3. 1942

4. John Atanasov and his graduate student Clifford Berry

5. it is a machine that stores data in digital format and performs operations with this data using mathematical manipulations

Answer 2

1. The first analog computer is believed to have been built in the late 19th century. However, the first practical analog computer was developed in the 1930s by Vannevar Bush and his colleagues at the Massachusetts Institute of Technology (MIT).

2. The MIT analog computer was used for a variety of applications, including the solution of differential equations, the design of electrical circuits, and the simulation of mechanical systems. It was also used for military purposes during World War II, particularly in the design of naval weaponry.

3. The first digital computers appeared in the 1940s. The first large-scale digital computer was the Electronic Numerical Integrator and Computer (ENIAC), which was built at the University of Pennsylvania in 1945.

4. The inventors of the ENIAC were J. Presper Eckert and John Mauchly. However, the concept of the digital computer had been developed by a number of people over the preceding decades, including Alan Turing, John Atanasoff, and Konrad Zuse.

5. The ENIAC was capable of performing calculations at a much faster rate than any previous machine, and it was used for a variety of applications, including ballistic trajectory calculations and nuclear weapons research. It was also used for scientific research, such as the computation of weather patterns and the simulation of fluid dynamics. However, the ENIAC was a specialized machine and was not suitable for general-purpose computing tasks.
