Please refer to information below to answer questions 32 & 33. Computers employ several types of codes to represent character data including ASCII, EBCDIC and Unicode. ASCII requires 7bits to represent each character. A superset of ASCII, called Extended ASCII, uses eight bits to represent each character. The Extended ASCII representation of the letter “A” is 01000001 & “B” is 01000010 The corresponding octal representation of letter “A” is 101 & “B” is 102

Please refer to the following notes to answer question 37 For the past one year, you have been using Ceaser cipher to constantly and securely communicate with your boyfriend/girlfriend via writing letters. This technique was successful in preventing your parents from catching you two, but recently they have come to know of your cipher key and were able to decrypt your letters. So both of you get together again and decide on a mutual and improved Encryption method whereby you are going to encode all of your messages sent using the Vigenere ciphers encryption method. A brief description of Vigenere ciphers is given below. Vigenere ciphers – Is an encryption technique designed by improving the mono-alphabetic encryption (Ceaser cipher). The idea behind Vigenere ciphers is to use multiple mono-alphabetic ciphers, with a specific mono-alphabetic cipher to encode a letter in a specific position in the plaintext message. You agree to use two different Ceaser ciphers, C1 (k=5), C2 (k=19) in the order; C1,C2,C1,C1,C2 and then the pattern will repeat. i.e. the first letter of the plain text will be encoded using C1, second letter using C2, third letter using C1, fourth using C1, fifth one using C2 and then for the sixth one, the entire pattern will repeat again. Plaintext Letter a b c d e f g h i j k l m n o p q r s t u v w x y z C1 (k=5) f g h i j k l m n o p q r s t u v w x y z a b c d e C2 (k=19) t u v w x y z a b c d e f g h i j k l m n o p q r s 37. Match the sentence which best encodes your message to your girlfriend/boyfriend. MESSAGE: We did it A. sleepy am i, away dad and mum. B. bx inw nm C. cy jos nm D. we did it again E. zi did te 38. What is Wi-Fi in terms of computer networking A. type of computer. B. type of network cable C. set of popular technologies and standards for wireless computer networking D. set of computer programs that help people make money on the Internet E. What in Fiji? 39.

46. Introducing TurtleGraphics. Imagine you have a small turtle who responds to certain commands like “move forward some steps”, “move back some steps”, “turn right some angle”, and “turn left some angle”. Imagine also that this turtle carries a pen (or just leaves a trail of green slime wherever it crawls-- the pond he came out of was none too clean). As long as our turtle follows the commands without tiring, we can get it to make rather intricate patterns easily.

Four Basic TurtleGraphics Commands Here is a table of a few of the most common TurtleGraphics procedures, in this case TurtleGraphics commands.

Command Description Example fd steps Moves the turtle forward, in the direction it is facing, by the

specified number of turtle steps. fd 100

bk steps Moves the turtle backward, i.e., exactly opposite to the direction that it's facing, by the specified number of turtle steps.

bk 100

lt angle Turns the turtle counterclockwise by the specified angle measured by a number of degrees (1/360 of a circle).

lt 90

rt angle Turns the turtle clockwise by the specified angle, measured in degrees (1/360 of a circle).

rt 90

The following commands will draw a square as shown (Assume the turtle starts off pointing North):

fd 100 rt 90 fd 100 rt 90 fd 100 rt 90 fd 100 rt 90

Which of the following sequence of commands will draw the pattern below? (Assume step size is 30 and angle making the triangle is 30 and the turtle starts off pointing North)

A. fd 30 lt 30 fd 30 rt 60 fd 30 lt 30 fd 30

lt 30 fd 30 lt 30 fd 30 rt 60 fd 30 lt 30 fd 30 B. rt 90 fd 30 lt 30 fd 30 rt 30 fd 30 lt 30 fd 30

lt 30 fd 30 lt 30 fd 30 rt 30 fd 30 lt 30 fd 30 C. rt 90 fd 30 lt 30 fd 30 rt 60 fd 30 lt 30 fd 30

lt 30 fd 30 lt 30 fd 30 rt 60 fd 30 lt 30 fd 30 D. rt 180 fd 30 lt 30 fd 30 rt 60 fd 30 lt 30 fd 30

lt 30 fd 30 lt 30 fd 30 rt 60 fd 30 lt 30 fd 30 E. None of the above.

47. A programming language has special operators for incrementing or decrementing variables. The operator “++” is the incrementing operator and the operator “--“is the decrementing operator. These operators add or subtract 1 from the value of the variable. But there are two forms of these operators, “prefix” and “postfix”. The term prefix and postfix means the operator appears before and after the variable respectively.

The use of both of these forms for incrementing in an expression is given below. Assume a, i and c are integer variables.

Form Expression Expanded Form Prefix a = ++i + c i = i + 1

a = i + c Postfix a = i++ + c a = i + c

i = i + 1

The same is for decrementing variables.

Hence, for the following expression give the final values for a and i?

i = 10 a = i + 20 + ++i + i--

A. a = 53 i = 11 B. a = 52 i = 10 C. a = 52 i = 11 D. a = 53 i = 10 E. None of the Above 48. For any positive integer n, the number of times that n could be divided by 2 until n = 1 is? (floor(x) returns the

largest integer that is less than or equal to x) A. 2(log )floor n

B. 2(log 1)floor n +C. 2(log 2)floor n +D. 2(log *2)floor nE. All of the above 49. USENET is... A. A set of tools reserved exclusively for Internet administrators B. Short for United States Electronic Network C. A bulletin board system that allows for posting and responding to messages on the Internet D. A precursor to the Internet that is now obsolete E. All of the Above 50. Why were punching cards invented? A. To tabulate the US census data in 1890 more efficiently. B. Demand for better statistics during World War I C. Military demands during the 1920s required large amounts of data. D. All of the above E. None of the above
