These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Networks allow devices to share resources and communicate efficiently.
- Networks also have drawbacks, such as security risks and maintenance costs.
- In a peer-to-peer network, each computer can share resources directly.
Keywords
Client - a device that requests services, files or resources from a server on a network
Server - a computer that provides services, files or resources to clients over a network
Peer-to-peer - a type of network where each device (peer) can act as both a client and a server, sharing files and resources directly without a central server
Common misconception
All networks must have a server because a server is always needed to share files or printers between devices.
Not all networks need a server. In a peer-to-peer model, each computer can act as both client and server, sharing files directly. This setup is simpler but may lack central control and security.
