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
