Gordon Moore made an observation that was so accurate it became known as Moore’s Law. What does Moore’s Law say?

• The number of transistors inside the latest computer chip is doubling every two years

• The number of transistors inside the latest computer chip is quadrupling every four years and it still seems to be happening

• The number of transistors inside the latest computer chip is doubling every four years and it still seems to be happening

• The number of transistors inside the latest computer chip is quadrupling every two years and it still seems to be happening

What is the problem with Moore’s Law in the future?

• Transistors are becoming so small that as they shrink further they will no longer work properly

• Transistors will be too quick for humans to see what they have done

• Transistors will eventually become redundant

• Transistors soon won't be compatible with the latest CPUs
