ENIAC,EDSAC,EDVAC,UNIVAC(I &II) and MARKS1
The edvac came after the eniac (its predecessor). The main difference was that with the eniac if you wanted to complete a certain process different vacuum tubes had to be tampered with, whereas with the edvac john von neumann and others realised that computers could be programmed which meant you didnt have to tamper with the hardware each time you wanted to complete a different a task.
Eniac had a multitude of bugs and crashes, the modern computers have a multitude of bugs and crashes. For the next 10 years no commonalities anymore between ENIAC and the future computers.
EDSAC(1947 - 1949) Von Neumann designed the electronic discrete variable automatic computer(EDSAC) with a memory to hold a stored pogram as well as datas to.

JON Von Neuman
Actually, Maurice Wilkes had built EDSAC chiefly to study Computer programming issues. There might be some other uses too.
University of Cambridge Mathematical Laboratory
EDSAC stands for Electronic Delay Storage Automatic Calculator, a computer built at Cambridge University in England during the late 1940's.
