Demonstrate understanding of advanced concepts from computer science
This standard asks you to understand three big ideas from computer science: how computers represent different types of data using bits, how information gets encoded (compressed, protected from errors, or encrypted), and what makes computer interfaces easy or hard to use. You'll need to describe these concepts, explain why they matter, and evaluate real examples.
You describe the main ideas (data representation, encoding types, and usability heuristics) and give basic examples of how they work in real systems.
You compare different approaches and explain why we choose one method over another; you evaluate an interface or technology and discuss specific advantages and disadvantages using technical reasoning.
You evaluate a complete system in detail, suggesting concrete improvements to interfaces or critically assessing encoding choices; your explanations show you understand the trade-offs involved in real-world design decisions.
