Lub tshuab hluav taws xob tiv thaiv ntawm lub computer chav yog ib feem ntawm kev ruaj ntseg thiab kev tiv thaiv ntawm chav siv computer. Nruab nrab hluav taws xob generated rau ntau yam yog ib qho ntawm feem ntau heev thiab nyuaj rau tshem tawm. Qhov hluav taws xob tsis zoo tsuas yog ua rau kev tsis sib haum, kev ua haujlwm, lossis ua haujlwm yuam kev thaum lub computer khiav, tab sis tej zaum kuj ua rau kev puas tsuaj thiab kev puas tsuaj ntawm tej yam khoom, xws li CMOS, MOS circuits, thiab dual-level circuits. Tsis tas li, hluav taws xob muaj hluav taws xob muaj feem cuam tshuam rau cov khoom siv hluav taws xob sab nraud. Cov khoom tso tawm nrog lub cathode txoj hlua raj, thaum muaj qhov hluav taws xob zoo li qub, tej zaum yuav ua teeb meem duab thiab qhov muag plooj. Lub tshuab hluav taws xob muaj peev xwm tseem ua rau kev ua haujlwm xws li Modem, network card, thiab Fax, thiab lub tshuab luam ntawv tsis luam tawm zoo.
