25 volt
Ib yam li ib tug yuav nug, puas yog rs232 muab lub zog?
Txheem Serial ports ua feem ntau tsis yog muab lub zog mus rau peripheral. PX-801 tso cai TSI RS232 peripherals xws li barcode scanners lossis ntsuas ntsuas, kom kos zog lawv xav tau los ntawm Pin 1 lossis Pin 9 ntawm lawv TSI RS232 txuas.
Dab tsi yog qhov txawv ntawm TTL RS 232 thiab RS 232? Cov TTL interface twb tsawg polarity txawv yog tias lub teeb liab poob tsuas yog 2 volts. Txawm tias cov TSI RS232 txheem txhais TSI RS232 los ua ib tug tseeb TSI RS232 interface, thiab TTL yeej tsis ua raws li cov TSI RS232 standard, nyob rau hauv kev xyaum feem ntau ntawm cov TSI RS232 serial ports peb txuas scanners rau yog TTL chaw nres nkoj.
Hais txog qhov no, rs232 serial kev sib txuas lus ua haujlwm li cas?
Cov TSI RS232 yog a kev sib txuas lus cable, feem ntau yog siv los hloov thiab txais cov xwm txheej data between two devices This cable supports two synchronous and asynchronous data transmissions. A serial chaw nres nkoj xa andreceives cov ntaub ntawv ib ntsis ntawm ib lub sij hawm dhau ib tug xaim heev qeeb.
rs232 tswj yog dab tsi?
DTE sawv cev rau Cov Khoom Siv Hluav Taws Xob. Ib qho piv txwv ntawm qhov no yog lub computer. DCE sawv cev rau Data CommunicationsEquipment. Cov TSI RS232 raws tu qauv thiab cable cia lub computer muab lus txib mus rau lub tshuab luam ntawv ntawm voltagesignal.

Dab tsi yog qhov dav thawj qhov kev tshawb nrhiav thiab qhov tob thawj qhov kev tshawb fawb?
BFS sawv rau Breadth First Search. DFS sawv cev rau Kev Tshawb Nrhiav Qhov tob. 2. BFS (Breadth First Search) siv Queue cov qauv ntaub ntawv los nrhiav txoj hauv kev luv tshaj. BFS tuaj yeem siv los nrhiav ib qhov chaw luv tshaj plaws hauv cov duab tsis hnyav, vim tias hauv BFS, peb mus txog qhov kawg uas muaj qhov tsawg kawg nkaus ntawm cov npoo los ntawm qhov chaw vertex
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
Dab tsi yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas thib ob?
Primary index: nyob rau hauv ib tug sequentially order file, qhov Performance index uas nws search key qhia cov sequential order ntawm cov ntaub ntawv. Kuj hu ua clustering index. Secondary index: ib qho Performance index uas nws qhov tseem ceeb tshawb nrhiav qhia qhov kev txiav txim sib txawv ntawm qhov kev txiav txim ntawm cov ntaub ntawv. Kuj hu ua non-clustering index
