By the time you read this theory section you should already have learned quite a lot about computer networks.
You certainly should understand the difference between a LAN and a WAN.
Depending on the GCSE syllabus that you are following, you might also be able to describe the different network topologies - star, bus and ring (don't worry if you haven't covered this).
Now you are going to find out about client server and peer to peer networks.
These are not to be confused with LANS and WANs or star, bus and ring layouts. Instead, client server and peer to peer networks are more to do with how files and data are stored on the network and how they are accessed or retrieved by the person using the network.
