Evolution of Computers
-
First Modern Day Computer
The first modern day computer was designed by Konrad Zuse. He created it to assist with the complex engineering calculations in his day. -
Atanasoff-Berry
Professor John Atanasoff and his graduate student Clifford Berry built a computer they called the Atanasoff-Berry. The Atanasoff-Berry was much more advanced than the Z1 in that it could handle up to twenty-mine linear calculations simultaneously and out put the results onto a typewriter. -
ENIAC Government Computer
The Electrical Numerical Integrator and Calculator (ENIAC). This computer was able to perform 5,000 calculations per second. The final cost for this computer was 500,000 thousand dollars. -
MARK 1 Computer
In 1948 Williams and Kilburn developed the MARK 1 computer. Although it did not have as much success as the UNIVAC they had great advancements such as the visual monitor. -
UNIVAC Computer
General Electric being the first private company to purchase a computer which they used to calculate payroll. The UNIVAC was much faster than the ENIAC, had a converter that translated punch cards to magnetic tape and produced a 60 word per minute output. -
IBM Computer
In 1954 a company that had up to this time focused on calculators, International Business Machines (IBM), They built the computer called the IBM 701. This computer carried with it multiple innovations, but still held on to a derivation of vacuum tube technology called the Williams tube. -
Electronic Recording Method of Accounting (ERMA) Computer
The ERMA was the last of the major transistor based computers because the integrated circuit had been developed in 1959. -
Introduction of the Microprocessor
Once the microprocessor was incorporated into computer design the evolution of computers went onto a fast track.
