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, coj nce 15,000 square feet ntawm pem teb qhov chaw thiab hnyav hauv ib hefty 30 tons.

Yog li ntawd, dab tsi yog qhov chaw cia khoom ntawm thawj tiam computer?

UNIVAC I (1951) yog tus ua ntej kev lag luam lub computer ua nyob rau hauv Teb Chaws Asmeskas, tsim los ntawm tib cov phooj ywg uas tsim ENIAC (J. Presper Eckert thiab John Mauchly). Nws hnyav 7.6 tons, thiab nyob hauv 382 sq ft (35.5 sq m) ntawm qhov chaw hauv pem teb. Nws muaj 1.5 KB ntawm mercury ncua-kab khaws cia , thiab 10 daim kab xev drives (1 MB muaj peev xwm txhua).

Tsis tas li ntawd, cov yam ntxwv ntawm thawj tiam computers yog dab tsi? Cov hauv qab no yog cov yam ntxwv ntawm thawj tiam computers:

  • Lub tshuab nqus tsev vacuum tau siv los ua cov khoom siv hluav taws xob tseem ceeb hauv thawj tiam ntawm computers.
  • Ntau qhov chaw tau nyob los ntawm cov khoos phis tawj no.
  • Qhov ceev tau ib txwm ntsuas hauv milliseconds.

Kuj Paub, vim li cas thawj tiam computers loj loj?

Cov khoos phis tawj pib tau loj loj Feem ntau vim lawv lub cim xeeb cia, txawm tias ib kilo byte ntawm cov ntaub ntawv khaws cia tau khaws cia hauv ib qho loj ntaus ntawv, thiab cov processors kuj tau loj . Tab sis raws li thev naus laus zis nce siab, lub qhov loj thaum kawg tau txo qis thiab ntau dua thiab ntau dua cov khoom siv sib xws tau tsim!

Dab tsi yog thawj tiam ntawm computers siv rau?

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.
