- Artificial Intelligence (3 marks)
What argument is Searle making in his Chinese Room discussion about the nature of
intelligence and how it applies to Artificial Intelligence programs?
Searle is making the argument that simple symbol manipulation, e.g.
looking up a symbol in a table and copying over its entry, such as is
done in the Chinese Room discussion, does not represent understanding
the meaning of the symbol. Searle’s argument is that this is what AI
programs do. The crux of the argument is to counter Turing’s position
that if that we need to look at the entity as a black box and if its
performance seems intelligent, that for our purposes, we can call it
intelligent. However, Searle is saying that we cannot simply go by its
performance, we have to go inside the black box and see if its
performance goes beyond mere syntactic symbol manipulation.
(3 marks) - Software Licences (3 marks)
What is the main difference between software that is freeware and open source software?
The main difference between freeware and open source software is
that freeware’s source code is proprietary and not publicly available
whereas open source software’s source code is publicly available and
can be used to create new software.

Give an example of a stochastic board game and of a non-stochastic board game, and
discuss how they exemplify their type of board game.
An example of a stochastic board game is stratego and an example of a
non-stochastic board game is chess. In non-stochastic board games, all
board information is known by both players and the immediate result
of an action can be correctly predicted by both players. In stochastic
board games, some board information is not known by both players and
this usually means that the immediate result of an action cannot be
correctly predicted by both players.
In stratego, there is some board information that is only known by one
player, e.g., the identity of his pieces when they have not attacked or
been attacked, while there is also information that is known to both,
e.g., the location and ownership of pieces. This means that an attacker
does not always know what the outcome of an attack will be before he
executes the attack.
In chess, all board information is known by both players, so each player
knows exactly the immediate result of their action, e.g., if they move a
piece to a specific location containing an enemy piece, then they
capture that piece. - marks)

Describe the roles of the four people involved in preparing scientific tables before the
advent of computers.
Two computers who do the calculations, one comparator who checks
their results agree and a printer who prints the results.
(3 marks) - Computer Networks (3 marks)
Describe the difference between circuit switching and packet switching on a network.
In circuit switching the nodes/computers are directly connected endto-end,
and data is sent along this connection. In packet switching, the
data is broken into packets that are routed independently across the
network.

(3 marks) - Digital Images (3 marks)
How much memory would be required to store a 32-colour bitmap image that is 100
pixels wide and is 16 pixels high? Show all your working. - colours requires 5 bits per pixel (2 ^ 5 = 32)
Number of pixels = 100 * 16
= 1600 pixels
Number of bits required = 5 * 1600
= 8000 bits (1000 bytes)

SECTION B
Answer all questions in this section in the space provided. If you run out of space, please use
the Overflow Sheet and indicate in the allotted space that you have used the Overflow Sheet. - Programming Using Python (15 marks)
(a) The following exponential function can be used to predict the spread of flu-like
diseases:
𝑛𝑛𝑛𝑛𝑛𝑛𝑛𝑛𝑛𝑛𝑛𝑛 𝑜𝑜𝑜𝑜 𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐𝑐 = 2(𝑑𝑑−1)
where d is the day number. The value for Day 0 is defined to be 1.
Write a Python program that calculates and displays the number of flu infections after
a certain number of days. The number of days to predict is entered by the user. You
can assume that the user will always enter an integer value greater than or equal to 1.
Here are two examples of the program running with different values entered by the user.
User input is indicated in the examples with bold and italicized font.
Example 1:
Enter the number of days to predict: 5
The number of cases at day 1 is 1
The number of cases at day 2 is 2
The number of cases at day 3 is 4
The number of cases at day 4 is 8
The number of cases at day 5 is 16
Example 2:
Enter the number of days to predict: 1
The number of cases at day 1 is 1
days = int(input(“Enter the number of days to predict: “))
day = 1
while day <= days:
cases = 2 ** (day – 1)
print(“The number of cases at day “, day, “is”, cases)
day = day + 1

(b) Write a piece of code that prints the visibility rating for the visibility distance entered
by the user at the prompt “Enter the Visibility Distance: “. Use the table
below to determine the visibility rating. You can assume that the user will always
enter a floating-point number (i.e. a float). Two examples are given below.
Visibility Rating Visibility Distance
Good > 6
Fair 3 – 6 (including 3 and 6)
Poor 1 – 3 (including 1 but not 3)
Fog < 1
Example 1:
Enter the Visibility Distance: 0.2
Your Visibility Rating is Fog
Example 2:
Enter the Visibility Distance: 6.0
Your Visibility Rating is Fair
distance = float(input(“Enter the Visibility Distance: “))
if distance > 6:
visibility = “Good”
elif distance >= 3:
visibility = “Fair”
elif distance >= 1:
visibility = “Poor”
else:
visibility = “Fog”
print(“Your Visibility Rating is”, visibility)

(c) In the box below, complete the code that will make the following picture. Assume
that the turtle begins in the middle of the window facing right and that the window is
approximately 500 steps wide. NOTE: You must use a while loop.
import turtle
steps = 100
angle1 = 45
angle2 = 90
number_of_repetitions = 10
step_increment = 10
repeat_number = 0
while repeat_number < number_of_repetitions:
turtle.forward(steps)
turtle.left(angle1)
turtle.forward(steps)
turtle.left(angle1)
turtle.forward(steps)
turtle.left(angle2)
repeat_number = repeat_number + 1
steps = steps + step_increment

is the best formula to use in Cell E11?
= SUM(E4:E10)
(2 marks)
(d) Cell E13 shows the average (mean) number of calories consumed for lunch each day.
What is the best formula to use in Cell E13?
= AVERAGE(E4:E10)
(2 marks)
(e) Cell G13 indicates whether the average number of calories in Cell E13 is under or
over the goal number of calories specified in Cell E14. If the average is less than the
goal value, G13 should show“Under”. If the average is higher than the goal, then
Cell G13 should show“Over”. If the average is equal to the goal then Cell G13 is left
blank. What is the best formula to use in Cell G13?
Note: Your formula must use an IF function.
=IF(E13<E14,”Under”,IF(E13>E14,”Over”,””))
