  Leakages
- B.

The first generation of computers used vacuum tubes for its operations. Vacuum tubes were electronic devices that controlled the flow of electric current in a vacuum. They were used as amplifiers and switches in early computers, allowing them to perform calculations and store data. Vacuum tubes were large, fragile, and produced a lot of heat, making early computers bulky and prone to frequent breakdowns. However, they paved the way for the development of more advanced technologies like transistors, which eventually replaced vacuum tubes in later generations of computers.
