engu-3.5mm.I-USB-C isondelene kakhulu namanye amazinga amasha, futhi—njenge-USB 3.1 ngesivinini esisheshayo kanye nokulethwa kwamandla e-USB ukuze kuthuthukiswe ukulethwa kwamandla ngoxhumo lwe-USB.
I-Type-C Ifaka Umumo Omusha Wokuxhuma
I-USB Type-C inesixhumi esibonakalayo esisha, esincane—cishe esilingana nosayizi wesixhumi se-USB encane.Isixhumi se-USB-C ngokwaso singasekela izinga le-USB elisha elijabulisayo njenge-USB 3.1 kanye nokulethwa kwamandla kwe-USB (i-USB PD).
Isixhumi esijwayelekile se-USB osijwayele kakhulu i-USB Type-A.Ngisho nanjengoba sisuke ku-USB 1 saya ku-USB 2 saya kumadivayisi esimanje e-USB 3, leso sixhumi asishintshile.Kukhulu njengakuqala, futhi kuxhumeka ngendlela eyodwa kuphela (okusobala ukuthi akuyona indlela ozama ngayo ukuyixhuma okokuqala).Kepha njengoba amadivayisi aba mancane futhi aba mncane, lezo zimbobo ezinkulu ze-USB azizange zilingane.Lokhu kudale ezinye izinhlobo eziningi zezixhumi ze-USB njengezixhumi “ezincane” kanye “nezincane”.
Leli qoqo elingajwayelekile lezixhumi ezinomumo ohlukile wamadivayisi anosayizi ohlukile liyafika ekugcineni.I-USB Type-C inikeza izinga lokuxhuma elisha elincane kakhulu.Icishe ibe ingxenye yesithathu kasayizi wepulaki ye-USB Type-A endala.Lesi yizinga elilodwa lesixhumi okufanele zonke izisetshenziswa zikwazi ukulisebenzisa.Uzodinga nje ikhebula elilodwa, noma ngabe uxhuma i-hard drive yangaphandle kwikhompyutha yakho ephathekayo noma ushaja i-smartphone yakho eshaja ye-USB.Leso sixhumi esincane esincane ngokwanele ukuthi singangena kudivayisi yeselula ezacile kakhulu, kodwa futhi sinamandla ngokwanele ukuxhuma wonke ama-peripherals owafunayo kukhompyutha yakho ephathekayo.Ikhebuli ngokwayo inezixhumi ze-USB Type-C kuzo zombili iziphetho—sonke isixhumi esisodwa.
I-USB-C inikeza okuningi ongakuthanda.Iyabuyiseleka emuva, ngakho-ke ngeke kusadingeka uphenye isixhumi okungenani izikhathi ezintathu ukuze uthole umumo olungile.Kuwumumo owodwa wesixhumi se-USB okufanele wonke amadivaysi asebenzise, ngakho-ke ngeke kudingeke ukuthi ugcine inqwaba yamakhebuli e-USB ahlukene anomumo ohlukile wokuxhuma kumadivayisi akho ahlukahlukene.Futhi ngeke usaba namachweba amakhulu athatha inani elingadingekile legumbi kumadivayisi ahlala ezacile.
Izimbobo ze-USB Type-C zingase futhi zisekele izinqubo ezihlukahlukene ezihlukene zisebenzisa “amanye amamodi,” okukuvumela ukuthi ube nama-adaptha akwazi ukukhipha i-HDMI, i-VGA, i-DisplayPort, noma ezinye izinhlobo zokuxhuma kuleyo mbobo ye-USB eyodwa.I-USB-C Digital Multiport Adapter yakwa-Apple iyisibonelo esihle salokhu, inikezela nge-adaptha ekuvumela ukuthi uxhume i-HDMI, i-VGA, izixhumi ezinkulu ze-USB Type-A, nesixhumi esincane se-USB Type-C ngembobo eyodwa.Isiphithiphithi se-USB, i-HDMI, i-DisplayPort, i-VGA, nezimbobo zamandla kumakhompuyutha aphathekayo ajwayelekile zingahlelwa zibe uhlobo olulodwa lwembobo.
