Raws li peb tau kawm nyob rau hauv thawj tshooj, ib qho ntaub ntawv qhov system yog ua li ntawm tsib yam: kho vajtse, software, ntaub ntawv, neeg, thiab txheej txheem. Cov lub cev qhov chaw ntawm xam khoom siv - cov uas koj tuaj yeem kov tau tiag tiag - raug xa mus rau kev kho vajtse.
Tsuas yog li ntawd, dab tsi yog cov cuab yeej siv lub cev cuam tshuam nrog lub khoos phis tawj?
Khoos phib tawj kho vajtse muaj xws li lub cev, tangible qhov chaw lossis cov khoom ntawm lub computer, xws li rooj plaub, central processing unit (CPU), saib, keyboard, computer data storage, graphics card, sound card, speaker and motherboard. Los ntawm qhov sib txawv, software yog cov lus qhia uas tuaj yeem khaws thiab khiav los ntawm kev kho vajtse.
Ib sab saum toj no, dab tsi muab kev ua haujlwm ntxiv rau lub operating system? utility software. Muab kev ua haujlwm ntxiv rau lub operating system . qhov system software muaj xws li: kev khiav hauj lwm qhov system software, utilities thiab ntaus ntawv tsav tsheb.
Tsis tas li ntawd, peb txoj haujlwm ua lag luam yog dab tsi uas MIS kev txhawb nqa?
A. Txhawb nqa kev khiav hauj lwm, hloov, thiab ib puag ncig los yog sustainability. Koj nyuam qhuav kawm 24 nqe lus!
Dab tsi software tswj cov ntawv thov software thiab tswj cov cuab yeej kho vajtse ua haujlwm ua ke li cas?
Ib kev khiav hauj lwm qhov system ( OS ) yog software uas tswj lub computer. Nws tswj cov khoom siv kho vajtse, khiav cov ntawv thov, muab ib qho interface rau cov neeg siv, thiab khw muag khoom, khaws cia, thiab tswj cov ntaub ntawv. Feem ntau, ib kev khiav hauj lwm qhov system ua tus neeg nruab nrab ntawm cov ntawv thov thiab kho vajtse (saib daim duab 2-1).

Puas txhais tau tias yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas muab cov lus qhia rau kev siv cov khoom?
Kev them nyiaj yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas txiav txim siab seb qhov khoom siv tau li cas
Puas yog lub tshuab luam ntawv inkjet puas yog lub tshuab luam ntawv cuam tshuam?
Cov piv txwv ntawm cov tshuab luam ntawv cuam tshuam muaj xws li dot matrix, daisy-wheel printers, thiab cov tshuab luam ntawv pob. Dot matrix tshuab luam ntawv ua haujlwm los ntawm kev tawm tsam ib daim phiaj ntawm cov pins tiv thaiv kab. Cov tshuab luam ntawv no, xws li laser thiab inkjet tshuab luam ntawv yog ntau ntsiag to dua li cov tshuab luam ntawv cuam tshuam thiab tuaj yeem luam tawm cov duab kom ntxaws
Yam twg ntawm cov tshuab luam ntawv hauv qab no yog suav tias yog lub tshuab luam ntawv cuam tshuam?
Lub tshuab luam ntawv cuam tshuam yog hais txog ib chav kawm ntawm cov tshuab luam ntawv uas ua haujlwm los ntawm kev ntaus lub taub hau lossis rab koob tiv thaiv tus cwj mem los ua cim rau ntawm daim ntawv. Qhov no suav nrog dot-matrix printers, daisy-wheel printers, thiab kab tshuab luam ntawv
Hauv kev nkag siab dab tsi lub tshuab luam ntawv dot matrix zoo dua li cov tshuab luam ntawv tsis cuam tshuam?
Txhua lub tshuab luam ntawv, xws li lub tshuab luam ntawv laser, lub tshuab luam ntawv ink-jet, LED nplooj ntawv tshuab luam ntawv, uas luam tawm yam tsis muaj kev tawm tsam ntawm daim ntawv, tsis zoo li lub tshuab luam ntawv dot matrix uas ntaus ntawv nrog cov pins me me. Cov tshuab luam ntawv tsis cuam tshuam yog ntsiag to dua li cov tshuab luam ntawv cuam tshuam, thiab tseem nrawm dua vim tsis muaj qhov txav ntawm lub taub hau luam ntawv
Puas yog lub tshuab luam ntawv laser yog ib qho khoom siv lossis cov khoom siv tawm?
Laser Printers yog cov khoom siv tso zis. Txawm li cas los xij, nyob rau hauv 10 xyoo dhau los los yog li ntawd, ntau lub tshuab luam ntawv kuj tau nruab nrog cov tshuab luam ntawv built-in, tig lawv mus rau hauv I / O cov khoom siv (input / output)
