Year 11

The functions and technical capabilities of systems, how components are configured to form a computer system, and factors which affect the design of an information system, are explored. The compatibility of components, output, bandwidth considerations, and usability, security, health and safety considerations are explored. Evaluations of systems, devices or components are conducted, while acquiring computer hardware knowledge and skills. 

The distinction between data and information, including the different types of data (including text and number) and the varied representation of data within a computer, are addressed. The representation of data types, the graphical representation of data, and how data is stored using a database are also addressed.  

A systems development cycle (SDC) that includes some basic systems engineering and the application of standards is applied. How a developer’s interactions with users affect the development and use of the system is investigated. Various methods of developing software systems and the problems associated with connecting systems in an increasingly global environment are addressed. The different perspectives of users and developers to the development and use of computer-based systems are explored. 

The different types of programming languages are investigated. The basic constructs of sequence, selection and iteration are examined. The analysing and breaking up problems into small, self-contained units for which procedures or functions are created in a programming language are addressed. The passing of parameters to procedures, functions and modules are explored.   

The various structures and components of a network, including the communication media used to combine them, are examined. The convergence of technologies which involves the integration of computers and communication hardware, is investigated. Similarly, the design and creation of networks of various configurations, as well as connecting networks of different types, are investigated. The application of connectivity standards relating to networks and the internet, is addressed. Communication software models and standards; the types, purpose and use of protocols, servers and operating systems in communications; and software and the aspects to consider in network security are explored.
