Networked computer

A network allows you to connect two or more computers together. This allows data stored on one PC to be retrieved by other PCs connected to the network.

It also allows the sharing of resources. Thus instead of each PC requiring its own printer to be directly connected to it, you can have a single printer shared amongst many networked PCs.

In the early days, to network PCs together was a complicated task, only to be attempted by qualified professionals.

These days most people with a good working knowledge of Microsoft Windows can install and configure a Windows based network.

However to get the best out of your network, in terms of performance and security, still requires a qualified, experienced technician.
