Setting Up a Basic IT System

2. Networks

2.1 If you work on your own, the only network you need 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 into all the devices. Check this before buying.

2.2 If you have more than one computer 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 machines at busy times.

2.3 If connecting your PCs is essential so you can share data with other users, you should build a network based around a server.

• The server is a dedicated computer that manages the network and stores software and users' files. It lets anyone on the network access other people's work when required (see Network servers).
• You must take preventive measures in case the server fails. At the very least, the server's contents should be backed up regularly. Ideally, get a server that's built to continue functioning even if components fail, as well as backing up regularly.
• As your network grows, it will take more time to manage. For maximum efficiency, make one person responsible for your IT (see Maintaining your IT system).
