Description:
The purpose of this homework is to give you practice with number conversions,
general microcontroller terminology, and computer architecture. It also helps you
with understanding where to find important reference documents that you will rely on
throughout the course! Please show all work necessary to solve each of the problems.
You will receive partial credit for showing your work. You must type your solutions
and submit them electronically!
