What is a Network Diagram?

Updated

A network diagram is a simple drawing that shows how all your business technology connects together. It's like a map of your computer network that includes:

  • Your internet router
  • Computers and laptops
  • Card payment machines
  • Printers
  • Security cameras
  • Any other connected devices.
  • What does it look like?

It can be as simple as boxes (representing devices) connected by lines (showing how they connect). You don't need to be an artist — just clear about what connects to what.

Why do you need one?

  • To show exactly how your devices are connected
  • To help IT support fix problems faster
  • It is required for security compliance
  • It is critical if you have a security breach — investigators need to see your network layout
  • It helps you identify security weak points

How to create one:

  • Use online diagram tools (many are free)
  • Draw it by hand on paper
  • Be sure to update it whenever you add or remove devices
  • Store it somewhere safe but accessible.

Think of it like a floor plan for your technology — it helps everyone understand how your digital systems are organized.
