He aha nā ʻokoʻa ma waena o nā awa serial a me nā awa like?
I kēia lā e kamaʻilio mākou e pili ana i ka ʻokoʻa ma waena o ka port serial a me ka port parallel. ʻO nā port serial a me nā port parallel he mau kikowaena kamepiula maʻamau, i hoʻohana ʻia no ka hoʻopili ʻana i nā polokalamu a me nā kamepiula, akā nui nā ʻokoʻa ma waena o lākou.
Papa helu
1. He aha ke awa like?
ʻO ke awa Parallel ka pōkole o ka interface parallel. Hoʻohana ke awa like ʻole o nā kamepiula ʻenehana i kahi mea hoʻohui D-like 25-pin. ʻO ka mea i kapa ʻia ʻo "parallel" ʻo ia ka 8 bit o ka ʻikepili i hoʻouna ʻia i ka manawa like ma o nā laina like, no laila e hoʻomaikaʻi maikaʻi ʻia ka wikiwiki o ka lawe ʻana i ka ʻikepili, akā ua kaupalena ʻia ka lōʻihi o ka laina o ka hoʻoili like. Ma muli o ka piʻi ʻana o ka lōʻihi, e hoʻonui ʻia ka interference, a hiki i ka ʻikepili ke kuhi hewa. I kēia manawa, hoʻohana nui ʻia ka interface parallel ma ke ʻano he awa paʻi, etc.
2. He aha ke awa serial?
Ua kapa ʻia kekahi port serial he interface communication serial, a i ʻole port COM. E like me nā kūlana uila a me nā protocols, aia nā awa serial RS-232-C, RS-422, RS485, USB, etc.
3. He aha ka ʻokoʻa ma waena o lāua?
1. Hoʻohana nā awa Serial a me nā awa like nā ʻano hana like ʻole e hoʻouna i ka ʻikepili. ʻO ka port serial he interface hoʻouna bit-by-bit e hoʻouna ana i ka ʻikepili i ke kamepiula a i ʻole nā mea hana ʻē aʻe. Hiki i kēia ala ke hōʻoia i ka hilinaʻi o ka lawe ʻana i ka ʻikepili, akā lohi ka wikiwiki o ka lawe ʻana. ʻO ka port parallel he interface hoʻoili like ʻole e hiki ke hoʻouna i nā ʻāpana he nui o ka ʻikepili i ka manawa like, no laila ʻoi aku ka wikiwiki o ka hoʻouna ʻana, akā hiki ke hoʻopili ʻia e ka hoʻopili.
2. ʻO nā awa Serial a me nā awa like pū kekahi ʻokoʻa i nā mea hana a me nā hiʻohiʻona i hoʻohana ʻia. Hoʻohana mau ʻia nā awa Serial no ka hoʻopili ʻana i kekahi mau mea uila haʻahaʻa, e like me nā mea paʻi, modem, a me nā mea ʻē aʻe. Hoʻohana mau ʻia nā awa parallel no ka hoʻopili ʻana i nā hāmeʻa kiʻekiʻe, e like me ka hard drive, optical drive, a me nā mea ʻē aʻe, e koi ana i ka wikiwiki o ka hoʻouna ʻana a me ka nui o ka lawe ʻana i ka ʻikepili, akā loaʻa nā koi haʻahaʻa no ka hilinaʻi o ka lawe ʻana i ka ʻikepili.
3. Ka pili kino ʻokoʻa pū kekahi o nā awa serial a me nā awa like. Hoʻohana maʻamau nā awa Serial i nā pilina DB9 a i ʻole DB25, aʻo nā awa like ʻole e hoʻohana i nā interface DB25 a i ʻole nā pine port parallel. Eia kekahi, hiki i nā awa serial ke hoʻohana i nā interface USB no ka lawe ʻana i ka ʻikepili.
4. Ka hopena
Nui nā ʻokoʻa ma waena o nā awa serial a me nā awa like ʻole e pili ana i nā ʻano hoʻoili ʻikepili, nā hiʻohiʻona hoʻohana, a me nā pilina kino. No laila, i ke koho ʻana i kahi kikowaena, pono ʻoe e koho i ke kikowaena kūpono e pili ana i nā koi noi kikoʻī.
