0. What is the difference between volatile and nonvolatile memory?

1 Which of the following is true. Positive logic is defined as

a) The configuration where the “true” state has a higher voltage than the “false” state.

b) The state where the signal is “high”.

c) The state where the transistor is “on”.

d) The state where the transistor is “off”.

e) None of the above

2 If a voltage on an input of the TM4C123 is between 0 and 1.3 V, how is that input considered?

a) Low or logic “0”

b) Unknown or illegal

c) High or logic “1”

3 If a voltage on an input of the TM4C123 is between 1.3 and 2 V, how is that input considered?

a) Low or logic “0”

b) Unknown or illegal

c) High or logic “1”

4 If a voltage on an input of the TM4C123 is between 2 and 5 V, how is that input considered?

a) Low or logic “0”

b) Unknown or illegal

c) High or logic “1”

5 Calculate the logic expression for each set of inputs A, B, C

 A B C A & (B | C) 01002 = 4 01012 = 5 01102 = 6 01112 = 7 10102 = 10 00012 = 1 11102 = 14 10012 = 9 01112 = 7

6 Calculate the Boolean expression for each set of inputs A, B, C

 A B C A && (B || C) True False False True False True False True False True True False
