You've learned about the audio and video technologies that form the core of the AV industry. More and more, though, those AV technologies rely on IT technologies to work. Modern AV systems use IT networks to support their systems in all kinds of ways. Technicians can monitor, control, and troubleshoot devices over the network. AV content is stored on the network. Audio and video signals can be distributed over network infrastructure in real time. Realizing the potential of networked AV systems requires you to work very closely with IT professionals. You need to be able to “talk the talk” to explain your needs and understand their concerns. In this module, you'll begin to explore networks by looking at how they are laid out.
