Raws li kuv lub teb chaws cov qauv "tsim qauv rau cov khoos phis tawj rau cov khoom siv hluav taws xob, cov ntaub ntawv yuav tau muab faib ua peb theem: thiab kev tswj hwm cov ntaub ntawv ntawm cov ntaub ntawv hluav taws xob vim yog cov khoom tsis ua haujlwm.
Theem A yog qhov txhaum -} ntev. Nyob rau lub sijhawm thaum lub system yuav tsum tau ua haujlwm, nws yuav tsum tsis txhob cuam tshuam rau cov ntaub ntawv hluav taws xob kom cuam tshuam vim yog kev ua haujlwm tsis ncaj ncees, kev kho mob sab nraud, kev saib xyuas sab nraud, kev saib xyuas sab nraud thiab kho dua tshiab.
Qib B yog redundant. Nyob rau lub sijhawm thaum lub system yuav tsum tau ua haujlwm, nws yuav tsum tsis txhob cuam tshuam cov ntaub ntawv hluav taws xob kom muaj kev cuam tshuam vim muaj peev xwm ua tsis muaj peev xwm.
Qib C yog qhov yooj yim. Raws li kev ua haujlwm ib txwm ntawm cov khoom siv hauv lub xaib, kev ua haujlwm ntawm cov ntaub ntawv hluav taws xob yuav tsum tau lees tias tsis muaj kev cuam tshuam.
Theem A yog qib siab tshaj plaws, tsuas yog koom nrog cov chav hauv koos pij tawj ntsig txog kev lag luam hauv tebchaws thiab cov neeg lub neej. Cov ntaub ntawv hauv hluav taws xob chav thiab chav tswj tseem ceeb ntawm cov chaw ua haujlwm hauv tebchaws, cov chaw ua haujlwm hauv xov tooj cua, thiab lwm yam hauv chav kawm chav kawm.
Cov ntaub ntawv hauv hluav taws xob thiab chav tswj hwm tseem ceeb, cov chaw tsheb ciav hlau, cov tsev khaws ntaub ntawv loj, cov tsev khaws khoom loj, cov chaw ua haujlwm loj, Chaw Ua Haujlwm Qhov chaw nyob hauv tsev kawm ntawv nyob rau ntawm cov chaw ua haujlwm hauv xeev thiab cov qib kev lag luam thiab cov lag luam loj thiab lwm yam.
Qhov cuam tshuam ntawm kev ua haujlwm ntawm cov ntaub ntawv hluav taws xob hauv chav kawm C computer yuav tsis ua rau ploj ntau dhau. Cov txheej txheem rau kev tsim kho cov chav khoos phis tawm ntawm txhua chav kawm tuaj yeem txiav txim siab txog lawv cov kev xav tau ntawm cov ntaub ntawv hluav taws xob khoos phis tawj ntawm chav tsev.
Cov ansi / TIA Data Center (Chav Khoos phis tawj) tau muab faib ua 4 Qib. Qhov siab dua qib, qhov ntau dua qhov muaj thiab kev ruaj ntseg tau muab.
