He aha nā uea maikaʻi a maikaʻi ʻole i ke kelepona USB
Nā mea
I loko o ka "universal serial bus" a i ʻole USB, ʻehā mau uea, ʻo ia ka ʻulaʻula, ʻōmaʻomaʻo, keʻokeʻo, a me ka ʻeleʻele. Loaʻa i kēlā me kēia uea kahi hōʻailona a i ʻole hana. He mea koʻikoʻi ka ʻike ʻana i nā hopena maikaʻi a maikaʻi ʻole ke hana pū me lākou.
ʻOiai ʻelua mau uea maikaʻi a me nā uea maikaʻi ʻole i ka huina, ʻokoʻa ka hana o kēlā me kēia.
Ma kēia ʻatikala, e kamaʻilio mākou e pili ana i kēia mau uea i nā kikoʻī hou aku.
He aha ka hana o kēlā me kēia o nā uea ʻehā o ke kelepona USB?
ʻO kekahi o nā awa i hoʻohana nui ʻia a me nā protocol kamaʻilio ma nā polokalamu ʻo USB a i ʻole Universal Serial Bus. ʻO ke kumu o ka USB ʻo ia ka hoʻoponopono ʻana i nā awa i hoʻopili ʻia ai nā lako kamepiula e like me nā mea paʻi a me nā kī. Hiki iā ʻoe ke loaʻa i nā koho awa ma nā hāmeʻa e like me nā kelepona paʻalima, nā mīkini paʻi kiʻi, nā kāmela, a me nā mea hoʻokele pāʻani e kamaʻilio pū me nā pūʻali koa. (1)
Ke wehe ʻoe i ke kelepona USB, hiki iā ʻoe ke ʻike i ʻehā mau kala like ʻole o nā uea USB: ʻulaʻula a ʻeleʻele no ka mana, keʻokeʻo a me ka ʻōmaʻomaʻo no ka ʻikepili, a pēlā aku. ʻO ka uea maikaʻi e lawe ana i 5 volts he ʻulaʻula; ʻo ka uea maikaʻi ʻole, i kapa pinepine ʻia ʻo ka uea honua, he ʻeleʻele. Aia kahi diagram pinout no kēlā me kēia ʻano pili USB; ʻo ia nā ʻāpana metala liʻiliʻi i loko o ka mea hoʻohui i hoʻohana ʻia e komo i kēlā me kēia o kēia mau kaula a me kā lākou mau hana.
Nā kala uwea USB a me ke ʻano o ia mau mea
| Waihona uea | hōʻailona |
| Uea ʻulaʻula | Hāʻawi ke kaula mana maikaʻi i 5 volts DC. |
| Uea ʻeleʻele | Uea mana honua a ʻino paha. |
| Uea keʻokeʻo | Uaea ʻikepili maikaʻi. |
| Uea ʻōmaʻomaʻo | Uaea ʻikepili ʻino. |
ʻO nā kikoʻī kala uea USB ʻē aʻe
Ma kekahi mau kaula USB, hiki iā ʻoe ke loaʻa nā hui like ʻole o nā kala uea, me ka ʻalani, uliuli, keʻokeʻo, a me ka ʻōmaʻomaʻo.
ʻOkoʻa ka wehewehe ʻana o nā uwea maikaʻi a maikaʻi ʻole paha i kēia ʻano kala. I kēia hihia, pono ʻoe e nānā i ka papa ma lalo:
| Waihona uea | hōʻailona |
| Uea ʻalani | Hāʻawi ke kaula mana maikaʻi i ka mana 5 volt DC. |
| Uea keʻokeʻo | Uea mana honua a ʻino paha. |
| uwea uliuli | Uaea ʻikepili ʻino. |
| Uea ʻōmaʻomaʻo | Uaea ʻikepili maikaʻi. |
Nā ʻano o nā kaula USB
Aia nā ʻano USB like ʻole, a ʻo ka protocol o ke kelepona USB e hoʻoholo i ka wikiwiki o ka hiki ke hoʻololi i ka ʻikepili. No ka laʻana, hiki i kahi port USB 2.0 ke hoʻololi i ka ʻikepili a hiki i 480 Mbps, ʻoiai hiki i kahi port USB 3.1 Gen 2 ke hoʻololi i ka ʻikepili ma 10 Mbps. Hiki iā ʻoe ke hoʻohana i ka papa ma lalo nei e hoʻomaopopo i ka wikiwiki a me nā hiʻohiʻona o kēlā me kēia ʻano USB:
| ʻAno USB | Hiki iā ia ke pāʻani wikiō? | Hiki iā ia ke hāʻawi i ka mana? | Ka helu helu Baud |
| USB 1.1 | No | No | 12 Mbps. |
| USB 2.0 | No | ia | 480 Mbps. |
| USB 3.0 | ia | ia | 5 Gbps |
| USB 3.1 | ia | ia | 10 Gbps |
Nīnau pinepineʻia
He aha ka ʻokoʻa o USB-C mai ka USB maʻamau?
Hoʻohālikelike ʻia me USB-A, hiki iā ia ke hoʻopaʻa i ka 2.5W a me 5V wale nō, hiki i ka USB-C ke hoʻohana ʻoluʻolu i ka 100W a me 20V no nā polokalamu ʻoi aku ka nui. ʻO ka hoʻopiʻi hele ʻana - ma ke ʻano he USB hub e hoʻohana ana i nā kamepiula a hoʻopiʻi i nā polokalamu ʻē aʻe i ka manawa like - ʻo ia kekahi o kēlā mau mea pono.
He mea nui anei nā laina ʻōmaʻomaʻo a keʻokeʻo?
ʻO nā uwea maikaʻi-ʻole ka mea nui loa. He mea koʻikoʻi ka ʻike ʻana i ka waihoʻoluʻu o kēia mau kaapuni uila no ka mea he mea nui ia i ka mana o kāu mau mea hana.
Hiki ke hoʻokaʻawale ʻia ke kelepona USB?
Hiki iā ʻoe ke hana i kāu mau uwea USB ponoʻī ma ka ʻoki ʻana a me ka hoʻopili ʻana i nā kaula i loaʻa i ka lōʻihi a me ke ʻano hoʻohui āu e makemake ai. ʻO nā mea hana wale nō e pono ai no kēia kaʻina hana, ʻo ia nā mea ʻoki uwea a me ka lipine uila, ʻoiai hiki ke hoʻohana ʻia ka hao hao a me ka wela wela e hoʻomaikaʻi i ka maikaʻi o ke kaula.

E nānā i kekahi o kā mākou ʻatikala ma lalo nei.
- Pehea e hoʻokaʻawale ai i kahi uea maikaʻi ʻole mai kahi uea maikaʻi
- uwea keʻokeʻo maikaʻi a maikaʻi ʻole
- He aha ka uwea polū ma ka peʻahi kaupaku
