ENIAC

ENIAC var ein av verdas første programmerbare elektroniske datamaskinar. Namnet stod for Electronic Numerical Integrator and Computer.^[1][2] Han vart utvikla for hæren i USA, og kom i drift i 1945,^[3][4] eit par år etter den britiske maskinen Colossus. Det opphavlege målet var å rekna ut ballistiske tabellar for skyting med artilleri,^[5] men den fyrste oppgåva var å finna kor mogleg det var å laga termonukleære våpen.^[6][7] Maskinen var i kontinuerleg drift fram til 1955.^[2]
