Explanation:
Detailed explanation-1: -The Harvard Mark 1 was an early electromechanical computer. It used punched tape and a series of switches and drive shafts to automatically perform calculations and was also known as the IBM Automatic Sequence Controlled Calculator (ASCC).
Detailed explanation-2: -It weighed about 9, 445 pounds (4.7 short tons; 4.3 t). The basic calculating units had to be synchronized and powered mechanically, so they were operated by a 50-foot (15 m) drive shaft coupled to a 5 horsepower (3.7 kW) electric motor, which served as the main power source and system clock.
