An introduction to computer networks
Lesson details
Learning outcome
I can describe a local network and its components.
Key learning points
- Devices on networks connect for communication and resource sharing.
- Networks rely on specialised hardware.
- Devices on networks perform different roles in order to exchange information.
Keywords
Network - a group of devices connected together, wirelessly or using cables, to enable communication
Server - a computer that stores, manages and shares files, data and resources in a network
Client - a device that requests services, files or resources from a server on a network
Router - a device that manages the flow of data between computer networks
Common misconception
On a network, servers, clients and routers have the same purpose.
Servers, clients and routers have distinct roles and functionalities in a network. They are not interchangeable and serve different purposes.
Teacher tip
Discuss the benefits of a local network in your learners' own lives. Ask them to think about how they use networks at home or at school for communication and sharing resources.
