Dual citizenship or dual nationality is simply being a citizen of two countries. The United States allows dual citizenship. For example, if you were born in Mexico you are a native-born Mexican. If you move to the United States and become a naturalized US citizen, you now have dual citizenship.ual citizenship or dual nationality is simply being a citizen of two countries.

This was not a dream of science fiction, but a representation of ENIAC (Electronic Numerical Integrator Analyzer and Computer), the gigantic machine credited with starting the modern computer age. ENIAC, with its 17,468 vacuum tubes, 70,000 resistors, 10,000 capacitors, 1,500 relays, and 6,000 manual switches, was a monument of engineering -- and an energy hog.
When ENIAC was announced in 1946, it was heralded in the press as a Giant Brain.. It had a speed on the order of one thousand (10 3) times faster than that of electro-mechanical machines; this computational power, coupled with general-purpose programmability, excited scientists and industrialists alike.hen ENIAC was announced in 1946, it was heralded in the press as a Giant Brain..
