Answer Key: Microprocessor Worksheet

  1. Hardware – anything you can see or touch
    Software – instructions that the hardware runs

  2. Fetch – finds the next instruction to be run
    Decode – interprets the instruction to be run
    Execute – runs the instruction

  3. Transistors (and wires)

  4. Few, Simple, Precise

  5. They can only handle simple instructions, but they can run billions of these simple instructions every second, so the results look amazing

  6. The NXT-G program is compiled into machine language before it is downloaded to the brick

  7. NXT-G is a (very) high level language.  The brick’s processor cannot understand picture blocks, so each picture block gets compiled into many simple instructions the NXT brick’s processor can understand before they are downloaded.
