1. Computer Hardware

  1. What is a CPU? What is a GPU?

  2. What is memory and storage?

    • memory = RAM

    • storage = hard disk drive (HDD) or solid state drive (SSD)

  3. What is ROM?

    • What software is stored in ROM on the motherboard?

  4. What is the motherboard and what is a computer "bus"? (later in the semester = what does an audio bus do?)

  5. What are pixels and where do you find them in computer hardware?

  6. What is input/output (I/O or IO) in computing?

  7. What is a transistor, what did it replace, and why is it the most important invention of the 20th Century?

    • think of a transistor as a switch that opens and closes an electrical gate ... with a very small amount of electricity, a transistor can allow or stop large amounts of electricity from going through it

    • What form must data be in for a computer to be able to store and process it?

      • ​Understanding Binary (video)

        • denary = base 10 (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)

        • binary = base 2 (0, 1)

      • Is a paper piano roll an analog or digital medium of storage?

      • List 2 different mediums on which media and/or information has been stored in analog format and 2 different mediums on which binary (digital) data has been stored.

  8. What makes a computer a computer? (4 things)

  9. What is the β€œInternet of Things” (IoT)?

  10. How do you calculate the Current (in Amps) for everything plugged into one circuit breaker in a room? (you do this so you won't plug in more gear than the breaker has electricity to support)
