Please consider the following image:
I randomly wandered into the telecom room at work a while ago, and I noticed these strange looking terminals. How do you terminate a wire like this? Is there a certain tool to create the coil around the terminal? What do I call this sort of terminal?

This is called Wire Wrap. The low resistance connection is made by cold-welding the wire to the pin at the corners of the pin.
There is a special tool for making wire wrap connections.
Here's a tutorial video. [Nothing special about it. This is the first one I've come across.]
