   • Information Representation: Binary, hexadecimal, character sets, data types
   • Communication and Internet Technologies: Networking, protocols, data transmission
   • Hardware and Virtual Machines: Computer architecture, CPU, memory, storage devices
   • System Software: Operating systems, utility software
   • Security: Encryption, authentication, firewalls, cybersecurity principles
   • Ethics and Ownership: Intellectual property, ethical considerations in computing
2. Advanced Theory:
   • Database and Data Modeling: SQL, database design, normalization
   • Algorithm Design and Analysis: Searching, sorting, complexity, efficiency
   • Data Structures: Arrays, linked lists, stacks, queues, trees, graphs
   • Software Development: Development lifecycle, methodologies (Agile, Waterfall), documentation
   • Computational Thinking: Problem-solving strategies, abstraction, decomposition
3. Practical Programming:
   • Programming Concepts: Control structures, functions, recursion, error handling
   • Advanced Programming Techniques: Object-oriented programming, data manipulation, file handling
   • Software Engineering: Design, testing, debugging, maintenance
   • Project Work: Real-world problem-solving, application development, project management
