Electrical circuit
In what way does electricity flow?
Negative to positive
What electrical component serves as an on-off switch?
Transistor
What were the first transistors?
PNP Transistors

What is the science of designing and organizing the hardware structures of a computer system?
Computer Architecture
What is the brain of the computer?
CPU (Central Processing Unit)
What is Moore’s Law?
The observation that the number of transistors in an integrated circuit doubles every 2 years
What are the steps in the creation of a CPU?
- Deposition - when new layers of material are deposited onto the wafer?
- Exposure - photoresist is applied, areas of the photoresist are exposed to UV light, and exposed areas are removed.
- Etching - when unprotected areas of material are etched away using various chemicals.
- Testing - the wafer is inspected to make sure everything is working on the microchip
