It is a twisted cable (twisted pair).  Do you mean a crossover cable?

Assuming a crossover cable is needed for the NIC to the switch, why does a connection from
the switch to the hub only work if the "straight" cable is plugged into the
hub's uplink port and a regular port on the switch?

Just trying to understand.
