Discovering computer networks: hands on in the Open Networking Lab

Summary of Week 1

Week 1 introduced you to home networks and how each device on the network has a unique address.

You should now be able to:

  • identify your home network as a local area network – defined as a group of computers and devices connected together in a small geographical area
  • understand how the devices are connected together
  • begin to think constructively about how these devices communicate with each other
  • understand that an IP address has a network part (common to all devices on the network) and a unique part for device (or host)
  • recognise that a subnet mask of 255.255.255.0 indicates that the final number of an IP address represents the device
  • diagnose local network problems caused by incorrect IP addresses and non-allocation of IP addresses.

Next week you will look at how data is moved across the network between devices.
