On February, 14, 1946, one of the world's first electronic digital computers—ENIAC—was demonstrated to the public. It was shown at the University of Pennsylvania School of Engineering and Applied Science. The computer was designed by engineer J. Presper Eckert and physicist John Mauchly. ENIAC (Electronic Numerical Integrator and Computer) was 1,000 times faster at calculations than previous electro-mechanical machines. ENIAC was much larger and much slower than modern computers, however. It stood 63 square meters (680 square feet), weighed 27 tons, and took weeks to program.ENIAC is the grandfather of modern computer systems. Its development led to personal computers and the systems that support the Internet.
