Computer Science Expertise is a 3-year program that prepares students to work as entry-stage software program builders in small, medium or giant enterprises. The US Military asked Bell Laboratories to design a machine to assist in testing its M-9 gun director, a type of analog computer that goals large guns to their targets. Mathematician George Stibitz recommends utilizing a relay-based calculator for the challenge. The outcome was the Relay Interpolator, later known as the Bell Labs Mannequin II. The Relay Interpolator used 440 relays, and because it was programmable by paper tape, was used for different functions following the war.
