Questions & Answers

Q: What are transistors and why are they important?

Transistors are small switches that control the flow of electrical current and are essential for computers to process and store information. They play a crucial role in the functioning of microchips and can be organized into integrated circuits.

Q: What is Moore's Law?

Moore's Law predicts that the number of transistors that can fit on a microchip will double every two years, resulting in a significant increase in computing power. It has been a guiding principle in the tech industry for decades.

Q: Why has the exponential growth predicted by Moore's Law slowed down?

The exponential growth of transistors on microchips has slowed down due to limitations in increasing transistor density. The size of the gap between silicon channels, reliability and affordability issues, heat generation, and quantum tunneling are the main challenges.

Q: What are some alternatives to silicon-based transistors?

Graphene is a highly conductive material that could potentially allow for faster electron travel. However, manufacturing challenges need to be overcome. Optical computing, which utilizes photons instead of electrons, is another option but faces difficulties related to photon manipulation, power consumption, and cost.

Summary & Key Takeaways

• Transistors, tiny switches that control electrical current, are the basis for computer operations and can be organized into integrated circuits to process information.

• Moore's Law, which states that the number of transistors on a microchip would double every two years, has not been able to keep up with its exponential growth prediction in recent years.

• The main challenges in increasing transistor density on microchips are the size of the gap between silicon channels, reliability and affordability concerns, heat generation, and quantum tunneling.
