Cov ntawv siv thev naus laus zis (IT) yog hais txog qhov dav ntawm ntau cov kev cai sib txawv thiab teb cov haujlwm uas cuam tshuam nrog cov thev naus laus zis rau kev tswj, tsim thiab ua cov ntaub ntawv.
Raws li lub ntsiab lus txhais ntawm lub ntiaj teb lub koom haum UNESCO, cov ntaub ntawv siv thev naus laus zis yog txheej txheej kev cuam tshuam nrog kev siv thev naus laus zis, kev tshawb fawb thiab kev tsim kho tshuab, tsim los kawm cov koom haum ua haujlwm zoo tshaj plaws ntawm kev ua haujlwm ntawm cov neeg koom nrog khaws cia thiab ua cov ntaub ntawv; khoos phis tawj thev naus laus zis, cov hau kev kev ua haujlwm thiab kev cuam tshuam cov khoom siv ntau lawm nrog cov tib neeg; cov kev siv ntawm cov khoom siv no. Cov ntaub ntawv thev naus laus zis lawv tus kheej xav tau kev cob qhia multilevel, kev txiav txim siab thaum pib ntawm tus nqi thiab cov thev naus laus zis siab. Lawv qhov kev nqis tes pib nrog software, kev tsim cov ntaub ntawv ntws hauv cov txheej txheem ntawm cov kws qhia tshwj xeeb. Tsis ntev los no, IT feem ntau to taub raws li cov thev naus laus zis thev naus laus zis, vim hais tias kev ua haujlwm ntawm cov ntaub ntawv siv thev naus laus zis yog txuam nrog kev siv cov koos pis tawj thiab software rau khaws cia, ua, tiv thaiv, txais thiab xa cov ntaub ntawv. Cov kws tshaj lij tshwj xeeb hauv daim teb no hu ua Cov Kws Tshaj Lij. Hauv qhov kev nkag siab dav dav, lo lus "xov xwm thev naus laus zis" tsis yog hais txog computer nkaus xwb, tab sis txhua qhov chaw sib kis, khaws thiab siv cov ntaub ntawv. Qhov tshwm sim ntawm cov khoos phis tawj tau ua rau IT theem mus rau theem tshiab Kev tsim kho ntawm IT tau suav tias yog los ntawm 60s ntawm lub xyoo pua nees nkaum nrog kev tshwm sim ntawm cov ntaub ntawv system (IS). Cov ntaub ntawv siv xov xwm yog cov txheej txheem kev ua haujlwm nrog rau kev sib txuas ntawm IT cov cuab yeej thiab cov hau kev siv los ua, khaws thiab tau txais cov ntaub ntawv. Lub ntsiab txuj ci tseem ceeb ntawm IS yog lub khoos phis tawm uas ua raws cov txheej txheem xov xwm thiab muab cov ntaub ntawv rau kev txiav txim siab hauv txhua cheeb tsam. Kev ua raws li IS lub luag haujlwm yog tsis yooj yim sua yam tsis muaj kev paub txog IT oriented rau nws. Cov ntaub ntawv thev naus laus zis, nyob rau hauv lem, muaj nyob sab nraum qhov chaw cov ntaub ntawv xov xwm. Yog li, lub tswvyim ntawm "cov ntaub ntawv siv thev naus laus zis" muaj peev xwm ntau dua, nws qhia txog cov kev nkag siab niaj hnub ntawm cov txheej txheem ntawm kev hloov pauv cov ntaub ntawv hauv zej zog.
