WHO IS JOHN VON NEUMANN?

JOHN VON NEUMANN On 1903, John Von Neumann was born in Budapest, Hungary He was a genius in Mathematics John Von Neumann received his diploma in Chemical Engineering in 1925 Completing his doctoral degree in Mathematics in 1928

WHAT DID HE DO? JOHN VON NEUMANN’S ARCHITECTURE ENIAC ( ELECTRICAL NUMERICAL INTERGRATOR AND CALCULATOR )

WHAT IS JOHN VON NEUMANN’S ARCHITECTURE? FOUR MAIN PARTS THE MEMORY ARITHMETIC UNIT CONTROL UNIT INPUT/OUTPUT(I/O) DEVICES

HOW ITS WORK?

ENIAC ENIAC is being used by American military for calculating the artillery-firing tables, setting used for different weapons under various conditions for target accuracy during the war. Its is being used for doing calculation for design of hydrogen bomb, weather prediction, etc after the war by the military

ENIAC It is being design & build by John Mauchly & John Presper Ecker Commonly mistaken by people, ENIAC is one of Von Neumann’s invention. John Von Neumann contribute by developed two important concepts to it

ENIAC The ENIAC used 18,000 vacuum tube, 1,800 square feet of floor space and it consumed 180,000 watts of electrical power. To program the ENIAC you had to arrange the patch cords and setting of 3000 switches.

WHAT HIS INFLUENCES TODAY? Most of the computer have the basic concepts of John Von Neumann’s Architecture. But very few of them have pure John Von Neumann’s Architecture. John Von Neumann’s Architecture spend a lot time moving data to and from the memory, it slows down the computer. So engineers often add another step to it.
