Hauv cov cheeb tsam tseem ceeb ntawm kev tshawb fawb thiab kev lag luam ua , txawv cov txheej txheem yog siv rau kev thov ua kauj ruam mus cov ntaub ntawv . Peb lub ntsiab hom ntawm kev ua cov ntaub ntawv peb tab tom tham txog yog tsis siv neeg / phau ntawv, batch, thiab lub sijhawm kev ua cov ntaub ntawv.
Cov lus nug tseem yog, cov piv txwv ntawm kev ua cov ntaub ntawv hluav taws xob yog dab tsi?
Ib piv txwv ntawm lub sijhawm tiag tiag ua yog ua kom muaj kev ruaj ntseg rau cov rooj zaum dav hlau.
Piv txwv ntawm kev ua cov qauv yog:
- kev ua hauv online.
- lub sijhawm ua haujlwm.
- kev faib tawm.
- Sijhawm sib koom.
- Batch ua.
- multiprocessing.
- multitasking.
- kev sib tham sib ua.
Ib yam li ntawd, muaj pes tsawg hom ntaub ntawv lub computer ua tau? Muaj ob tug general hom ntaub ntawv : analog thiab digital. Xwm yog analog, thaum a lub computer yog digital. Alldigital cov ntaub ntawv muab khaws cia ua tus lej binary. Ib qho ntawm feem ntau hom ntaub ntawv yog cov ntawv nyeem, tseem hu ua characterstrings.
Qhov thib ob, koj txhais li cas los ntawm kev ua cov ntaub ntawv hluav taws xob?
EDP ( electronic data processing ), feem ntau siv lub sij hawm rau dab tsi niaj hnub no feem ntau hu ua "IS" (cov ntaub ntawv kev pabcuam lossis cov tshuab) lossis "MIS" (kev tswj xyuas cov ntaub ntawv lossis cov tshuab), yog ua ntawm cov ntaub ntawv los ntawm acomputer thiab nws cov kev pab cuam hauv ib puag ncig koom nrog hluav taws xob kev sib txuas lus.
Dab tsi yog 4 theem ntawm kev ua cov ntaub ntawv?
Plaub theem tseem ceeb ntawm kev ua cov ntaub ntawv yog:
- Cov ntaub ntawv khaws tseg.
- Cov ntaub ntawv nkag.
- Kev ua cov ntaub ntawv.
- Cov ntaub ntawv tso zis.

Yuav ua li cas koj xaim hluav taws xob tiv thaiv hluav taws xob?
Ntxig txhua lub xaim rau hauv lub qhov tsim nyog hauv qhov chaw txais khoom tshiab thiab ceev cov ntsia hlau davhlau ya nyob twg kom ruaj ntseg. Qhwv qhov kawg ntawm cov tooj liab liab lossis ntsuab xaim (hauv av) nyob ib ncig ntawm cov ntsia hlau ntsuab thiab nruj. Maj mam thawb lub qhov hluav taws xob rov qab rau hauv lub thawv thiab ceev cov ntsia hlau mounting
Dab tsi ua rau lub qhov hluav taws xob muaj hluav taws xob tsawg?
Ib qho laj thawj uas lub qhov hluav taws xob yuav muaj lowvoltageis uas nws hnav tawm. Cov hluav taws xob hluav taws xob tuaj yeem hnav tawm tib yam li txhua yam khoom siv lossis cov khoom siv hluav taws xob.Qhov txuas tsis tu ncua thiab tshem tawm cov hlua rau hauv lub qhov hluav taws xob tuaj yeem loosen thiab hnav cov kev sib txuas
Chav hluav taws xob hloov hluav taws xob yog dab tsi?
Chav hloov. ib cheeb tsam uas muaj kev sib dhos ntawm cov khoom siv hluav taws xob rau kev tswj thiab kev tiv thaiv hluav taws xob circuits. chav hloov pauv tuaj yeem cuam tshuam rau lub substation tab sis tsuas muaj cov keyboards xwb. lub ntsiab hloov mus rau cais tawm hluav taws xob yog nyob rau hauv lub ntsiab switchroom
Puas tuaj yeem tiv thaiv hluav taws xob tiv thaiv hluav taws xob?
Surge protectors tiag tiag yuav tiv thaiv cov khoos phis tawj thiab lwm yam khoom siv hluav taws xob los ntawm lub zog hluav taws xob thiab feem ntau cov xob laim nyob deb, tab sis lawv tsis tuaj yeem tiv thaiv lub teeb pom kev ncaj qha los ntawm kev puas tsuaj rau cov khoom siv sib txuas
Puas yog txhua lub tshuab hluav taws xob muaj GFCI qhov hluav taws xob?
Duplex (ob chav) qhov hluav taws xob muaj nyob rau ntawm lub tshuab hluav taws xob nqa tau thiab txhua qhov khoom siv 120 volts. Hauv av txhaum kev tiv thaiv qhov hluav taws xob (GFCI) yog qhov tshwj xeeb ntawm qee cov qauv thiab tiv thaiv tus neeg siv los ntawm hluav taws xob shocks
