Ib daim ntawv thov (lossis application program) yog qhov kev kawm uas lub hom phiaj yog ua haujlwm rau cov neeg siv khoom. Feem ntau, cov ntawv thov siv cov txheej txheem ua haujlwm los nkag rau lub koos pis tawj.
Muaj cov kev faib raws li hauv qab no ntawm cov ntawv thov raws li lawv hom:
- lub hom phiaj dav dav;
- lub hom phiaj tshwj xeeb;
- theem kev tshaj lij.
Cov ntawv thov dav dav muaj xws li:
- nraaj editor;
- cov ntawv kho;
- tshuab rau txheej tshuab computer;
- cov ntaub ntawv tswj kev ceev nrooj (DBMS).
Cov ntaub ntawv thov tshwj xeeb suav nrog:
- Cov ntawv thov multimedia (rau tsim lossis kho cov suab thiab cov suab, cov neeg ua si, thiab lwm yam);
- cov kws paub haujlwm;
- hypertext systems (piv txwv li cov kev pabcuam tshuab thiab phau ntawv txhais lus);
- cov ntsiab lus tswj tshuab (CMS).
Daim ntawv thov qib siab muaj xws li:
- Khoos phis tawj-pab tsim qauv (CAD);
- qhov chaw ua haujlwm tsis siv neeg (AWP);
- tshuab kaw lus tswj hwm (ACS);
- tshuab kaw lus tswj hwm rau cov txheej txheem thev naus laus zis (ACS TP);
- cov ntawv them nqi;
- Cov xov xwm cheeb tsam;
- kev sib raug zoo ntawm cov neeg siv khoom kev tswj hwm (CRM).
Raws li qhov teev ntawm daim ntawv thov, cov ntawv thov yog subdivided rau hauv software:
- cov koom haum thiab cov chaw lag luam, nrog rau lawv cov kev cais ib tus neeg;
- cov cuab yeej kev lag luam (e-mail servers, DBMS, thiab lwm yam);
- cov ntaub ntawv cov neeg ua haujlwm (pabcuam rau kom tau raws li qhov xav tau ntawm ib tus neeg siv);
- nkag mus rau cov ntsiab lus (piv txwv, browsers, multimedia players, thiab lwm yam);
- kev kawm (lawv tau siv los sim kev paub);
- simulation (simulation ntawm cov tshuab rau science thiab hom phiaj kev kawm, lossis kev lom zem);
- rau kev ua haujlwm nrog kev tshaj xov xwm (cov phiaj xwm txheej, audio, video thiab duab kho kom raug, luam ntawv ua cov programmes, HTML editors, thiab lwm yam);
- tsim qauv thiab engineering (siv hauv kev tsim software thiab kho vajtse).
