Cov ntsiab lus "cov ntaub ntawv thev naus laus zis" thiab "IT" tau siv dav hauv kev lag luam thiab kev suav. Tib neeg siv cov ntsiab lus dav dav thaum hais txog ntau hom kev ua haujlwm hauv computer, uas qee zaum ua rau lawv tsis meej pem.
Kev Tshawb Fawb Technology yog dab tsi?
A 1958 tsab xov xwm hauv Harvard Kev Tshawb Fawb Kev Lag Luam tau xa mus rau cov ntaub ntawv thev naus laus zis uas suav nrog peb qhov tseem ceeb: kev suav cov ntaub ntawv, kev txiav txim siab, thiab kev lag luam software. Lub sij hawm lub sij hawm no tau cim qhov pib ntawm IT raws li ib cheeb tsam ntawm kev lag luam; qhov tseeb, kab lus no tej zaum coined lub sij hawm.
Ntau xyoo dhau los, ntau lub tuam txhab tsim lub npe hu ua "IT departments" los tswj cov khoos phis tawj thev naus laus zis ntsig txog lawv txoj kev lag luam. Txawm li cas los xij cov chaw haujlwm no tau ua haujlwm dhau los ua qhov tseeb txhais ntawm Cov Ntaub Ntawv Technology, ib qho uas tau hloov zuj zus mus. Niaj hnub no, IT departments muaj kev lav phib xaub hauv thaj chaw xws li kev txhawb nqa khoos phis tawj thev naus laus zis, kev lag luam khoos phis tawj network thiab kev tswj hwm database, kev lag luam software xa tawm, thiab kev ruaj ntseg cov ntaub ntawv.
Tshwj xeeb tshaj yog thaum lub sijhawm dot-com boom ntawm xyoo 1990, Cov Ntaub Ntawv Technology kuj tau cuam tshuam nrog kev suav dhau ntawm cov tswv ntawm IT department. Qhov kev txhais dav dav ntawm IT suav nrog thaj chaw xws li kev txhim kho software, computer systems architecture, thiab kev tswj qhov project.
Information Technology Jobs and Careers
Cov chaw tshaj tawm txoj haujlwm feem ntau siv IT ua ib pawg hauv lawv cov ntaub ntawv. Cov qeb suav nrog ntau txoj haujlwm thoob plaws architecture, engineering, thiab kev tswj hwm kev ua haujlwm. Cov neeg uas muaj haujlwm hauv cov cheeb tsam no feem ntau muaj qib kawm qib siab hauv computer science thiab / lossis cov ntaub ntawv xov xwm. Lawv kuj tseem yuav muaj cov ntawv pov thawj kev lag luam ntsig txog. Cov kev kawm luv luv hauv IT hauv paus tseem tuaj yeem pom hauv online thiab tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov neeg uas xav kom tau txais kev cuam tshuam rau thaj chaw ua ntej cog lus rau nws ua haujlwm.
Ib txoj haujlwm hauv Cov Ntaub Ntawv Technology tuaj yeem koom nrog kev ua haujlwm lossis ua haujlwm IT, pab pawg tsim khoom, lossis pab pawg tshawb fawb. Kev vam meej hauv txoj haujlwm no yuav tsum muaj kev sib koom ua ke ntawm kev txawj ntse thiab kev lag luam.
Teeb meem thiab kev sib tw hauv Cov Ntaub Ntawv Technology
- Raws li kev suav cov tshuab thiab lub peev xwm txuas ntxiv mus thoob ntiaj teb, "cov ntaub ntawv tshaj tawm" tau dhau los ua qhov teeb meem tseem ceeb rau ntau tus kws tshaj lij IT. Kev ua tau zoo ntawm cov ntaub ntawv ntau heev los tsim cov kev txawj ntse ua lag luam yuav tsum muaj ntau lub zog ua haujlwm, cov software tsim nyog, thiab kev txawj ntse ntawm tib neeg.
- Kev sib koom tes thiab kev sib txuas lus tau dhau los ua qhov tseem ceeb rau kev lag luam feem ntau los tswj qhov nyuaj ntawm IT systems. Ntau tus kws tshaj lij IT yog lub luag haujlwm los muab kev pabcuam rau cov neeg siv khoom lag luam uas tsis tau kawm hauv kev sib tham hauv computer lossis lwm yam ntaub ntawv thev naus laus zis tab sis leej twg nyiam siv IT los ua ib qho cuab yeej los ua kom lawv cov haujlwm ua tau zoo.
- Cov teeb meem thiab kev ruaj ntseg network yog qhov kev txhawj xeeb tseem ceeb rau ntau tus thawj coj ua lag luam, vim tias txhua qhov xwm txheej kev nyab xeeb tuaj yeem ua rau lub tuam txhab lub koob npe nrov thiab raug nqi nyiaj ntau.
Computer Networking thiab Information Technology
Vim tias cov tes hauj lwm ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm ntau lub tuam txhab, kev lag luam hauv computer networking cov ncauj lus zoo li cuam tshuam nrog Kev Siv Tshuab. Kev sib koom tes sib txuas uas ua lub luag haujlwm tseem ceeb hauv IT suav nrog:
- Network muaj peev xwm thiab kev ua tau zoo: Qhov nrov ntawm cov yeeb yaj kiab online tau nce ntau qhov kev thov rau network bandwidth ob qho tib si hauv Is Taws Nem thiab hauv IT network. Cov hom tshiab ntawm cov ntawv thov software uas txhawb nqa cov duab zoo dua thiab sib sib zog nqus nrog cov khoos phis tawj kuj tseem yuav tsim cov ntaub ntawv ntau dua thiab yog li kev sib txuas hauv network. Cov ntaub ntawv thev naus laus zis pab pawg yuav tsum npaj kom tsim nyog tsis yog rau lawv lub tuam txhab cov kev xav tau tam sim no tab sis kuj tseem muaj kev loj hlob yav tom ntej no.
- Kev siv txawb thiab wireless: IT network cov thawj coj tam sim no yuav tsum txhawb nqa ntau yam ntawm cov xov tooj smartphones thiab ntsiav tshuaj ntxiv rau cov PCs thiab chaw ua haujlwm. IT ib puag ncig zoo li xav tau kev ua haujlwm siab wireless hotspots nrog kev muaj peev xwm roaming. Hauv cov tsev ua haujlwm loj dua, kev xa tawm tau ua tib zoo npaj thiab sim txhawm rau tshem tawm cov chaw tuag thiab teeb liab cuam tshuam.
- Huab kev pabcuam: Thaum IT khw yav dhau los khaws lawv tus kheej cov chaw ua liaj ua teb rau hosting email thiab kev lag luam databases, qee tus tau tsiv mus rau huab huab ib puag ncig uas cov neeg thib peb hosting muab cov ntaub ntawv. Qhov kev hloov pauv hauv cov qauv kev suav no tau hloov pauv cov qauv ntawm kev khiav tsheb ntawm lub tuam txhab network, tab sis nws kuj yuav tsum tau siv zog loj hauv kev cob qhia cov neeg ua haujlwm ntawm cov ntawv thov tshiab no.
