Create a network diagram using free templates and symbols provided by EdrawMax and EdrawMax Online. A Network Diagram is a visual representation of network architecture as it maps out the structure of a network with various symbols and line connections. As illustrated below, a network diagram is an ideal way to share the layout of a network because the visual presentation makes it easier for users to understand how items are connected. In the diagram, the workstation is connected to a File Server, a central server in a computer network that provides file systems or at least parts of a file system to connected clients. Therefore, file servers offer users a central storage place for files on internal data media, which is accessible to all authorized clients.
