Yiziphi izintambo eziphozithivu nezingezinhle ekhebula le-USB
Okuqukethwe
Ngaphakathi kwe-"universal serial bus" noma i-USB, kunezintambo ezine, ngokuvamile ezibomvu, eziluhlaza okotshani, ezimhlophe, nezimnyama. Ngayinye yalezi zintambo inesiginali ehambisanayo noma umsebenzi. Ukuhlonza amatheminali amahle kanye namabi kubalulekile lapho usebenza nawo.
Nakuba kunezintambo ezimbili ezinhle nezingezinhle sezizonke, ngayinye inomsebenzi ohlukile.
Kulesi sihloko, sizohlala kulezi zintambo ngokuningiliziwe.
Yenzani ngayinye kwezine izintambo zekhebula le-USB?
Enye yamachweba asetshenziswa kakhulu kanye nezivumelwano zokuxhumana kumadivayisi i-USB noma i-Universal Serial Bus. Inhloso ye-USB kwakuwukulawula izimbobo lapho izinsiza zekhompyutha ezifana namaphrinta namakhibhodi axhunywe kuzo. Ungathola izinketho zembobo kumagajethi afana nomakhalekhukhwini, izikena, amakhamera, nezilawuli zegeyimu ezixhumana nababungazi. (1)
Uma uvula ikhebula le-USB, ungabona imibala emine ehlukene yezintambo ze-USB: obomvu nomnyama ukuze uthole amandla, omhlophe nohlaza ngedatha, njalo njalo. Intambo ephozithivu ephethe ama-volts angu-5 ibomvu; ucingo olunegethivu, oluvame ukubizwa ngokuthi i-ground wire, lumnyama. Kukhona umdwebo we-pinout wohlobo ngalunye lokuxhuma nge-USB; lezi yizicucu zensimbi ezincane ngaphakathi kwesixhumi ezisetshenziselwa ukufinyelela ngayinye yalezi zintambo nemisebenzi yazo.
Imibala yekhebula le-USB nokuthi isho ukuthini
| Umbala wentambo | inkomba |
| Intambo ebomvu | Ikhebula lamandla elihle linikeza ama-volts angu-5 DC. |
| ucingo olumnyama | Intambo yamandla ephansi noma enegethivu. |
| Intambo emhlophe | Intambo yedatha eqondile. |
| Intambo eluhlaza | Intambo yedatha engalungile. |
Okunye ukucaciswa kombala wentambo ye-USB
Kwezinye izintambo ze-USB, ungathola inhlanganisela ehlukahlukene yemibala yocingo, okuhlanganisa owolintshi, oluhlaza okwesibhakabhaka, omhlophe, noluhlaza.
Incazelo yezintambo ezinhle noma ezimbi kulolu hlelo lombala ihlukile. Kulokhu, kufanele uhlole ithebula elingezansi:
| Umbala wentambo | inkomba |
| ucingo oluwolintshi | Ikhebula lamandla elihle linikeza amandla angu-5 volt DC. |
| Intambo emhlophe | Intambo yamandla ephansi noma enegethivu. |
| ucingo oluluhlaza | Intambo yedatha engalungile. |
| Intambo eluhlaza | Intambo yedatha eqondile. |
Izinhlobo zezintambo ze-USB
Kunezinhlobo ezahlukahlukene ze-USB, futhi umthetho olandelwayo wekhebula le-USB unquma ukuthi ingadlulisa ngokushesha kangakanani idatha. Isibonelo, imbobo ye-USB 2.0 ingadlulisela idatha kufika ku-480 Mbps, kuyilapho imbobo ye-USB 3.1 Gen 2 ingadlulisela idatha ku-10 Mbps. Ungasebenzisa ithebula elingezansi ukuze uqonde isivinini nezici zohlobo ngalunye lwe-USB:
| Uhlobo lwe-USB | Iyakwazi ukudlala amavidiyo? | Ingabe inganikeza amandla? | Isilinganiso se-Baud |
| USB 1.1 | No | No | 12 Mbps. |
| USB 2.0 | No | Yebo | 480 Mbps. |
| USB 3.0 | Yebo | Yebo | 5 Гбит / p |
| USB 3.1 | Yebo | Yebo | 10 Гбит / p |
Imibuzo evame ukubuzwa
Yini eyenza i-USB-C ihluke ku-USB evamile?
Uma kuqhathaniswa ne-USB-A, ekwazi kuphela ukuphatha kufika ku-2.5W kanye ne-5V, i-USB-C manje isingakwazi ukuphatha kahle u-100W kanye no-20V kumadivayisi amakhulu. Ukushaja ngokudlula - ngokuyisisekelo ihabhu le-USB elinika amandla amakhompyutha aphathekayo futhi lishaje amanye amadivayisi ngesikhathi esifanayo - ingenye yalezo zinzuzo eziwusizo.
Ingabe imigqa eluhlaza nemhlophe inendaba?
Izintambo ezithi positive-negative yizintambo ezibaluleke kakhulu. Ukwazi ukuthi lezi zisekhethi zikagesi zinemibala enjani kubalulekile njengoba zibalulekile ukuze unike amandla okokusebenza kwakho.
Ingabe ikhebula le-USB lingahlukaniswa futhi lixhunywe?
Ungazenzela ezakho izintambo ze-USB ngokusika nokuhlanganisa izintambo ezikhona zibe ubude nohlobo lwesixhumi olufunayo. Okuwukuphela kwamathuluzi adingekayo kule nqubo ama-wire cutter kanye ne-tape kagesi, nakuba i-solder iron ne-heat shrink tubing ingasetshenziswa ukuthuthukisa ikhwalithi yekhebula. (2)
Bheka ezinye zezihloko zethu ngezansi.
- Indlela yokuhlukanisa ucingo olunegethivu koluphozithivu
- intambo emhlophe iphozithivu noma inegethivu
- Iyini intambo eluhlaza okwesibhakabhaka kufeni yesilingi
