Years 5–6 Digital Systems · Modules 31–40 · Student wording will vary for definitions
1modem — A device that converts signals so a local network can connect to an internet service provider (ISP), such as over an NBN connection. A router then shares that connection.
2wireless access point — A device that connects to a wired network and broadcasts a Wi-Fi signal so wireless devices can join the network.
3IP address — A unique number that identifies a device on a network, like a postal address, so data knows where to go. IPv4 looks like 192.168.1.5.
4packet — A small chunk of data with the sender, destination and order number attached. Packets travel a network by different routes and are put back in order at the destination.
5protocol — An agreed set of rules that devices follow so they can communicate, like HTTP for web pages. Both devices must use the same protocol to understand each other.
6bandwidth — The amount of data a network connection can carry in a given time, usually measured in Mbps. Shared by all users, so more people or video streaming means less speed each.
7data path — The route data takes across a network, passing through devices like a router and ISP from the sender to the receiver (a server), then the reply travels back along the route.
8personal data — Information that identifies or relates to a specific person, like their name, birthday, address, photos or location. It needs protecting because it is stored in online accounts.
9digital account — A personal record kept on a system, like a school, email, game or social account, that you must log in to reach. Each account holds your own information.
10username and password — A username identifies who you are and can be shared. A password proves it is really you, so keep it secret and never share it. You use both together when logging in.
