Daim ntawv thov software kev faib

Daim ntawv thov software yog ib tug txheej txheem thiab qhov kawg ntawm cov creation ntawm cov kev pab cuam tsim los ua kev pab raws qib (daim ntawv sau npe) coj mus rau tus neeg siv cov kev nyiam. Nyob rau ib tug ua haujlwm zoo lub hom phiaj yuav tsum txwv kom muab zais nyob ntawm neeg ua hauj lwm.

Ib suam ntawm PC software

Tej ntaub ntawv system (YOG) yog nyob rau hauv cov kev tswj ntawm yooj yim software (eg, operating system). Daim ntawv thov software ua hauj lwm nyob rau hauv no ib puag ncig thiab muaj:

- ntau yam pob khoom ntawm thov kev pab cuam (PPP);

- EC ua hauj lwm cov neeg siv cov kev pab cuam.

PPP yuav pom raws li ib tug ntxiv txhim kho ntawm cov operating system rau tej daim ntaub ntawv kev taw qhia.
