What type of logic do most electronic computers use to represent numbers?

• Fuzzy logic

• Boolean logic

• Quantum logic

• Analog logic

What was a major drawback of using vacuum tubes in early computers?

• They were too expensive to produce.

• They were unreliable and consumed a lot of power.

• They were too small to handle large computations.

• They could not be used in cold environments.

Which component in a vacuum tube controls the flow of electrons?

• The cathode

• The anode

• The filament

• The grid

What is a key advantage of transistors over vacuum tubes?

• Transistors can only handle low-frequency signals.

• Transistors are larger and more durable.

• Transistors require heating to function.

• Transistors are more compact and energy-efficient.

How are modern microchips able to surpass the functionality of early computers like ENIAC?

• By relying on manual calculations

• By incorporating billions of transistors in a small space

• By using advanced vacuum tubes

• By using fewer transistors
