Yintoni i-USB-C kwaye kutheni uza kuyifuna?
I-USB-C yeyona ndlela intsha yokutshaja nokudlulisa idatha. Okwangoku, ifakiwe kwizixhobo ezifana neelaptops, iifowuni, kunye neetablets zamva nje kwaye—ukuba ixesha lihambile—iya kusasazeka phantse kuyo yonke into esebenzisa isixhumi se-USB esidala nesinkulu ngoku.
I-USB-C inesimo esitsha nesincinci sokudibanisa esinokuguqulwa ukuze kube lula ukuyifaka. Iintambo ze-USB-C zinokuthwala amandla amaninzi, ngoko ke zinokusetyenziselwa ukutshaja izixhobo ezinkulu ezifana neelaptop. Zikwabonelela ngesantya sokudlulisa esiphindwe kabini kune-USB 3 kwi-10 Gbps. Nangona izihlanganisi zingahambelani ngasemva, imigangatho iyafana, ngoko ke iiadaptha zingasetyenziswa nezixhobo ezindala.
Nangona iinkcukacha ze-USB-C zapapashwa okokuqala ngo-2014, ngokwenene kukwiminyaka yokugqibela apho ubuchwepheshe bufikelele khona. Ngoku bujongeka njengotshintsho lokwenyani kungekuphela nje kwimigangatho emidala ye-USB, kodwa nakwezinye imigangatho efana neThunderbolt kunye neDisplayPort. Uvavanyo lusezandleni zokubonelela ngemigangatho emitsha yesandi se-USB kusetyenziswa i-USB-C njengendawo enokuthi ithathe indawo ye-jack yesandi ye-3.5mm. I-USB-C idibene ngokusondeleyo neminye imigangatho emitsha, njenge-USB 3.1 yesantya esikhawulezayo kunye nokuhanjiswa kwamandla e-USB ukuphucula ukuhanjiswa kwamandla kwiintambo ze-USB.
Uhlobo-C lunesimo esitsha sokudibanisa
I-USB Type-C inesixhumi esitsha nesincinci esibonakalayo—esilingana nesixhumi se-micro USB. Isixhumi se-USB-C ngokwaso sinokuxhasa imigangatho emitsha ye-USB enomdla efana ne-USB 3.1 kunye nokuhanjiswa kwamandla e-USB (i-USB PD).
Isixhumi se-USB esiqhelekileyo oqhelene naso yi-USB Type-A. Nangona sitshintshe ukusuka kwi-USB 1 ukuya kwi-USB 2 saza saya kwizixhobo ze-USB 3 zanamhlanje, eso sixhumi asitshintshanga. Sikhulu njengangaphambili, kwaye sixhuma ngendlela enye kuphela (ecacileyo ukuba asiyiyo indlela ozama ukuyixhuma ngayo okokuqala). Kodwa njengoko izixhobo zazisiba zincinci kwaye zincipha, ezo zikhumulo ze-USB ezinkulu azizange zilingane. Oku kwabangela ukuba kubekho ezinye iimilo ezininzi zesixhumi se-USB ezifana nezixhumi "ezincinci" kunye "nezincinci".
Olu qokelelo lungaqhelekanga lwezixhumi ezimile ngendlela eyahlukileyo zezixhobo ezinobukhulu obahlukeneyo ekugqibeleni luyaphela. I-USB Type-C inikezela ngomgangatho omtsha wesixhumi omncinci kakhulu. Ilingana nesinye kwisithathu sobukhulu beplagi endala ye-USB Type-A. Lo ngumgangatho omnye wesixhumi ekufuneka zonke izixhobo zikwazi ukuwusebenzisa. Uza kufuna intambo enye kuphela, nokuba uqhagamshela i-hard drive yangaphandle kwi-laptop yakho okanye utshaja i-smartphone yakho kwitshaja ye-USB. Eso sixhumi sinye sincinci ngokwaneleyo ukuba singene kwisixhobo esiphathwayo esincinci kakhulu, kodwa sinamandla ngokwaneleyo okudibanisa zonke izinto ozifunayo kwi-laptop yakho. Intambo ngokwayo inezixhumi ze-USB Type-C kuzo zombini iziphelo—zonke zisixhumi esinye.
I-USB-C inika izinto ezininzi onokuzithanda. Iyakwazi ukutshintshwa, ngoko ke akuyi kufuneka uphinde ujike isixhumi ubuncinane kathathu ujonge indlela echanekileyo. Yimilo enye yesixhumi se-USB ekufuneka zonke izixhobo ziyithathe, ngoko ke akuyi kufuneka ugcine iintambo ezininzi ze-USB ezahlukeneyo ezineemilo ezahlukeneyo zesixhumi kwizixhobo zakho ezahlukeneyo. Kwaye akuyi kubakho zipoti zikhulu ezithatha indawo engafunekiyo kwizixhobo ezincinci.