I-USB-C, i-USB PD, kanye Nokulethwa kwamandla
Ukucaciswa kwe-USB PD nakho kuxhumene eduze ne-USB Type-C.Okwamanje, uxhumano lwe-USB 2.0 lunikeza amandla afika kwangu-2.5—anele ukushaja ifoni noma ithebulethi yakho, kodwa lokho kumayelana nakho.Ukucaciswa kwe-USB PD okusekelwa yi-USB-C kwenyusa lokhu kulethwa kwamandla kuma-watts angu-100.Iqondiswa kabili, ngakho idivayisi ingathumela noma yamukele amandla.Futhi la mandla angadluliswa ngesikhathi esifanayo idivayisi idlulisela idatha kuyo yonke uxhumano.Lolu hlobo lokulethwa kwamandla lungakuvumela ngisho ukuthi ushaje ikhompuyutha ephathekayo, ngokuvamile edinga ama-watts angaba ngu-60.
I-USB-C ingapela isiphetho sazo zonke lezo zintambo zokushaja zekhompuyutha ephathekayo, nayo yonke into ishaja ngoxhumano lwe-USB olujwayelekile.Ungakwazi ngisho nokushaja ikhompuyutha ephathekayo yakho kusuka kwelinye lalawa maphakethe ebhethri aphathwayo owashaja ama-smartphones akho namanye amadivaysi aphathekayo kusukela namuhla.Ungakwazi ukuxhuma ikhompuyutha ephathekayo yakho kusibonisi sangaphandle esixhunywe kwikhebuli yamandla, futhi leso sibonisi sangaphandle sizoshaja ikhompuyutha ephathekayo yakho njengoba uyisebenzise njengesibonisi sangaphandle — konke ngokuxhumeka okukodwa okuncane kwe-USB Type-C.
Kukhona okukodwa okubanjiwe, noma kunjalo-okungenani okwamanje.Ngenxa yokuthi idivayisi noma ikhebula isekela i-USB-C kusho ukuthi nayo isekela i-USB PD.Ngakho-ke, uzodinga ukwenza isiqiniseko sokuthi amadivayisi namakhebuli owathengayo asekela i-USB-C ne-USB PD.
I-USB-C, i-USB 3.1, kanye namazinga okudlulisa
I-USB 3.1 iyizinga le-USB elisha.Umkhawulokudonsa wethiyori we-USB 3 ungu-5 Gbps, kuyilapho i-USB 3.1 ingu-10 Gbps.Lokho kuphinda kabili umkhawulokudonsa—ngokushesha njengesixhumi se-Thunderbolt sesizukulwane sokuqala.
I-USB Type-C ayiyona into efanayo ne-USB 3.1, noma kunjalo.I-USB Type-C iwumumo nje wokuxhuma, futhi ubuchwepheshe obungaphansi bungaba i-USB 2 noma i-USB 3.0.Eqinisweni, ithebhulethi ye-Android ye-N1 yakwaNokia isebenzisa isixhumi se-USB Type-C, kodwa ngaphansi kwayo yonke i-USB 2.0—hhayi ngisho ne-USB 3.0.Nokho, lobu buchwepheshe buhlobene eduze.Lapho uthenga amadivayisi, uzodinga nje ukubeka iso lakho emininingwaneni futhi uqiniseke ukuthi uthenga amadivayisi (nezintambo) ezisekela i-USB 3.1.
Ukuvumelana Kwasemuva
Isixhumi esibonakalayo se-USB-C asihambisani emuva, kodwa izinga le-USB eliyisisekelo liwukuthi.Awukwazi ukuxhuma amadivaysi e-USB amadala embobeni yesimanje, encane ye-USB-C, futhi awukwazi ukuxhuma isixhumi se-USB-C embotsheni ye-USB endala, enkulu.Kodwa lokho akusho ukuthi kufanele ulahle wonke ama-peripherals akho amadala.I-USB 3.1 isabuyela emuva-ihambisana nezinguqulo ezindala ze-USB, ngakho-ke udinga nje i-adaptha ephathekayo enesixhumanisi se-USB-C ngakolunye uhlangothi kanye nembobo ye-USB yesitayela esidala ngakolunye uhlangothi.Ungabese uxhuma amadivayisi akho amadala ngokuqondile embobeni yohlobo C ye-USB.
Eqinisweni, amakhompyutha amaningi azoba nazo zombili izimbobo ze-USB Type-C nezimbobo ezinkulu ze-USB Type-A esikhathini esizayo esiseduze.Uzokwazi ukuguquka kancane kancane ukusuka kumadivayisi akho amadala, uthole ama-peripheral amasha ngezixhumi ze-USB Type-C.
