Engineer Briefing

Welcome back, Engineer.

In Module 1, you learned:

• What networks are.
• The devices that build networks.
• The models engineers use to understand communication.

Now we go deeper.

"I sent a file to my colleague."

But a network engineer asks:

"What exactly travelled through the network?"
