What was the size of the ENIAC computer from 1945?
ENIAC was enormous. It occupied the 50-by-30-foot (15-by-9-metre) basement of the Moore School, where its 40 panels were arranged, U-shaped, along three walls. Each panel was about 2 feet wide by 2 feet deep by 8 feet high (0.6 metre by 0.6 metre by 2.4 metres).
How big is the ENIAC computer?
1,800 square feet
ENIAC weighed 30 tons, took up 1,800 square feet of space, and was made of 17,468 vacuum tubes, 1,500 relays, 70,000 resistors, 10,000 capacitors, and nearly five million hand-soldered joints.
How big was the ENIAC computer and memory?
A parallel static magnetic memory system was designed to increase by 100 words the fast access-time memory capacity of the ENIAC. At present the ENIAC has only 20 words of internal memory, in the form of electronic accumulators.
What was the size of the first computer?
From 1939 to 1944 Aiken, in collaboration with IBM, developed his first fully functional computer, known as the Harvard Mark I. The machine, like Babbage’s, was huge: more than 50 feet (15 metres) long, weighing five tons, and consisting of about 750,000 separate parts, it was mostly mechanical.
How many ENIAC computers were made?
It was designed by two people called John Mauchly and J. Presper Eckert. The machine was built out of nearly 17,500 vacuum tubes, 7,200 diodes and many miles of wire….Sources.

What were the dimensions of the Mark I versus the ENIAC?
Mark I was enourmous in size, measuring 8 feet high, 51 feet long and three feet deep. It weighed 5 tons, used 530 miles of wire and 730,000 separate parts….Addition with carry, example:
| Operation | Seconds | Cycles |
|---|---|---|
| Multiplication | 6.0 | 20 |
| Division | 11.4 | 38 |
| Logarithm | 68.4 | 228 |
| sin(x) | 60.0 | 199 |
How much did the ENIAC weigh in kilograms?
27,273 kilograms
The ENIAC weighed 27,273 kilograms and covered 111 square meters. It was 1000 times faster than the Mark I. Even though computers today are still basically counting machines, they are different in almost every way.
How many pounds did the ENIAC weigh?
(An iPhone 6, by contrast, can zip through 25 billion instructions per second.) When the Army declared ENIAC obsolete in 1955, however, the historic invention was treated with scant respect: its 40 panels, each of which weighed an average of 858 pounds, were divvied up and strewn about with little care.
What is ENIAC Computer?
ENIAC stands for Electronic Numerical Integrator and Computer. John Mauchly and J. Presper Eckert built the machine at the University of Pennsylvania at the behest of the U.S. military.
How does 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 much power does an ENIAC use?
By the numbers: “The ENIAC contained 17,468 vacuum tubes, along with 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. It covered 1,800 square feet (167 square meters) of floor space, weighed 30 tons, consumed 160 kilowatts of electrical power.”
Was the ENIAC a stored program computer?
The ENIAC was not a stored-program computer; it is “better described as a collection of electronic adding machines and other arithmetic units, which were originally controlled by a web of large electrical cables” (David Alan Grier, IEEE Annals of the History of Computing, Jul-Sep 2004, p.2).
How did ENIAC perform arithmetic operations?
ENIAC used ten-position ring counters to store digits; each digit required 36 vacuum tubes, 10 of which were the dual triodes making up the flip-flops of the ring counter. Arithmetic was performed by “counting” pulses with the ring counters and generating carry pulses if the counter “wrapped around”,…
How many times can ENIAC do multiplication per second?
ENIAC used 4 of the accumulators (controlled by a special multiplier unit) to perform up to 385 multiplication operations/second; 5 of the accumulators were controlled by a special divider/square-rooter unit to perform up to 40 division operations/second or 3 square root operations/second.
