​Introduction to computer networks

​Two or more devices are connected together using networks.Files are sent from one device to another in the form of data packets. A file sent over a network is broken into small chunks of data known as data packets. These data packets are transmitted by the sender.
At the receiver end, the file is re-built by arranging data packets in order.
Protocols define the set of rules that control the way the data is sent over the network.

This ​A Level Computer Science module introduces ​​computer networks to your students, explaining:

  • ​A network and its types
  • Wired and wireless networks
  • Hardware components required for networking
  • Different types of routing
  • Wi-Fi
