Edvac stands for electronic discrete variable automation computer.it was one of the earliest computers.Edsac stands for electronic delay storage automatic calculator.it was an early british computers.
The development of ENIAC and UNIVAC I prompted an increase in IT research and development that continues into the twenty-first century.
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.
none. none of these machines still operate. the last UNIVAC I was shut down in 1970. the ENIAC was shut down in late 1950s.
designed ENIAC, the first general purpose electronic digital computer, as well as EDVAC, BINAC and UNIVAC I, the first commercial computer made in the United States.
one thing they all have in common is that they all use electricity.
total memory of ENIAC was 20 words all in accumulators; total memory of UNIVAC was 1000 words main memory, 120 words of I/O buffer, and a 10 word "Y" register all in mercury delay lines.words on ENIAC were 10 decimal digits long; words on UNIVAC were 12 alphanumeric characters long.digits on ENIAC were stored in 10 flip-flop ring counters; digits on UNIVAC were stored in 6 flip-flop characters.arithmetic on ENIAC was done by counting pulses sent from one accumulator to another; arithmetic on UNIVAC was done by logic circuits in the single accumulator.programming ENIAC was done by manually interconnecting the various accumulators and special purpose units with cables and individual wires to effectively create a new machine for each problem; programming UNIVAC was done by loading its memory from a magnetic tape containing the previously coded program, these tapes were written by programmers using UNIVAC to help them as is still done with modern computers today.I/O on ENIAC was all done with punchcards; I/O on UNIVAC was all done with magnetic tape.etc.
ENIAC was the First computer that was used to store program.
