Piv txwv ntawm thawj tiam computers suav nrog ENIAC , EDVAC, UNIVAC , IBM-701, thiab IBM-650. Cov khoos phis tawj no loj thiab tsis ntseeg siab heev.

Ntawm no, thawj tiam ntawm computers siv rau dab tsi?

Cov thawj tiam ntawm computers siv lub tshuab nqus tsev vacuum ua ib qho tseem ceeb ntawm kev siv tshuab. Lub tshuab nqus tsev vacuum tau dav siv hauv khoos phis tawj los ntawm 1940 txog 1956.

Ib tug kuj yuav nug, dab tsi yog thawj thiab thib ob tiam ntawm lub computer? Cov thawj tiam ntawm electronic khoos phis tawj siv lub tshuab nqus tsev vacuum, uas tsim cov cua sov ntau, yog qhov loj thiab tsis ntseeg. A thib ob tiam ntawm computers , los ntawm lig 1950s thiab 1960s featured circuit boards uas muaj ib tug neeg transistors thiab magnetic core nco.

Tom qab ntawd, qhov twg yog qhov nrov tshaj plaws thawj tiam computer?

IB 650

Qhov loj ntawm thawj tiam computer yog dab tsi?

Ua ntej - Tiam Computer Yam ntxwv. Cov thawj lub computer , ua rau xyoo 1946 nrog lub tshuab nqus tsev, hu ua ENIAC, lossis Electronic Numerical Integrator thiab Khoos phis tawj . Los ntawm cov qauv niaj hnub no, qhov no lub computer tau loj. Nws siv 18,000 lub tshuab nqus tsev, siv 15,000 square feet ntawm qhov chaw hauv pem teb thiab hnyav ntawm 30 tons.

Dab tsi yog cov khoom siv loj tshaj plaws ntawm thawj thiab thib ob tiam ntawm lub tshuab computer?

Thawj tiam (1940-1956) siv lub tshuab nqus tsev vacuum, thiab tiam thib peb (1964-1971) siv cov khoom sib txuas (tab sis tsis yog microprocessors). Mainframes ntawm cov tiam thib ob no siv cov ntawv xuas nrig ntaus rau kev tawm tswv yim thiab tawm thiab 9-khiav 1/2 "magnetic daim kab xev drives rau kev khaws cia, thiab kab tshuab luam ntawv rau cov ntawv luam tawm

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

Dab tsi yog qhov dav thawj qhov kev tshawb nrhiav thiab qhov tob thawj qhov kev tshawb fawb?

BFS sawv rau Breadth First Search. DFS sawv cev rau Kev Tshawb Nrhiav Qhov tob. 2. BFS (Breadth First Search) siv Queue cov qauv ntaub ntawv los nrhiav txoj hauv kev luv tshaj. BFS tuaj yeem siv los nrhiav ib qhov chaw luv tshaj plaws hauv cov duab tsis hnyav, vim tias hauv BFS, peb mus txog qhov kawg uas muaj qhov tsawg kawg nkaus ntawm cov npoo los ntawm qhov chaw vertex

Qhov twg yog qhov kev teeb tsa tus thawj tswj xyuas cov cuab yeej taug qab?

Pib hauv version 1806, CMTrace cav saib cov cuab yeej tau txais kev teeb tsa nrog rau tus neeg siv khoom Configuration Manager. Nws tau ntxiv rau cov neeg siv cov ntawv teev npe, uas yog lub neej ntawd yog %WinDir% CCMCMTrace.exe
