Network

A network is defined as two or more computers that are connected together to allow access from one to the other.

A Local Area Network (LAN) is one in which machines are connected using physical cables. This is appropriate for machines that are located closely together, such as within an office or building.

Wide Area Networks (WAN) consist of computers that are connected together using dedicated digital lines or telephone lines, over a wider area where physical wiring is not possible. The purpose of a WAN is to allow an organisation to share data and hardware throughout all its locations in order to maximise the company's data processing investment.

A Virtual Private Network (VPN) uses the internet as a means of allowing machines to communicate, by using software to encrypt the information as it passes along the public wires. VPNs are cheaper to run than WANs, as they do not require dedicated lines.

Foremost have a great deal of experience in setting up and administering networks, and can offer advice on the hardware and software options available.
