Invention Of Electricity
In 1747 Benjamin Franklin began his experiments on electricity. He was convinced that storms were electrical phenomena and proposed a foolhardly metod to prove it. -
Period: to
1st Generation
- Computers were made with vacuum tubes
- Computers were very large
- Computers were very expensive
- Computers needed a huge amount of electricity
-
ENIAC
ENIAC (Electronic Numerical Integrator And Calculator) was the first programmable, electronic, general-purpose digital computer, completed in 1945. There were other computers that had these features, but the ENIAC had all of them in one package. It was Turing-complete and able to solve "a large class of numerical problems" through reprogramming. -
