Extra Credit due Fri 3/22

Because there are no office hours this week, here is an extra credit assignment for Friday:

5 points possible


For 3 points:

Find out what processor your home computer has (Intel or AMD, model name/number? Should be something like Intel Core i5, Intel Core 2 Duo, etc.)

Find out the area (in square millimeters) of the processor die (microchip)

Find out how many transistors are on the processor, and calculate how many transistors per square centimeter


For an extra 2 points (5 points total combined with the above part):
Look up Moore's Law. Briefly summarize it (1-2 sentences)

How many transistors were on the first Intel microprocessor, the 4004? Does the processor in your computer obey Moore's Law? Why or why not?




Homework Due Fri 3/22

Read "The Transistor in a Century of Electronics."

- Write down three key points from the reading
- Write a one-paragraph summary of the reading. Include the following information in your paragraph:
- What discoveries led to the development of the transistor?
- What are some uses for transistors?
- What was the next advancement in transistor technology?
