that should be demonstrated, and use measurable outcomes and language that students can understand. The rubric below is not meant to be used as a task rubric. It has been produced to assist you to determine the appropriate level of knowledge and understanding of the key concepts presented in the activities for student achievement at each year level. This should be used alongside the Australian Curriculum achievement standards and any school or jurisdiction guidelines for summative assessment purposes. Think of the depth of knowledge and understanding as being a continuum. Students who are operating at a relational level, for example, will also be able to demonstrate the multi-structural knowledge acquisition presented. Quantity of knowledge Quality of understanding Criteria Uni-structural Relational Extended abstract Structure and types of networks Can identify some of the key features of a network, but is unclear on their roles in the system or how data moves between them Understands the route data travels between main components of a network but does not fully understand the purpose of each step; can state different types of networks Can identify important parts of a network and distinguish between them; explains simple reasons for choosing one type of infrastructure over another Can articulate the role of each component in the network and how the entire system is dependent on each performing a specific purpose; can rationalise choice of network infrastructure Understands how decisions around design of networks are affected by multiple factors, and that good designs will incorporate alternative routes for data transmission and redundancy Transmission and structure of data Identifies that networks allow the transmission of data between computers, and that data carries Can explain that data transmission involves more than just the transfer of information and requires metadata to be able to function Understands the information contained within metadata and can explain how it is used to ensure messages Explains the type of information that is stored in metadata and the limitations this introduces in terms of the rate of transfer and the quantity of Draws upon the knowledge they have learned to hypothesise about the nature of data and the challenges inherent in reconstructing it when multiple
some meaning reach their destination message data in each packet data streams are being transferred between nodes in a network Network performance Can identify that different types of physical media change network performance Can explain the reasons for different physical media performing differently on a network Can discuss the advantages and disadvantages of using different types of physical media in terms of cost, performance and other factors Can explain why typical networks use a combination of different of physical media for communication in terms of cost, convenience and other factors Can draw conclusions about the choice of physical media in large networks in terms of both intra- and communications, and factors such as cost, performance, reliability and convenience Network security basics Understands that modern networks include security features but may not completely understand the need for it Understands the need for security in networks to ensure data is not altered or intercepted by third parties Can explain the need for security in networks in terms of data security and privacy, and can provide a simple description of basic Understands that network security is achieved through a approach, and can explain why more than one layer is necessary for the system to effectively maintain data Can hypothesise about the value of strong security measures to typical online activities such as banking, identity management and other critical services, and the implications of security
