Correct Answer: Valves
Solution : The correct option is valves.
The first electronic digital computers used vacuum tubes or valves as electronic components. These early computers relied heavily on vacuum tubes to function. These vacuum tubes performed the functions of electrical switches and amplifiers. They could be switched on and off to represent binary 1s and 0s, making digital computing possible. Over 17,000 vacuum tubes were utilised in the ENIAC, which was finished in the 1940s.