Iiports ze-USB Type-C zingaxhasa neeprotokholi ezahlukeneyo kusetyenziswa "iindlela ezizezinye," ezikuvumela ukuba ube neeadaptha ezinokukhupha i-HDMI, i-VGA, i-DisplayPort, okanye ezinye iintlobo zonxibelelwano ezivela kuloo port enye ye-USB. I-adaptha ye-Apple ye-USB-C Digital Multiport ngumzekelo omhle woku, inikezela ngeadaptha ekuvumela ukuba uqhagamshele i-HDMI, i-VGA, izihlanganisi ezinkulu ze-USB Type-A, kunye nesihlanganisi esincinci se-USB Type-C ngeport enye. Ingxubakaxaka ye-USB, i-HDMI, i-DisplayPort, i-VGA, kunye neeports zamandla kwiilaptops eziqhelekileyo zinokuhlengahlengiswa zibe yiport enye.
I-USB-C, i-USB PD, kunye nokuhanjiswa kwamandla
Inkcazelo ye-USB PD ikwadibene kakhulu ne-USB Type-C. Okwangoku, uqhagamshelo lwe-USB 2.0 lubonelela ngamandla afikelela kwi-2.5 watts—aneleyo ukutshaja ifowuni okanye ithebhulethi yakho, kodwa yiloo nto kanye. Inkcazelo ye-USB PD exhaswa yi-USB-C inyusa olu nikezelo lwamandla ukuya kwi-100 watts. Isebenza kwicala ngalinye, ngoko ke isixhobo sinokuthumela okanye sifumane amandla. Kwaye la mandla anokudluliselwa ngexesha elinye isixhobo sithumela idatha kulo lonke uqhagamshelo. Olu hlobo lonikezelo lwamandla lunokukuvumela nokuba utshaje ilaptop, edla ngokufuna ukuya kuthi ga kwi-60 watts.
I-USB-C isenokuthetha ukuphela kwazo zonke iintambo zokutshaja zelaptop, yonke into itshaja ngoqhagamshelo oluqhelekileyo lwe-USB. Ungatshaja nelaptop yakho kwenye yeepakethi zebhetri eziphathwayo ozitshaja ii-smartphones zakho kunye nezinye izixhobo eziphathwayo ukususela namhlanje. Ungayifaka ilaptop yakho kwisibonisi sangaphandle esiqhagamshelwe kwintambo yamandla, kwaye eso sibonisi sangaphandle siya kutshaja ilaptop yakho njengoko uyisebenzisa njengesibonisi sangaphandle - konke oku ngoqhagamshelo oluncinci lwe-USB Type-C.
Kukho into enye enokuba luncedo—ubuncinane okwangoku. Ukuba nje isixhobo okanye intambo ixhasa i-USB-C oko kuthetha ukuba ikwaxhasa i-USB PD. Ngoko ke, kuya kufuneka uqinisekise ukuba izixhobo kunye neentambo ozithengayo zixhasa zombini i-USB-C kunye ne-USB PD.
I-USB-C, i-USB 3.1, kunye namaxabiso okuDlulisela
I-USB 3.1 ngumgangatho omtsha we-USB. I-bandwidth yethiyori ye-USB 3 yi-5 Gbps, ngelixa i-USB 3.1 iyi-10 Gbps. Oko kuphindwe kabini kune-bandwidth—ngokukhawuleza njengesixhumi seThunderbolt sesizukulwana sokuqala.
Nangona kunjalo, i-USB Type-C ayifani ne-USB 3.1. I-USB Type-C sisimo nje sokudibanisa, kwaye ubuchwepheshe obusisiseko bunokuba yi-USB 2 okanye i-USB 3.0. Enyanisweni, ithebhulethi ye-N1 Android yeNokia isebenzisa isixhumi se-USB Type-C, kodwa ngaphantsi kwayo yonke yi-USB 2.0—kungekho ne-USB 3.0. Nangona kunjalo, ezi teknoloji zihlobene kakhulu. Xa uthenga izixhobo, kuya kufuneka nje uhlale ujonge iinkcukacha kwaye uqiniseke ukuba uthenga izixhobo (kunye neentambo) ezixhasa i-USB 3.1.
Ukuhambelana ngasemva
Isixhumi se-USB-C esibonakalayo asihambelani nokubuyela umva, kodwa umgangatho we-USB osisiseko uhambelana naso. Awunakuzidibanisa izixhobo ze-USB ezindala kwi-port yanamhlanje, encinci ye-USB-C, kwaye awunakuzidibanisa isixhumi se-USB-C kwi-port ye-USB endala, enkulu. Kodwa oko akuthethi ukuba kufuneka ulahle zonke izixhobo zakho ezindala. I-USB 3.1 isahambelana nokubuyela umva neenguqulelo ezindala ze-USB, ngoko ke udinga nje i-adapter ebonakalayo ene-connector ye-USB-C kwelinye icala kunye ne-port ye-USB enkulu, endala kwelinye icala. Emva koko ungazifaka izixhobo zakho ezindala ngqo kwi-port ye-USB Type-C.
Ngokwenyani, iikhompyutha ezininzi ziya kuba neeports ze-USB Type-C kunye neeports ze-USB Type-A ezinkulu kwixesha elizayo. Uya kukwazi ukutshintsha kancinci kancinci ukusuka kwizixhobo zakho ezindala, ufumane izixhobo ezintsha ezisebenzisa izihlanganisi ze-USB Type-C.
