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

EDVAC:

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

EDSAC:

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

UNIAC:

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.
