1. Who invented Atanasoff–Berry Computer?Between 1937 and 1942
2. What is the scientists involved?John Atanasoff (Inventor of the concept) and Clifford Berry (Developer and builder)
3. What is the applications?Specifically designed to solve systems of linear equations
4. Why did the ABC use vacuum tubes?Vacuum tubes acted as electronic switches, making the machine faster than old mechanical calculators.
5. How did the ABC store data?It used a rotating drum that could keep 30 numbers, each made of 50 bits, and the data had to be refreshed to stay readable.

Systems of Linear Equations: A set of multiple linear equations that are to be solved simultaneously.
Binary Arithmetic: A base-2 number system using only digits 0 and 1, forming the basis of digital computation.
Vacuum Tubes: Thermionic valves used as electronic switches and amplifiers in early computing devices.
Regenerative Memory: A type of computer memory that requires its contents to be periodically rewritten to prevent data loss.
