Duplex Or Not To Duplex

[bobgo2728]

I am wondering if you should set your nic to do full duplexing or not to? I have heard it will burn your card out fast if you put it on full duplex, is this right or wrong?

Found this. I don't know if it makes a big difference, though

A half-duplex system provides for communication in both directions, but only one direction at a time (not simultaneously).

A full-duplex system allows communication in both directions, and unlike half-duplex, allows this to happen simultaneously.

Ethernet was originally based on the idea of computers communicating over a shared coaxial cable acting as a broadcast transmission medium.

From this early and comparatively simple concept Ethernet evolved into the complex networking technology that today powers the vast majority of local computer networks. The coaxial cable was later replaced with point-to-point links connected together by hubs and/or switches in order to reduce installation costs, increase reliability, and enable point-to-point management and troubleshooting. StarLAN was the first step in the evolution of Ethernet from a coaxial cable bus to a hub-managed, twisted pair network. The advent of twisted-pair wiring enabled Ethernet to become a commercial success.

No there is no advantage to limiting your card to half duplex if full duplex communication is supported.
