· Wish to improve logical reasoning, analytical skills, and digital literacy.
The course is structured around six core topics to provide students with a comprehensive understanding of computer science concepts.
1. Problem Solving
- Understanding algorithms and their purpose.
- Creating, modifying, and evaluating flowcharts and pseudocode.
- Identifying and correcting errors in algorithms.
- Applying decomposition and abstraction to complex problems.
2. Programming
- Writing and debugging code using Python, Java, or C#.
- Understanding programming constructs: loops, selection, and iteration.
- Using variables, constants, functions, and procedures.
- Working with data structures: arrays, lists, and records.
- Handling user input, validation, and file storage.
3. Data Representation and Storage
- Understanding binary and hexadecimal number systems.
- Data representation of text, images, and sound.
- Data compression techniques (lossy and lossless).
- Encryption algorithms (Caesar cipher, Vigenère cipher, and AES encryption).
4. Computer Systems and Hardware
- The components of a computer system (CPU, RAM, storage devices).
- The fetch-execute cycle and how data is processed.
- Understanding operating systems and software development.
- Logic gates and Boolean algebra.
5. Communication and Networking
- Types of networks (LAN, WAN, PAN, VPN) and their structures.
- Network protocols (TCP/IP, HTTP, FTP, IMAP, SMTP, DNS).
- Cybersecurity threats (phishing, malware, hacking, and firewalls).
- The role of encryption in secure communication.
6. The Bigger Picture
- Ethical, legal, and societal impacts of computing.
- The role of artificial intelligence and machine learning.
- Emerging trends in computing (cloud computing, IoT, quantum computing).
- Environmental impacts of digital technology.
The course allows students to gain practical experience in at least one programming language from the following:
- Python
- Java
- C#
Students will apply their coding skills to solve real-world computational problems and develop robust, efficient programs.
The course assesses students based on the following objectives:
| Objective | Description | Weighting |
|---|---|---|
| AO1 | Demonstrate knowledge and understanding of computer science principles | 27.5% |
| AO2 | Apply knowledge to problem-solving and programming tasks | 42.5% |
| AO3 | Analyse problems and develop computational solutions | 30% |
