Qhov zoo ntawm NFC
Yooj yim: Cov yooj yim ntawm kev them nyiaj yog ib qho ntawm qhov zoo tshaj plaws qhov system. NFC ua rau nws yooj yim heev rau cov neeg siv kom them nyiaj tam sim ntawm lawv cov smartphones thiab ntsiav tshuaj, siv lawv lub hnab nyiaj mobile. Cov txheej txheem ntawm kev them nyiaj no kuj yooj yim to taub thiab siv.
Yog li, NFC puas zoo dua Bluetooth?
Lwm qhov txiaj ntsig ntawm NFC technology los nyob rau hauv nws yooj yim ntawm kev siv. Txawm hais tias cov neeg siv yuav tsum nyob ze rau ib leeg los siv NFC technology, nws yog ceev thiab yooj yim rau kev teeb tsa tshaj a Bluetooth kev sib txuas. Bluetooth dostill muab lub teeb liab ntev dua rau kev sib txuas thaum lub sijhawm sib txuas lus thiab hloov chaw.
Tsis tas li ntawd, yog NFC sai dua WIFI? Qhov kev sib cav loj hauv kev pom zoo NFC yog tias nws yuav tsum tau siv zog tsawg dua tshaj Bluetooth. Nws xa cov ntaub ntawv ntawm qhov siab tshaj plaws ntawm 424 kbit / s, piv rau 2.1 Mbit / s nrog Bluetooth 2.1 lossis ib ncig ntawm 1 Mbit / s nrog Bluetooth LowEnergy. Tab sis NFC nws muaj ib qho txiaj ntsig loj: sai dua kev sib txuas.
Xav txog qhov no, NFC ntawm koj lub xov tooj sawv rau dab tsi?
NFC sawv rau Nyob ze Field Communication. Qhov tseem ceeb, nws yog a txoj kev rau koj lub xov tooj sib cuam tshuam nrog ib yam dab tsi nyob ze. Nws ua haujlwm hauv a lub vojvoog ntawm txog 4 cm thiab muab a wireless txuas ntawm koj ntaus ntawv thiab lwm yam.
NFC thiab them nyiaj yog dab tsi?
NFC (ze thaj chaw sib txuas lus) yog thev naus laus zis uas tso cai rau ob lub cuab yeej zoo li koj lub xov tooj thiab a kev them nyiaj terminal-kom sib tham thaum lawv nyob ze ua ke. NFC yog technology uas enables contactless kev them nyiaj.

Dab tsi yog qhov piv txwv ntawm qhov zoo nrog rau qhov zoo network sab nraud cuam tshuam?
Cov piv txwv classic yog xov tooj, qhov twg ntau tus neeg siv nce tus nqi rau txhua tus. Qhov zoo sab nraud yog tsim thaum lub xov tooj tau yuav yam tsis muaj nws tus tswv xav tsim kom muaj txiaj ntsig rau lwm tus neeg siv, tab sis ua li ntawd txawm tias
Dab tsi yog qhov txawv ntawm kev sib raug zoo unary kev sib raug zoo binary thiab kev sib raug zoo ternary?
Kev sib raug zoo tsis sib xws yog thaum ob tus neeg koom hauv kev sib raug zoo yog tib lub koom haum. Piv txwv li: Cov ncauj lus yuav yog qhov yuav tsum tau ua ua ntej rau lwm yam kev kawm. Kev sib raug zoo ternary yog thaum peb lub koom haum koom nrog kev sib raug zoo
Dab tsi yog sparse kem Dab tsi yog qhov zoo thiab qhov tsis zoo?
Koj poob 4 bytes tsis yog ib zaug ib kab; tab sis rau txhua lub cell hauv kab uas tsis yog null. Qhov zoo ntawm SPARSE kem yog: Qhov tsis zoo ntawm SPARSE kem yog: SPARSE kem tsis tuaj yeem siv rau ntawm cov ntawv, ntext, duab, timestamp, geometry, geography lossis cov neeg siv cov ntaub ntawv teev tseg
Dab tsi yog qhov qub txeeg qub teg Dab tsi yog qhov sib txawv ntawm qhov qub txeeg qub teg piav nrog piv txwv?
Inheritance yog ib txoj hauv kev kom tau txais cov yam ntxwv thiab kev coj cwj pwm ntawm ib chav kawm los ntawm lwm chav kawm. Cov chav kawm uas cov tswv cuab tau txais qub txeeg qub teg yog hu ua chav kawm hauv paus, thiab chav kawm uas tau txais cov tswv cuab tam sim no hu ua chav derived. Inheritance siv IS-A kev sib raug zoo
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
