Question 1: Write a simple Python function named 'addNumbers' that takes two numbers as inputs and returns their sum.

Answer: def addNumbers(a, b): return a + b

Question 2: Describe what a function is in programming and give one example of when you might use one.

Answer: A function is a block of code that performs a specific task and can be reused multiple times. For example, a function that calculates the area of a rectangle can be used whenever needed.

Question 3: Complete the following pseudocode to create a function that checks if a number is even. The function should return 'Yes' if even, and 'No' if odd: FUNCTION checkEven(number) IF ________ RETURN 'Yes' ELSE RETURN 'No' END FUNCTION

Answer: number % 2 == 0

Question 4: Draw a logic circuit that represents the AND gate using two inputs and one output. Label the inputs as A and B, and the output as C.

Answer: A correct sketch would show two input lines labeled A and B entering an AND gate symbol, with a single output line labeled C. The AND gate is typically depicted as a D-shaped symbol.

Question 5: Complete the truth table for an OR gate with inputs A and B and output C.

Answer: A | B | C ---|---|--- 0 | 0 | 0 0 | 1 | 1 1 | 0 | 1 1 | 1 | 1

Question 6: A circuit contains two switches connected in series, and a light bulb. Describe how the switches need to be turned on or off for the light to turn on.

Answer: Both switches need to be turned on for the light to turn on. If either switch is off, the circuit is incomplete and the light stays off.

Question 7: Draw a NOT gate and label the input as A and the output as B. Describe what the output B will be if the input A is true.

Answer: A correct sketch shows a triangle with a small circle (inverter symbol), with input labeled A entering the triangle and output labeled B leaving the small circle. If A is true (1), then B will be false (0).

Question 8: Explain how a function differs from a loop in programming.

Answer: A function performs a specific task when called and can be reused, while a loop repeats a block of code multiple times until a condition is met.

Question 9: Sketch a flowchart that shows the decision process for a program that checks if a number is positive, negative, or zero.

Answer: A flowchart with a start symbol, a decision diamond asking 'Is number > 0?', leading to different paths: one for 'Yes' (print 'Positive'), one for 'No' leading to another decision 'Is number < 0?', with paths for 'Yes' (print 'Negative') and 'No' (print 'Zero'), ending with an end symbol.

Question 10: What will be the output of the following code snippet? ```python def multiplyByTwo(n): return n * 2 result = multiplyByTwo(5) print(result) ```

Answer: 10
