1 1 I NTRODUCTION This chapter introduces the D-Link DES-2218 switch, and the technologiesthat it uses to give you improved network performance and reliability. DES-2218 Ethernet/Fast EthernetSwitch The DES-2218 is an Ethernet/Fast Ethernet switch for networks needingimproved performance, the abilit...

2 Introduction All of the ports can operate in either half-duplex or full-duplex mode. Full-duplex operation, allowing the port to transmit and receive at the same time,can double overall network bandwidth in many applications. Switching The DES-2218 uses store-and-forward technology to bridge packe...
