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.
It used a lot of power and it was very hot! Andâ¦ it was down half the time to replace vacuum tubes gone bad. The ENIAC weighed about as much as all the students in an average middle school altogether! The cell phone is the most common computer that most of us carry around. You may not think of it as a computer, but the functionality is enabled by multiple computers working together. The cell phone is something the designers of the ENIAC could never have imagined. Just getting the ENIAC working took everything they had. The designers of the ENIAC were heckled by some of their colleagues saying that ENIAC was a waste of time and would never work. Iâm thinking they were wrongâ¦.
