Conceived the idea of the computer in the 1800's "father of computers"error prone= humans are not perfectdesigned a computer called the "difference engine"- was not completed funding was withdrawndesigned simpler "analytical engine" -not completed due to lack of funding- worked with Ada Lovelace- she created a program that went with the analytical engine- she is first computer programmer, and her program was the first computer program
German engineerDesigned first programable computer- Z1computers augment our ability -"I was too lazy to calculate, so I invented the computer"
Designed and created (with others) "Colossus"Known for proposing the "Turing test"- test to determine the ability of a machines intelligence
Created the Atanasoff-Berry computer (ABC)First general purpose digital computer (some believe this to be ENIAC)3 key elements of the ABC computer (still used today) Binary bits to represent all numbers and data First computer to perform all operation by electronics rather than wheels, ratchets and switches Organized a system in which computation and memory were separated
ENIAC (Electronic Numerical Integrator and Computer)First use was calculations for the Hydrogen bombVacuum tubesLed to first commercial computers (UNIVAC 1) ~ Universal Automatic ComputersVacuum tubes- 1930's - mid 1940's- Unreliable
