Kev Lag Luam Tus Kheej Lub Tshuab (IPC) yog lub lag luam tswj xyuas computer. Nws yog cov lus siv dav dav rau cov khoom siv uas siv tus qauv tsheb npav los tshawb txog thiab tswj cov txheej txheem ntau lawm, cov khoom siv hluav taws xob, thiab cov cuab yeej siv txheej txheem. Kev lag luam hauv lub computer muaj cov cim tseem ceeb hauv lub computer thiab cov yam ntxwv, xws li lub computer motherboard, CPU, hard disk, nco, txuas ntxiv thiab cuam tshuam, nrog rau kev ua haujlwm, tswj network thiab raws tu qauv, xam lub zog, thiab tus phooj ywg-tshuab interface.
Cov khoom lag luam thiab thev naus laus zis ntawm kev lag luam tswj kev lag luam yog qhov tshwj xeeb heev thiab yog cov khoom siv nruab nrab uas muab cov tshuab hlwb hlau ruaj khov, txhim khu kev qha, tsim kho thiab ntse.
Cov pawg tseem ceeb ntawm cov khoos phis tawm yog: IPC (PC bus industrial computer), PLC (programmable tswj system), DCS (faib kev tswj hwm system), FCS (chaw tos tsheb npav system) thiab CNC (cov kev qhia txog zauv tswj). Kev tswj hwm kev lag luam software feem ntau suav nrog peb ntu: software software, tswj kev siv software thiab thov software txhim kho ib puag ncig. Lub system software yog cov qauv tseem ceeb ntawm lwm ob, yog li cuam tshuam rau kev txhim kho kom zoo ntawm qhov system software tsim.
Kev tswj hwm kev lag luam software yog tsim tawm raws li tus neeg siv' s kev lag luam tswj hwm thiab tswj kev xav tau, yog li nws muaj qhov tshwj xeeb.
