Cov ntsiab lus "kev siv technology" thiab "IT" yog dav siv hauv kev ua lag luam thiab kev ua lag luam ntawm xam. Cov neeg siv cov ntsiab lus tsim thaum hais txog ntau hom kev siv hauv computer, uas qee zaus lawv cov ntsiab lus.
Cov Ntaub Ntawv Xov Xwm Yog Dab Tsi?
Ib qho 1958 tsab xov xwm hauv Harvard Kev Tshawb Fawb Kev Tshawb Fawb tau xa mus rau cov lus qhia siv technology xws li peb theem ntawm cov ntaub ntawv: computational data processing, kev txiav txim siab kev them nyiaj yug, thiab kev lag luam software. Lub sij hawm no yog cim pib ntawm IT raws li ib cheeb tsam ntawm kev lag luam; nyob rau hauv qhov tseeb, qhov no tsab xov xwm tej zaum coined lub sij hawm.
Tshaj li kev cog lus xyoo, ntau lub lag luam tsim thiaj li hu ua "IT departments" los tswj lub computer technologies txog lawv txoj kev lag luam. Txawm li cas los xij cov chaw no tau ua haujlwm los ua lub ntsiab lus tseeb ntawm Technology, ib qho uas tau hloov zuj zus mus lawm. Niaj hnub no, IT departments muaj lub luag haujlwm ntawm cov chaw zoo li
- kev them nyiaj yug lub tshuab computer
- kev lag luam computer network thiab database cov ntaub ntawv
- lag luam software lag luam
- kev ruaj ntseg cov ntaub ntawv
Tshwj xeeb tshaj yog thaum lub sij hawm teev tseg ntawm xyoo 1990, Cov Ntaub Ntawv Kev Tsim Txuj Ci kuj tau txuam nrog kev sib tw ntawm cov neeg uas nws yog IT departments. Qhov kev qhia ntxiv ntawm IT nws muaj xws li:
- software tsim
- computer systems architecture
- project management
Qhia Technology Cov Hauj Lwm thiab Cov Haujlwm
Txoj hauj lwm xa tawm chaw feem ntau siv IT raws li ib pawg hauv lawv cov ntaub ntawv. Pawg no suav nrog ntau txoj haujlwm ntawm architecture, engineering thiab kev tswj haujlwm. Cov neeg ua haujlwm hauv cov chaw no feem ntau yuav tsum tau kawm qib siab hauv computer science thiab / lossis cov lus qhia. Lawv kuj tseem muaj cov ntawv pov thawj txog kev lag luam. Cov kev kawm luv hauv Ntaus Nce kuj tseem tuaj yeem pom hauv Internet thiab yog qhov tseem ceeb rau cov neeg uas xav kom tau txais qee qhov kev raug mus rau tom teb ua ntej nws ua haujlwm.
Ib txoj hauj lwm hauv Kev Paub Cov Ntaub Ntawv muaj peev xwm koom tes ua haujlwm los yog ua haujlwm ntawm IT, pawg tsim khoom, lossis pab tshawb nrhiav. Muaj kev vam meej hauv txoj haujlwm no yuav tsum yog kev sib txuam ua ke ntawm kev paub thiab kev lag luam.
Teeb Meem thiab Cov Kev Ntxaij nyob hauv Xov Xwm Tshaj Tawm
- Raws li cov txheej txheem kev lag luam thiab kev muaj peev xwm txuas ntxiv mus thoob ntiaj teb, cov ntaub ntawv tshaj tawm tau los ua ib qho tseem ceeb rau ntau tus IT kws tshaj lij. Txuj ua cov ntaub ntawv loj loj los tsim cov lag luam kev lag luam uas yuav tsum tau siv ntau lub hwj chim, kev siv software, thiab kev txawj ntse ntawm tib neeg.
- Kev sib koom tes thiab kev sib txuas lus tau ua rau tseem ceeb rau cov lag luam feem ntau tswj hwm qhov nyuaj ntawm IT systems. Ntau tus IT kws tshaj lij yuav tsum tau muab kev pabcuam rau cov neeg siv lag luam uas tsis raug cob qhia hauv computer network lossis lwm yam kev siv xov xwm, tiam sis nws tsuas yog xav siv qhov kev siv IT los ua lawv txoj haujlwm kom ua tau zoo.
- Qhov system thiab network teeb meem yog thawj qhov kev txhawj xeeb rau ntau lub lag luam cov thawj coj, vim muaj kev ruaj ntseg xwm txheej muaj peev xwm ua puas tsuaj ib lub tuam txhab lub koob npe nrov thiab raug nqi ntau cov nqi ntawm cov nyiaj.
Computer Networking thiab Information Technology
Vim tias tes hauj lwm ua lub luag haujlwm tseem ceeb hauv kev lag luam ntawm ntau lub tuam txhab, kev ua lag luam hauv computer sib koom tes yuav tsum sib txuas nrog Cov Ntaub Ntawv Technology. Tshua tawm tswv yim uas ua si lub luag haujlwm tseem ceeb hauv IT yog muaj xws li:
- Network muaj peev xwm thiab kev ua tau zoo : Cov chaw hauv online video tau zoo heev rau kev thov rau kev siv network bandwidth ob leeg hauv Internet thiab IT networks. Hom tshiab software software uas txhawb kev tshaj li qub thiab kev sib sib zog nqus sib txuas nrog cov koos pis tawj kuj yuav tsim cov nqi ntau dua ntawm cov ntaub ntawv thiab cov chaw khiav tsheb network. Cov ntaub ntawv siv technology yuav tsum npaj kom tsim nyog tsis yog rau lawv lub tuam txhab cov kev xav tau tam sim no tab sis tseem qhov kev loj hlob yav tom ntej.
- Kev siv txawb thiab wireless : IT network cov thawj coj yuav tsum tam sim no txhawb cov dav hlau smartphones thiab ntsiav tshuaj ntxiv rau cov PCs thiab cov chaw ua haujlwm. IT tej kev kawm zoo li yuav tsum tau muaj kev ua haujlwm siab hauv wireless uas muaj peev xwm roaming. Hauv cov chaw ua haujlwm loj, cov kev npaj ua tiav yog npaj ua tiav thiab sim mus tua cov pwm tuag thiab cov teeb liab cuam tshuam.
- Cov kev pab cuam huab : Whereas nws lub khw nyob rau hauv lub dhau los tswj hwm lawv cov teb chaws ua noj ua teb rau hosting email thiab lag luam databases, ib txhia muaj migrated rau huab computing npuas qhov chaw thib peb hosting zov cov ntaub ntawv. Qhov kev hloov hauv kev ua qauv qauv hloov cov qauv ntawm cov tsheb khiav ntawm lub lag luam network, tab sis nws kuj yuav tsum tau siv dag zog rau kev cob qhia cov neeg ua haujlwm ntawm no cov tshiab yug ntawm daim ntaub ntawv.
