Computers can be connected using several methods. The most common method is to use data cables linked between the server and each workstation - but this can be expensive, ugly and cause damage to the decoration in the areas where the cables need to be run.
These wires are usually hidden inside plastic boxes called trunking or conduit. This is used to protect the wires from damage - and to look less ugly.
A new form of connection is now becoming popular - this method uses infra-red waves to link the different parts of the network together. It is then possible to connect to the network from outside or inside the building - even from the garden - as long as the workstation is less than about 100m away from a wireless hub.
Called "wireless networking" each device must be fitted with extra hardware - though some types of computer have these built in - such as the new iMac made by Apple. Read this BBC News article to understand how wireless networking is becoming popular: http://news.bbc.co.uk/1/hi/technology/2591181.stm
