01Programming and Software Development
This shared-core programming guide covers language constructs, object-oriented design, development processes, and testing. Practice reading and debugging code: predict output, identify a scope or logic error, and choose tests that expose faults.
367 words, about 2 min02Computational Thinking and Problem Solving
This shared-core guide develops decomposition, pattern recognition, abstraction, algorithm design and tracing, and evaluation. Use pseudocode and search/sort scenarios to practice predicting output, identifying missing steps, and justifying complexity.
361 words, about 2 min03Data representation, arrays, lists, trees and graphs
This domain covers how numbers, text, images and sound are encoded in binary, and how collections of data are organised so operations are efficient. Calculations - file sizes, two's complement ranges, normalised floating point - are examined as much as definitions.
595 words, about 3 min04Data, Databases, and Information Retrieval
Data questions move from raw facts to organized, queryable information. In the relational model, tables have rows (records) and columns (attributes); keys enforce identity and relationships.
659 words, about 3 min05Computing Systems
This shared-core guide covers hardware, operating systems, storage, virtualization, system security, and networking. Practice explaining instruction execution, memory, resource management, and controls against specified risks.
727 words, about 4 min06Office and Technology Applications
Office and Technology Applications asks you to match a task to the right tool and to predict what a feature will do. This independent chapter covers spreadsheets, word processing, presentation design, simple databases, collaboration and file formats without asserting an official target blueprint or product-version interface.
476 words, about 2 min07Privacy principles, jurisdiction and responsible information use
Privacy and data protection concern how information about people is collected, used, shared, retained and secured. Confidentiality is one part of this, but a system can keep data secret while collecting far more than its purpose requires.
421 words, about 2 min08Computer architecture, logic and data representation
This domain examines the stored-program machine: how instructions and data share one memory, how the processor fetches and executes them, and how the memory hierarchy and instruction-set design affect performance. Instructions and data share one memory and one set of buses.
