1947, Another all-electronic computer was intratual by John von Neumann at the AT & TC (American Telephone and Telegraph company) named EDVAC.


Electronic Distance variable automatic computer. which had stored program facilities.


In 1949, Another All Electronic computer was introduced by Maurice Caillet named EDSAC (Electronic Delay Storage Automatic Computer).


In 1951, Another all-electronic computer also known as the 1st commercially available computer was introduced by J. Presper Eckert with the help of IBM named UniAc/Univac(Universal Automatic Computer), which was commercially used by American census Bureau.
