What is port switching and segment switching?

PORT SWITCHING:- A Machine is directly Connected to the Switch's port..,so that you can run parallel full speed between machines....its an expensive solution since the unit price of switch per port is high!

SEGMENT SWITCHING:- A Whole segment is connected to the port of the switch..here you can either connect the workstation directly on the switches port or use segments to connect...Its is more effective switching compared to Port Switching!
