Investigate how data is transmitted and secured in wired, wireless and mobile networks, and how the specifications affect performance
Elaborations
explaining that networks have components that control the movement of data, for example routers, hubs, switches and bridges manage data traffic and that the characteristics of these components impact on the operation (speed and security) of networks (Skills: Literacy, Information and Communication Technology (ICT) Capability, Critical and Creative Thinking)
explaining how cellular radio towers (transceivers) and mobile phones work together to create mobile networks (Skills: Literacy, Information and Communication Technology (ICT) Capability, Critical and Creative Thinking)
comparing the reliability and speed of transmitting data through wireless, wired and mobile networks (Skills: Literacy, Numeracy, Information and Communication Technology (ICT) Capability, Critical and Creative Thinking)
recognising that there are different communications protocols for transmitting data in networks, for example hypertext transfer protocol (HTTP) is used for transferring web page files in a browser, file transfer protocol (FTP) is used for sending and receiving any files over a network and transmission control protocol/internet protocol (TCP/IP) is used for controlling file transfers over the internet (Skills: Literacy, Information and Communication Technology (ICT) Capability, Critical and Creative Thinking)
