When operating, the ENIAC was silent but you knew it was on as the 18,000 vacuum tubes each generated waste heat like a light bulb and all this heat (174,000 watts of heat) meant that the computer could only be operated in a specially designed room with its own heavy duty air conditioning system.

Why was the ENIAC so important?
The ENIAC is important historically, because it laid the foundations for the modern electronic computing industry. ... The ENIAC was a large-scale, general purpose digital electronic computer. Built out of some 17,468 electronic vacuum tubes, ENIAC was in its time the largest single electronic apparatus in the world.
What was the world's first computer?
ENIAC, in full Electronic Numerical Integrator and Computer, the first programmable general-purpose electronic digital computer, built during World War II by the United States.
How many vacuums did the ENIAC have?
Filling up a 30 X 50 foot room, ENIAC was made of 17, 468 vacuum tubes, 70,000 resistors, and 10,000 capacitors -- not to mention all those lights and switches. Most importantly, the metal giant could add 5,000 numbers in a single second.
How did the ENIAC change the world?
The ENIAC, or Electronic Numerical Integrator and Computer, could churn 5,000 addition problems in one second, far faster than any device yet invented. In February 1946, J. ... In a few years, computers would pop up at universities, government agencies, banks and insurance companies.
Why was the ENIAC created?
In 1946, Mauchly and Eckert developed the Electrical Numerical Integrator And Calculator (ENIAC). The American military sponsored this research because it needed a computer for calculating artillery-firing tables, the settings used for different weapons under varied conditions for target accuracy.
How did the Univac change the world?
It weighed 16,000 pounds, used 5,000 vacuum tubes, and could perform about 1,000 calculations per second. On November 4, 1952, the UNIVAC achieved national fame when it correctly predicted Dwight D. Eisenhower's unexpected landslide victory in the presidential election after only a tiny percentage of the votes were in.
Who invented laptop?
Adam Osborne invented the laptop in 1981. Though Osborne 1 was recognized as the first laptop, the concept of a portable computer was given in 1968 by Alan Kay.
Why is ENIAC considered the first modern computer?
In 1942, physicist John Mauchly proposed an all-electronic calculating machine. ... 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 does the ENIAC computer work?
ENIAC used four of the accumulators (controlled by a special multiplier unit) to perform up to 385 multiplication operations per second; five of the accumulators were controlled by a special divider/square-rooter unit to perform up to 40 division operations per second or three square root operations per second.
How big was the ENIAC computer and how much memory did it have?
ENIAC was enormous. It contained 17,500 vacuum tubes, linked by 500,000 soldered connections. It filled a 50-foot long basement room and weighed 30 tons. Today, a single microchip, no bigger than a fingernail, can do more than those 30 tons of hardware.
How large was the ENIAC computer how much memory did it have?
In 1953, the Burroughs Corporation built a 100-word magnetic-core memory, which added to the ENIAC's memory capabilities, which at the time only held a 20-word internal memory.
What happened to ENIAC?
After eleven years of calculating and processing programs, the ENIAC was retired. Designers John Mauchly and J. ... The ENIAC ran at 5,000 operations a second with a system of plug boards, switches, and punch cards. It occupied 1,000 square feet of floor space.
What was the ENIAC used for in ww2?
The Electronic Numerical Integrator And Computer (ENIAC) was the very first general-purpose electronic computer. It was designed primarily to calculate artillery firing tables to be used by the United States Army's Ballistic Research Laboratory to help US troops during World War II.
What are the advantages of UNIVAC?
UNIVAC's speed outshined all of its competitors—it was thousands of times faster than its rivals—but more importantly, it was among the first “stored program” computers, using magnetic tape, rather than punch cards, to collect and manage data. Up to one million characters could be stored and accessed on magnetic tape.
What happened to UNIVAC?
The successful military supplier bought Remington Rand in 1955, acquiring a computer division eventually known as Sperry UNIVAC. Sperry finally dropped the venerable UNIVAC name in 1984.
What are the differences of 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.
