What you'll learn

• 1Command words matter for structuring your answer: 'identify' needs a brief factual point, 'explain' needs a reason with some development, and 'compare' needs you to consider similarities and differences.
• 2For binary and hexadecimal, practise converting quickly between all three number systems, including binary addition and understanding overflow errors.
• 3Trace tables become more complex with nested loops and selection statements, so you must carefully track each variable's value on every single pass through the code.
• 4When writing pseudocode, use clear structures such as IF, WHILE, FOR, and function calls, and make sure your logic actually solves the stated problem correctly.
• 5Networks and security scenario questions often expect you to apply knowledge to a specific situation, such as recommending a suitable network topology or security measure for a described organisation.
