Who were the ENIAC six?
Who were the ENIAC six?
ENIAC’s six primary programmers, Kay McNulty, Betty Jennings, Betty Snyder, Marlyn Wescoff, Fran Bilas and Ruth Lichterman, not only determined how to input ENIAC programs, but also developed an understanding of ENIAC’s inner workings.
What is the history of ENIAC?
The result was ENIAC (Electronic Numerical Integrator And Computer), built between 1943 and 1945—the first large-scale computer to run at electronic speed without being slowed by any mechanical parts.
How many vacuum tubes did the ENIAC have?
19,000 vacuum tubes
The machine contained 19,000 vacuum tubes, 1500 relays, and several hundred thousand resistors, capacitors, and conductors. There were 20 accumulators, each capable of storing a 10 digit number. The ENIAC could perform about 5000 additions or 50 multiplications in one second.
What was the main contribution of ENIAC programmers?
The ENIAC programmers’ work included the development of concepts like subroutines and nesting. Jean Bartik would later lead a team to turn the ENIAC into a stored program computer in the late 1940s.
What is the difference between ENIAC and Univac?
UNIVAC is the name of a line of electronic digital stored-program computers. UNIVAC is an acronym for UNIVersal Automatic Computer. ENIAC (Electronic Numerical Integrator And Computer) was the world’s first general-purpose computer.
Where was ENIAC invented?
Moore School of Electrical Engineering
ENIAC/Manufacturers
Who invented vacuum tubes?
John Ambrose Fleming
Vacuum tube/Inventors
1904: British engineer John Ambrose Fleming invents and patents the thermionic valve, the first vacuum tube. With this advance, the age of modern wireless electronics is born.
What is the difference between the Mark 1 and the Eniac?
The difference between the two is that when Addition Mode is chosen, ENIAC goes through a whole addition cycle and with Pulse Mode, the machine produces one pulse at a time.
