Kev ua tiav ntawm qhov kev txiav txim yog qhov nyuaj thiab nyuaj. Nws yog ib qho kev sib txuas ntawm txhua theem ntawm cov kauj ruam, yog li cas cov ntsiab lus tseem ceeb ntawm kev tsim cov khoom ntawm qhov tseeb?
Kev tsim cov txheej txheem ntawm lub cav yog hais txog tag nrho cov txheej txheem ntawm kev tsim cov khoom ntawm raw cov ntaub ntawv (los yog cov khoom tiav ib nrab). Rau kev siv tshuab, nws muaj xws li kev thauj mus los thiab kev txuag cov khoom nyoos, kev npaj rau kev tsim, kev tsim khoom, kev ua haujlwm thiab kev kho cua sov ntawm qhov chaw, sib dhos thiab debugging ntawm cov khoom, tha xim thiab ntim, thiab lwm yam. Cov ntsiab lus ntawm cov txheej txheem ntau lawm ntau heev. Cov tuam txhab niaj hnub no siv cov qauv kev tsim vaj tse thiab cov hau kev los tsim cov khoom tsim thiab qhia cov khoom, thiab suav cov txheej txheem rau kev tsim khoom raws li cov khoom siv nrog cov tswv yim thiab cov zis.
Hauv kev tsim cov txheej txheem, cov txheej txheem hloov tus qauv, qhov loj me, qhov chaw, thiab qhov khoom ntawm qhov khoom ua tau los ua kom tiav ib qho khoom tiav lossis ib qho khoom tiav tiav yog hu ua tus txheej txheem. Nws yog ib feem tseem ceeb ntawm cov txheej txheem ntau lawm. Txoj kev no yuav muab faib ua ntxiv rau hauv kev nrum, kev ntaus, kev thev, kev siv, kev ua haujlwm, sib dhos, thiab lwm yam kev ua. Kev tsim kho tshuab txhua yam feem ntau yog hais txog qhov sib npaug ntawm cov khoom 'cov khoom lag luam thiab cov tshuab sib dhos ua ke. Lwm cov txheej txheem hu ua kev pab. Cov txheej txheem xws li kev thauj mus los, kev khaws cia, cov khoom siv hluav taws xob, kev kho khoom, thiab lwm yam. Txoj kev rov qab yog dua ib qho los sis ob peb txheej txheem. Ib txoj haujlwm muaj ob peb kauj ruam.
Precision cov txheej txheem txheej txheem txheej txheem yog cov txheej txheem yooj yim uas ua cov txheej txheem kev ua tiav. Txoj kev sib txuas lus yog hais txog ib feem ntawm (lossis pab pawg) ntawm cov neeg ua haujlwm, ntawm qhov cuabyeej tshuab (lossis chaw ua haujlwm), tib lub sijhawm ntawm haujlwm (lossis ntau qhov chaw tib lub sijhawm) los ua kom tiav cov txheej txheem. Qhov tseem ceeb ntawm tus txheej txheem ntawm tus txheej txheem yog tias nws tsis hloov
