What is the Electronic Numerical Integrator And Computer (ENIAC)?

What does ENIAC stand for?

The Electronic Numerical Integrator And Computer (ENIAC) cHanged into the very first preferred-cause Digital Computer. It was designed mostly to calculate artillery firing Tables to be used by america Army’s Ballistic Research Laboratory to help US troops all through World War II. The artillery firing tables helped to predict in which an artillery Shell could hit, permitting troops to hit their targets extra precisely or steer clear of incoming shells. The first Packages written for the ENIAC included a take a look at of the hydrogen bomb’s feasibility.

What Does Electronic Numerical Integrator And Computer Mean?

The Electronic Numerical Integrator And Computer layout and Construction became lead with the aid of Maj. Gen. Gladeon Marcus Barnes and financed by way of the Research and Development Command of the UNited States Army Ordnance Corps. The contract for production turned into signed on June five, 1943 and secret work began in July at the Moore School of Electrical Engineering at the University of Pennsylvania underneath the Codename “Project PX.”

ENIAC was designed and proposed by means of John Mauchly 1942, however the idea was pLagiarized from John Vincent Atanasoff who later won the lawsuit over this rely in 1972. ENIAC become designed to be a Modular Laptop to be composed of person panels that perForm separate Functions, and it became the primary massive-scale laptop to run completely on digital Components with none mechanical elements slowing it down. Because of its layout and 100 kHz cLock, it could do 5000 cycles per second for operations on 10-digit numbers, as the basic Machine Cycle changed into 200 Microseconds lengthy. During one cycle, it is able to write and examine from a check in or add/subtract numbers. Although it became first of all designed for army applications, the ENIAC became extensively utilized to resolve complicated arithmetic, engineering, and physics problems, and was programmed by way of manipulating a series of Switches and cables.

The ENIAC group consisted of:

• John Mauchly – Designer
• J. Presper Eckert – Co-dressMaker
• Thomas Kite Sharpless – Master Programmer
• Robert F. Shaw – Function tables
• Jeffrey Chuan Chu – Square-Rooter/divider
• Arthur Burks – Multiplier
• Harry Huskey – Reader/printer
• Jack Davis – Accumulators

Components of the ENIAC covered:

• 1,468 Vacuum Tubes
• 70,000 Resistors
• 10,000 Capacitors
• 7,200 crystal Diodes
• 1,500 Relays
• five,000,000 hand-soldered Joints
