Loopback in Half Duplex

?Half-duplex Ethernet uses a loopback circuit to detect collisions? Is this mean I need to configure a loopback interface to make collision detection work? If yes, where to set that loopback interface? On the switch? Or host? Actually, I normally don?t need to create loopback interface when I plug my computer with hub. How this works? I just don?t understand that statement.

You do not need to create any loopback interface. The book you are reading is explaining the technology in how a switch detects that there is a collision. This is a hardware mechanism in switches and we do not have to configure anything for this
