none. none of these machines still operate. the last UNIVAC I was shut down in 1970. the ENIAC was shut down in late 1950s.
uniac meaning is universal automatic computer
one thing they all have in common is that they all use electricity.
ENIAC - Electronic Numerical Integrator And ComputerEDVAC - Electronic Discrete Variable Automatic ComputerUNIVAC - UNIVersal Automatic Computer
The UNIVAC was UNIVersal Automatic Computer, (not ENIAC like another person said) and was used for calculating the results of the 1952 election, saying that Eisenhower would win (which he did!). Invented by J. Presper Eckert & John Mauchly, also the inventors of ENIAC.
EMERAC (an allusion to the early computers UNIVAC and ENIAC)
The development of the ENIAC and UNIVAC I led to significant advancements in computing technology, laying the foundation for modern computers. They helped pioneer the use of electronic components for processing information, making computation faster and more efficient. This progress ultimately set the stage for the widespread adoption of computer technology in various industries.

Electronic Numerical Integrator And ComputerElectronic Discrete Variable Automatic ComputerUNIVersal Automatic Computer
ENIAC (Electronic Numerical Integrator and Computer) was one of the earliest general-purpose electronic computers, developed in the 1940s, and it used vacuum tubes for computation. UNIAC (Universal Automatic Computer), often referred to as UNIVAC, was the first commercially available computer, introduced in the early 1950s, and it utilized transistors instead of vacuum tubes, making it more reliable and efficient. Essentially, ENIAC was a pioneering machine in the realm of computing, while UNIVAC marked the transition to practical commercial computing.
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.
