Data Representation

Question

What is the denary value of the binary number 1011?

Model Answer

Correct Answer:

11

To convert binary 1011 to denary: (1 × 2³) + (0 × 2²) + (1 × 2¹) + (1 × 2⁰) = 8 + 0 + 2 + 1 = 11

Question

Explain what binary is and why computers use it.

Keywords to include:

binarybase 20 and 1bitsdigital

Your Answer:

Binary is a number system that uses only 0 and 1. Computers use it because electronic circuits can easily represent two states: on or off.

Model Answer

Model Answer:

Binary is a base-2 number system that uses only two digits: 0 and 1. Each digit is called a bit. Computers use binary because electronic circuits can easily represent two distinct states (on/off, high/low voltage), making it the most reliable way to store and process data in digital systems.

Question

Write a Python function that adds two numbers together.

def add_numbers(a, b):
    # Your code here
    pass
Model Answer

Model Answer:

def add_numbers(a, b):
    return a + b

This function takes two parameters and returns their sum using the addition operator.

Question

A router is used to connect devices within a Local Area Network (LAN).

QuestionTrueFalse
A router is used to connect devices within a Local Area Network (LAN).
Model Answer

Correct Answer:

False

A router is used to connect different networks together, not devices within a single LAN. A switch or hub is used to connect devices within a LAN.

Question

A ______ is a named storage location that holds a value, and a ______ is a sequence of characters.

A variable is a named storage location that holds a value, and a string is a sequence of characters.
function
loop
Model Answer

Correct Answer:

  • variable
  • string

A variable stores a value, and a string is a sequence of characters. The order doesn't matter in this case.

Sequence of characters
Model Answer

Correct Matches:

StatementCorrect Match
Whole numbers onlyInteger
Numbers with decimal pointsReal/Float

Ethics

Question

Discuss the ethical implications of artificial intelligence in education. Consider both benefits and concerns.

Keywords to include:

AIeducationethicsprivacybiasautomation

Word count: 25 / 500 (minimum: 100)

AI in education offers personalized learning and can help teachers identify struggling students. However, there are concerns about data privacy and potential bias in algorithms.

Model Answer

Model Answer:

Artificial intelligence in education presents both significant opportunities and ethical challenges. On the positive side, AI can provide personalized learning experiences, adapt to individual student needs, and help teachers identify areas where students need additional support. It can also automate administrative tasks, freeing up time for educators. However, ethical concerns include data privacy - student information must be protected. There's also the risk of algorithmic bias, where AI systems might perpetuate existing inequalities. Additionally, over-reliance on AI could reduce human interaction in learning, which is crucial for social development. Balancing these benefits and concerns requires careful regulation, transparency in how AI systems work, and ensuring that technology enhances rather than replaces the human element in education.

Question

Draw a star network client-server diagram with 3 computers and a printer. Include labels for all components.

Keywords to include:

serverswitchcomputerprintercomputercomputer

Your Drawing Answer:

Student's drawing
Model Answer

Model Answer:

A star network diagram should show: A central switch/hub in the middle, with a server connected to it at the top. Three computers connected to the switch (one on the left, one on the right, one below). A printer connected to the switch. All devices should be labeled clearly. The switch acts as the central connection point in a star topology.
