A Brief History of Personal Computer systems

This crew was advancing by Steve Mauchly and J. Presper Eckert, who named the modern machine ENIAC, for Electric Numerical Integrator and Calculator. ENIAC was hardly an individual computer, living in a large room and considering about thirty-three tons.
