1. Chapter 1 (introduction)

a. List four reasons for studying hardware/low level concepts
b. What are the 3 basic aspects (terminologies) of computer hardware and briefly explain
each term.

2. Chapter 2.1-2.8 Basic Digital Circuits /Logic (1)

a. Use the Web to find out the definition of a resistor in an electric circuit
b. Explain what happens to the resistance between the two ends when you connect
resistors (i) in serial (ii) in parallel
c. What is the role of transistors in basic digital logic?
d. What are the input and output value ranges for 5V logic?
e. Digital logic circuits used in smart phones and other battery-powered devices do not
run on five volts. Search the Web to find out what battery voltage is being used in your
Smartphone.
f. In Boolean logic, ‘+’ and ‘*” mean OR and AND respectively. Make a truth table for (a +
