ENIAC: Electronic Numerical Integrator and Computer
ENIAC stands for Electronic Numerical Integrator and Computer. It is the first operational electronic digital computer in the United States, developed by Army Ordnance to compute World War II ballistic firing tables.
ENIAC was a modular computer, composed of individual panels to perform different functions. Twenty of these modules were accumulators that could not only add and subtract, but hold a ten-digit decimal number in memory. Numbers were passed between these units across several general-purpose buses (or trays, as they were called). In order to achieve its high speed, the panels had to send and receive numbers, compute, save the answer and trigger the next operation, all without any moving parts.
Key to its versatility was the ability to branch; it could trigger different operations, depending on the sign of a computed result.
The ENIAC, weighed 30 tons, used 200 kilowatts of electric power and consisted of 18,000 vacuum tubes, 1,500 relays, and hundreds of thousands of resistors, capacitors, and inductors.
The ENIAC used 20 single-number accumulators as primary functional units but also contained special units for multiplication, division, and square roots.
