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.
Edward B. Watters of Newberg, Oregon, points to a legal decision that also calls into question the traditional storyânamely, that the first digital computer was the ENIAC, a machine built in 1945 by J. Presper Eckert and John W. Mauchly of the Moore School of Electrical Engineering at the University of Pennsylvania :tanasoffâs Computer,â Scientific American, August 1988 [not online]. Atanasoffâs first computer was a 12-bit 2-word machine running at 60Hz wall-plug frequency and could add and subtract binary numbers stored in a regenerative memory using a logic unit built with seven triode tubes.
