Setting Up Your First IT System

2. Networks

2.1 If you are working on your own, the only network you need to consider is the connection between your PC, phone line (for Internet access), printer and possibly fax or copier.

• This should be easy to set up, as connectivity should be built in to all the devices. Check this before making the purchase.

2.2 If you have more than one computer and fewer than eight, you can consider linking them through a peer-to-peer network.

• Each user can access the other users' machines and external devices. This may slow down some users' machines at busy times.

2.3 When your business has more than six connected PCs, you should build a network based around a server.

The server is a dedicated computer that manages the network and stores software and files created by users. It allows anyone on the network to access other people's work when required.

• You must take preventative measures in case the server fails. At the very least, the contents of the server should be backed up regularly. Ideally, you need a server that is built to continue functioning even if components fail, as well as backing up regularly. For maximum efficiency, make one person responsible for your IT.
