Hub vs Switch

>When my PC has TCP traffic, TCPflow picks it up. Why is that?

What you are witnessing is the difference between a hub and a switch. Incoming traffic from a hub will be broadcasted to any machines connected to it. Packets that are not intended for your IP are normally ignored, but packet sniffers log the receipt of the packet.

Switches only send packets to the machines that they are intended for.
