Pākuʻi kiʻi wikiwiki.ʻO AGP kahi kikoʻī kikoʻī e hiki ai ke hōʻike ʻia nā kiʻi 3D i ka wikiwiki wikiwiki ma nā kamepiula pilikino maʻamau.ʻO AGP kahi kikowaena i hoʻolālā ʻia e hoʻouna i nā kiʻi 3D me ka wikiwiki a me ka maʻalahi.Hoʻohana ʻo ia i ka hoʻomanaʻo nui o kahi kamepiula pilikino maʻamau e hōʻoluʻolu i ke kiʻi i hōʻike ʻia ma ka hōʻike, a kākoʻo i nā ʻenehana kiʻi 3D e like me ka palapala palapala kikokikona, zero buffering a me alpha blending.
60: He aha ka GPRS?He aha ka GSM?He aha ka CDMA?
ʻO GPRS ka General Packet Radio Service, kahi lawelawe lawe lawe hou i kūkulu ʻia ma ka ʻōnaehana GSM e kū nei, i hoʻohana nui ʻia no nā kamaʻilio lekiō;ʻO GSM ka pōkole o ka "GlobalSystemForMobileCommunication" maʻamau (Global Mobile Communication System) i hoʻolaha like ʻia e ka European Commission for Standardization i ka makahiki 1992. Hoʻohana ia i ka ʻenehana kamaʻilio digital a me nā kūlana pūnaewele hui ʻia e hōʻoia i ka maikaʻi o ka kamaʻilio a hiki ke hoʻomohala i nā lawelawe hou no nā mea hoʻohana. .ʻO ka Code Division Multiple Access kahi ʻenehana kamaʻilio uwea ʻokoʻa hou e pili ana i ka ʻenehana spectrum pālahalaha;
61: He aha ka hoʻohana ʻana o ka ʻenehana GPRS no nā pale hōʻike?
Ma ka pūnaeweleʻikepili GPRS e pili ana i ke kamaʻilio kelepona, hōʻikeʻia kaʻikepili o kā mākou hōʻike LED ma o ka GPRS transceiver module, hiki ke hoʻomaopopo i kahi mamao liʻiliʻi o ka laweʻana i kaʻikepili!Hoʻokō i ke kumu o ka mana mamao;
62: He aha ke kamaʻilio RS-232, kamaʻilio RS-485, a me ke kamaʻilio RS-422?He aha nā pōmaikaʻi o kēlā me kēia?
RS-232;RS-485;ʻO RS422 kahi maʻamau maʻamau no nā kamepiula
ʻO ka inoa piha o RS-232 standard (protocol) ʻo ia ka maʻamau EIA-RS-232C, kahi e hōʻike ai ʻo EIA (Electronic Industry Association) i ka American Electronic Industry Association, RS (kūpono ʻia) e hōʻike ana i ka maʻamau i ʻōlelo ʻia, 232 ka helu ʻike, a ʻo C ka hōʻano hou o RS232
He kiʻekiʻe ke kumukūʻai pae hōʻailona o ka interface RS-232, kahi maʻalahi e hōʻino i ka puʻupuʻu o ke kaapuni interface.He haʻahaʻa ka hoʻouna ʻana, a ua kaupalena ʻia ka mamao o ka lawe ʻana, maʻamau i loko o 20M.
Loaʻa iā RS-485 kahi mamao kamaʻilio o nā ʻumi mika a i nā kaukani mika.Hoʻohana ia i ka hoʻoili kaulike a me ka hoʻokipa ʻokoʻa.He mea maʻalahi loa ka RS-485 no ka hoʻopili ʻana i nā helu he nui.
ʻO nā kaʻa kaʻa RS422, RS485 a me RS422 mau kaʻa kaʻa like ma ke kumu.Hoʻouna ʻia lākou a loaʻa i ke ʻano ʻokoʻa, ʻaʻole pono i ka uea honua kikohoʻe.ʻO ka hana ʻokoʻa ke kumu kumu no ka lōʻihi o ka hoʻouna ʻana ma ka helu like, ʻo ia ka ʻokoʻa kumu ma waena o RS232 a me RS232, no ka mea, ʻo RS232 ka hoʻokomo a me ka hoʻopuka hoʻokahi, a ʻo ka liʻiliʻi loa e koi ʻia ke kelepona honua no ka hana duplex.ʻO ka laina hoʻouna a me ka laina loaʻa he ʻekolu laina (asynchronous transmission), a hiki ke hoʻohui ʻia nā laina mana ʻē aʻe e hoʻopau i ka synchronization a me nā hana ʻē aʻe.
Hiki i ka RS422 ke hana i ka duplex piha me ka hoʻopili ʻole ʻana i kekahi i kekahi ma o ʻelua mau pālua wili, ʻoiai ʻo RS485 hiki ke hana i ka hapalua duplex.ʻAʻole hiki ke hoʻouna ʻia a me ka loaʻa ʻana i ka manawa like, akā pono ia i hoʻokahi mau pālua wili.
Hiki iā RS422 a me RS485 ke hoʻouna i 1200 mika ma 19 kpbs.Hiki ke hoʻopili ʻia nā mea hana ma ka laina transceiver hou.
63: He aha ka ʻōnaehana ARM?No ka ʻoihana LED, he aha kona hoʻohana?
He hui kūikawā ʻo ARM (Advanced RISC Machines) i ka hoʻolālā ʻana a me ka hoʻomohala ʻana i nā chips e pili ana i ka ʻenehana RISC (Reduced Instruction Set Computer).Hiki ke noʻonoʻo ʻia ʻo ia ka inoa o kahi hui, ka inoa maʻamau o kahi papa microprocessors, a me ka inoa o kahi ʻenehana.ʻO ka mana hōʻailona a me ka ʻōnaehana hana e pili ana i ka CPU me kēia ʻenehana i kapa ʻia ʻo ARM system.Hiki i ka ʻōnaehana mana kūikawā LED i hana ʻia i ka ʻenehana ARM ke ʻike i ka mana asynchronous.Hiki i nā ʻano kamaʻilio ke komo i ka pūnaewele peer-to-peer, LAN, Internet, a me ke kamaʻilio serial.Loaʻa iā ia kahi kokoke i nā pilina PC a pau;
64: He aha ke kikowaena USB?
ʻO ka pōkole Pelekane o USB ʻo ia ka Universal Serial Bus, kahi i unuhi ʻia ma ka ʻōlelo Kina ʻo "Universal Serial Bus", i ʻike ʻia ʻo Universal Serial Interface.Hiki iā ia ke kākoʻo i ka hoʻopili ʻana i ka wela a hiki ke hoʻopili i nā polokalamu waho 127 PC;Aia ʻelua mau kikowaena kikowaena: USB1.0 a me USB2.0
