Muaj plaub lub ntsiab IOT, uas qhia peb tias IoT ua haujlwm li cas
- Sensors/Devices.
- Kev sib txuas.
- Kev ua cov ntaub ntawv.
- Tus neeg siv interface.
Tom qab ntawd, dab tsi yog cov khoom hauv Internet ntawm cov khoom?
Dab tsi yog qhov tseem ceeb ntawm Internet ntawm Yam
- Cov cuab yeej ntse thiab sensors - Cov cuab yeej txuas. Cov cuab yeej siv thiab cov sensors yog cov khoom sib txuas ntawm cov cuab yeej txuas.
- Rooj vag. Yees duab: pinterest.com
- Huab. Is Taws Nem ntawm cov khoom tsim cov ntaub ntawv loj heev los ntawm cov khoom siv, cov ntawv thov thiab cov neeg siv uas yuav tsum tau tswj hwm txoj hauv kev zoo.
- Analytics.
- Tus neeg siv interface.
Kuj Paub, IoT system ua haujlwm li cas? Ib IoT system muaj cov sensors/cov cuab yeej uas "tham" rau huab los ntawm qee yam kev sib txuas. Thaum cov ntaub ntawv nkag mus rau hauv huab, software txheej txheem nws thiab tom qab ntawd tej zaum yuav txiav txim siab ua ib qho kev txiav txim, xws li xa cov lus ceeb toom lossis hloov kho cov sensors / khoom siv yam tsis tas yuav tsum muaj rau tus neeg siv.
Kuj Paub, IoT systems yog dab tsi?
Internet ntawm yam, los yog IoT , yog a qhov system ntawm kev sib cuam tshuam cov cuab yeej siv, tshuab tshuab thiab digital, khoom, tsiaj lossis tib neeg uas tau muab cov cim cim tshwj xeeb (UIDs) thiab muaj peev xwm hloov cov ntaub ntawv hauv lub network yam tsis tas yuav tsum muaj kev sib cuam tshuam ntawm tib neeg-rau-tib neeg lossis tib neeg-rau-lub computer.
Vim li cas peb thiaj xav tau Internet ntawm yam khoom?
IoT xav txuas txhua lub peev xwm khoom los sib tham nyob rau hauv internet los muab kev nyab xeeb, kev nplij siab lub neej rau tib neeg. Internet ntawm Yam ( IoT ) ua rau peb lub ntiaj teb ua tau raws li kev sib txuas ua ke. Embedded xam cov khoom siv yuav raug rau internet cawv.

Dab tsi yog qhov xauv thiab qhov tseem ceeb ntawm kev sib raug zoo?
Cia peb muab tus yuam sij thiab xauv Lub xauv hauv qhov ntsiab lus no yog hais txog lub siab ntawm tus neeg uas poob rau hauv kev hlub thiab tus yuam sij yog hais txog tus neeg uas muaj tus neeg ntawd tus yam ntxwv ntawm kev hlub
Peb puas tuaj yeem ntxig ntau qhov NULL qhov tseem ceeb hauv qhov tseem ceeb Oracle?
Ntawd yog: Thaum (1, 1, null) raug tso cai, tab sis tsis pub ntau tshaj ib zaug, kab uas muaj qhov tseem ceeb (null, null, null) hauv peb kab uas ua rau tus yuam sij tshwj xeeb raug tso cai txhua lub sijhawm - ib yam li nyob rau hauv ib kab ke
Dab tsi yog qhov tseem ceeb ntawm Scada system?
Lub SCADA system feem ntau muaj cov ntsiab lus hauv qab no: Cov khoos phis tawj saib xyuas. Tej thaj chaw deb terminal units. Programmable logic controllers. Kev sib txuas lus infrastructure. Tib neeg-tshuab interface. Thawj tiam: 'Monolithic' Thib ob tiam: 'Distributed' Peb tiam: 'Networked
Dab tsi yog qhov tseem ceeb ntawm BIOS Basic Input Output System Dell?
Ib lub khoos phis tawj Basic Input Output System thiab Complementary Metal-Oxide Semiconductor ua ke tuav cov txheej txheem tseem ceeb thiab tseem ceeb: lawv teeb tsa lub khoos phis tawj thiab khau raj lub operating system. BIOS lub luag haujlwm tseem ceeb yog los tswj cov txheej txheem teeb tsa nrog rau kev tsav tsheb thauj khoom thiab kev ua haujlwm booting
Dab tsi yog qhov kev khiav hauj lwm qhov system thiab hais plaub lub luag haujlwm tseem ceeb ntawm kev ua haujlwm?
Ib qho Kev Ua Haujlwm (OS) yog qhov sib txuas ntawm tus neeg siv lub computer thiab lub khoos phis tawj kho vajtse. Lub operating system yog ib qho software uas ua txhua yam haujlwm yooj yim xws li kev tswj cov ntaub ntawv, kev tswj hwm kev nco, kev tswj cov txheej txheem, tuav cov tswv yim thiab tawm, thiab tswj cov khoom siv peripheral xws li disk drives thiab cov tshuab luam ntawv
