Computing Units 1 and 2
In Computing the Areas of Study are:
Data and graphic solutions – you will conduct an investigation into an issue, practice or event and through the systematic collection, interpretation and manipulation of primary data. You will then create a graphic solution, such as an infographic, that represents the findings. Examples of investigations include the social networking habits of people of different age groups, the heritage of a class of students to three generations and music preferences by genre and favourite artists within each. Graphic solutions could include charts, flowcharts, diagrams, images, hierarchies, animations, maps and timelines.
Networks – you will investigate how networks with wireless capability allow data and information to be exchanged locally and within the global environment. We also examine the hardware and software components and procedures required to connect and maintain a wireless network. We focus on ways in which the security of exchanged and stored data and information can be compromised in wireless networks, in order to understand ways of controlling the networked devices they use. You will apply this technical knowledge to create the design for a network with wireless capability that meets a need or opportunity, identifying its components and how data and information are transmitted. Students use a software tool to depict the components of their network and its interactions.
Collaboration and communication – You will examine how the use of particular information systems within specified contexts can cause tensions and conflicts between different stakeholders. We develop your ability to critically appraise how information systems are used and how individuals can be empowered to shape their use.
Data analysis and visualisation – You will learn to use software tools to access, select and, where appropriate, manipulate authentic data from large data repositories, and to present the key aspects of the data in an appropriate visual form. Once the data has been isolated and checked for its integrity, students create data visualisations that assist in reducing the complexity of data by using designs that illustrate patterns, connections and structure. These visualisations should minimise the effort required by readers to interpret complex data and they need to be clear, usable and relevant. Some data visualisation tools allow presentations to be dynamic and/or interactive. Appropriate visualisation forms include graphs, charts, spatial relationships, maps, histograms and network diagrams (nodes and edges).
Data management – You are introduced to the structure of databases and their applicability in a range of settings. Databases underpin many applications such as borrowing and booking systems, medical records and social media websites. You will develop an understanding of the variety of purposes for databases by exploring the data and information they supply to and receive from systems such as banking, membership, online purchasing and voting systems. They apply systems thinking skills when considering the effects of their interactions with information systems that use databases.
Programming – Your focus will be on using a programming or scripting language that can support object-oriented programming to create working software modules. You will develop skills in interpreting teacher-provided solution requirements and in designing working modules. You can apply methods and techniques for completing a series of small discrete tasks or working modules that use features of a programming or scripting language, including predefined classes.
Who is it for?
If you have broad interest in IT and are interested in developing skills across a range of IT areas, then this may be for you.
What do you do?
Activities you will engage in include:
- database development
- creating data visualisations and infographics
- designing wireless networks

What skills do you need?
Some basic computer skills are helpful and the ability to work independently is important.
What skills do you develop?
This subject develops your skills in logic, it enhances your math skills and design skills, it gives you a better understanding of the holistic approach to problem solving and it will assist you to become an independent learner.
The following textbook is required: Nelson VCE Computing 1 and 2 (6th edition)
Things to think about
Some knowledge of HTML may be beneficial but it is not required.
Things you can do now
Try this HTML tutorial.
Basic PHP tutorials on YouTube will also provide a good head start for the programming section of this course.
