in the year 1946‚ the first successful electronic computer called ENIAC was developed and it was the starting point of the current generation of computer FIRST GENERATION ENIAC was the world first successful electronic computer which was develops by the two scientists namely J.P. Eckert and J. W. Mauchy. It was the beginning of first generation computer. The full form of ENIAC is “Electronic Numeric Integrated and Calculator” ENIAC was a very huge and big computer and its weight was 30 tones. It

UNDERSTANDING THE VON NEUMANN ARCHITECTURE THROUGH THE HISTORY AND DEVELOPMENT OF THE PERSONAL COMPUTER I. Executive Summary From the creation of the EDVAC to the development of the personal computer‚ the Von Neumann architecture has guided generations of computer experts in designing efficient computers. To fully understand the concepts and properties of the Von Neumann architecture‚ an analysis on the history and development of the personal computer was selected. This case study includes the

The Evolution of the computer age First Generation (vacuum tube age) First computer called ENIAC (electronic numerical integrator and computer) completed in 1946. More advanced computers based on ENIACS called UNIVAC becomes available to purchase in 1951. IBM adds computer to its business and sells over 1000 IMB systems in 1951-1953.

by a team at the University of Pennsylvania ’s Moore School of Engineering. This team was headed by John Mauchly and J. Presper Eckert‚ who named the new machine ENIAC‚ for Electronic Numerical Integrator and Calculator. ENIAC was hardly a personal computer‚ occupying a large room and weighing about 33 tons. By today ’s standards‚ ENIAC was extremely slow‚ unreliable‚ and expensive to operate. In 1945‚ on the other hand‚ it was considered a marvel. Over the next 30 years‚ computers became smaller

A Brief History Of Computers The history of computers starts out about 2000 years ago‚ at the birth of the abacus‚ a wooden rack holding two horizontal wires with beads strung on them. When these beads are moved around‚ according to programming rules memorized by the user‚ all regular arithmetic problems can be done. Another important invention around the same time was the Astrolabe‚ used for navigation. Blaise Pascal is usually credited for building the first digital computer in 1642. It added

closer to a modern computer‚ but is really just a large calculator driven by a camshaft with no stored programs. This massive computer filled a large room and was a joint effort between Harvard University and IBM. ENIAC • Another important computer dating from the 1940s is the ENIAC‚ which was built between 1943 and 1945. ENIA (Electronic Numerical Integrator and Calculator) was a project of the University of Pennsylvania‚ and spanned many rooms and used nearly 20‚000 vacuum tubes. The Dawn of

Turing’s works are still referred to by computer scientists today. Finally in 1945 the first computer as we know it today was completed‚ ENIAC as it was called could perform calculations in hours which would take a human years to finish. ENIAC had plenty of drawbacks though‚ first and foremost its size‚ and secondly the 18‚000 tubes it took to run it. ENIAC and UNIVAC‚ which came shortly after‚ were indisputably the greatest advances in technology of all time‚ but they were still useless to the
