The storage media or memory
used in the first generation computer
was vacuum tube. Mark-1 was developed
using vacuum tubes by Howard Aiken in
1937 . Mark -1 had a length of 51 ft
and a height 8 ft . It weighed 32
tones. 18000 vacuum tubes were used
and nearly 7 lakh 50 thousans parts
were assembled in this computer .
Nearly 500 miles long wire
was cut into pieces to connect
different computers . This mainframe
computer took 4.5 seconds for
multiplications operation and 3
additions were performed in 1 second .
Mean while EDVAC, UNIVAC-1 , MARK-11 ,
ENIAC, Z-3, Z-4 etc mainframe were manufactured.
Using many vacuum tubes, ENIAC( Electronic Numerical Integrator and calculator ) was devised by John Mauchly and J. Prresper Eckert jr., in 1946.
This computer was comparatively efficient as it could perform 30 days work done by any other computer in one days at that time.From 1947 to 1955, this computer was used in American offices.
