What impact did the transistor have on electronic devices?

• It decreased their size and cost

• It increased their energy consumption

• It made them less reliable

• It reduced their functionality

What is one of the key characteristics of transistors used in computers?

• They have many moving parts

• They consume a lot of power

• They are extremely small and use little power

• They are large and inefficient

How do transistors contribute to the processing power of a CPU?

• The fewer transistors, the more powerful the CPU

• The color of the transistors determines CPU power

• The more transistors a CPU has, the more powerful it is

• Transistors have no impact on CPU power
