Validation of programs is used to check that data is

  1. In right format

  2. Of right type

  3. Within possible value ranges

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Data validation is a process of ensuring data have undergone data cleansing to ensure they have data quality i.e they are both correct and useful. Apart from data cleansing the data must be within possible value range that ensures smooth and effective functioning of the space satellite. Hence all the three option are correct.

In macro programming, the objects using individual instructions called ______-oriented actions are manipulated.

  1. forms

  2. pages

  3. queries

  4. macro
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In macro programming, the objects using individual instructions called macro-oriented actions are manipulated. A macro is a list of macro-oriented actions that run as a unit. Access provides for such macro programming.

Multiple choice

What are functions?

  1. Code that can only be used once in the application

  2. Reusable pieces of code that can be called on repeatedly.

  3. A special type of variable

  4. Indefinite arrays
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Functions are blocks of organized, reusable code that perform a single, related action. They allow for modularity and avoid code repetition.

Multiple choice

In Python, what data type do comparisons generate?

  1. Integers

  2. Floats

  3. Numbers

  4. Booleans
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Comparison operators in Python (like ==, !=, <, >) evaluate the relationship between values and return a boolean result, which is either True or False.

Multiple choice

What is control flow? Something that...

  1. makes code more readable

  2. allows us to select between multiple outcomes

  3. allows functions to be called

  4. allows the interpreter to print values to the console
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Control flow refers to the order in which individual statements, instructions, or function calls are executed. It allows programs to make decisions (branching) and repeat actions (looping) based on conditions.

Multiple choice

which of the following does not define iteration?

  1. using a while loop

  2. repetition

  3. using a for loop

  4. start again
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Iteration refers to the process of repeating a block of code. 'Start again' is not a formal definition of iteration in programming.

Multiple choice

which command does NOT have a syntax error?

  1. print("hello)

  2. for i range(10):

  3. for line in file

  4. def myFunction():
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Option D is a valid function definition. Option A is missing a closing quote, B is missing the 'in' keyword, and C is missing a colon.

Multiple choice

What is a for loop an example of?

  1. Selection

  2. Iteration

  3. Sequence

  4. Variables
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A for loop is a fundamental programming structure used to repeat a block of code multiple times, which is the definition of iteration. Selection refers to conditional logic (if statements), and sequence refers to the order of execution.

Multiple choice

Which of these is a variable?

  1. print()

  2. float()

  3. num1 = 9

  4. int()
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A variable is a named storage location for data. In 'num1 = 9', 'num1' is the variable name being assigned the value 9. The other options are function calls or type conversion functions.

Multiple choice

float is a data type.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Float is a fundamental data type in Python and many other languages used to store numbers that have fractional parts.
