What is a network diagram?

A network diagram is a visual representation of a computer or telecommunications network. It depicts the components that make up a network and how they interact, including routers, devices, hubs, firewalls, etc. A network diagram may act as a broad overview or detailed illustration, depending on its scope and purpose.
