port on the switch and the end-node are operating at the same speed and that they are communicating at the highest possible common speed of the devices.
Duplex Mode
Duplex mode refers to the way an end-node sends and receives data on the network. An end-node can operated in either half- or full- duplex mode depending on its capabilities. An end-node that is operating in half-duplex mode can either send data or receive data, but it cannot do both at the same time. An end-node that is operating in full-duplex mode can send and receive data simultaneously. The best network performance is achieved when an end- node can operate at full-duplex, since the end- node is able to send and receive data simultaneously.
The twisted pair ports on the AT-FS708LE switch can operate in either half-duplex or full- duplex mode. The switch sets the duplex mode automatically through Auto-Negotiation. With Auto-Negotiation, if an end-node is capable of full-duplex, the port is set automatically to full- duplex mode. If an end-node is capable of half- duplex, the port is set automatically to half- duplex mode.
