Cov thawj tiam (1940-1956) siv lub tshuab nqus tsev vacuum, thiab thib peb tiam (1964-1971) siv cov kev sib txuas ua ke (tab sis tsis yog microprocessors). Mainframes ntawm cov tiam thib ob siv punched cards rau cov tswv yim thiab tso zis thiab 9-khiav 1/2 magnetic daim kab xev drives rau massstorage, thiab kab tshuab luam ntawv rau luam tso zis.
Hais txog qhov no, dab tsi yog cov khoom siv loj tshaj plaws ntawm thawj tiam ntawm lub computer?
Punch cards, daim kab xev, thiab daim kab xev sib nqus tau siv los ua nkag thiab cov khoom siv tawm . Cov khoos phis tawj hauv no tiam siv tshuab code raws li programminglanguage.
Ib tug kuj nug, leej twg invented lub 2nd tiam ntawm lub computer? Cov thib ob tiam computers tau tshwm sim nrog kev txhim kho ntawm Transistors. Lub transistor yog invented Xyoo 1947 los ntawm peb tus kws tshawb fawb J. Bardeen, H. W. Brattain thiab W. Shockley. A transistor yog ib qho khoom siv me me ua los ntawm cov khoom siv semiconductor zoo li germanium thiab silicon.
Tib neeg kuj nug, dab tsi yog siv nyob rau hauv thawj tiam ntawm lub computer?
Thawj Tiam : Vacuum Tubes (1940-1956) The thawj lub computer tshuab siv Lub tshuab nqus tsev vacuumtubes rau circuitry thiab sib nqus nruas rau nco, thiab feem ntau enormous, noj tag nrho cov chav. UNIVAC thiab ENIAC khoos phis tawj yog cov piv txwv ntawm ua ntej - tiam suav khoom siv.
Dab tsi yog qhov txawv ntawm thawj tiam thiab tiam thib ob computers?
1. Ib Thawj Tiam ntawm lub computer Lub tshuab nqus tsev vacuum tau siv los ua cov khoom siv sab hauv thiab hauv SecondGeneration transistors tau siv los ua cov khoom siv sab hauv. Hauv thawj tiam lub ntsiab nco yog hauv daim ntawv ntawm magnetic nruas thiab nyob rau hauv tiam thib ob lub ntsiab nco yog hauv tsim RAM thiab ROM.

Dab tsi ntawm cov hauv qab no hais txog lub peev xwm ntawm cov khoom siv computer lossis cov kab ke nthuav dav los pab ntau tus neeg siv yam tsis tau tawg?
Scalability hais txog lub peev xwm ntawm lub khoos phis tawj, cov khoom lag luam, lossis cov txheej txheem nthuav dav los pab ntau tus neeg siv yam tsis muaj kev tawg. IT infrastructure tsuas yog cov cuab yeej siv lub cev tsuas yog xav tau los khiav lag luam
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
Dab tsi yog cov khoom siv lub cev cuam tshuam nrog lub tshuab computer?
Raws li peb tau kawm hauv thawj tshooj, cov ntaub ntawv xov xwm yog tsim los ntawm tsib yam: kho vajtse, software, cov ntaub ntawv, tib neeg, thiab txheej txheem. Cov khoom siv lub cev ntawm cov khoom siv suav - cov uas koj tuaj yeem kov tau tiag tiag - raug xa mus ua khoom siv
Dab tsi yog qhov txawv ntawm thawj tiam thiab thib ob tiam programming lus?
Nyob rau hauv thawj tiam lub ntsiab lub cim xeeb yog nyob rau hauv daim ntawv ntawm sib nqus nruas thiab nyob rau hauv lub thib ob tiam lub ntsiab nco yog nyob rau hauv daim ntawv RAM thiab ROM. Punched card thiab magnetic daim kab xev tau siv nyob rau hauv thawj tiam thiab sib nqus daim kab xev yog siv nyob rau hauv lub thib ob tiam. Cov lus tshuab tau siv thawj zaug thiab cov lus sib dhos tau siv thib ob
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)
