Txheej txheem Software . A txheej txheem software (tseem paub tias software methodology) yog ib pawg ntawm cov kev cuam tshuam uas ua rau kev tsim cov software . Software specification (los yog xav tau engineering ): Txhais lub ntsiab functionality ntawm lub software thiab tej kev txwv nyob ib ncig ntawm lawv.
Ntxiv rau qhov no, txhais li cas los ntawm software txheej txheem?
Lub sij hawm software qhia meej rau cov txheej txheem khoos phis tawj, cov txheej txheem thiab cov ntaub ntawv cuam tshuam (Flowcharts, phau ntawv qhia, thiab lwm yam) uas piav qhia txog qhov program thiab lawv yuav siv li cas. A txheej txheem software yog cov txheej txheem ntawm kev ua ub ua no thiab cov txiaj ntsig sib koom ua ke uas tsim tau ib qho software khoom.
Tsis tas li ntawd, 5 theem ntawm SDLC yog dab tsi? System Development Life Cycle Phases:
- 1- Kev Npaj Ua Haujlwm.
- 3-System Design.
- 4- Kev siv thiab xa tawm.
- 5- Kev sim thiab kev sib xyaw ua ke.
- 6- Kev Tswj Xyuas Qhov System.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog software muab piv txwv?
Piv txwv ntawm daim ntawv thov Software Daim ntawv thov feem ntau software cov program siv ntau lab txhua hnub thiab suav nrog: Microsoft suiteof cov khoom lag luam (Office, Excel, Word, PowerPoint, Outlook, thiab lwm yam) Internet browsers xws li Firefox, Safari, thiab Chrome.
Dab tsi yog cov yam ntxwv ntawm cov txheej txheem software?
Rau qhov tseem ceeb tshaj plaws yam ntxwv yog kev ruaj ntseg, raug, reusability, kev cia siab, portability, thiab efficiency. Kev ruaj ntseg yog "qhov yooj yim uas hloov tau los ua kom tau raws li cov kev xav tau tshiab lossis kho qhov tsis zoo" [Balci 1997].

Dab tsi yog qhov tsis zoo ntawm cov txheej txheem txheej txheem?
Ib qho tsis zoo ntawm kev siv Procedural Programming raws li ib txoj hauv kev programming yog qhov tsis muaj peev xwm rov siv tau cov lej thoob plaws hauv qhov program. Yuav tsum rov sau tib hom code ntau zaus thoob plaws ib qho kev pab cuam tuaj yeem ntxiv rau tus nqi tsim kho thiab lub sijhawm ntawm qhov project. Lwm qhov tsis zoo yog qhov nyuaj ntawm kev kuaj xyuas yuam kev
Dab tsi yog qhov xwm txheej hauv ITIL txheej txheem?
Dab tsi yog qhov xwm txheej? ITIL txhais qhov xwm txheej raws li qhov kev cuam tshuam tsis tau npaj tseg rau lossis txo qhov kev pabcuam IT zoo. Cov ntawv cog lus qib kev pabcuam (SLA) txhais cov kev pom zoo-raws li kev pabcuam ntawm tus neeg muab kev pabcuam thiab tus neeg siv khoom. Cov xwm txheej txawv ntawm ob qho teeb meem thiab kev thov
Dab tsi yog software txheej txheem hauv software engineering?
Txheej txheem Software. Cov txheej txheem software (tseem paub raws li software txheej txheem) yog txheej txheej ntawm cov haujlwm cuam tshuam uas ua rau tsim cov software. Cov dej num no yuav koom nrog kev txhim kho software los ntawm kos, lossis, hloov kho qhov system uas twb muaj lawm
Qhov txheej txheem txheej txheem yog dab tsi?
Lub kaw lus tuaj yeem ua modular nyob rau hauv ntau txoj kev. Ib txoj hauv kev yog txheej txheej txheej, uas cov txheej txheem ua haujlwm tau tawg mus rau hauv ntau txheej (qib). Cov txheej hauv qab (txheej 0) id lub kho vajtse; qhov siab tshaj (txheej N) yog tus neeg siv interface. Txoj kev no ua kom yooj yim debugging thiab kev txheeb xyuas qhov system
Dab tsi yog qhov haujlwm ntawm OSI txheej txheej txheej txheej txheej txheem router ua haujlwm li cas?
Hauv Cov Qauv Qhib Kev Sib Txuas Sib Txuas (OSI) kev sib txuas lus, txheej txheej txheej txheem nyob ntawm Txheej 5 thiab tswj kev teeb tsa thiab rhuav tshem ntawm kev sib txuas ntawm ob qhov kev sib txuas lus kawg. Kev sib txuas lus ntawm ob qhov kawg yog hu ua kev sib txuas
