5. Server
This computer provides services to (it serves) a computer network. Services include letting people log in to the network, running programs for you, letting you save to a shared area, and letting you print and access the internet. We don’t use this computer on a daily basis.
Clients
We use these computers to access the services on a computer network. For example, to use programming software, such as Scratch or Kodu, or word processing software. Most of the time we have to log in to the network on these computers before we can use them.

6. Switch
This is used to join different devices on the network together so they can ‘talk’ to each other by exchanging data. The data travels along the cables which come out of this device.
Wifi point
This lets wireless devices (laptops or tablets for example) connect to the network. It works by passing data through the air using something called radio waves.
