Computer Science — MYP 4

International Baccalaureate · Ages 14-15

MYP 4 Design projects reach real technical depth. Students build multi-feature applications with structured code, use data structures and file handling, and document the full design cycle for an identified client.

Theory covers computer architecture, data representation, networks, databases and cyber security, alongside the ethical and environmental impact of computing.

For students heading to Diploma Computer Science, this is the year to establish real coding fluency — the Diploma course assumes it and moves quickly into abstract data structures.

Key topics covered

• Application Development — Multi-feature programs with structured, maintainable code.
• Data Structures & Files — Lists, dictionaries, records and reading and writing files.
• Databases — Relational tables, keys, relationships and structured queries.
• Computer Systems — Architecture, memory, storage, operating systems and performance.
• Networks & Cyber Security — Protocols, transmission, encryption, threats and defences.
• Design Cycle Project — Client research, specification, development, testing and evaluation.
