Hi,

A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. ...

Depending on whether the diagram is intended for formal or informal use, certain details may be lacking and must be determined from context. ...

At different scales diagrams may represent various levels of network granularity. At the LAN level, individual nodes may represent individual physical devices, such as hubs or file servers, while at the WAN level,individual nodes may represent entire cities. In addition, when the scope of a diagram crosses the common LAN/ MAN/ WAN boundaries, representative hypothetical devices may be depicted instead of showing all actually existing nodes."

The organizational chart software is a valuable tool for modern business. It is important for any business to build a clear organizational structure that determines the responsibilities and relationships between different positions in the organization. The clear structured organization - means the clear structured business workflow, which is the core of success in the business. ConceptDraw PRO is an org chart software that allows you to draw an organizational structure of your company quickly and easily.

Hope this helps

Wish you luck
