Cov dov txias yog cov txheej txheem uas cov ntawv npuag los yog cov hlua khi tso tawm ntawm cov dov thiab tom qab ntawd yob thiab nyem.
Nws yog cov khoom tau los ntawm txias-nias ib daim ntawv kub kub. Vim tias qhov ntau dhau ntawm cov khaub thuas txias, cov khoom zoo dua yog qhov zoo dua li ntawm cov ntawv kub-dov, thiab tom qab kev kho cua sov, cov cuab yeej zoo tuaj yeem tau txais.
